摘要: A toilet bar is provided whose components include from 10 to 70% of a soap, from 0.1 to 3% of a cellulosic polymer, and from 0.1 to 3% of a water-soluble carboxylate polymer. The carboxylate polymer is formed from a mixture of monomers comprising a water-soluble carboxylic containing vinyl monomer and a water-insoluble vinyl monomer, the water-insoluble monomer constituting at least 30 mole % of the polymer.

摘要: A transparent bar is disclosed which requires the components to fit within three critical ratios. The composition comprises a mixture of alkanolammonium and alkali metal C.sub.12 --C.sub.22 atom fatty acid salts, the mole ratio of alkanolammonium to alkali metal fatty acid salt being from about 0.1 to less than 1.0. A liquid solvent system must also be present which includes an amount of water and free alkanolamine in a weight ratio ranging from greater than 0.25 to less than 1.0. The weight ratio of total fatty acid salts to solvent must range from greater than 0.02 to less than 1.0.

摘要: N-substituted aldonamides are synthesized by the reaction of alkylamines and aldonolactone. Commercially available sources of aldonolactones (e.g., lactobiono-1,5-lactone) include aldonic acid (e.g., lactobionic acid). The presence of the acid leads to the formation of an ammonium salt impurity. The ammonium salt formation during the synthesis of N-alkyl aldonamides was minimized by the addition of an external acid. External acids and, optionally, emulsifiers were utilized to substantially reduce or eliminate the formation of an ammonium salt and to obtain N-substituted aldonamides of high purity.
