Aminomethyl Propanol
Ingredient Info
Aminomethyl Propanol (AMP) is a pH buffer and preservative used in skincare formulations to maintain product stability and prevent microbial growth. It helps keep products at a safe pH level while extending shelf life.
Benefits
- Helps preserve product and prevent bacterial contamination
- Balances pH to prevent irritation
- Allows brands to reduce reliance on traditional preservatives
Potential concerns
- May interact with amino acids naturally present in skin (taurine), potentially affecting biological function—though significance in topical skincare remains unclear
- Can cause contact dermatitis or irritation in sensitive individuals
- Limited safety data for use in products for infants and very sensitive skin
Science: Recent research (2024) suggests AMP forms hydrogen bonds with taurine, an important amino acid in the body, which could affect its biological functions—though this was studied in controlled laboratory conditions and the relevance to topical skincare exposure is not yet established. AMP is increasingly used as a preservative alternative in cosmetics, including infant formulations, but dermatologists note it may pose irritation risks for sensitive populations.
