Embodiment 1

[0040] The personal care compositions of the present invention include aqueous dispersions comprising ethylene acrylic acid copolymer. Examples of such aqueous dispersions include the following:

[0041] Batch 1: 41.7% solids aqueous dispersion of ethylene acrylic acid and metallocene catalyzed polyolefin (commercially available from The Dow Chemical Company under the trademark HYPOD 8510, prepared using Dow's BLUEWAVE technology).

Embodiment 2

[0043] Exemplary personal care compositions comprise the components shown in Table 1 on a weight / weight (wt %) basis.

[0044] Table 1

[0045]

[0046] Mix Lot 1 with Base Surfactant. Heat slowly to 74°C with stirring (approximately 500 rpm) with an overhead stirrer. Continue stirring until the surfactant is in solution. Add pearlescent agent at about 500 rpm, maintain this speed for 15 minutes, then cool slowly to about 35°C. Increase the stirrer speed to 750 rpm. Stir for about 15 minutes. Add the cationic polymer slowly and stir for about 30 minutes. Add 10% citric acid and stir for about 10 minutes. Add Glydant preservative and make up to 100 g with qs. water. Stir for 15 minutes at about 500 rpm.

Embodiment 3

[0047] Embodiment 3 (comparative example)

[0048] A conventional personal care shampoo composition comprises the components shown in Table 2 on a weight / weight (wt %) basis.

[0049] Table 2

[0050]

[0051] The base surfactant was slowly heated to 74°C with stirring (approximately 500 rpm) with an overhead stirrer. Continue stirring until the surfactant is in solution. Add pearlescent agent at about 500 rpm, maintain this speed for 15 minutes, then cool slowly to about 35°C. Increase the mixer speed to about 750 rpm, slowly add the silicone emulsion and mix for about 15 minutes. Add the cationic polymer slowly and stir for about 30 minutes. Add 10% citric acid and stir for about 10 minutes. Add Glydant preservative and make up to 100 g with qs. water. Stir for 15 minutes at about 500 rpm.

Abstract

Described are personal care compositions, comprising an aqueous dispersion comprising a metallocene catalyzed polyolefin and an ethylene acrylic acid copolymer; a cationic polymer; and a least one cosmetically acceptable surfactant, emollient, or cosmetic active, provided that the personal care composition contains less than 0.09 wt % of silicone, and preferably is substantially free of silicone.

Description

technical field [0001] This application relates to personal care compositions. Background technique [0002] Silicone deposition is known to improve the smooth feel of personal care compositions, especially hair conditioners, shampoos and body washes. [0003] However, balancing personal care components in a manner that promotes silicone deposition as opposed to promoting silicone wash-off is a major challenge in the art. One option is to develop new formulations that have similar aesthetics to silicones but do not contain silicones. Therefore, an important goal in the art is to generate such new formulations. Brief description of the invention [0004] In one embodiment, the present invention provides a personal care composition comprising an aqueous dispersion comprising a metallocene-catalyzed polyolefin and ethylene acrylic acid copolymer; a cationic polymer; and at least one cosmetically acceptable surface Active agent, emollient or cosmetic active agent, provided ...
