Cocoamidopropyl betaine is a mixture of closely related organic compounds derived from coconut oil and dimethylaminopropylamine.

Contents

Uses

  • CAPB is available as a viscous pale yellow solution and it is used as a surfactant in personal care products. The name reflects that the major part of the molecule, the lauric acid group, is derived from coconut oil. Cocamidopropyl betaine to a significant degree has replaced cocamide DEA.

Benefits

  • Cocamidopropyl betaine is a surfactant that is a common ingredient in many liquid skin cleansers. Surfactants allow water to wash away the oil and dirt from your skin by decreasing the surface tension of water and making it easier to wet your face.

Cautions

  • CAPB has been claimed to cause allergic reactions in some users, but a controlled pilot study has found that these cases may represent irritant reactions rather than true allergic reactions. Furthermore, results of human studies have shown that CAPB has a low sensitizing potential if impurities with amidoamine (AA) and dimethylaminopropylamine (DMAPA) are low and tightly controlled.
  • Other studies have concluded that most apparent allergic reactions to CAPB are more likely due to amidoamine. Cocamidopropyl betaine was voted 2004 Allergen of the Year by the American Contact Dermatitis Society.
