Benefits of technology

[0009] The present invention further relates to a process for making the present compositions comprising the steps of dispersing the dialkyl quaternary a

Problems solved by technology

As the vesicles deposit onto the surfaces being treated with the compositions, the vesicles are able to effectively deliver water-soluble active materials to the surface, which previously has been difficult to achieve.

example 14

[0039] In this example, 2 terry swatches of 40 grams each are rinsed for 5 minutes in 1 liter of tap water containing 2 ml of each of the compositions of Examples 11-13 above, and the terry swatches are subsequently spun dry in a commercial washing machine. The swatches are line dried overnight, and the odor impact of the swatches treated with the composition of Example 11 are compared to swatches treated with the compositions of Example 12 and 13 respectively.

[0040] The table below shows a higher odor impact for the terry swatches treated with the preferred compositions of the invention.

Abstract

Compositions for effectively delivering a water-soluble active material to a surface comprise: (a) from about 1% to about 30%, by weight of the composition, of a dialkyl quaternary ammonium compound having the formula: wherein R1 and R2 are independently C12 to C20 saturated alkyl chains; Y is wherein R4 is ethyl or isopropyl; R3 and R5 are independently methyl, ethyl, hydroxyethyl, or hydroxypropyl; m is 1, 2, or 3; n is 1 or 2; p is 0 or 1; and X− is a suitable anion; (b) from about 0.01% to about 10%, by weight of the composition, of water-soluble active material having a C log P of less than about 2.0; and (c) at least about 60%, by weight of the composition, of water; wherein the compositions contain vesicles having a vesicle permeability index of less than about 1.3. Processes to make the compositions comprise the steps of dispersing the dialkyl quaternary ammonium compound and the water-soluble active material in an aqueous solution to form vesicles having a vesicle permeability index of less than about 1.3.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims priority to U.S. Provisional Application Ser. No. 60 / 511,732, filed Oct. 16, 2003, the disclosure of which is incorporated by reference herein.FIELD OF THE INVENTION [0002] The present invention relates to aqueous compositions comprising vesicles having a vesicle permeability index of less than about 1.3 to facilitate the delivery of water-soluble active materials having a C log P of less than about 2.0 to surfaces being treated with the compositions. BACKGROUND OF THE INVENTION [0003] A number of commercialized products, such as fabric softeners, hard surface cleaners, hair conditioners, agrochemical products and paints, contain active materials that are water-soluble. Oftentimes, these products contain water-soluble active materials that are intended to be deposited onto a surface being treated with the product. However, if these water-soluble materials are in a highly aqueous environment, it can be difficult to...
