  • Patent number: 6562776
    Abstract: This invention is directed to detergent compositions which employ sulfonated linear alkylbenzenes as surfactants, wherein the sulfonated linear alkylbenzenes have a higher content of the sulfonated 2-phenyl alkylbenzene isomers than was previously available in sulfonated phenyl alkylbenzene surfactants of the prior art. Cleaning compositions according to the invention are more effective as cleaning agents over their counterparts of prior art which contain sulfonated linear alkylbenzenes having lower contents of the 2-phenyl alkylbenzene isomers, owing to an unexpected increase in tolerance of water hardness minerals normally associated with precipitation of the active detergent agent. Solid sulfonate salts of alkylbenzenes are also provided, including dry formulations containing same.

    Abstract: Detergent formulations incorporating crystalline alkali metal silicate granules provide enhanced performance in removing sebum dirt stains at low dosages of detergent in the wash. The detergent formulations are prepared by combining an alkali metal silicate having a high pH value with a nonionic surfactant and an acid precursor of an anionic surfactant capable of having a lamellar orientation. The formulation is granulated by tumbling in an agitating mixer while increasing the bulk density at elevated temperatures to yield alkali metal silicate granules having a bulk density of from 0.6 to 1.2 g/ml.

  • Publication number: 20010031716
    Abstract: Laundry detergent compositions giving improved oily soil detergency in the machine wash, especially on knitted cotton and knitted polyviscose fabrics, contain an anionic sulphonate surfactant and a zwitterionic betaine surfactant in a weight ratio of 2:1 to 99:1, preferably 3:1 to 25:1. The preferred anionic surfactant is linear alkylbenzene sulphonate and the preferred betaine surfactant is cocoamidopropyl betaine.

  • Patent number: 6284722
    Abstract: The present invention is targeted to obtain a high-density granular detergent composition for clothes washing having sufficient detergency even when the amount of dosage is small without lowering its detergency even after long-term storage by blending a non-soap anionic surfactant and a crystalline alkali metal silicate in a state of non-contact as much as possible. The high-density granular detergent composition for clothes washing, the granular detergent composition having a bulk density of from 0.7 to 1.2 g/cm3, including (A) a non-soap anionic surfactant; (B) a crystalline alkali metal silicate; and (C) a metal ion capturing agent other than Component (B).

  • Publication number: 20010018409
    Abstract: Laundry detergent compositions contain a sulphate or sulphonate anionic surfactant and a defined cationic surfactant in a weight ratio of 1:1 to 99:1. The cationic surfactant is a quaternary ammonium salt containing an ethoxylated alkyl chain. The compositions exhibit enhanced removal of oily soil.
