Common Name(s): Polyglyceryl-3 myristate,polyglyceryl-3 myristic acid (c14) ester,polyglycerol-3 myristic acid (c14)

DESCRIPTION

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

Why It's Used: Polyglyceryl-3 head provides hydrophilicity (hlb ~5–7); myristic acid (c14) tail provides oil-phase affinity; natural-origin compatible.

How It Works: Polyglycerol-3 backbone with myristic acid (c14) ester tail; hlb ~5–7; polyglyceryl esters are widely used natural-origin emulsifiers suitable for organic cosmetic certification.
