About this ingredient
Aminomethyl Propanediol (AMPD) is a synthetic amino alcohol. Used as a pH adjuster in cosmetic formulas to neutralize acidic components (carbomer, acids). Mechanism. A weak base, it raises formula pH when added to acidic compositions. Used to activate carbomers (form gels only at neutral pH) and to neutralize salicylic and other acids. No skin action on its own. Where applied. Carbomer gels (0.1–1%), spray gels, anti-aging serums. An alternative to triethanolamine (TEA) with lower irritation potential and without nitrosamine concerns. Safety. CIR confirmed safety at cosmetic concentrations in 2009. Hypoallergenic, irritation extremely rare. Unlike TEA, does not form carcinogenic nitrosamines in combination with diethanolamine-containing ingredients. Pregnancy and lactation – safe. Acceptable at any stage. Functional role. No standalone skin activity – a formulation aid.
