Our take
Is PEG-40 Hydrogenated Castor Oil a Good Ingredient?
Rated Good due to strong, consistent solubilizing performance and mild cleansing action supported by extensive cosmetic use. It can provoke slight eye or skin irritation in sensitive individuals, particularly at higher concentrations or in leave-on formats, which is what keeps it from a higher rating.
What it does
Skin Benefits
Helps incorporate fragrance and plant oils into clear liquids for a uniform look. Supports gentle cleansing and easier rinse-off in wash-off products.
Where you'll find it

Before you use it
Safety
Generally safe for most users; temporary eye or skin irritation is possible, especially with higher loads or prolonged contact. Rinse-off products tend to be milder; consider patch testing for leave-ons on sensitive skin.
