Safety Information
| Description | Cocamidopropyl betaine is an important zwitterionic surfactant, with a mild detergent action that is also more viscous than the other types of surfactant. |
| Chemical Properties | Cocamidopropyl Betaine (CAB) is an organic compound derived from coconut oil and dimethylaminopropylamine. It is a zwitterion, consisting of both a quaternary ammonium cation and a carboxylate. CAB is available as viscous pale yellow solution that is used as a surfactant in personal care products. |
| Uses | cocamidopropyl betaine is a surfactant derived from a coconut oil salt. It is particularly effective in shampoos, foam baths, shower foams, and other preparations where high, creamy foam and good skin tolerance are desired. |
| Uses | Cocamidopropyl betaine is an amphoteric surfactant, which enjoys increasing popularity among cosmetic chemists because of its low potential for irritation of the skin. It is used especially in shampoos and bath products such as bath and shower gels. Most cases of allergy are caused by shampoos . Thus, Cocamidopropyl betaine is the exception to the rule that allergic reactions arc usually caused by “stay-on” (“leave-on”) cosmetic products. However, Cocamidopropyl betaine may also be an allergen in other cosmetic products such as skin care products and deodorants and in contact lens fluids. |
| Uses | Cocamidopropyl betaine is one of themost common surface-acting agents used incosmetics, including the following: 1. Cosmetics (shampoos, cleansing lotions and gels, detergents, and hair dyes and styling products) 2. Contact lens solutions 3. Antiseptics |
| Definition | Cocamidopropyl betaine, an amphoteric surfactant, is one of the most commonly used surfactants in cosmetics. It is synthesized from three substances: a coca fatty acid, dimethylaminopropylamine, and rnonochloroacetic acid. It is patch tested as a 1% concentration in water. |
| General Description | Cocamidopropyl betaine is a zwitterion, consisting of both a quaternary ammonium cation and a carboxylate. CAPB is used as a medium strength surfactant. Cocamidopropyl betaine, derived from coconut oil, is an amphoteric surfactant widely utilized in an array of products spanning shampoos, body washes, cosmetics, and household cleaners. Functioning as a gentle surfactant, it effectively reduces surface tension and generates a foaming action when combined with water. Furthermore, it exhibits remarkable abilities in stabilizing and emulsifying other ingredients within various formulations. Beyond its practical applications, cocamidopropyl betaine plays a significant role in scientific research. It has been employed to investigate the impact of surfactants on the environment and has contributed to the development of novel surfactants. |
| Contact allergens | Cocamidopropyl betaine is a pseudo-amphoteric zwitteriondetergent derived from long-chain alkylbetaines. It is availablefrom many suppliers under more than 50 trade names(including Tego-betain L7 and Ampholyt JB 130). Exposureoccurs via rinse-off products such as liquid soaps, shampoos,and shower gels, but also via leave-on products (forexample, roll-on deodorant). Occupational sources aremainly in hairdressing. The first synthesis step consists ofthe reaction of coconut fatty acids with 3-dimethylaminopropylamine,giving cocamidopropyl dimethylamine. Thisamido amine is converted into cocamidopropyl betaine byreaction with sodium monochloroacetate. Both dimethylaminopropylamineand cocamidopropyl dimethylamineare thought to be the sensitizers. |
| Synthesis | The synthesis of cocamidopropyl betaine can be divided into many different synthesis processes according to different carbon chain sources. At present, domestic manufacturers generally adopt the synthesis process with cocoacetic acid as the carbon chain source. This process has the advantages of low synthesis difficulty, high product purity, white color and simple synthesis equipment requirements, but the reaction time is long and the synthesis efficiency is low. Foreign manufacturers also use coconut oil as the carbon chain source of the synthetic process, the raw material price of this process is cheap, simple synthetic equipment requirements, but the product color is dark, and contains about 2.2% of glycerol. The synthesis process using methyl cocoate as the carbon chain source has the advantages of low raw material cost, short reaction time, high synthesis efficiency, and the mixture of methanol and N,N-dimethyl-1,3-propanediamine removed from the reaction can be easily reused after distillation and purification. |
