Aminomethyl Propanol description

Aminomethyl propanol is a synthetic ingredient used in cosmetics as a pH adjuster. It is considered safe as currently used in amounts of 2% or less in cosmetic formulas. Aminomethyl propanol can penetrate skin’s uppermost layers, but does not go further, meaning it does not get into the body. It is believed to aid the penetration of other skin care ingredients which in some circumstances (such as exfoliating acids) can make them more effective while at the same time keeping their efficacious pH range stable. Aminomethyl propanol can be found in all kinds of beauty products from serums and lotions to hair care formulations and dyes, and so on.
