Skin Irritation tests – tendencies and methods
Consumers today are becoming more aware of ingredients used in cosmetic products and their effect on skin health. This awareness is even more crucial to people suffering from sensitive skin conditions. In the past, claims such as "hypoallergenic" or "safe for sensitive skin", were commonly used, but today thanks to legislation and regulations, such claims cannot be stated without proofs and tests.
Eurofins - Dermscan, a leading international group of laboratories are sharing important information about skin irritation testing methods.
"The most common test for skin irritation is a 24-48 hour in vivo patch test done on 20 to 30 volunteers with sensitive skin. The patch test valuates the irritation potential after a single application of the product, this method can be performed only after eliminating from the product ingredients that are considered as allergens."
"In vitro tests using reconstituted human epidermis model are used in lip and eye irritation tests. Overall, we see substantial growth in skin irritation tests requests, from different markets such as US, Europe and Asia, due to changes in legislation and the marketers need to proof the safety of the product and marketing claims. We also see a growing demand for safety tests done by manufacturers of raw materials." Says Julien GRAS, Eurofins-Dermscan's export manager.
