AI Technical Summary
Technical Problem
Existing surfactants in detergent compositions, such as those produced by addition-polymerizing styrene oxide with organic compounds and lower alkylene oxides, lack sufficient cleaning power and anti-soil redeposition ability.
Method used
Development of an alkylene oxide polymer with two types of hydrophobic groups, including a hydrocarbon group with an aromatic ring and another hydrocarbon group, combined with a structural unit derived from polyalkylene oxide, to enhance detergency and anti-soil redeposition.
Benefits of technology
The alkylene oxide polymer exhibits excellent detergency and anti-soil redeposition ability, improving the cleaning performance of detergent compositions by preventing soil redeposition on fabrics and enhancing the dispersibility of muddy soils.
