Questions And Answer

• Description

  Cocamidopropyl betaine (CAPB) is an amphoteric surfactant. The particular behaviour of amphoterics is related to their zwitterionic character; that means: both anionic and cationic structures are found in one molecule.;

• Uses

  Cocamidopropyl betaine is widely used as a surfactant. The usage of cocamidopropyl betaine in personal-care products has grown in recent years due to its relative mildness compared with other surface active compounds. Cocamidopropyl betaine is widely used in various cosmetics like shampoos, bath products, and cleansing agents, shower gels, bath foam, liquid soaps, skin care products, hand wash detergents. Uses in household cleaning products, the scope of HERA, include laundry detergents, hand dishwashing liquids, and hard surface cleaners.;

• Health Hazard

  Skin irritation: According to current OECD guideline, cocamidopropyl betaine (about 30% aqueous solution and nearly 80% spray-dried substance) is not a skin irritant. In human studies up to 3 % solutions were weakly irritating. Impurities like amidoamine may contribute to the irritation reaction. The irritating properties of sodium lauryl sulphate formulations could be significantly reduced by the addition of cocamidopropyl betaine.
  Eye irritation: The concentrated and the 25 - 30 % active cocamidopropyl betaine is an irreversible eye irritant. The 15 % concentrations were irritating to highly irritating. At and below 10% active dilution studies show a mild to moderate and reversible eye irritating potential of cocamidopropyl betaine. ;

• Toxicology

  The acute oral and dermal toxicity of cocamidopropyl betaine 30 – 35.5 % active solution in rats is low. The LD₅₀ (dermal) is > 2000 mg/kg bw (which was the highest dose applied), LD₅₀ (oral) is ≥ 4900 mg/kg bw. There were no clinical signs reported after acute dermal exposure; after oral exposure to high doses, decreased motor activity, diarrhea, and ataxia as well as signs of gastrointestinal irritation were found. ;
