Cocamidopropyl betaine

Chemical properties

Liquid

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.

Characteristics

Cocamidopropyl Betaine (CAB) is perfectly compatible with anionic, cationic and nonionic surfactants, it can still be used as cloudy point inhibitor.
CAB can produce rich and fine foams. Fonnulated with adequate proportion of anionic surfactant, it has significant thickening effect.
CAB has excellent to tolerance to skin, effectively reduce the irritation caused by fatty alcohol sulfate or fatty alcohol ether sulfate in the products.
CAB has antibiotic function, being a good additive in personal sanitary products. CAB has excellent antistatic function, being an ideal conditioning agent.

The Uses of Cocamidopropyl betaine

Cocamidopropyl betaine is a surfactant in liquid soaps, shampoos, hair colorants, shower and bath formulations.

The Uses of Cocamidopropyl betaine

Lonzaine(R) CO is a mild, high foaming, biodegradable cocoamidopropyl betaines. Suggested applications: foam booster for shampoos.

Definition

ChEBI: A mixture of carboxamidopropyl betaines derived from fatty acids of varying chain lengths. The principal component is lauramidopropyl betaine.

What are the applications of Application

Cocamidopropyl betaine is used in cosmetics and personal hygiene products (eg, shampoos, contact lens solutions, toothpaste detergents, makeup removers, bath gels, skin care products, cleansers, liquid soaps, antiseptics, and gynecologic and anal hygiene products).

Hazard

A severe eye irritant.

Flammability and Explosibility

Contact allergens

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.

storage

In the original sealed containers and at temperature between 0°C and 40°C, this product remains stable at least one year. On account during its high salt content the product can have a Corrosive effect during storage in stainless steel tanks.
