Common Name(s): Pumpkin seed oil polyglyceryl-4 esters,polyglyceryl ester o/w emulsifier,cosmos natural emulsifier

CAS Number: N/a

DESCRIPTION

What It Does: Provides o/w emulsification for light textures in certified natural formulations without peg chemistry.

Why It's Used: Cosmos-standard replacement for peg emulsifiers — polyglyceryl esters deliver equivalent emulsification performance from renewable glycerol + vegetable fatty acids.

How It Works: Polyglyceryl chain length controls hlb: pg-2/pg-3 poly-esters (hlb 3–6) → co-emulsifier; pg-6/pg-10 mono-esters (hlb 8–14) → o/w emulsification. cosmos accepts from food-grade vegetable glycerol and natural fatty acids.

Typically Found In: O/w lotions,natural serums,cosmos products
