Protein Testing for Cosmetics
Overview
A wide range of plant proteins are used in cosmetics, such as wheat protein rice, oats, sunflower, almond and peanut, and soy globulin. Some peptides offer a possible way to temporarily improve skin firmness and thus reduce the appearance of wrinkles. Some proteins may be a source of type I food allergens (especially wheat proteins). Exposure to them may cause adverse reactions (asthma, itching or anaphylaxis) and are therefore classified as "new allergens". Due to their potential allergenicity, the amount and type of proteins present in raw materials must be determined by accurate and robust analytical testing.
Specific Services We Offer
Our biochemists use a variety of analytical methods for the robust and sensitive quantification of proteins in cosmetic ingredients. Methods include the CBQCA (3-(4-carboxybenzoyl)quinoline-2-carbaldehyde) method using a fluorescent enzyme marker and the bicinchoninic acid (BCA) assay. Using these methods, we can accurately determine the total protein in cosmetic ingredients (oils, waxes, powders, aqueous solutions, and cellular solutions). As the trend toward natural ingredients continues and more novel peptides and proteins are being explored for cosmetic formulations, understanding the scientific methods for these complex ingredients, such as total protein content, can support your product development, raw material selection, or production quality control.
Our Total Quality Assurance Solutions
Our cosmetic testing experts provide a comprehensive toolbox of quality assurance solutions for cosmetic testing, supporting your value chain from raw material sourcing, through the manufacturing process to the finished product. We offer responsive analytical resources to ensure consistent raw material quality and technical consulting to resolve production issues. Our dedicated analytical testing resources are combined with our combined strengths in research, regulatory guidance, and label review.
Advanced Protein Testing Technology
With advances in technology, protein testing in cosmetics has evolved to include innovative techniques. For example, proteomics, the study of whole proteins in a sample, enables a comprehensive analysis of protein composition, modifications, and interactions. This advanced approach provides greater insight into the function, stability, and potential interactions of proteins with other cosmetic ingredients.
Safety Assessment
Protein testing involves a rigorous safety assessment to evaluate the potential allergenicity and irritation of the proteins used in cosmetics. Allergic reactions to proteins are a concern and it is important to identify proteins that may trigger adverse reactions in sensitive individuals. In vitro tests, such as enzyme-linked immunosorbent assays (ELISA) or cell-based tests, can be used to accurately assess the allergenicity and sensitizing potential of proteins.
