Use of alkoxylated polyol derivatives for treating textiles
View Patent ↗Described is a process for washing, cleaning or aftertreatment of laundry comprising treating the laundry with compounds of formula (II): wherein R″, independently of each other, represent a hydrogen atom or a sulfur-containing group selected from the group consisting of OC—CH 2 —S—SO 3 M, SO 3 M, and wherein at least one R″ has to be one of the sulfur-containing groups, AO, independently of each other, represent C 2 H 4 O—, C 3 H 6 O— or C 4 H 8 O—, the indices x, y and z, independently of one another, are 0 or their sum have a value of from 1 to 500, M is a cation having at least one charge, and wherein if x, y or z is zero, than its corresponding substituent R″ is a hydrogen atom; and mixtures thereof.
1. A process for washing, cleaning or aftertreatment of laundry consisting of:
(1) contacting said laundry at a temperature of less than or equal to about 40° C., with an aqueous composition comprising:
wherein R″, independently of each other, represent a hydrogen atom or a sulfur-containing group selected from the group consisting of OC—CH 2 —S—SO 3 M and SO 3 M, and, wherein, at least one R″ is a sulfur-containing group, AO, independently of each other, represents C 2 H 4 O—, C 3 H 6 O— or C 4 H 8 O—, the indices x, y and z, independently of one another, are 0 or their sum has a value of from 1 to 500, M is a cation having at least one charge, provided that when any of x, y or z is zero, its corresponding substituent R″ is a hydrogen atom;
(b) at least one member selected from the group consisting of textile fiber cleaning surfactants and textile fiber softening agents; and
(c) water; and
(2) drying said laundry;
wherein the treated laundry exhibits reduced pilling.
2. The process of claim 1 , wherein, in formula (II) the sum of x+y+z is a number of from 10 to 100.
3. The process of claim 1 , wherein, the sum of x+y+z is a number of from 50 to 500.
4. The process of claim 1 , wherein, AO is exclusively C 2 H 4 O.
5. The process of claim 1 , wherein, AO is exclusively C 3 H 6 O.
6. The process of claim 1 wherein the compound of formula (II) is present in the composition in an amount of from about 0.1 to 90% by weight, based on the weight of the composition.
7. The process of claim 1 wherein the compound of formula (II) is present in the composition in an amount of from about 25 to 45% by weight, based on the weight of the composition.
8. The process of claim 1 wherein the textile fibers comprise at least one member selected from the group consisting of wool fibers and cotton fibers.
9. The process of claim 1 wherein said contacting step is washing or cleaning.
10. The process of claim 1 wherein said composition is a detergent composition.
