PEG-20 Hydrogenated Castor Oil

PEG-20 Hydrogenated Castor Oil is a synthetic ingredient derived from castor oil that has been chemically modified through hydrogenation and polyethylene glycol (PEG) treatment. This process transforms the oil into a soluble compound with strong emulsifying properties.In skincare formulations, it functions as an emulsifier and surfactant—ingredients that allow water and oil-based components to mix together smoothly. This helps create stable, homogeneous textures in serums, creams, and cleansing products.

PEG-20 Hydrogenated Castor Oil has a molecular structure with both water-loving (hydrophilic) and oil-loving (lipophilic) regions. This dual nature allows it to sit at the boundary between water and oil phases, holding them together in a stable mixture rather than allowing them to separate.As a mild surfactant, it can also gently bind to oils on the skin surface, helping them lift away during cleansing.

This ingredient is typically incorporated into formulations by manufacturers rather than used as a standalone product. Look for it in the ingredient list of cleansers, serums, and emulsions. It works effectively across different product types and doesn't require specific application techniques on your part.

PEG-20 Hydrogenated Castor Oil is generally well-tolerated in skincare. Some individuals with very reactive or sensitised skin may find products containing PEG compounds slightly irritating, though this is uncommon.
