Detergency antiredeposition agents

Carboxymethyl)inulin acts as a polyelectrolyte that can be used as a dispersing agent or metal ion carrier. Carboxymethyl cellulose, for instance, is used as an antiredeposition agent in detergents, in the oil, paper, textile, and mining industries, and as a thickener in foods and drug preparations. Hundreds of thousands of tons of the latter are used per year. 

These amino acid anhydrides are usuaiiy made with phosgene. The use of dimethyi carbonate shouid be tested in the preparation of the monomers. Poiyaspartic acid can be made by heating aspartic acid without soivent to form a polysuccinimide which is then hydrolyzed (12.34).186 It can also be made directly from maleic anhydride and ammonia. It promises to be useful as a scale inhibitor in water, an antiredeposition agent in detergents, and such. Gamma-irradiation converts it to a biodegradable superabsorbent material that takes up 3400 g water per gram of dry polymer.187 (Most superabsorbent polymers are based on acrylamide, a neurotoxin.)...

Syndet bars consist of similar ingredients as powdered detergents. Surfactants, builders, bright-eners, antiredeposition agents, and perfumes are some of the rntgor componeuts. 

Antiredeposition Agent. A component in a detergent formulation that acts to help prevent redeposition of dispersed dirt or grease. Example carboxymethylcellulose. See also reference [4], Detergent. 

Antiredeposition agents are compounds added to laundry detergents to prevent the redeposition of soil on clothes. The most common examples are cellulose ethers or esters.

As an antiredeposition agent, it is widely used in detergents to prevent oil droplets from being redeposited on the fabric, once removed by the surfactant. In this case, ionic repulsion is called into play at the colloidal level. 

An important part of the water hardness is now eliminated by the sodium carbonate which, by becoming calcium carbonate, starts precipitating. The polymer is then called to perform its classical function of crystal inhibitor and antiredeposition agent, a function which still increases with the polymer level because we have a large excess of carbonate ions compared with the calcium counterions 800 ppm of carbonate ions are brought to the wash bath by the detergent itself, on top of the already present natural water hardness.
