  • Patent number: 5700771
    Abstract: Disclosed is a detergent composition comprising a polyhydroxy fatty acid amide surfactant of the formula: ##STR1## wherein R.sup.1 is H, C.sub.1 -C.sub.4 hydrocarbyl, 2-hydroxy ethyl, 2 hyroxy propyl, or a mixture thereof, R.sup.2 is C.sub.5 -C.sub.31 hydrocarbyl, and Z is a polyhydroxy-hydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyls connected directly to said chain, or an alkoxylated derivative thereof, and a non-borate, non-borate-forming bleaching agent such as the persulfates and especially the percarbonate bleaches. Mixtures of non-perborates with bleach activators such as tetraacetyl ethylene diamine are also used in the compositions. Also disclosed is a method for cleaning substrates, such as fabrics, fibers, textiles, hard surfaces, etc., at temperatures below about 50.degree. C., especially below about 40.degree. C.

  • Patent number: 5589449
    Abstract: A particulate foam control agent comprises 1 to 30 parts silicone antifoam, 70 to 99 parts zeolite carrier, 1 to 60% of the antifoam of an organopolysiloxane polyoxyalkylene copolymer, deposited onto the zeolite carrier not later than the antifoam and 1 to 40 parts by weight of a polycarboxylate-type binder or encapsulant. This combination give good release in early stages, storage stability and powder characteristics.

  • Patent number: 5536432
    Abstract: A process for the production of a detergent composition having a predetermined relative humidity comprising forming a crude detergent composition having a relative humidity in excess of the predetermined level, for example in excess of 30% and contacting the said crude composition with a preconditioned gas having a relative humidity below the predetermined relative humidity wherein the temperature of the crude composition is maintained below the temperature at which the crude composition agglomerates thereby to form a low relative humidity detergent composition.
