What Is Cocamidopropyl Hydroxysultaine?

Cocamidopropyl hydroxysultaine is a surfactant that can act as both an acid and a base.[1,2] It is derived from coconut oil.[3] 

Coconuts grow on the coconut palm tree (cocos nucifera), in lowland tropical and subtropical areas. [4,5] Widely cultivated, the tree can be used to produce food, drinks, fibers, and building materials.[6,7]

What Does Cocamidopropyl Hydroxysultaine Do? 

Cocamidopropyl hydroxysultaine works as a conditioning agent, helping to keep skin and hair soft and supple. It creates a creamy lather with less potential for damage to the outermost layer of skin (the stratum corneum).[8] 

Cocamidopropyl hydroxysultaine can also be used as a foam booster, antistatic agent, and thickener.[9] It is found in hundreds of products, including shampoo, body wash, facial cleansers, hand soap, hair conditioner, and other products.[10]

Is Cocamidopropyl Hydroxysultaine the Same as Cocamidopropyl Betaine?

Though similar, cocamidopropyl hydroxysultaine is different from cocamidopropyl betaine. 

How Cocamidopropyl Hydroxysultaine Is Made

According to the Cosmetic Ingredient Review, a supplier has reported that this ingredient is produced by reacting an inorganic salt with chlorinated epoxide. The resulting intermediate is next reacted with amine. The Cosmetic Ingredient Review reports that the process undergoes quality control, with final adjustments made to yield the standard product.[11]
