Abstract
A fabric rinsing composition, free of cationic softening compound, in the form of an oil-in-water emulsion prepared by a phase inversion temperature process. The product of the invention provides a good rinsing while efficiently depositing perfume onto the treated fabric.
Claims16
A fabric rinsing composition free of cationic compound, comprising:
- from 0.1 to 18% of a perfuming ingredient or composition;
- from 0.1 to 25% of a stabilising oil;
- from 0.1 to 18% of a non-ionic surfactant system comprising a polyethylene glycol stearyl ether having a hydrophilic lipophilic balance above 10;
- and
- from 0.01 to 50% of an acid susceptible of forming water-soluble salts of alkaline-earth compounds;
- the remainder of the composition being water;
- all the percentages being given by weight relative to the total weight of the composition;
- the composition being in the form of an oil-in-water nanoemulsion obtained by a phase inversion temperature process.

A process for preparing a fabric rinsing composition in the form of an oil-in-water emulsion free of cationic compounds comprising:
- a) preparing a mixture comprising
- from 0.1 to 18% of a perfuming ingredient or composition;
- from 0.1 to 25% of a stabilizing oil;
- from 0.1 to 18% of a non-ionic surfactant system comprising a polyethylene glycol stearyl ether having a hydrophilic lipophilic balance above 10;
- b) preparing a mixture comprising
- from 0.01 to 50% of an acid susceptible of forming water-soluble salts of alkaline-earth compounds;
- water
- c) admixing the mixture obtained in step a) and the mixture obtained in step b) and stirring to form an emulsion
- d) heating the emulsion to its phase inversion temperature;
- e) cooling the emulsion to a temperature below its phase inversion temperature;
- all percentages being given by weight relative to the total weight of the fabric rinsing composition.
