  • Patent number: 5534198
    Abstract: Detergent compositions having good filming/streaking characteristics contain effective amounts of specific substantive materials to increase the hydrophilicity of the glass. Preferred formulas contain a amphoteric, including zwitterionic, and optionally, but preferably, anionic detergent surfactant at levels (e.g., from about 0.02 to about 15%); hydrophobic solvent; alkaline material, especially volatile alkaline materials comprising monoethanolamine or certain beta-amino-alkanol compounds; and salt of polycarboxylate, preferably polyacrylate, polymer at effective levels (e.g., from about 0.01% to about 10%, by weight of the composition).

  • Patent number: 5531915
    Abstract: Detergent compositions containing conventional detergent surfactants, detergent builders, and the like, and a chelant selected from ethylenediamine-N,N'-diglutaric acid (EDDG) and 2-hydroxypropylenediamine-N,N'-disuccinic acid (HPDDS) are disclosed. Such compositions provide enhanced removal of organic stains, such as food and beverage stains. The EDDG and HPDDS are biodegradable and contain no phorphorus.

  • Patent number: 5531933
    Abstract: Aqueous, liquid hard surface detergent compositions having improved cleaning and good filming/streaking characteristics contain specific polycarboxylate detergent builders at critical levels. Preferred formulas contain a zwitterionic/anionic detergent surfactant mixture at levels (e.g., from about 0.02 to about 15%); hydrophobic solvent; alkaline material, especially volatile alkaline materials comprising monoethanolamine or certain beta-amino-alkanol compounds; and salt of ethylenediaminetetraacetic acid as the detergent builder in levels (e.g., from about 0.05% to about 0.5%, by weight of the composition).
