Claims
- 1. A method of using zeolite P having a silicon to aluminium ratio not greater than 1.33 (zeolite MAP) as a carrier material for a liquid, viscous-liquid or oily nonionic surfactant in a free-flowing particulate detergent composition or component therefor, which method comprises treating
- (i) a particulate carrier material comprising from 10 to 100 wt % (anhydrous basis) of zeolite MAP and selected from the group consisting of:
- (a) zeolite MAP in powder form,
- (b) a spray-dried, dry-mixed or granulated granular material comprising from 10 to 80 wt % of zeolite MAP and from 20 to 90 wt % (based on the carrier material) of other compatible detergent ingredients optionally including one or more detergent active compounds but excluding liquid, viscous liquid or oily nonionic surfactants, with
- (ii) a liquid, viscous-liquid or oily nonionic surfactant, the weight ratio of the liquid, viscous-liquid or oily nonionic surfactant to the particulate carrier material being within the range of from 0.1:1 to 0.75:1.
- 2. A method as claimed in claim 1 wherein the weight ratio of the liquid, viscous-liquid or oily nonionic surfactant to the zeolite MAP is within the range of from 0.1:1 to 1:1.
- 3. A method as claimed in claim 1, wherein the ratio of liquid, viscous-liquid or oily nonionic surfactant to the zeolite MAP is at least 0.35:1.
- 4. A method as claimed in claim 3, wherein the ratio of liquid, viscous-liquid or oily nonionic surfactant to the zeolite MAP is at least 0.45:1.
- 5. A method as claimed in claim 1, wherein the zeolite MAP has a particle size d.sub.50 within the range of from 0.1 to 5.0 micrometers wherein the quantity d.sub.50 indicates that 50 wt % of particles have a diameter smaller than that figure.
- 6. A method as claimed in claim 5, wherein the zeolite MAP has a particle size d.sub.50 within the range of from 0.4 to 1.0 micrometers.
- 7. A method as claimed in claim 1, wherein the zeolite MAP has a particle size distribution such that at least 90 wt % are smaller than 10 micrometers, at least 85 wt % are smaller than 6 micrometers and at least 80 wt % are smaller than 5 micrometers.
- 8. A method as claimed in claim 7, wherein the zeolite MAP has a particle size distribution such that at least 95 wt % are smaller than 10 micrometers, at least 90 wt % are smaller than 6 micrometers and at least 85 wt % are smaller than 5 micrometers.
- 9. A method as claimed in claim 1, which comprises from 2 to 45 wt % of the ingredient (ii), based on the total of the carrier material (i) and the ingredient (ii).
- 10. A method as claimed in claim 1, wherein the particulate carrier material comprises from 50 to 80 wt % (based on the carrier material) of zeolite MAP.
- 11. A method as claimed in claim 1, wherein the liquid, viscous-liquid or oily nonionic surfactant is sprayed in liquid or liquefied form onto the particulate carrier material.
- 12. A method as claimed in claim 1, which comprises mixing and granulating the zeolite MAP, the liquid, viscous-liquid, oily or waxy ingredient, and optionally other ingredients, in a high-speed mixer/granulator.
- 13. A method as claimed in claim 1, wherein the nonionic surfactant is a C.sub.10 -C.sub.20 aliphatic alcohol ethoxylated with an average of from 1 to 20 moles of ethylene oxide per mole of alcohol.
- 14. A method as claimed in claim 13, wherein the nonionic surfactant is a C.sub.12 -C.sub.15 is primary or secondary aliphatic alcohol ethoxylated with an average of from 1 to 10 moles of ethylene oxide per mole of alcohol.
- 15. A detergent composition or component prepared by a method as claimed in claim 1, which comprises from 20 to 80 wt % (based on the composition or component) of zeolite MAP, from 15 to 40 wt % of the liquid, viscous-liquid or oily nonionic surfactant, and optionally binder, water and other ingredients to 100 wt %.
- 16. A detergent composition or component as claimed in claim 15, having a bulk density of at least 700 g/l.
