Acrylic acid or propenoic acid is the simplest unsaturated monocarboxylic acid with the formula: CH2=CH-COOH. The acrylic acid is a colourless, water-soluble liquid with a slightly pungent, vinegar-like odour. Its salts and esters (acrylic acid esters) are called acrylates.

Acrylic acid is a comonomer for the production of special polymers (polyacrylic acid derivatives). It tends to polymerize very quickly(polyacrylic acid). In the cosmetic/hygienic field, the main use of acrylic acid is in superabsorbents (e.g. diapers, sanitary towels, dressing materials) where the acrylic acid can absorb up to a thousand times its volume.

The substance is harmful if swallowed (stomach irritation, nausea, vomiting and diarrhoea). It can be absorbed through skin contact. Inhaled acrylic acid can lead to toxic pulmonary oedema.
