Sphinganine
What is Sphinganine?
Sphinganine is a naturally occurring sphingoid base, chemically known as (2S,3R)-2-aminooctadecane-1,3-diol, found in the human skin's stratum corneum as part of sphingolipids. These lipids form a key component of the skin barrier. In cosmetics, it belongs to the skin and hair conditioning category, appearing in moisturizers, serums, creams, and shampoos. It works by embedding into the skin's lipid layers, promoting suppleness and hydration retention much like endogenous ceramide precursors. For hair, it coats strands to minimize friction, enhancing smoothness and shine without residue buildup. Derived synthetically or from natural sources to match skin's composition, it supports overall product emollience without altering texture significantly. Typical use levels ensure compatibility in rinse-off and leave-on formulations.
