Coco-glucoside
Common Name(s): Coconut glucoside,apg c8-c16
CAS Number: 68515-73-1
DESCRIPTION
What It Does: Provides gentle, natural-origin cleansing with good foam from mixed coconut chain alkyl glucosides.
Why It's Used: Widely used natural surfactant for green beauty formulations requiring good foam performance with natural-origin and mild credentials.
How It Works: Mixed c8-c16 fatty alcohol chain lengths from coconut provide broader foam stability than single-chain glucosides. non-ionic glucoside headgroup provides mildness. better detergency and rinsing than individual chain-length apgs due to mixed chain distribution.
Typically Found In: Natural shampoos,body washes,facial cleansers

SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.

SCIENTIFIC NOTE
Coco-glucoside's natural chain length distribution (c8-c16) provides synergistic surfactant effects where different chain lengths optimize different properties: shorter chains provide initial foam burst, longer chains provide foam stability and soil removal, creating better overall performance than any single chain length alone.
