PEG-40 Hydrogenated Castor Oil
What is PEG-40 Hydrogenated Castor Oil?
PEG-40 Hydrogenated Castor Oil is a synthetic compound derived from castor oil and polyethylene glycol. It's created by modifying castor oil with hydrogenation and attaching polyethylene glycol chains, which helps it mix better with water.
This ingredient is used primarily as an emulsifier and surfactant in skin care products, allowing water and oil-based ingredients to blend smoothly. Some studies suggest it may cause skin irritation in sensitive individuals, but generally it's considered safe for topical use.
When you see PEG-40 Hydrogenated Castor Oil on a label, it indicates an intention to create a stable, homogeneous product. This ingredient also helps improve texture and feel in creams and lotions.
