Expert Verdict
1,4-Dioxane contamination (byproduct of ethoxylation) and residual ethylene oxide - both are known carcinogens. Must be stripped/purified during manufacturing. NY state enforces ≤2 ppm 1,4-dioxane (dropping to 1 ppm) in finished products.. Nonionic surfactant/emulsifier. The 20 EO units give a high HLB (~15-16), making it an effective O/W emulsifier. Isostearyl chain provides branching that improves skin feel versus linear steareth-20.
Frequently Asked Questions
Is Isosteareth-20 safe in cosmetics?
1,4-Dioxane contamination (byproduct of ethoxylation) and residual ethylene oxide - both are known carcinogens. Must be stripped/purified during manufacturing.
