Are PEGs safe in skincare?

PEGs are generally considered safe for cosmetic use in the concentrations typically found in products. Concerns about contamination with harmful substances like 1,4-dioxane are addressed through purification processes.

What is the purpose of PEG in cosmetics?

PEGs serve multiple functions, including acting as emulsifiers to blend ingredients, humectants to draw moisture to the skin, and solvents to dissolve other components, thereby improving product texture and stability.

PEG

PEG, or Polyethylene Glycol, refers to a family of synthetic polymers used in cosmetics for various purposes. Depending on its molecular weight, it can function as an emulsifier, helping oil and water mix, a humectant to attract moisture, or a solvent. Its primary role is to improve product texture and stability.
