Claims
- 1. A process for producing a detergent having a liquid surfactant component comprising
- (a) a non-ionic surfactant selected from the group consisting of adducts of a C.sub.10 -C.sub.20 -fatty alcohol with from 2 to 8 moles ethylene oxide per mole fatty alcohol;
- (b) an anionic surfactant selected from the group consisting of surface active soaps, sulfates, sulfonates, and mixtures thereof; and
- (c) polyethylene glycol having a molecular weight of from about 200 to 600; and a particulate solids component comprising
- (d) a first finely divided fraction having an average particle size of from about 0.01 to 30 microns; and
- (e) a second more coarsely divided fraction having an average particle size of from about 200 to 2000 microns;
- wherein the particulate solids component includes at least one member selected from the group consisting of a builder, a redeposition inhibitor, an optical brightener, a detergency-promoting enzyme, a bleach, a bleach activator, and a foam inhibitor; said process comprising
- (f) admixing the liquid components of the detergent including the liquid surfactant component with the solid components of the detergent which do not substantially chemically interact with each other or with the liquid components to form a suspension;
- (g) wet grinding the suspension to reduce the particle size of the solid components to an average particle size of 30 microns or less to provide a ground suspension;
- (h) admixing the ground suspension with the second coarsely divided solids fraction; and
- (i) degassing the mixture.
- 2. The process of claim 1, further including the steps of degassing the ground suspension, degassing the coarsely divided solids fraction before admixing with the ground suspension, or both.
- 3. The process of claim 1, wherein the mean particle size of the solid components in the ground suspension is less than the mean pore size of the solid components in the coarsely divided solids fraction.
- 4. The process of claim 1, wherein the detergent contains less than about 5% by weight unbound water.
- 5. The process of claim 1, wherein the detergent contains less than about 5% by volume of gaseous components which are gaseous at room temperature.
- 6. The process of claim 1, wherein the detergent contains less than about 3% by volume gaseous components.
- 7. The process of claim 1, wherein the detergent has a final viscosity of from about 10,000 to 1,000,000 mPas.
- 8. The process of claim 1, wherein the second coarsely divided fraction comprises a granulated solid.
- 9. The process of claim 1, wherein the non-ionic and anionic surfactants are present in a ratio of from about 1.1:1 to 1.5:1 and the polyethylene glycol is present in an amount of from about 2 to 10% by weight based on the total weight of detergent.
- 10. The process of claim 1, wherein the total liquid surfactant component comprises from about 25 to 40% by weight of the detergent.
- 11. The process of claim 1, wherein the adduct contains from 3 to 5 moles ethylene oxide per mole fatty acid.
- 12. The process of claim 1, wherein the fatty alcohol is a C.sub.12 -C.sub.18 -fatty alcohol.
- 13. The process of claim 1, wherein the non-ionic surfactant comprises a mixture of adducts of fatty alcohols having different numbers of carbon atoms.
- 14. The process of claim 1, wherein the anionic surfactant comprises a sulfonate and a soap.
- 15. The process of claim 1, wherein the soap also functions as a foam inhibitor.
- 16. The process of claim 1, wherein the soap is an alkali metal salt of a C.sub.18 -C.sub.24 -fatty acid.
- 17. The process of claim 1, wherein the polyethylene glycol component (c) has a molecular weight of from about 300 to 400.
