Coactive surfactant

Coactive Surfactant. The secondary surfactant(s) in a detergent formulation. See also Detergent. 

Uses Surfactant, antistat in cosmetics coactive, foam booster/stabilizer, vise. 

Sarcosinate surfactants have been widely used in personal wash, skin care, and hair care formulations as coactives. They are particularly useful in providing a rich, stable lather, especially in the presence of sebum. Lathers produced from other anionic and amphoteric surfactants are remarkably enhanced by the addition of sarcosinates. Maximum foaming and detergency are developed in the pH range 4-8. The adsorption of sarcosinates onto the hair results in manageability and reduced static buildup. Sarcosinate surfactants are easily... 

An extension of the soap-coactive approach has been the production of ultra-mild bars which contain only low levels of soap, with the primary surfactant being a synthetic anionic. The first product of this type was Dove, which contained sodium cocoyl isethio-nate as the primary surfactant More recently modified versions of this formulation have appeared containing milder coactives (e.g., cocoamidopropyl betaine) and an emollient such as stearic acid (32). Such benefits come at a cost to the consumer because these materials are considerably more expensive than simple soaps. Attempts to extend this approach using alternative synthetic anionic surfactants have been less successful. This is mainly due to the poor crystallinity of many synthetic anionic surfactants which even in their anhydrous state are soft pastes as opposed to crystalline solids, making them unsuitable for use at high levels in bar products.
