DECYL ISOSTEARATE

Safety grade: A

This is a lightweight oil derived from natural plant sources that has been chemically modified to make it more stable and easier to use in cosmetics. It's similar to other oils you might find in skincare products, but with a smoother, more refined texture.

This ingredient moisturizes and softens the skin by creating a protective barrier that helps lock in hydration, while also improving the feel and texture of cosmetic formulations.

Graded using: COSING, FDA.
