Common Name(s): Peg-7 stearate,peg-7 stearic acid ester,polyethylene glycol-7 stearic acid ester

DESCRIPTION

What It Does: Helps oil and water blend together in creams and lotions while conditioning and moisturizing skin.

Why It's Used: Selected for hlb ~7–9 o/w emulsification and skin conditioning; the stearic acid chain provides natural affinity with skin lipids.

How It Works: 7 eo units give hlb ~7–9; stearic acid tail provides oil-phase anchoring and skin conditioning; nonionic character enables broad ph compatibility and electrolyte tolerance.

Typically Found In: O/w emulsions,creams,lotions,skin conditioning products
