Where it fits in your routine
This one works on contact — there is nothing to wait for.
What that covers, and what it does not
Measured on: Surface softness and richness on application, from a waxy fatty-alcohol deposit.
A C18 fatty alcohol, more lipophilic than cetyl, used at 1-5%; like cetyl it softens on contact and the change in surface feel and roughness is instantaneous. Its structural role in creams and balms is an in-bottle function with no timeline, but it does remain on skin as an emollient wax. No trial reports a slower, measured skin outcome for it.
No efficacy-timing trial identified. Ingredient physical chemistry (fatty alcohol emollient/wax); safety literature only.
Plays well with
- fatty acids
- emulsifiers
