1,4 dioxane Testing in Cosmetic Products

Various tests and analyzes are carried out to ensure the safety of cosmetic products. The 1,4 dioxane Test is also a method of ensuring safety by looking for 1,4 dioxane, an impurity that can be found in trace amounts in products such as shampoos, deodorants, toothpastes, and mouthwashes.

The general opinion is that the amount of 1,4 dioxane should be at trace levels of ≤10 ppm in cosmetic products. In fact, 1,4 dioxane is not used as an ingredient in cosmetics and personal care products, it can form as a by-product in the manufacturing process of some ethoxylated cosmetic ingredients such as detergents, foaming agents, emulsifiers or solvents.

In order to ensure product safety, 1,4 dioxane Test should be carried out in cosmetic raw materials and finished products for consultancy in the production process, toxicological evaluation, obtaining the necessary information in the labeling of cosmetic products, and determining their compliance with the relevant regulations and guides.
