Abstract
The invention relates to a highly alkaline or mildly alkaline detergent composition having enhanced cleaning properties. The detergent combines a source of alkalinity and a blend of nonionic surfactants that enhances cleaning starchy soils. The blend of nonionic surfactants preferably includes an alkyl polyglycoside surfactant and a silicon surfactant having a hydrophobic silicon group and a pendant hydrophilic group. Preferably, the blend of nonionic surfactants includes a surfactant having a hydrophobic group and an ethylene oxide residue containing group and a polymer additive. A method for removing soil from an article is provided.
Claims38
An alkaline detergent composition comprising:
- (a) an effective soil removing amount of a source of alkalinity;
- and
- (b) an effective soil removing amount of a surfactant blend comprising:
- (i) an alkyl polyglycoside surfactant;
- and
- (ii) a silicone surfactant comprising a hydrophobic silicone group and a pendant hydrophilic group;
- wherein the detergent composition provides a use solution having a detergent concentration of between about 500 ppm and 2,000 ppm exhibiting a surface tension of less than about 35 dynes/cm.
A method for removing soil from an article, the method comprising:
- (a) contacting an article surface containing a starchy soil with an aqueous detergent composition comprising:
- (i) an effective soil removing amount of a source of alkalinity;
- and
- (ii) an effective soil removing amount of a surfactant blend comprising an alkyl polyglycoside surfactant and a silicone surfactant, wherein the silicone surfactant includes a hydrophobic silicone group and a pendant hydrophilic group.
