Aminomethyl Propanediol

What is Aminomethyl Propanediol?

Aminomethyl propanediol is a synthetic organic compound, chemically known as 2-amino-2-methylpropane-1,3-diol, belonging to the class of amino alcohols. It features a propane backbone with hydroxyl groups and an amino substituent, making it water-soluble and versatile for cosmetic formulations. Primarily found in skincare, hair care, and makeup products, it serves in the category of functional additives. In products, it functions by donating or accepting protons to adjust pH levels precisely, ensuring compatibility among ingredients and optimal performance. As a buffering agent, it resists pH fluctuations from environmental factors or ingredient interactions, promoting long-term stability. Additionally, it contributes to fragrance profiles by masking undesirable odors or adding subtle scent notes, enhancing the overall user experience without dominating the aroma.
