Abstract
A liquid cleansing composition, for use as a hard surface cleaner, comprises (A) a base liquid composition comprising (a) a base composition comprising: (1) an anionic surfactant, (2) a nonionic surfactant, (3) a non-polar grease-removal solvent, (4) a water-soluble detergent builder salt, (5) optionally, a perfume, and (6) optionally, a dye; and (b) water; and (B) an abrasive. The liquid cleansing composition is in the form of a liquid crystalline material of the smectic type. A method of making the liquid cleansing composition comprises sequential addition of the various ingredients.
Claims31
A method for the preparation of a liquid crystalline material of the smectic type, useful as a liquid cleanser, consisting essentially of
- (I) about 40 to about 90 parts by weight of a base liquid composition of
- (a) about 7 to about 20 parts by weight of a base composition of
- (1) about 2.5 to 7.5 parts by weight of an anionic surfactant, said anionic surfactant comprising an organic hydrophobic moiety and at least one water-solubilizing salt group selected from the group consisting of sulphonate, sulphate, carboxylate, phosphonate and phosphate,
- (2) about 1.25 to 6.5 parts by weight of a nonionic surfactant,
- (3) about 1.8 to 5.4 parts by weight of a non-polar grease-removal solvent selected from non-cyclic, saturated hydrocarbons,
- (4) about 1 to 5 parts weight of a water-soluble detergent builder salt,
- (5) 0 to about 1 part by weight of a perfume,
- (6) optionally, a dye in an amount sufficient to impart a predetermined color to said liquid cleanser composition,
- (7) optionally, a preservative in an amount effective to prevent degradation of said liquid cleanser composition, and
- (8) 0 to 1 part by weight of a maleic acid/isobutylene sodium salt copolymer;
- and
- (b) about 15 to about 60 parts by weight of water;
- and
- (II) about 10 to to about 60 parts by weight of an insoluble abrasive;
- said method comprising:
- (A) dispersing said anionic surfactant, with said water-solubilizing group in its acid form, in said water;
- (B) converting said anionic surfactant, with said water-solubilizing group in its acid form, dispersed in said water, to said anionic surfactant, with said water-solubilizing group in its salt form;
- and
- (C) dispersing the remaining ingredients of said liquid cleanser composition in the aqueous dispersion formed in said step (B).
