説明
Cocamidopropyl betaine is an important zwitterionic surfactant, with a mild detergent action that is also more viscous than the other types of surfactant.
化学的特性
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.
使用
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.
定義
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.
一般的な説明
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.
接触アレルゲン
Cocamidopropyl betaine is a pseudo-amphoteric zwitterion
detergent derived from long-chain alkylbetaines. It is available
from many suppliers under more than 50 trade names
(including Tego-betain L7 and Ampholyt JB 130). Exposure
occurs via rinse-off products such as liquid soaps, shampoos,
and shower gels, but also via leave-on products (for
example, roll-on deodorant). Occupational sources are
mainly in hairdressing. The first synthesis step consists of
the reaction of coconut fatty acids with 3-dimethylaminopropylamine,
giving cocamidopropyl dimethylamine. This
amido amine is converted into cocamidopropyl betaine by
reaction with sodium monochloroacetate. Both dimethylaminopropylamine
and cocamidopropyl dimethylamine
are thought to be the sensitizers.
