Aminomethyl Propanol

What is Aminomethyl Propanol?

Aminomethyl Propanol is a synthetic aliphatic alcohol amine, chemically known as 2-amino-2-methyl-1-propanol. This clear, colorless liquid with a faint ammonia scent is widely used in cosmetics, particularly in hair care like dyes, permanent waves, and shampoos, as well as skin and nail products. It functions primarily as a pH adjuster by neutralizing acids to elevate pH levels precisely, which is crucial for product efficacy. As a buffering agent, it resists pH fluctuations from environmental factors or ingredient interactions, preserving formulation integrity over time. This role ensures active components remain effective, preservatives work reliably, and the product delivers a balanced sensory experience on skin or hair. Employed at trace levels in both rinse-off and leave-on items, it supports overall product quality without pore-clogging tendencies.
