Cocamidopropyl Betaine - 61789-40-0

Key Functions: Cosmetics & Personal Care

It is made from the reaction of coconut fatty acids and 3,3 dimethylaminopropylamine (DMAPA) which yields cocamidopropyl dimethylamine, and then reacted with sodium monochloracetate to derive cocamidopropyl betaine (CIR 2012). Thus, it contains a mixture of coconut oil-derived fatty acids of varying alkyl chain lengths (C8 to C18) connected through amidopropyl linkage to a positively charged, dimethylated nitrogen, and is amphoteric, having both positive and negative charges. Concentrations of cocamidopropyl betaine are expressed as percent activity, referring to the percent solids minus the percent of sodium chloride in the formulation. Cocamidopropyl betaine is a high production volume (HPV) chemical with a reported annual production of 10,000,000 – 50,000,000 lbs. in the United States (PubChem 2021) and 10-100 tons in Europe (ECHA 2021). It has numerous applications in industrial and personal care products, including antistatic, cleansing, foam boosting, hair conditioning, surfactant, and viscosity controlling agent (EC 2021; CIR 2017, U.S. EPA 2010, ECB 2000)
