GENERAL DESCRIPTION AND APPLICATIONS
Sarcosine , also known as methyl-glycoccoll, is an amino acid intermediate naturally found in the metabolism of choline to glycine. Commercially, synthetic sarcosine is obtained by the reaction of methylamine with monochloracetic acid. It is adeliquescent crystal; having sweet taste; dissolve in water, slightly soluble in alcohol; decomposes at 208 C. It is used in manufacturing biodegradable surfactants and toothpastes as well as in biological applications. Sarcosinate Surfactants are mild, biodegradable anionic surfactants derived from fatty acids and sarcosine (amino acid). These compounds fovor lather building and resistance to sebum delathering in cleaners, polymers, industrial chemicals, petroleum and lubricant products. Sodium Cocoyl Sarcosinate is used as a foaming and cleansing agent for shampoo, shaving foams and foam washes. It is used as a corrosion inhibitor and in formulating textile treatment agents.

GENERAL DESCRIPTION OF IONIC SURFACTANTS

Ionic surfactants which contain hydrophobic hydrocarbon group connected with one or several hydrophilic groups dissociate into a positively charged cation and a negatively charged anion in an aqueous solution. If the head is negatively charged to carry the surface active properties, it is called anionic surfactant, whereas a positively charged head is the carrier of the surface active properties in cationic surfactants. Typically cationic surfactants are based on the nitrogen atom carrying the cationic charge such as amine and quaternary ammonium product.

Cationic surfactant is considered to be poor cleaners but it contributes to the fabric softening, the disinfecting properties, and the grease-water interfacial tension reducing. Cationic surfactants include quaternary ammonium compounds, amines (primary, secondary, tertiary, diamines, polyamines, amine salts), imidazoline compounds, betaine compounds, and esterquats.

Anionic surfactant is the widely used type of surface active agent for laundry detergents, liquid cleaners and shampoos due to excellent cleaning properties particularly effective at oily soil cleaning and oil/clay soil suspension. Anionic surfactants are deactivated in many hard water. To prevent deactivation, builders should be dosed. Anionic surfactant is used as a emulsifier in cosmetics, tooth paste, cream, shampoo, and acrylic binder. Common soap is an anionic surfactant. Carboxylate, sulfate, sulfonate and phosphate are the polar groups in anionic surfactants. Anionic surfactants include alkyl benzene sulfonate, fatty acid salts, sodium lauryl sulfate, alkyl sulfate salts, sodium lauryl ether sulfate, alpha-olefin sulfonates, phosphate esters, sulphosuccinates, alkyl phenol ether sulfates, and isethionates.
