MYRETH-4

Safety grade: A

Myreth-4 is a gentle cleansing agent derived from myristyl alcohol, a fatty alcohol found in nutmeg seed oil. It helps mix oil and water together in products so they stay blended smoothly.

This ingredient acts as an emulsifier to combine oil and water-based ingredients in cosmetic formulas, creating stable, smooth products that don't separate.
