Definitions

  • US4414130 discloses a "readily disintegrable, insoluble, detergent builder particulate agglomerate comprising [aluminosilicate] held together by a water soluble binder.”
  • a binder which is mentioned is Polyclar ®, a PVP supplied by GAF.
  • Methods of manufacturing agglomerates include the use of a fine spray of water to promote adhesion.
  • Example 2(B) discloses a solution of polyvinyl pyrollidone and polyvinyl alcohol which is agglomerated with zeolite. This patent is not, however, concerned with the problems of formulating and processing dye transfer inhibiting agents.
  • GB-A-1 348 212 relates to detergent compositions with improved dye-transfer control characteristics comprising 60 to 95 % by weight of nonionic detergent and a homopolymer of vinylpyrrolidone or a copolymer of vinylpyrrolidone and a suitable comonomer.
  • polyvinyl pyrrolidone is useful as a dye transfer inhibitor, other polymers are being sought which are even more effective.
  • a more effective polymer is one which can be used in smaller quantities than polyvinyl pyrollidone to achieve the same effect, and which is cheaper.
  • the present invention provides a high density agglomerate which comprises copolymers of N-vinylpyrrolidone and N-vinylimidazole, at levels of 5% to 50% by weight, comprising very low levels of surfactant, ie. less than 2 % by weight.
  • the present invention also provides a process in which a premix of specific hygroscopic dye transfer inhibition polymer with zeolite (or other powder) is prepared prior to agglomeration.
  • the present invention provides a free-flowing powder having a bulk density of at least 600 g/l comprising:
  • the free-flowing powder comprises (a) from 50% to 75% by weight (on anhydrous basis) of aluminosilicate and (b) a mixture of polyamine N-oxide and copolymer of N-vinylpyrrolidone and N-vinylimidazole, the total polymer level being from 10% to 30% by weight of the powder.
  • the mixture of polyamine N-oxide and copolymers of N-vinylpyrrolidone and N-vinylimidazole is typically in the ratio of from 5:1 to 1:5, and is preferably about 1:1.
  • the present invention provides a process for making free-flowing particles comprising hygroscopic powders of polymers comprising the steps of:
  • the aqueous binder in step (b) is preferably an aqueous solution of polyamine N-oxide. Again, less than 2 % by weight of surfactant is present.
  • step of (c) drying the mixture of the premix and aqueous solution of binder to form the free-flowing particles may also be included in the process.
  • the aluminosilicate, and any other salt present is usually fully hydrated prior to the high shear mixer.
  • An essential ingredient of the free-flowing powders of the present invention is a copolymer of N-vinylpyrrolidone and N-vinylimidazole dye transfer inhibiting agent.
  • Polymeric dye transfer inhibiting agents are normally incorporated into detergent compositions in order to inhibit the transfer of dyes from colored fabrics onto fabrics washed therewith. These polymers have the ability to complex or adsorb the fugitive dyes washed out of dyed fabrics before the dyes have the opportunity to become attached to other articles in the wash.
  • further polymeric dye transfer inhibiting agents are polyamine N-oxide polymers, polyvinylpyrrolidone polymers, polyvinyloxazolidones and polyvinylimidazoles or mixtures thereof.
  • polyamine N-oxide polymers suitable for use contain units having the following structure formula :
  • the N-O group can be part of the polymerisable unit (P) or can be attached to the polymeric backbone or a combination of both.
  • Suitable polyamine N-oxides wherein the N-O group forms part of the polymerisable unit comprise polyamine N-oxides wherein R is selected from aliphatic, aromatic, alicyclic or heterocyclic groups.
  • R is selected from aliphatic, aromatic, alicyclic or heterocyclic groups.
  • One class of said polyamine N-oxides comprises the group of polyamine N-oxides wherein the nitrogen of the N-O group forms part of the R-group.
  • Preferred polyamine N-oxides are those wherein R is a heterocyclic group such as pyrridine, pyrrole, imidazole, pyrrolidine, piperidine, quinoline, acridine and derivatives thereof.
  • Another class of said polyamine N-oxides comprises the group of polyamine N-oxides wherein the nitrogen of the N-O group is attached to the R-group.
  • polyamine N-oxides are the polyamine oxides whereto the N-O group is attached to the polymerisable unit.
  • Preferred class of these polyamine N-oxides are the polyamine N-oxides having the general formula (I) wherein R is an aromatic, heterocyclic or alicyclic groups wherein the nitrogen of the N-0 functional group is part of said R group.
  • the polyamine oxides can be obtained in almost any degree of polymerisation.
  • the degree of polymerisation is not critical provided the material has the desired water-solubility and dye-suspending power.
  • the average molecular weight is within the range of 500 to 1000,000; preferably from 1,000 to 50,000, more preferably from 2,000 to 30,000, most preferably from 3,000 to 20,000.
  • the N-vinylimidazole N-vinylpyrrolidone polymers used in the present invention have an average molecular weight range from 5,000-1,000,000, preferably from 20,000-200,000.
  • Highly preferred polymers for use in detergent compositions according to the present invention comprise a polymer selected from N-vinylimidazole N-vinylpyrrolidone copolymers wherein said polymer has an average molecular weight range from 5,000 to 50,000 more preferably from 8,000 to 30,000, most preferably from 10,000 to 20,000.
  • the average molecular weight range was determined by light scattering as described in Barth H.G. and Mays J.W. Chemical Analysis Vol 113,"Modern Methods of Polymer Characterization".
  • N-vinylimidazole N-vinylpyrrolidone copolymers have an average molecular weight range from 5,000 to 50,000; more preferably from 8,000 to 30,000; most preferably from 10,000 to 20,000.
  • Sodium aluminosilicate may take many forms.
  • One example is crystalline aluminosilicate ion exchange material of the formula Na z [(AlO 2 ) z ⁇ (SiO 2 ) y ] ⁇ xH 2 O wherein z and y are at least about 6, the molar ratio of z to y is from about 1.0 to about 0.4 and z is from about 10 to about 264.
