TRANSPARENT COMPOSITIONS

Abstract

A composition comprising: A) a transparent gel base, comprising: a) a polymeric thickener, b) a solubiliser, c) a pH adjuster, d) a calcium sequestrant, e) water, f) an optional protein, g) an optional active material, which is selected from disaccharides, lactones, inorganic salts, diacids and mixtures thereof, h) an optional dye preferably comprising violet, blue, red or mixtures thereof, wherein the solubiliser comprises a mixture of at least two components, said mixture comprising at least one high HLB component having an HLB value of from 10 to 20 and at least one low HLB component having an HLB value of from 1 to less than 10, and B) a hydrogel particle, comprising: a) a matrix, and b) a silicone or blend of silicones, wherein the silicone or blend of silicones has an average molecular weight of greater than 400 Da, and wherein the particle has an average diameter of 0.1 to 15 mm and wherein the silicone is present in an amount of from 5 to 40 wt % by total weight of the particle. A method of treating a substrate includes contacting the substrate with the composition and applying a releasing force to the hydrogel particle to release the silicone.

Description

EXAMPLES

[0184] The invention will now be illustrated by the following non-limiting examples. In the examples and throughout this specification, all percentages are by weight based on total composition unless indicated otherwise.

Example 1: Composition in Accordance with the Invention

[0185] The followed method is used to manufacture a composition according to the invention. [0186] The polymeric thickener is added to water and mixed until fully dispersed. [0187] Water soluble materials are then added to the mixture. [0188] In a separate vessel, fragrance and other oil soluble materials are blended with the solubiliser. [0189] This mixture is then added to the main batch and mixed until a transparent solution is obtained. [0190] The pH is adjusted with sodium hydroxide to between 3 and 4.5. [0191] The hydrogel beads are added with gentle stirring.
