About Emollient Ingredients
Emollients soften and smooth skin by filling gaps between skin cells and reducing transepidermal water loss. They form the backbone of most moisturisers, creams, and lotions. Most emollients are well-tolerated, but some — particularly plant-derived oils — contain proteins or compounds that can cause reactions in sensitised individuals.
Relevance for Cetyl Esters: Emollients derived from nuts (shea butter, macadamia oil), latex cross-reactive fruits (avocado oil), or highly fragrant plants (rosehip, sea buckthorn) carry higher allergenicity than refined synthetic emollients like squalane or dimethicone.
