Abstract
Solid laundry detergents, dishwashing detergents and cleaners which are obtained by mixing gemini surfactants of the formula (I), R1CH(OH)CHR3(OCH2CH2)nOCHR4CH(OH)R2 (I) in which R1 and R2, independently of one another, are linear or branched alkyl and/or alkenyl radicals having 4 to 22 carbon atoms, R3 and R4, independent of one another, each represents a hydrogen or an alk(en)yl radical having from 1 to 22 carbon atoms and n is a number from 5 to 400, with inorganic or organic carriers.
Claims23
A solid detergent composition prepared by a process comprising mixing:
- (i) a gemini surfactant of the general formula (I);
- R1CH(OH)CHR3(OCH2CH2)nOCHR4CH(OH)R2 (I)
- wherein R1 and R2, independent of one another, each represents an alk(en)yl radical having from 4 to 22 carbon atoms, R3 and R4, independent of one another, each represents a hydrogen or an alk(en)yl radical having from 1 to 22 carbon atoms and n represents a number of from 5 to 400;
- and (ii) a carrier.
A solid detergent composition comprising:
- (i) a gemini surfactant of the general formula (I);
- R1CH(OH)CHR3(OCH2CH2)nOCHR4CH(OH)R2 (I)
- wherein R1 and R2, independent of one another, each represents an alk(en)yl radical having from 4 to 22 carbon atoms, R3 and R4, independent of one another, each represents a hydrogen or an alk(en)yl radical having from 1 to 22 carbon atoms and n represents a number of from 5 to 400;
- and (ii) a carrier;
- wherein the composition is a freeflowing, granular solid.
A process for the preparation of a solid detergent composition, said process comprising providing (i) a gemini surfactant of the general formula (I);
- R1CH(OH)CHR3(OCH2CH2)nOCHR4CH(OH)R2 (I)
- wherein R1 and R2, independent of one another, each represents an alk(en)yl radical having from 4 to 22 carbon atoms, R3 and R4, independent of one another, each represents a hydrogen or an alk(en)yl radical having from 1 to 22 carbon atoms and n represents a number of from 5 to 400, and (ii) a carrier;
- and combining the gemini surfactant and the carrier.
