GALACTARIC ACID

Safety grade: A

Galactaric acid is a naturally occurring organic compound derived from milk sugar that helps protect skincare and cosmetic products from spoiling. It works by binding to metal ions that could otherwise cause the product to degrade or change color.

This ingredient acts as a chelating agent, binding to trace metals in formulations to prevent oxidation and extend product shelf life while maintaining stability and efficacy.
