Overview
Aminomethylpropanol (CAS 124-68-5 ), commercially known as AMP, is a multifunctional amino alcohol used across personal care, coatings, and pharmaceutical manufacturing. It functions primarily as a pH adjuster and neutralizing agent.
This versatile chemical enables formulators to control alkalinity in aqueous systems with precision. In personal care formulations, including lotions and shampoos, AMP neutralizes carbomer and acrylate polymers to build viscosity.
It is also essential for stabilizing emulsions in various cosmetic products. Coatings manufacturers use it to neutralize waterborne resins, improving dispersion stability and film formation in architectural and industrial paints.
Pharmaceutical and topical formulations rely on AMP to buffer active ingredients and adjust final product pH within required specification ranges. Its mild biocidal contribution also supports preservation efficacy in cosmetic systems.
This is particularly useful where broad-spectrum protection is required for long-term stability. Aminomethylpropanol is supplied as a clear liquid, typically at 95% and 100% concentrations for industrial use.
Technical and cosmetic grades are the most commonly traded forms, with cosmetic-grade material meeting purity requirements for personal care applications. Bulk supply is available in drums and IBC containers.
Smaller packaging options are also available for laboratory and specialty use. The material is handled according to strict safety protocols to ensure quality and consistency across all manufacturing batches.
