Cellulosics, laundry detergents

Laundry detergent may also contain polyethylene glycol, a polymer that prevents dirt from redepositing on the clothes. This function used to be the job of phosphates. Another polymer used for this purpose is carboxy methyl cellulose, which is derived from natural cellulose but is very soluble in water. 

A powdered soap-based laundry detergent contains 44% tallow soap, 18% sodium salt of a-sulfonated 1 1 methyl stearate-methyl palmitate mixture, 9% sodium silicate, 10% Na2S04, 2.5% ethoxylated cocoethanolamide, 1.4 cellulose, 0.2% fluorescent whitener, 0.7% enzyme, 0.5% perfume, and 5% water [77].

Carboxymethyl cellulose (CMC) plays an important role in food industry. Because of high viscosity, nontoxicity, and nonallergic nature, it is used as a viscosity modifier or thickener and to stabilize emulsions in various products including ice cream. It is also a constituent of many nonfood products, such as jellies, toothpaste, laxatives, diet pills, water-based paints, detergents, textile, and various paper products. In laundry detergents, CMC is used as a soil suspension polymer which creates a negatively charged barrier to soils in the wash solution. CMC is also used as a lubricant in nonvolatile eye drops. 

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. 

Alternating MA copolymers, including the styrene comonomer, have applications potential as detergent builders.In many cases, such copolymers improve the sequestering properties of the detergent formulation. SMA-Carbowax 350 (Union Carbide) combinations were shown useful modifiers for poly(vinyl alcohol) and cellulosic ether film packets for laundry detergents.

Water-Soluble Films. Water-soluble films can be produced from such polymers as poly(vinyl alcohol) (PVOH), methylceUulose, poly(ethylene oxide), or starch (qv) (see Cellulose ethers Polyethers Vinyl polymers). Water-soluble films are used for packaging and dispensing portions of detergents, bleaches, and dyes. A principal market is disposable laundry bags for hospital use. Disposal packaging for herbicides and insecticides is an emerging use. 

Since their commercial introduction during the 1940s as components of proprietary detergents and laundry preparations, these products have found extensive usage in the whitening of paper and textile materials. Disperse FBAs are available for whitening hydrophobic fibres and solvent-soluble FBAs impart fluorescence to oils, paints, varnishes and waxes. Approximately 75% of commercially established FBAs are stilbene derivatives with inherent substantivity for paper and cellulosic textiles, but the remainder come from about twenty different chemical classes. These include aminocoumarins (6%), naphthalimides (3%), pyrazoles and pyrazolines (each about 2%), acenaphthenes, benzidine sulphones, stilbene-naphthotriazoles, thiazoles and xanthenes (each about 1%). FBAs of these and other chemical types are discussed in detail in Chapter 11 of Volume 2.
