Abstract
A solid free-flowing particulate laundry detergent composition including: (a) from 0.1 wt % to 5 wt % polymer particle comprising: (i) from 70 wt % to 90 wt % co-polymer and (ii) from 10 wt % to 30 wt % salt; and (b) from 35 wt % to 80 wt % spray-dried particle including: (i) from 8 wt % to 24 wt % alkyl benzene sulphonate anionic detersive surfactant; (ii) from 5 w % to 18 wt % silicate salt; (iii) from 0 wt % to 10 wt % sodium carbonate; and (iv) from 0 wt % to 5 wt % carboxylate polymer.
Claims11
A solid free-flowing particulate laundry detergent composition comprising:
- (a) from about 0.1 wt % to about 5 wt % polymer particle comprising:
- (i) from about 70 wt % to about 90 wt % co-polymer, wherein the co-polymer comprises:
- (i.i) from about 50 to less than about 98 wt % structural units derived from about one or more monomers comprising carboxyl groups;
- (i.ii) from about 1 to less than about 49 wt % structural units derived from about one or more monomers comprising sulfonate moieties;
- and
- (i.iii) from about 1 to about 49 wt % structural units derived from about one or more types of monomers selected from ether bond-containing monomers represented by formulas (I) and (II):
- wherein in formula (I), R0 represents a hydrogen atom or CH3 group, R represents a CH2 group, CH2CH2 group or single bond, X represents a number 0-5 provided X represents a number 1-5 when R is a single bond, and R1 is a hydrogen atom or C1 to C20 organic group;
- wherein in formula (II), R0 represents a hydrogen atom or CH3 group, R represents a CH2 group, CH2CH2 group or single bond, X represents a number 0-5, and R1 is a hydrogen atom or C1 to C20 organic group;
- and
- (ii) from about 10 wt % to about 30 wt % salt, wherein the salt is selected from sulphate salt and/or carbonate salt;
- and
- (b) about 35 wt % to about 80 wt % spray-dried particle comprising:
- (i) from about 8 wt % to about 24 wt % alkyl benzene sulphonate anionic detersive surfactant;
- (ii) from about 5 w % to about 18 wt % silicate salt
- (iii) from 0 wt % to 10 wt % sodium carbonate;
- and
- (iv) from 0 wt % to 5 wt % carboxylate polymer.
