PEG-8 Glyceryl Isostearate

PEG-8 Glyceryl Isostearate is a synthetic polymer derived from glycerin and isostearic acid, modified with polyethylene glycol (PEG). It functions as both an emollient and emulsifying agent in skincare formulations.In products, it helps bind water and oil components together, creating stable, uniform textures. It also deposits a light conditioning film on the skin surface, contributing to smoothness and slip.

PEG-8 Glyceryl Isostearate works by positioning itself at the boundary between water and oil, with one end attracted to each. This allows the ingredient to hold disparate components in suspension, preventing creams and lotions from separating over time.On the skin, it forms a thin occlusive layer that reduces transepidermal water loss and imparts a smooth, conditioned feel without blocking pores excessively.

This ingredient is typically used as part of a complete formulation rather than applied alone. Products containing it can be used daily as part of your regular skincare routine. Apply to clean skin and layer with serums or treatments as needed. No special precautions are required for timing or frequency.

PEG-8 Glyceryl Isostearate is generally well-tolerated and considered safe for topical use. Some individuals with sensitivities to polyethylene glycol ingredients may wish to patch-test first.
