Common Name(s): Peg-60 castor oil isostearate,peg-60 castor oil isostearate (dual-modified) ester,polyethylene glycol-60 castor oil isostearate (dual-modified) 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 ~15–16 o/w emulsification and skin conditioning; the castor oil isostearate (dual-modified) chain provides natural affinity with skin lipids.

How It Works: 60 eo units give hlb ~15–16; castor oil isostearate (dual-modified) tail provides oil-phase anchoring and skin conditioning; nonionic character enables broad ph compatibility and electrolyte tolerance.
