Fabric conditioning compsns

Abstract

An aqueous, liquid fabric conditioning composition and a method for making such a composition where the composition comprises a quaternary ammonium cationic softening compound, a perfume having a ClogP of 2 or more and an oily perfume carrier for the perfume, the carrier having a ClogP of 3.5 or more where the composition comprises an emulsion in which 80% or more by weight of the droplets in the emulsion have a mean diameter of from 0.4 to 60 microns, as measured using a Malvern particle size analyser with a 45 mm lens for D[0,1] measurements and both a 45 mm and a 1000 mm lens for D[0,9] measurements.

Description

field of invention

[0001] The present invention relates to fabric conditioning compositions, and in particular, the present invention relates to fabric conditioning compositions comprising an emulsion whose droplets have an average diameter within a certain size range. Background of the invention

[0002] Rinse added fabric conditioning compositions are known. Generally, these compositions comprise aqueous lamellar phase dispersions having fabric softening properties.

[0003] A problem often encountered with conventional fabric conditioning compositions is that perfume is lost during product storage or insufficient delivery to fabrics.

[0004] Inadequate delivery of perfume to fabrics is particularly problematic with dilute fabric conditioning compositions, which is defined as compositions containing less than 7.5% by weight of quaternary ammonium softening materials.

[0005] To overcome this problem, more perfume ingredients can be added to dilute compositions. Howeve...

Examples

Embodiment

[0131] The invention is now illustrated by the following non-limiting examples. Those skilled in the art will easily devise further modifications, but these all fall within the scope of the present invention.

[0132] The embodiments of the present invention are represented by numbers, and the comparative examples are represented by letters.

[0133] Examples 1-10 and A-F; Evaluation of Perfume Delivery on Cloth

[0134] The compositions of Examples 1 to 7 and A to F are prepared according to the aforementioned first preferred method, except that when the premixture is ground with water, the volume of the mixture delivered through the mill is less than 2 batches, such as A ~F. The degrees of grind of the compositions are shown in Table 2.

[0135] Examples 8-10 were prepared on a 200ml scale. The quaternary ammonium compound, fragrance carrier, fatty acid and tallow alcohol are co-melted together. The water was heated to 55°C and the co-melt was added to the water over ...
