PEG-10 HYDROGENATED CASTOR OIL TRIISOSTEARATE

Safety grade: A

This ingredient is a modified form of castor oil that has been processed to help oil and water mix together smoothly in cosmetic products. It acts like a bridge between ingredients that normally don't blend well, similar to how soap helps oil wash away with water.

This ingredient helps blend incompatible ingredients together and controls how thick or thin a product feels, ensuring a smooth, stable texture in lotions, creams, and other cosmetics.

Graded using: COSING.
