Industrialists of the cosmetic sector, you wish to analyze and characterize the zinc oxide (ZnO) in your products
What is ZnO in cosmetics?
Zinc oxide (ZnO) is particularly used in sunscreens for its antibacterial and deodorant properties, but above all, as a refractor of UV rays.
Indeed, where many sunscreens absorb UV rays, zinc oxide has the property of forming a barrier to refract UV rays. This explains the white color of mineral sunscreens.
Why analyze and characterize zinc oxide (ZnO) in your cosmetic products?
According to a joint study by researchers from the Universities of Leeds (UK) and Oregon (USA), zinc oxide, in combination with certain other ingredients, rapidly loses its effectiveness and could even be harmful to the skin.
Indeed, under certain conditions, the presence of zinc oxide in the composition of a sunscreen would lead to a significant decrease in its action against UVA rays – which penetrate deep into the skin and can cause wrinkles, spots, precancerous lesions and skin cancers.
Thus, the support of a laboratory specialized in the analysis and characterization of zinc oxide in cosmetic products is a considerable asset.
FILAB supports you in the analysis and characterization of zinc oxide in your cosmetic products
FILAB is a laboratory staffed by experts in cosmetic analysis. It offers analytical services from the design to the manufacturing and marketing of cosmetic products (make-up, creams, perfumes, etc.).
FILAB is notably accredited ISO 17025 by COFRAC for the analysis of heavy metals, phthalates, 1,4-dioxane and bisphenol A in cosmetic products (www.cofrac.fr).
