Polyglyceryl-20 Octadecabehenate/Hydroxystearate

POL

9/10

Concern level

High concern

A high-molecular-weight polyglyceryl ester used mainly as an oil-phase thickener, texture modifier, and emulsifier/structurant. It helps create balm-like, glossy, cushiony, and more stable oil-based or emulsified systems, and is commonly positioned as a rheology modifier rather than a skin-treatment active.

Risks & Warnings

Low inherent risk in cosmetic use. Potential issues are mostly formulation-related: an under-emulsified or poorly dispersed system may feel waxy or heavy, and any fatty-ester material can be problematic for a small subset of acne-prone users in very rich formulas. No specific pregnancy-related concerns are established. ([taiyointernational.com](https://www.taiyointernational.com/wp-content/uploads/2020/08/TAISET-OG-C_Product-information.pdf))
