About
Ethoxylated lanolin (sheep-wool wax) used as an emulsifier and rich emollient. Effective but carries lanolin-allergy and 1,4-dioxane caveats.
PEG-10 lanolin (CAS 61790-81-6) is lanolin (the wax-like secretion from sheep wool) modified with about ten ethylene-oxide units to give it surfactant and emulsifier function. Used in heavy creams, hair conditioners, and shaving products for its emollient and water-holding properties. Lanolin allergy is well-documented (positive patch-test rate around 1-3% in dermatitis populations). Ethoxylation can introduce trace 1,4-dioxane (a probable human carcinogen) unless suppliers strip it. CIR considers PEG-lanolins safe with controlled dioxane levels. Not vegan; sustainable-sourcing claims vary.
