Detergents amphoteric

Amphoteric Detergents. These surfactants, also known as ampholytics, have both cationic and anionic charged groups ki thek composition. The cationic groups are usually amino or quaternary forms while the anionic sites consist of carboxylates, sulfates, or sulfonates. Amphoterics have compatibihty with anionics, nonionics, and cationics. The pH of the surfactant solution determines the charge exhibited by the amphoteric under alkaline conditions it behaves anionically while ki an acidic condition it has a cationic behavior. Most amphoterics are derivatives of imidazoline or betaine. Sodium lauroamphoacetate [68647-44-9] has been recommended for use ki non-eye stinging shampoos (12). Combkiations of amphoterics with cationics have provided the basis for conditioning shampoos (13). 

Baby Shampoos. These shampoos, specifically marketed for small children, feature a non-eye stinging quaHty. The majority of the products in this category are based on an amphoteric detergent system a system combining the use of an imidazoline amphoteric with an ethoxylated nonionic surfactant has been successfiiUy marketed (15,16). The sulfosuccinates also have been suggested for baby shampoo preparation because of thek mildness... 

Cocamidopropyl betaine is an amphoteric detergent, a detergent that can act as an acid or a base. It does not irritate the skin or mucous membranes. It is used to thicken shampoos, and to reduce the irritation that would result if only more irritating detergents were used. It has antibiotic effects, and is used in personal sanitary products. It also has antistatic properties, making it an effective conditioning agent in shampoos. 

In addition to the soaps and fatty acids, some bars contain cocamidopropyl betaine, a mild amphoteric detergent that is added to control irritation without decreasing suds or cleaning power, and benzine sulfonate detergents such as sodium dode-cylbenzinesulfonate. Other detergents, such as sodium isethion-ate and sodium cocoyl isethionate, are also common. 

Sodium isethionate is an amphoteric detergent used in detergent bar soaps. It makes a dense lather in addition to the lather made by the soap. It is nondrying and mild on the skin. It works equally well in soft or hard water. It is also an antistatic agent in shampoos. 

Sodium cocoyl isethionate is a related amphoteric detergent used in mild bath soaps, toothpastes, and baby soaps.

The soaps and syndets we have mentioned so far are anionic detergents they have a lipophilic chain with a negatively charged polar end. But there are also cationic, neutral, and even amphoteric detergents, in which the polar portion of the molecule is positive, neutral, or dipolar, respectively. Here are some examples ...

Ramirez and Vishnupad [70] reported that they were able to produce post-foaming, clear gels using Pluronic and Tetronic polyols in conjunction with volatile hydrocarbons in anionic or amphoteric detergent formulations. Unlike earlier formulations, these products were not self-foaming when enclosed in containers and could easily withstand transportation and storage. Pluronic...
