Abstract
Official abstract text for this publication.
Described are personal care, preferably skin care compositions, comprising polyolefin blends comprising at least one metallocene catalyzed polyolefin with a density above 0.90 g/cm 3 , at least one metallocene catalyzed polyolefin with a density equal to or below 0.90 g/cm 3 , provided that the average melt index for the polyolefin blend is greater than 7; and a cosmetically acceptable hydrocarbon oil, provided that the composition does not contain ethylene acrylic copolymer.
First claim
Opening claim text (preview).
The invention claimed is: 1. An oil gel skin care composition comprising: (a) a polyolefin blend comprising: at least one high density metallocene catalyzed polyolefin selected from the group consisting of polyethylene and ethylene/octene copolymers, wherein the high density polyolefin has a density above 0.90 g/cm 3 , wherein the high density polyolefin is present in an amount of at least 6.25 weight %, based on the total weight of the composition; and at least one low density metallocene catalyzed polyolefin selected from ethylene/octene copolymers, wherein the low density polyolefin has a density equal to or below 0.90 g/cm 3 , wherein the low density polyolefin is present in an amount of at least 4.17 weight %, based on the total weight of the composition; provided that the average melt index for the polyolefin blend is greater than 7; and (b) a cosmetically acceptable hydrocarbon oil, wherein the cosmetically acceptable hydrocarbon oil is C 14 -C 22 hydrocarbon oil, wherein the hydrocarbon oil is present in an amount of at least 87 weight %, based on the total weight of the composition; provided that the composition does not contain ethylene acrylic copolymer. 2. The oil gel skin care composition of claim 1 , wherein the pH of the skin care composition is between 5 and 7. 3. The oil gel skin care composition of claim 1 , wherein the polyolefin blend further comprises at least one of a silicone oil or silicone elastomer. 4. The oil gel skin care composition of claim 1 , wherein the polyolefin blend further comprises an emollient. 5. The oil gel skin care composition of claim 1 , wherein the ratio of at least one metallocene catalyzed polyolefin with a density above 0.90 g/cm 3 to the at least one metallocene catalyzed polyolefin with a density equal to or below 0.90 g/cm 3 is 1:1. 6. The oil gel skin care composition of claim 1 , wherein the ratio of at least one metallocene catalyzed polyolefin with a density above 0.90 g/cm 3 to the at least one metallocene catalyzed polyolefin with a density equal to or below 0.90 g/cm 3 is 2:1. 7. The oil gel skin care composition of claim 1 , provided that the average melt index for the polyolefin blend is greater than 8. 8. The oil gel skin care composition of claim 1 , wherein provided that the average melt index for the polyolefin blend is greater than 8.5.
