PEG-58 HYDROGENATED CASTOR OIL ISOSTEARATE

Safety grade: A

This is a chemically modified version of castor oil that helps mix together ingredients that normally don't blend well, like oil and water. It also helps adjust how thick or runny a product feels when you apply it.

This ingredient acts as an emulsifier to blend oil and water-based components together smoothly, while also controlling the thickness and texture of the final product.

Graded using: COSING.
