Surfactants laundry-cleaning formulations

Several cleaning formulations for specific uses contain unreacted polyamines. Examples include mixtures of ammonium alkylbenzenesulfonate, solvents, and PIP which give good cleaning and shine performance on mirrors and other hard surfaces without rinsing (305), and a hard-surface cleaner composed of a water-soluble vinyl acetate—vinyl alcohol copolymer, EDA, cyclohexanone [108-94-1] dimethyl sulfoxide [67-68-5] a surfactant, and water (306). TEPA, to which an average of 17 moles of ethylene oxide are added, improves the clay sod removal and sod antiredeposition properties of certain hquid laundry detergents (307). 

Even as early as 1939, the soap industry began to create laundry detergents using surfactants that were supplied to the soap manufacturers by the petrochemical industry. Because the cleaning formulations prodnced from these synthetic detergents were a substantial improvement over soap products in use at the time, they soon gave rise to a global surfactant industry based on branched alkyl benzene (BAB) derived from branched paraffins. 

Uses Surfactant In detergent formulations for manual dishwashing, llq. detergents for laundry washing, general cleaning and hand washing used In conditioners and mild shampoo formulations... 

Uses SurfaclanL detergent, wetting agent in all-purpose cleaners, hard surfaces, fabrics, laundry detergents and prespotters, heavy-duty Industrial cleaners Features Effective replacement for alkyl phenol ethoxylates In cleaning formulations alkyl phenol ethoxylate free compat. with cationic, anionic, and nonlonic surfactants no gelling at any cones. 

Ether carboxylates are used not only in powdered detergents but in liquid laundry detergents for their hard water stability, lime soap dispersibility, and electrolyte stability they improve the suspension stability and rheology of the electrolyte builder [130,131]. Formulations based particularly on lauryl ether carboxylate + 4.5 EO combined with fatty acid salt and other anionic surfactants are described [132], sometimes in combination with quaternary compounds as softeners [133,163]. Ether carboxylates show improved cleaning properties as suds-controlling agents in formulations with ethoxylated alkylphenol or fatty alcohol, alkyl phosphate esters or alkoxylate phosphate esters, and water-soluble builders [134]. 

From the anionic surfactants (Table 1.1) the most relevant is LAS with an annual global production volume of more than 3 X 1061 in 2001. LAS has a wide application because of its excellent detersive properties and cost-performance ratio. Commercial LAS is applied mainly in the formulation of powder and liquid laundry detergents. The calcium salts are used as an emulsifier in pesticide formulations their amine salts are used in dry cleaning and as degreasing agents in the metal industry [14].
