  • Patent number: 5045225
    Abstract: An antifoam composition and laundry detergent formulation including it. The antifoam composition comprises a selected alkylaminosilicone, finely divided filler particles and a hydrocarbon carrier oil. Optional ingredients include oil/water surfactants and silicone oils. The alkylaminosilicone reduces the surface tension of the hydrocarbon oil and renders the formulation self-hydrophobing.

  • Patent number: 5035826
    Abstract: A liquid detergent composition which is in liquid crystal form comprises a synthetic organic surface active agent, as the detergent component, which preferably includes one or more nonionic detergents of the ethoxylated higher fatty alcohol type, and a lesser proportion of anionic or cationic surfactant, such as sodium dialkyl sulfosuccinate or dicoco dimethyl ammonium chloride, a cosurfactant, such as tripropylene glycol butyl ether, a solvent for the soil, such as an isoparaffin of 9 to 11 carbon atoms or methyl cocoate (ester of methyl alcohol and coco acids) and water, with the water usually being the major component. Such compositions are useful for cold or room temperature cleaning of lipophilic soils, such as animal fats, from hard surfaces and from fabrics, and may be used as pre-treatments to loosen such soils from substrates to facilitate easier cleaning of dishes and laundry with conventional or the invented detergent compositions.
