hydroxyacetic acid
C2Technical/Scientific
Definition
Meaning
A simple organic acid with the chemical formula C₂H₄O₃, containing both a hydroxyl (-OH) and a carboxylic acid (-COOH) group.
A colourless, crystalline, water-soluble compound used in various industrial processes, including chemical cleaning, textile processing, and as a precursor in organic synthesis. It is also known as glycolic acid and occurs naturally in some plants and sugar cane.
Linguistics
Semantic Notes
The term is primarily used in chemistry, biochemistry, and industrial contexts. 'Hydroxyacetic acid' is the systematic IUPAC name, while 'glycolic acid' is the more common trivial name in commercial and cosmetic contexts.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or spelling differences. Both regions use the systematic name 'hydroxyacetic acid' and the trivial name 'glycolic acid' interchangeably in technical literature.
Connotations
None beyond the scientific/technical domain.
Frequency
The term 'glycolic acid' is significantly more frequent in commercial, cosmetic, and general scientific discourse in both regions. 'Hydroxyacetic acid' is more common in formal chemical nomenclature and specific industrial contexts.

Usage
Context Usage
Business
Used in the cosmetics industry (e.g., 'The new serum features a 10% hydroxyacetic acid formulation for exfoliation.') and in industrial chemical supply.
Academic
Common in chemistry, biochemistry, and materials science papers discussing organic synthesis, acid properties, or skin physiology.
Everyday
Virtually never used in everyday conversation. A layperson might encounter 'glycolic acid' on a cosmetic product label.
Technical
The standard term in chemical patents, industrial process descriptions, and safety data sheets (SDS).

Examples
By CEFR Level
- This cream has an acid in it for smooth skin. (Glycolic acid is a simpler term used here.)
- Some skin peels use glycolic acid, which is also called hydroxyacetic acid.
- Hydroxyacetic acid, a common alpha-hydroxy acid, is valued in cosmetics for its exfoliating properties.
- The industrial synthesis of hydroxyacetic acid typically involves the reaction of formaldehyde with carbon monoxide and water under high pressure.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'уксусная кислота' (acetic acid). The correct translation is 'гидроксиуксусная кислота' or, more commonly, 'гликолевая кислота'.
Common Mistakes
- Misspelling as 'hydroxyacetic acid'.
- Confusing it with 'acetic acid' (vinegar).
- Incorrectly capitalising it as a proper noun.

FAQ
Frequently Asked Questions
In concentrated forms, it is corrosive and can cause severe skin and eye damage. In diluted, controlled formulations (like in cosmetics), it is generally safe for its intended use.
They are the same chemical compound. 'Hydroxyacetic acid' is the formal, systematic chemical name. 'Glycolic acid' is the common, trivial name used in industry and commerce.
It can be synthesized industrially from formaldehyde, carbon monoxide, and water. It also occurs naturally in sugar cane, beets, and some fruits.
It is a small molecule that can penetrate skin, helping to break down bonds between dead skin cells (exfoliation), which can improve skin texture and appearance.
