What it is
Octyldodecanol, a long-chain fatty alcohol, is a clear liquid.
What it does
Octyldodecanol is very used in moisturizers and lotions for two reasons. Its emollient and lubricating properties give skin a soft feel. In addition, it helps to form emulsions and prevents the oil and liquid components of a product’s formula from separating.
It also acts as an anti-foaming agent, helping reduce the tendency of products to produce foam when they are shaken.
It is also rarely used as a solvent and fragrance ingredient.
Octyldodecanol can cause irritations, but it’s rare.
