Claims
- 1. A method for preparing a diluted laundry concentrate comprising:
- a) providing a laundry concentrate composition in the form of a water-in-oil emulsion containing at least about 2% by weight water and comprising a mixture of at least one non-ionic surfactant and at least one water insoluble oil containing a polar proton sharing group and having a melting point below about 30.degree. C., said non-ionic surfactant being the condensation product of an aliphatic alcohol having from about 6 to 26 carbon atoms with ethylene oxide, said oil being selected from the group consisting of saturated aliphatic alcohols or acids containing from about 6 to 12 carbon atoms and unsaturated liquid fatty C.sub.16 to C.sub.18 acids or alcohols, said concentrate characterized by a viscosity of at least about 10 cps; and
- b) diluting said concentrate with at least one volume of water per volume of concentrate such that said concentrate is at least partially converted into a liquid crystal phase dispersion, providing a diluted concentrate having a viscosity of at least about 50 cps.
- 2. The method of claim 1 wherein said concentrate is diluted with from about one to about 4 volumes of water per volume of concentrate.
- 3. The method of claim 1 wherein said oil contains a polar proton sharing group selected from hydroxy, carboxylic, amine or amido and has a melting point below 30.degree. C.
- 4. The method of claim 3 wherein said oil is a fatty alcohol having from about 6 to 12 carbon atoms.
- 5. The method of claim 1 wherein said concentrate has a viscosity of from about 200 to 1000 cps and said diluted concentrate has a viscosity of from about 50 to 1000 cps.
- 6. The method of claim 5 wherein said diluted concentrate has a viscosity of about 300 to 800 cps.
- 7. The method of claim 2 wherein said surfactant comprises a non-ionic surfactant selected from the group consisting of C.sub.9 to C.sub.11 mixed alcohols condensed with 6-10 moles of ethylene oxide and C.sub.12 to C.sub.15 mixed alcohols condensed with 10-12 moles of ethylene oxide.
- 8. The method of claim 7 wherein the ratio of surfactant to oil present in the concentrate ranges from about 1:0.4 to 1:2.2.
- 9. The method of claim 1 wherein said diluted concentrate has a viscosity equal to or higher than the viscosity of said undiluted concentrate.
