  • Patent number: 5994288
    Abstract: A process for forming solid cast detergent products comprising the steps of: (a) forming an aqueous detergent slurry comprising from about 60 to about 90 parts by weight of solid detergent ingredients, per 100 parts of total detergent slurry weight, said solid detergent ingredients comprising: (i) from about 5 to about 50 parts by weight of a surfactant; (ii) from about 0.1 to about 10 parts by weight of a salt-form builder component; (iii) from about 30 to about 75 parts by weight of a hydrated alkaline component;(b) adding from about 0.5 to about 10 parts by weight of a sugar surfactant selected from the group consisting of an alkyl polyglycoside, a glucamide, and mixtures thereof, to form a uniform dispersion; and (c) casting said uniform dispersion to form a solid cast detergent product.
    Type: Grant
    Filed: February 24, 1998
    Date of Patent: November 30, 1999

  • Patent number: 5725470
    Abstract: A process for the remediation of soil containing volatile organic compounds which comprises the steps of: (1) forming an emulsifier comprising: (a) from about 70 to about 99% by weight of a sugar surfactant selected from the group consisting of an alkyl polyglycoside, a glucamide, and mixtures thereof; and (b) from about 1 to about 30% by weight of a nonionic surfactant, other than said sugar surfactant which, when combined with said sugar surfactant, provides a hydrophilic-lipophilic balance of from about 8.0 to about 13.0; (2) mixing said emulsifier with said unwanted contaminants to form a stable emulsion; and (3) removing said stable emulsion from said soil.

  • Patent number: 5330674
    Abstract: The germicidal efficiency of an aqueous disinfectant cleaning composition is increased by incorporating an effective amount of a compound of the formula IR--O(--G).sub.n Iwherein R is an alkyl group having from about 8 to about 22 carbon atoms, G is a saccharide residue having 5 or 6 carbon atoms; and n is a number from 1 to 10 into an aqueous composition which contains a compound of the formula IIR.sub.2 R.sub.3 R.sub.4 R.sub.5 NXwherein R.sub.2 is a benzyl or C.sub.1-4 alkyl substituted benzyl group, and each of R.sub.3, R.sub.4, and R.sub.5 is independently an alkyl group having from about 8 to about 22 carbon atoms.
