Common Name(s): Hexyldecyloctadecanol,branched c34 fatty alcohol,2-hexyl-1-decyl-1-octadecanol
DESCRIPTION
What It Does: Provides ultra-rich waxy emolliency and thick texture in luxury skin and lip products.
Why It's Used: A branched very long chain fatty alcohol (c34) with improved cold stability versus linear c34 equivalents; provides structured waxy emolliency in premium cosmetic formulations.
How It Works: Branched c34 fatty alcohol structure reduces crystallinity versus linear c34; provides structured viscosity and waxy emolliency; similar to dodecyltetradecanol but higher mw providing more substantive conditioning.
