Peg-30 Glyceryl Isostearate
PEG-30 Glyceryl Isostearate is a PEG-modified ester of glycerin and isostearic acid used in cosmetic formulations as a nonionic emulsifier and solubilizer. It stabilizes oil-in-water systems, improves spreadability, and helps disperse small oil loads in aqueous formulas.

Our take
Is Peg-30 Glyceryl Isostearate a Good Ingredient?
Rated Good because it reliably stabilizes oil-in-water emulsions and improves slip without adding heaviness, with a long record of use and generally low irritation. As a PEG-derived emulsifier, it may cause mild stinging or redness on very sensitive or compromised skin, which is what keeps it from a higher tier.

Skin Benefits

Where you'll find it

Often included in moisturizers, sunscreens, and lotions to keep textures homogeneous. Also used in light creams and serums to improve the overall sensorial experience.
Before you use it
Safety
Generally considered low risk and well tolerated in leave-on and rinse-off products. Mild irritation can occur for very sensitive skin, especially on broken or compromised barriers. Patch testing is prudent if you're reactive.
