Common Name(s): Peg-30 hydrogenated castor oil triisostearate,peg-30 hco triisostearate (triple esterified hco),polyoxyethylene-30 hydrogenated castor oil triisostearate (triple esterified hco)

DESCRIPTION

What It Does: Helps oil and water blend and can dissolve oily ingredients into clear water-based products.

Why It's Used: Hlb ~12–14 from peg-30 modification; hydrogenated castor oil provides stable ricinoleic-based core with triisostearate (triple esterified hco) modification.

How It Works: Peg-30 units give hlb ~12–14; hydrogenated castor oil core (12-hydroxystearic acid glycerides) provides oil-phase anchoring; triisostearate (triple esterified hco).

Typically Found In: O/w emulsions,clear formulations,oil solubilizers,fragrance solubilizers
