What it is
This ingredient is the ester of decaglycerin (polyglycerol-10) with myristic acid, producing a mild, nonionic, PEG-free emulsifier. It helps blend oil and water phases into stable emulsions and can also act as a gentle cleansing or solubilizing aid. In sunscreens it supports a stable, lightweight emulsion while contributing a soft skin feel.
Safety & warnings
Polyglyceryl esters are valued for being mild and are generally well tolerated, often chosen for sensitive-skin and PEG-free formulations. They are not fragrance allergens and have a low irritation profile.
Origin & sourcing
Synthetic; made by esterifying polyglycerol-10 (derived from glycerin) with myristic acid, a common fatty acid.
Questions everyone asks
What does polyglyceryl-10 myristate do?
It is a mild nonionic emulsifier that helps oil and water mix into a stable emulsion and conditions the skin.
Is it a PEG-based ingredient?
No. It is built on polyglycerol rather than polyethylene glycol, so it is often used in PEG-free formulas.
