Abstract
A liquid laundry additive is provided, comprising a cleaning booster polymer having structural units of a monoethylenically unsaturated carboxylic acid monomer; structural units of an ethylenically unsaturated monomer of formula (I) wherein a is an average of 1-3; wherein b is an average of 1-3; wherein c is an average of 0-5; wherein d is 4-100; wherein A is an anion; and wherein M is a cation charge balancing the anion; and optionally, structural units of an ethylenically unsaturated monomer of formula (II) wherein each R2 is independently selected from a —C1-4 alkyl group; and wherein each R3 is independently selected from the group consisting of a hydrogen and a methyl group.
Claims8
A liquid laundry additive, comprising:
- a cleaning booster polymer, comprising:
- 50 to 95 wt %, based on dry weight of the cleaning booster polymer, of structural units of a monoethylenically unsaturated carboxylic acid monomer;
- 5 to 50 wt %, based on dry weight of the cleaning booster polymer, of structural units of an ethylenically unsaturated monomer of formula (I)
- wherein a is an average of 1-3;
- wherein b is 1;
- wherein c is 0;
- wherein d is 4-100;
- wherein A is an anion (preferably, a SO3− or a PO32−;
- more preferably, SO3−);
- and wherein M is an NH4+ charge balancing the anion;
- and
- 0 to 20 wt %, based on dry weight of the cleaning booster polymer, of structural units of an ethylenically unsaturated monomer of formula (II)
- wherein each R2 is independently selected from a —C1-4 alkyl group;
- and wherein each R3 is independently selected from the group consisting of a hydrogen and a methyl group.
