  • Patent number: 5612308
    Abstract: Detergent compositions comprising a surfactant system that is either (1) a mixture nonionic and zwitterionic detergent surfactants; (2) a mixture of nonionic and amphoteric (non-zwitterionic) detergent surfactants; or (3) short chain nonionic detergent surfactant, the nonionic detergent surfactants preferably being short chain and/or having peaked distribution; optional hydrophobic cleaning solvent; and polycarboxylate, especially dicarboxylate, detergent builder provide superior cleaning of all of the soils commonly found in the bathroom. The compositions have a pH of from about 1 to about 5.5, preferably from about 2 to about 4 when the dicarboxylate builder is used. The compositions are in the form of aqueous liquids. Short chain peaked distribution nonionic detergent surfactants provide surprisingly superior sudsing characteristics.

  • Patent number: 5454983
    Abstract: Aqueous, liquid hard surface detergent compositions contain zwitterionic and cationic detergent surfactants and monoethanolamine and/or other specific beta-aminoalkanols as solvents and/or buffers for improved spotting/filming and good cleaning.

  • Patent number: 5126061
    Abstract: Microcapsules which are prepared using coacervation processes and/or which have a complex structure in which there is a large central core of encapsulated material, preferably perfume, and the walls contain small wall inclusion particles of either the core material or some other material that can be activated to disrupt the wall are disclosed. The microcapsules that are prepared by coacervation and contain perfume are especially desirable for inclusion in fabric softener compositions that have a pH of about 7 or less and which contain cationic fabric softener. The encapsulated perfume preferably does not contain large amounts of relatively water-soluble ingredients. Such ingredients are added separately to the fabric softener compositions. Ingredients that have high and low volatilities as compared to, e.g., the desired perfume, can either be added to, or removed from, the perfume to achieve the desired volatility.

  • Patent number: 4961871
    Abstract: Powdered, abrasive, hard surface cleansers containing micro-encapsulated perfume wherein the capsules are essentially water-insoluble, but can become perfume permeable during use by the combined action of water and abrasive. The preferred capsules are formed from gelatin and a polyanionic material by coacervation techniques and then are cross-linked to provide controlled water insolubility.
