Knowledge is Power: Creating a Database of Reconstructed Oral Tissue Model Applications for Personal Care Industry and Beyond
…Megan Creelman and Gertrude-Emilia Costin
The personal care industry is an ever-expanding field of products that come into contact with our mouths daily, such as lipsticks, toothpastes, mouth-washes, and whitening products 1,2 W ith a multitude of new products being released each year, how are they all being evaluated for consumer safety? One option that has become increasingly popular is that of 3D (threedimensional) reconstructed human tissue models 3 These models are comprised of layered, differentiated cells intended to replicate various phenotypes of human tissue, thus making them relevant for replicating the response of native tissues to various types of products topically applied While some academic laboratories are creating such tissues in-house, not all are equipped to handle large-scale productions, and as such there are a few companies that provide these tissues commercially 4
As an easily scalable platfor m for toxicity testing, it is crucial to be aware of all the applications for such tissue models to avoid the unnecessary or premature use of expensive, time-consuming, or potentially unethical animal or human testing This is what prompted us to compile a comprehensive database of academic sources discussing all manner of use cases for one such category of tissue models We primarily focused on commercially available models given their production under strict manufacturing conditions that make them standardized, reliable, and in some cases validated test systems generated within established, acceptable biological perfor mance ranges
n Tissue Models and Providers
The tissue production process has been optimized commercially for a wide variety of phenotypes, including but not limited to dermal, ocular, buccal, gingival, and vaginal tissue models Each phenotype has a plethora of use cases to be found in the safety testing of personal care products; however, we chose to focus solely on those models most relevant to oral applications buccal and gingival

For these two phenotypes there are several commercial providers (Table 1), of which two might be considered primary suppliers of these tissues based on the considerable number of published peer-reviewed papers or posters captured in our database: EpiSkin (Lyon, France) and MatTek Corporation, now part of Sartorius (Ashland, MA, USA). EpiSkin produces the (continued on Page 4)

Letter from the Chair …Anushka
Spring has sprung, and the energy across the NYSCC continues to build. From education and outreach to industry engagement, it has already been a very productive and inspiring year.
In March, we hosted The Beauty We Build: DIY-ing DEI in Beauty, which was a tremendous success Held fittingly at Maxwell Social, a private club built for nurturing communities, the program sparked thoughtful discussion and meaningful dialogue around diversity, equity, and inclusion Programs like this remind us that innovation is not only about new ingredients and technologies, but also about building a more inclusive and representative industry

Our Future Chemist Workshop Committee also held its first “ on the road” formulation program at NJIT as part of National Engineers Week It was an incredible event with strong student participation and a great example of our commitment to supporting and inspiring the next generation of cosmetic chemists
Looking ahead, we are excited for our upcoming Sustainability Symposium this month. Sustainability remains one of the most important focus areas for cosmetic scientists and product developers, and this program will bring together experts from academia, brands, and across the supply chain to discuss practical solutions and responsible approaches shaping the future of beauty and personal care Education remains at the core of NYSCC’s mission, and this symposium is a great example of the high-quality programming our volunteers deliver.
We also look forward to participating in MWSCC Teamworks in Chicago, which highlights the collaboration and strong connections across SCC Chapters and creates valuable opportunities for knowledge sharing and professional growth.
On the global front, we are thrilled to continue our inter national outreach with our upcoming Press and Friends Breakfast in Paris. Following the success of our January event in Miami, these gatherings help us connect with media, industry leaders, and partners from around the world as we build momentum toward Suppliers’ Day
And of course, May will be here before we know it, and we are incredibly excited for NYSCC Suppliers’ Day, May 19th–20th at the Jacob K Javits Convention Center in New York City. W ith nearly 700 exhibitors, our largest exhibit floor to date, and more than 100 hours of education and programming, Suppliers’ Day showcases the very best of our industry from breakthrough ingredient technology and for mulation science to marketing insights, sensory experiences, and global trends. This year ’ s theme, Breaking Beauty Boundaries with Science, truly comes to life across the entire event from for mula to finish If you are planning to attend, I encourage you to register in advance, review the conference program, and begin mapping out your schedule so you can make the most of this week of beauty

SkinEthic™ Human Oral Epithelium (HOE) model and the SkinEthic™ Human Gingival Epithelium (HGE) model, while MatTek Corporation produces the EpiOral™ and EpiGingival™ models, which represent the buccal and gingival phenotypes, respectively Histologically, these cultures are similar to each other and have been shown to replicate the respective human native tissues well. Two other commercial providers (Creative Bioarray and Sterlab Store) offer their own reconstructed models that replicate the buccal or gingival tissues (Table 1) Finally, REVIVO BioSystems recently made available an in vitro oral barrier-on-chip, which provides a complex testing platfor m to be used for but not limited to the investigation of oral diseases Depending on their geographic location, the perfor mance of these test systems needs to be evaluated through shipping studies and their reliability for toxicological studies should be assessed for the endpoints of interest 5

Conclusions:
The nanoparticles did not penetrate the gingival stratum corneum and only the outermost layer of cells in the oral epithelium. No permeation into the deeper layers of the epithelium was observed for either model. The nano-hydroxyapatite particles were observed in the cytoplasm and extracellular matrix of the outermost cells in the non-cornified model, but they were not observed in the deeper layers. The stratum corneum acts as a barrier to penetration of nano-hydroxyapatite into the oral epithelium and nano-hydroxyapatite is unlikely to enter systemic tissues with an intact oral epithelium.

The oral model was found to be more sensitive than gingival model. Increases in IL-1! expression correlate with cell membrane damage. IL-1! may be more difficult to detect in shorter exposure times due to the time needed for the diffusion of this marker into the medium.

Across all categories, some of the most common materials tested were ingredients specific to final for mulations of typical oral care products, such as toothpastes, mouthwashes, and whitening products. These personal care categories also align with common products within a consumer ’ s household, thus demonstrating the necessity of safety testing. As the demand for oral care products rises, though, so too does the rate of manufacture of new products
For each new for mulation created, the active and inactive ingredients within must be approved for use up to certain concentrations (monographed). However, any possible synergistic effects from varied ingredient combinations may not be predefined and thus due diligence safety testing remains an ideal step in the preparation of novel products.6 7 In these cases, the first step is to consult existing literature for ingredient combinations and concentrations like the envisioned product design This is where having a curated database is exceptionally useful, as it is timesaving and significantly more efficient than perfor ming research from scratch each time a new product is developed
W ith the ability to sort the extensive list of sources by the specific ingredients classes tested, type of endpoints, or tissue model, any relevant publications can be accessed within seconds. By perfor ming a preliminary search, the existing plan for a for mulation could be adjusted based on results reported by p
knowledge arsenal
n Tissue Model Comparisons
A curated database of relevant sources also offers ease of comparison between tissue models that might be relevant for safety testing and for offering a complete profile of a new oral care product For example, when designing a cytotoxicity study for a new material, the tissue model chosen is integral to the success and applicability of the assay conducted The choice between a buccal or gingival phenotype is key to human accuracy in a clinical trial, and it is one best made from a highly infor med position Further more, for companies familiar with a particular tissue model or that have already established a database based on one, it is most prudent to continue using the same test system This is also particularly important when benchmark/reference materials have also been used historically to evaluate or qualify the test system, as the safety assessment needs and their acceptable ranges have been established with a particular tissue model.
Using our database, we were able to quickly identify the sources that compared the use of buccal and gingival phenotypes from the same provider Most of these sources compared the EpiOral™ and EpiGingival™ models provided by MatTek Corporation; however, there were some that compared the two phenotypes provided by EpiSkin as well (this example is provided in Figure 1), and even a few sources that compared the same phenotype from each provider. These comparative studies also allow the selection of the tissue model that best fits the needs of the testing to be conducted or to establish alter native options for models with similar perfor mance, should there ever be a need to use one or the other alter natively
Surfactants and oral care products were the most common materials tested in the intra-provider phenotype comparisons, thus offering plentiful references for deciding which option is the most relevant for each new product By choosing the most fitting model from the start, it is possible to eliminate wasted time and resources and thus allow for more efficient development.
n New Applications of Oral Reconstructed Tissue Models
While most of the publications identified during the creation of this database included what could be considered “standard” testing for viability, cytotoxicity, or histology, there was a significant number of articles that reported about applications for the tissues that are recently gaining popularity within the commercial safety testing field
One of the applications that is of particular interest is the safety testing of oral medical devices As the creation of this product class is beholden to different requirements than the design of a new toothpaste formulation, so too can it require different safety evaluation strategies, which can often involve animal testing and clinical trials While clinical trials cannot be entirely substituted, replacing animal testing with in vitro testing methods is possible, as it is more cost-effective, human-relevant, and ethical.
Currently, EpiSkin and MatTek Corporation provide reconstructed human epider mis models that are validated for assessing the cytotoxicity of medical device extracts (ISO 10933-23, 2021), however the
oral models are not yet approved for this same purpose.8 If an effort were to be made to validate the oral models commercially available (Table 1) for medical device cytotoxicity testing, an archive of previously tested medical devices would be an exceptionally useful tool
Another evaluation that could be particularly useful in conjunction with both new product development and medical device testing is based on the exposure of tissues to irradiation All studies that investigated the response of the tissues to this exter nal factor reported that there was a clear doseresponse to the treatment W ith this knowledge, the irradiation could be applied in tandem with other safety and efficacy endpoints for the evaluation of Sun Protection Factor (SPF)-containing products, for instance Irradiation could also be an infor mative treatment to include in the testing of certain medical devices such as adhesive dental primers, which are light cured 9
Lastly, a frequently reported testing approach (in approximately 20% of sources) captured in our database was application or culture of bacteria, viruses, or fungi on the tissues For the most part, bacterial species naturally occurring in the oral space were tested, like Candida albicans. This method is most applicable for the study of oral infections rather than the development of oral care products; however, it opens a new realm of possibilities for other fields that could benefit from these human test systems By compiling all the sources that test a common strain, like C. albicans, it may be possible to create a standardized methodology based on the multitude of results obtained in laboratories worldwide
n Key Takeaways
• There is a wealth of infor mation available to the scientific community and the public at large, so a tool such as a curated database is especially useful to wade through the mire of data and quickly and efficiently locate the most relevant sources for a project or product design
• To make the most infor med decisions possible during product development and to avoid incurring extra costs or elongating projects, a comprehensive list of academic references is a highly cost-effective tool for perfor ming preliminary research
• The process of creating this database alone was a worthwhile and enlightening endeavor, not only because it is an advantageous tool but also because several novel applications were brought to light The database captures the scientific knowledge existing at the moment of its inception and therefore requires maintenance or updating every several years to keep its relevance and infor mative usefulness
n Conclusions
While the construction of the database was time-consuming and meticulous, we consider that the degree of depth of research was justified by the abundance of sources that are now easily accessible. This effort has made the sharing of this resource possible for the benefit of the entire scientific community New materials and applications are perpetually in development and could profit from the use of these in vitro reconstructed human tissue models, so it is vital to remain balanced on the cutting edge of this rapidly expanding field to ensure that this type of test system is explored and used to its fullest potential

No Tears, No Compromise: Advancing Cosmetic Eye Safety
…Sarah Risse and Janina Tiemann-Hesselbarth
The Gap: Why Standard Tests Often Fall Short for Moder n Cosmetics
This year ’ s NYSCC theme, Breaking Beauty Boundaries with Science, highlights just how important robust results from scientific test designs are for the cosmetics industry. Trust, along with a commitment to sustainability and ethics, is becoming increasingly important to an increasingly infor med and discer ning consumer base and is becoming a decisive factor in the acceptance and long-ter m success of cosmetic products The question for testing institutes such as Der matest is whether established standards are still sufficient for cosmetics manufacturers, and how new, innovative methods can best support moder n cosmetics.
Der matest has conducted an in-depth examination of testing procedures for the tolerability of the ocular mucosa, demonstrating that there is a methodological gap for cosmetic products and that both scientific and ethical limitations must be considered in conventional test designs 1

Established methods include the Bovine Cor neal Opacity and Per meability (BCOP, OECD TG 437) test, which uses corneas from slaughtered cattle; and the Hen’s Egg Test – Chorioallantoic Membrane (HET-CAM), which utilizes the vascular reactions of incubated chicken eggs 2-5 While these methods are suitable for identifying severe irritants, they continue to rely on animal material, which complicates their transferability to the human eye. Another approach is the human ocular instillation test, which, although it measures directly at the target organ, is highly problematic from an ethical standpoint due to its invasive nature and the risk of eye damage.6
The current regulatory gold standard is OECD TG 492 7-9 Although OECD Test Guideline 492 uses advanced reconstructed human cor nea-like epithelium (RhCE) models, it presents a diagnostic gap for the cosmetics field The method is widely used for general chemical hazard assessment and provides only a binary outcome, identifying substances as either “No Category” or requiring further evaluation, without distinguishing between different levels of eye irritation.
Cosmetics, however, have different requirements The question is not whether a cosmetic product is irritating or highly damaging. What matters instead is how gentle a product is on the eyes. This is particularly relevant for products designed for the face and hair or aimed at particularly sensitive user groups such as babies Here, testing standards are required that offer a far higher resolution to identify subtle differences in the ‘mild’ to ‘extra-mild’ range. This is a level of precision that OECD methods cannot provide due to their single-point measurement of vitality
n The Solution: The Der matest ‘No Tears’ Test Design
To address this gap, Der matest has established the ‘No Tears’ test design This approach utilizes the same advanced RhCE tissue technology as the OECD methods and is based on the published definition of the ET50 value for classifying the mildness of products into the categories non-irritating-mild-moderateextreme 1,10
The results are presented via the ET50 value (Effective Time), which plots the relationship between tissue vitality and exposure duration on a linear scale, thereby precisely demonstrating the degree of mildness of a product The metabolic activity of the cells is precisely quantified using the colorimetric MTT assay. Consequently, the test design allows for a differentiated assessment between surfactantcontaining cleansing products (e g , shampoos) and surfactant-free products such as eye serums This
flexibility ensures that the exposure scenarios correspond to real-world use.
Products that successfully pass this certification process may be awarded the Der matest ‘No Tears’ seal (Figure 1) It serves as an evidence-based quality indicator that goes far beyond simple marketing claims and guarantees the end consumer scientifically proven gentleness.

n The Benefits: Where Science Meets Trust and Transparency
Der matest’s No Tears fills the existing gap and offers the possibility of clearly and precisely demonstrating the mucosal tolerance of cosmetic products Compared with all other common methods, Der matest’s No Tears offers decisive advantages (Table 1): The data are objective and reproducible. The test design can be individually adapted, allowing a wide range of leave-on and rinse-off products to be tested The transferability of the results is guaranteed using a human cell model
Table 1 Characteristics of eye safety test designs


No Tears is a moder n testing approach that fulfils the requirement to inextricably link scientific rigor with ethical responsibility. It offers a 100% animal-free solution that does not rely on animal models or invasive testing on human subjects W ith almost 50 years of experience in der matology, science, and cosmetics, ethical testing and scientific responsibility for m the foundation of all services provided by Der matest
The Der matest ‘No Tears’ seal thus offers manufacturers a scientifically sound and transparent way to demonstrate the properties of their products, whilst simultaneously creating a credible basis for communication and fostering trust between manufacturers and increasingly well-informed end consumers

TThe Time Capsule –An Interview with Henry F. Maso
here is an inter net resource known as the Wayback Machine (https://web archive org) It archives one trillion web pages, a few of which are from the NYSCC websites of the 1990s
The Time Capsule contains personal views of the past, present, and future state of the cosmetic industry written by for mer chairs of the NYSCC chapter Each statement deals with broad issues of historical and/or scientific interest

Starting in 1998, the Cosmetiscope under the project named “The Time Capsule” interviewed four industry leaders about the state of the cosmetic industry: Ken Klein, Henry F Maso, David C Steinberg, and Paul Thau. This was fortunately captured by the Wayback Machine. Last month, we printed an interview with Ken Klein This month, we bring you an interview with Henry Maso
n About the Interviewee
Henry F Maso was a consultant and principal of H F Maso Associates He was also a Senior Research Scientist at Johnson & Johnson and Senior Vice Presid at Amerchol Corporation. In addition to chairing the New York Chapter, h served as president of the Society of Cosmetic Chemists (SCC) and of the Inter national Federation of Societies of Cosmetic Chemists (IFSCC).
n Remarks by Henry F. Maso
I believe that the most significant advances and contributions to personal care technology have occurred in the enor mous proliferation of ingredients now available to the cosmetic chemist.
When I first became involved in this industry in 1944, there were only a few hundred ingredients available for the relatively primitive technology of the early 1940s. Today there are over 9,000 ingredients and over 14,000 trade names in the CTFA-INCI Dictionary This spectacular expansion o ingredient technology has been truly mind boggling in its complexity a creativity, and I am glad that I was able to be a witness to this industrial gr and development in personal care

While numerous innovations have occurred in surfactants, synthetic oils, polymers, silicones, botanicals, "active" ingredients, and many other areas, there is one area, a particular favorite of mine, that I wish to emphasize. I refer to "hydrophobically modified polymers." I think these should be described more accurately as "lipophilically modified polymers " The development of this group of ingredients has had a major impact on emulsion stabilization. They have provided structural stabilizing effects which minimize dependence on conventional emulsifiers In my opinion, these polymeric stabilizers have not yet achieved the full recognition they deserve Many new lipophile-modified polymers are being developed that will make these emulsifying polymers the most significant contribution of the past decade to emulsion technology
In contrast to conventional oil-in-water (o/w) emulsifiers, the bulky configuration of the polymer backbones limits the extent of positioning of their lipophiles in interfacial films However, these modified polymers have a unique stabilizing effect on inter nal oil phases and dispersions because of their associative activity The lipophilic side chains, essentially foreigners in the aqueous environment of an o/w emulsion, bond together for ming cells which entrap inter nal phase droplets or particles Lipophilemodified polymers have proven to be powerful stabilizers for o/w systems, and in some instances practically eliminate the need for conventional emulsifiers The main backbones currently used for these modifications are hydroxyethylcellulose and acrylate copolymers, but the future should bring us many new developments in this technology
