Lactic Acid

Lactic Acid Material Introduction

Lactic acid, also known as hydroxypropionic acid, is a carboxylic acid with CAS number 79-33-4 (L), chemical formula:C₃H₆O₃, and molecular weight 90.08. It appears as a colorless clear or slightly yellow viscous liquid with no distinct odor or a characteristic mild odor, fully miscible with water. High-purity lactic acid tends to crystallize at certain concentrations.

Lactic acid characteristics

Good Biocompatibility

Naturally mild acidic taste, water-soluble

Good antimicrobial properties, pH adjustability

Polylactic acid (PLA) has good biodegradability
