PEG-30 Stearate
What is PEG-30 Stearate?
PEG-30 Stearate is a polyethylene glycol ester, primarily used in cosmetics and personal care products. It's created by the esterification of stearic acid with polyethylene glycol, resulting in a substance that helps emulsify and stabilize formulations.
In products, PEG-30 Stearate is used to help mix oil and water, providing stability to a final product such as lotions and creams. This emulsification capability means it ensures a product retains a uniform texture and effective consistency.
For consumers, it's important to note that while PEG compounds are generally considered safe, they can sometimes cause irritation, particularly in those with sensitive skin or when products are used on broken skin.
Commonly found in: lotions, creams, moisturizers, sunscreens, hair conditioners

Scout's take
Polyethylene glycol-derived emulsifier. Can be contaminated with 1,4-dioxane depending on manufacturer purification. Galderma's spec is reportedly low-1,4-dioxane.
