PEG-5 Rapeseed Sterol

PEG-5 Rapeseed Sterol is a surfactant and emulsifier derived from rapeseed oil. It is created by attaching polyethylene glycol (PEG) chains to rapeseed sterols, which are naturally occurring compounds found in the rapeseed plant. This modification makes the ingredient water-soluble and able to function as a cleansing agent.In skincare formulations, it serves primarily to remove oils and impurities from the skin surface and to help blend water and oil-based ingredients together so they remain stable in a product.

As a surfactant, PEG-5 Rapeseed Sterol works by having one end that attracts oils and another that attracts water. This allows it to surround and suspend oils and dirt so they can be rinsed away during cleansing.In formulations, it also acts as an emulsifier, meaning it helps oil and water phases stay mixed together rather than separating, which extends shelf life and ensures consistent texture.

This ingredient is typically used in cleansing products or other formulations where emulsification is needed, rather than in serums or treatment products. Use as directed on the product label. If you are prone to fungal acne or have known sensitivities to surfactants, patch test first or consult a dermatologist, as some individuals may find certain surfactants trigger breakouts.

PEG-5 Rapeseed Sterol is generally well-tolerated on most skin types. Some acne-prone or fungal-acne-sensitive individuals may wish to avoid products containing multiple surfactants; patch testing is recommended if you have a history of reaction to cleansing agents.
