Food allergen testing for cosmetics【Free technical materials available!】
Measures to reduce the risk of food allergy onset due to transdermal sensitization! Comprehensive testing available for 27 food allergens subject to domestic labeling!
Exposure to food allergens through the skin has been reported to trigger food allergy reactions to those foods later on. One of the causes of food allergy onset due to this transdermal sensitization is cosmetics. However, the method widely used for testing food allergens, as notified by the Consumer Affairs Agency, is designed with the premise of targeting food products. Therefore, when testing samples other than food, such as cosmetics, there is a concern that the influence of inhibitory substances not anticipated in food could arise, potentially hindering accurate assessment of the results. In response, our company has accumulated verification data for food allergy (allergen) testing using cosmetics as samples and has established a system to propose testing. 【Technical Documentation Available for Free!】Regarding the application of food allergen testing methods to cosmetic samples To verify whether the food allergen testing method of the Consumer Affairs Agency can also be applied to cosmetic samples, we conducted additive recovery tests. We are currently offering a summary of the results in a technical document for free. ★If you would like the document, please download it from the link below or contact us.
basic information
The following tests are available. *In accordance with the Consumer Affairs Agency notification law. ■ELISA Method This method detects specific proteins for each item through antigen-antibody reactions. It has been reported that false positive reactions may occur depending on the type and nature of the sample, and confirmation tests are conducted as necessary. ■PCR Method This method detects specific DNA for each item. In tests related to items with labeling obligations, it is used as a confirmation test (qualitative test) when a positive reaction is obtained with the ELISA method. For items recommended for labeling, many analytical methods based on this method can also be seen. ■Western Blot Method While it also detects through antigen-antibody reactions like the ELISA method, it has higher specificity due to the information obtained about molecular weight, making false positives less likely to occur. 【Features】 Our company has independently developed tests for food allergens such as "orange" and "gelatin (pork-derived)." Additionally, we widely accommodate food allergens from nuts.

Applications/Examples of results
■Acceptable Sample Types Cosmetics, food, etc. *The following types of samples may not be accepted due to the inability to conduct tests: - Samples that do not dissolve or disperse in water (lipstick, petroleum jelly, etc.) - Samples that react with water and produce foam (bath additives, foaming facial cleansers, expanding agents, etc.) - Samples for which it is difficult to perform the ELISA method (thickening polysaccharides, other substances that solidify into a gel-like state) ★Comprehensive testing of food allergens subject to labeling in a single test We can test all 27 items of food allergens subject to domestic labeling, excluding "ikura" (salmon roe). In addition to individual requests for items such as wheat and soybeans, we can conduct comprehensive and efficient testing of food allergens. ★More accurate protein measurement with additive recovery testing If you want to measure protein concentration more accurately for individual samples, we can also propose additive recovery testing. In additive recovery testing, we will report the total protein concentration in the sample, recovery rate, evaluation of the recovery rate, and concentration after correction for recovery rate.
