Isopropanolamine
What is Isopropanolamine?
Isopropanolamine is a synthetic amino alcohol compound, chemically 2-aminopropan-1-ol, derived from propylene oxide and ammonia. This clear, viscous liquid has alkaline properties and belongs to the alkanolamine family. In cosmetics, particularly skincare cleansers, lotions, and hair products, it serves as a key functional ingredient for pH regulation. It works by neutralizing acids within the formula, precisely raising pH to ideal levels that optimize active ingredient solubility, enhance preservative activity, and prevent microbial growth. As a buffering agent, it resists pH changes from environmental factors or ingredient interactions, ensuring long-term product stability. Used at trace amounts, it integrates seamlessly without altering texture or scent, contributing to gentle, effective topical applications across various product types.
