PEG-20 Glyceryl Triisostearate

Explained

PEG-20 Glyceryl Triisostearate is a synthetic, oil-loving helper ingredient that does two jobs:

  1. It works as an emulsifer that keeps oil and water mixed into one smooth, stable product.
  2. It's an emollient that softens skin and improves how a product spreads.

This ingredient is made by joining three building blocks: PEG, Isostearic Acid and glycerin. The PEG gives it the oil-and-water blending power.

This ingredient has been found safe for use in cosmetics and broader PEG family testing shows minimal irritation/sensitization. The molecule's large size also means it isn't expected to penetrate skin to any meaningful degree.

Fungal acne note: This ingredient may not be fungal acne safe due to isostearic acid (C18). Isostearic acid falls into the C11-24 range that Malassezia can feed on.
