PEG-10 Phytosterol description

PEG-10 phytosterol is a blend of synthetic humectant and solvent PEG-10 with natural skin-conditioning plant sterols from rapeseed (canola) or soy. This ingredient is used in skin care as a cleansing agent/emulsifier and plays a role in enhancing the overall texture of a formula. PEG-10 phytosterol also goes by the name PEG-10 soy sterol or PEG-10 rapeseed sterol, depending on how it’s sourced. While this ingredient is most commonly used for its functions mentioned above, research shows soy phytosterols in particular can help rejuvenate ageing skin by keeping it pliant and supple—a nice side benefit to have! As a class of ingredients, plant-based phytosterols and PEG compounds are generally recognised as safe for use in cosmetic products.
