Abstract
Official abstract text for this publication.
Cleaning booster for cleaning dirty laundry is provided, wherein the cleaning booster is of formula (I) wherein b is 2 to 4; wherein x is 0 to 2; wherein each R is independently selected from the group consisting of a hydrogen, a C 1-22 alkyl group and a —CH 2 C(═O)R 1 group; wherein each R 1 is independently of formula (II) wherein the * indicates the point of attachment to formula (I); wherein R 2 is selected from the group consisting of a hydrogen and a C 1-22 alkyl group; wherein each R 3 and R 4 is independently selected from the group consisting of a hydrogen and a C 1-2 alkyl group, with the proviso that at least one of R 8 and R 9 is a hydrogen in each subunit α; and wherein α is 0 to 30.
First claim
Opening claim text (preview).
We claim: 1 . A cleaning booster for cleaning dirty laundry, wherein the cleaning booster is of formula (I) wherein b is 2 to 4; wherein x is 0 to 2; wherein each R is independently selected from the group consisting of a hydrogen, a C 1-22 alkyl group and a —CH 2 C(═O)R 1 group; wherein each R 1 is independently of formula (II) wherein the * indicates the point of attachment to formula (I); wherein R 2 is selected from the group consisting of a hydrogen and a C 1-22 alkyl group; wherein each R 3 and R 4 is independently selected from the group consisting of a hydrogen and a C 1-2 alkyl group, with the proviso that at least one of R 3 and R 4 is a hydrogen in each subunit a; wherein a is 0 to 30; and wherein 70 to 100 mol % of the R 1 groups in the cleaning booster are of formula (II) wherein a is 2 to 30. 2 . The cleaning booster of claim 1 , wherein 70 to 100 mol % of the R 1 groups in the cleaning booster of formula (II) are of formula (IIa) R 5 —O—[CH 2 CH(R 6 )O] y —* (IIa) wherein the * indicates the point of attachment to formula (I); wherein R 5 is selected from the group consisting of a hydrogen and a C 1-22 alkyl group; wherein each R 6 is independently selected from the group consisting of a hydrogen and a C 1-2 alkyl group; and wherein y is 2 to 30. 3 . The cleaning booster of claim 1 , wherein 70 to 100 mol % of the R 1 groups in the cleaning booster of formula (II) are of formula (IIb) R 7 —O-(EO) h —(PO) i -(EO) j -* (IIb) wherein the * indicates the point of attachment to formula (I); wherein R 7 is selected from the group consisting of a hydrogen and a C 1-12 alkyl group; wherein EO is an ethylene oxide group; wherein PO is a propylene oxide group; wherein h is 0 to 30; wherein i is 0 to 30; wherein j is 0 and 30; and wherein h+i+j is 2 to 30. 4 . The cleaning booster of claim 1 , wherein b is 2; wherein x is 1 and R is a methyl group. 5 . The cleaning booster of claim 3 , wherein R 7 is a C 1-4 alkyl group. 6 . The cleaning booster of claim 3 , wherein h is 0 to 1; wherein i is 2 to 5; and wherein j is 2 to 6. 7 . A laundry additive comprising a mixture of a cleaning booster of claim 1 and water. 8 . The laundry additive of claim 7 , wherein the laundry additive is a liquid.
