CAS 79-14-1 corresponds to glycolic acid, which is the smallest alpha hydroxy acid with a molecular formula of C ₂ H ₄ O3 and a molecular weight of 76.05. It is widely used in cosmetic exfoliation, industrial cleaning, and organic synthesis.

Basic Information
-Chinese name: Hydroxyacetic acid (alias: Glycolic acid, Glycolic acid, Hydroxyacetic acid)
-English name: Glycolic acid
-Molecular formula: C ₂ H ₄ O ∝
-Molecular weight: 76.05
-Structural formula: HOCH ₂ COOH
-EINECS number: 201-180-5
-Appearance: The pure product is a colorless and easily hygroscopic crystal; Industrial products are often 70% light yellow liquid with a slight caramel flavor
-Solubility: Highly soluble in water, ethanol, and ether; Insoluble in hydrocarbon solvents

Physicochemical parameters
-Melting point: 75-80 ° C
-Boiling point: approximately 265.6 ° C (atmospheric pressure, some data indicate decomposition)
-Density: Approximately 1.416 g/cm ³ (25 ° C)
-LogP: Approximately -1.05 (Strong hydrophilicity)
-Stability: Stable at room temperature, reacts with strong oxidants and alkalis; High temperature decomposition produces CO and CO ₂

main purpose
1. Cosmetics/Skincare: As a core ingredient of alpha hydroxy acids (AHA), it promotes exfoliation, whitens and lightens spots, and improves skin quality.
2. Industrial cleaning: boiler descaling, metal surface treatment, electroplating additives.
3. Chemical synthesis: preparation of polyglycolic acid (PGA), solvents, dye intermediates, and tanning auxiliaries.
4. Other: soap modification, coating additives, biomarkers for biological metabolism research.

Safety and Protection
-Danger: Highly corrosive and irritating, can cause skin/eye burns; Dust poses a risk of explosion when exposed to fire sources.
-Acute toxicity: Rat oral LD ₅₀ ≈ 1950 mg/kg (low toxicity, but strong local corrosiveness).
-Protective measures: Chemical resistant gloves, goggles, and protective clothing should be worn during operation; Good ventilation; Dilute with a large amount of water during leakage treatment.
