PEG-30 Phytosterol
What PEG-30 Phytosterol is & what it does
PEG-30 Phytosterol is a plant sterol (phytosterol) that has been ethoxylated with about 30 units of polyethylene glycol. In cosmetic and sunscreen formulas it acts as a nonionic emulsifier and surfactant, helping blend oil and water phases into a stable product. A notable property is that combining a skin-compatible sterol with a water-loving PEG chain gives it both emulsifying and conditioning character.
What does PEG-30 Phytosterol do in skincare?
PEG-30 Phytosterol acts as a nonionic emulsifier and surfactant, helping blend the oil and water phases of a product into a stable, even formula. Because it is based on a plant sterol, it can also contribute some skin-conditioning character.
Is PEG-30 Phytosterol natural or synthetic?
It is partly plant-derived and partly synthetic. The phytosterol portion comes from plants, but it is then ethoxylated with polyethylene glycol, which is a chemical processing step, so the finished ingredient is best described as a processed derivative.
Is PEG-30 Phytosterol safe?
PEG-based emulsifiers like this are common in cosmetics and are generally regarded as well tolerated for topical use. Sensitivity can vary by person, so patch testing is reasonable. We cannot provide medical advice, so consult a professional for specific concerns.
