Cocobetaine is an amphoteric surfactant.
The particular behaviour of amphoterics is related to their zwitterionic character; that means: both anionic and cationic structures are found in one molecule.
Cocobetaine contains coconut oil, which is hydrating.

Cocobetaine's less drying than other surfactants.
Cocobetaine reduces the drying effects of harsher detergents in skin and hair care products.
Cocobetaine produces a thick lather when combined with water.
The lathering action helps loosen the dirt and impurities that you are washing away, so they are easier to rinse off after cleaning.
Cocobetaine is a new type of special amphoteric surfactant, which belongs to the same series as lauramidopropyl betaine, and is a modified derivative of alkyl betaine.
Cocobetaine has the characteristics of temperature resistance, acid and alkali resistance, good salt resistance, wide isoelectric point and strong viscoelasticity, etc.
Cocobetaine is widely used in oil field oil repelling, leather, daily chemical industry and other fields.
As a good viscoelastic surfactant applied to the substrate acidification of oilfield, Cocobetaine can effectively reduce the oil/water interfacial tension and improve the recovery rate of tertiary oil recovery.
Also Cocobetaine can be used as conditioning agent, wetting agent, bactericide, antistatic agent, emulsifier, thickener and in self-steering acid system for carbonate acidification.
Cocobetaine is a mixture of closely related organic compounds derived from coconut oil and dimethylaminopropylamine.
Cocobetaine is available as a viscous pale yellow solution and it is used as a surfactant in personal care products and animal husbandry.
The name reflects that the major part of the molecule, the lauric acid group, is derived from coconut oil.
Cocobetaine to a significant degree has replaced cocamide DEA.
Cocobetaine is a mild amphoteric surfactant derived from coconut oil.
Easily water soluble in a wide pH range.
Contains 36-38% active substances (remaining content is water).
Specific gravity (25°C) 1.4.
Very mild co-surfactant compatible with anionic, non-ionic, cationic surfactants.
Useful also as primary surfactant as Cocobetaine has good cleansing and foam-boosting properties.
Slight thickening and emulsifying properties.
Has good conditioning and antistatic properties.
Cocobetaine, also known as CAPB, is a popular ingredient in home and personal care products.
Cocobetaine is a mild amphoteric surfactant derived from coconut oil and is widely used for its excellent cleansing and foaming properties.
Cocobetaine acts as a versatile surfactant that effectively removes dirt, oils, and impurities from the skin, hair, and various surfaces.
Cocobetaine exhibits good compatibility with other surfactants, making it a valuable ingredient in shampoos, body washes, liquid soaps, and other cleansing formulations.
One of the key advantages of Cocobetaine is its mildness.
Cocobetaine is considered gentle on the skin and hair, making it suitable for use in products targeting sensitive or delicate skin.
Cocobetaine also has excellent foam stability, producing a rich and luxurious lather that enhances the cleansing experience.
Cocobetaine is a surfactant derived from coconut oil.
Cocobetaine also works as a foam enhancer and is used in numerous personal care products like shampoos, conditioners, body washes, mouthwashes, cleansers, etc.
Cocobetaine contains a mixture of fatty acids from coconut oil and propylene glycol.
Cocobetaine is used in personal care products to clean the skin and hair as it lifts and removes oil from them.
Cocobetaine is a milder surfactant than sodium lauryl sulfate (SLS).
Cocobetaine is a surfactant that is used in shampoos, skin cleansers, and other personal care products to create lather and remove dirt.
Cocobetaine has been shown to be effective against bacteria and fungi.
The antimicrobial activity of this surfactant has been tested in vivo on human skin samples, where Cocobetaine was shown to inhibit the formation of skin cancer cells.
Cocobetaine can also be used for wastewater treatment because it has been shown to lyse cells and break down organic matter.
This surfactant also has a matrix effect, meaning Cocobetaine forms a protective layer on the skin that prevents water from evaporating quickly.
The matrix effect is especially useful when using laser ablation, which can cause cell damage if not applied correctly.

Uses
Cocobetaine is used cosmetic and hair compositions of enhanced viscosity and clarity.
Cocobetaine is widely used as a surfactant.
Cocobetaine's usage in personal-care products has grown in recent years due to its relative mildness compared with other surface active compounds.
Cocobetaine is widely used in various cosmetics like shampoos, bath products, and cleansing agents, shower gels, bath foam, liquid soaps, skin care products, hand wash.
Cocobetaine makes products feel creamier.
Cocobetaine's a thickening agent that adds viscosity to products.
Cocobetaine makes them feel richer and makes them less likely to drip while you use them.
Toxicology
Cocobetaine is poorly absorbed from the intestinal tract and through the skin.
Rinsing the skin after 10 minutes of contact reduces the absorption even further.
Following oral or dermal exposure, there is metabolism of the absorbed material, as indicated by the appearance of a more polar compound in the urine and by the liberation of 14CO2.
Production
Despite the name Cocobetaine, the molecule is not synthesized from betaine.
Instead Cocobetaine is produced in a two-step manner, beginning with the reaction of dimethylaminopropylamine (DMAPA) with fatty acids from coconut or palm kernel oil (lauric acid, or its methyl ester, is the main constituent).
The primary amine in DMAPA is more reactive than the tertiary amine, leading to its selective addition to form an amide.
In the second step chloroacetic acid reacts with the remaining tertiary amine to form a quaternary ammonium center (a quaternization reaction).
CH3(CH2)10COOH + H2NCH2CH2CH2N(CH3)2 → CH3(CH2)10CONHCH2CH2CH2N(CH3)2
CH3(CH2)10CONHCH2CH2CH2N(CH3)2 + ClCH2CO2H + NaOH → CH3(CH2)10CONHCH2CH2CH2N+(CH3)2CH2CO2− + NaCl + H2O
