Glyoxylic Acid
What is Glyoxylic Acid?
Glyoxylic acid, chemically 2-oxoacetic acid (C2H2O3), is a small-molecule organic compound typically handled as a hydrate in aqueous environments. Synthetically produced from glycolic acid oxidation or glyoxal hydrolysis, it appears as a colorless liquid with a faint odor. In cosmetics, it falls into functional categories like hair care and general formulation aids. Known for its role in semi-permanent hair straightening by penetrating hair shafts and promoting temporary cross-linking via hydrogen bonds with keratin, it excels as a pH adjuster and buffering agent. These functions involve donating or accepting protons to shift or hold pH within desired ranges, ensuring ingredient compatibility, preventing degradation, bolstering antimicrobial defenses, and promoting skin-friendly application without harshness.
