This one works on contact — there is nothing to wait for.
What that covers, and what it does not
Measured on: Surface softness and cushion on application, from a waxy fatty-alcohol deposit.
A C16 fatty alcohol used at 1-5%, deposited from the oil phase; the emollient softening and reduced surface roughness are present as soon as the product is spread. Part of its value is genuinely in the bottle (viscosity building, emulsion stabilisation), which is not a skin outcome, but unlike a preservative it also stays on skin and softens it. No published trial times any longer-term change for cetyl alcohol.
No efficacy-timing trial identified. Ingredient physical chemistry (fatty alcohol emollient deposit); long history of safe cosmetic use documented in safety reviews only.

- fatty acids
- emulsifiers
