Abstract

The present invention provides an epilatory composition comprising an admixture of a hydrocarbon resin material and a mineral oil in weight ratio of 1.3:1 to 2.8:1, and, a polyethylene in the form of a homopolymer. An advantage of the compositions of the present invention is that they can be heated to the correct temperature of use, and/or to the correct viscosity, in an advantageous time.

Claims (45)

1 . An epilatory composition comprising:

a hydrocarbon resin ;

a mineral oil in a weight ratio in the range of from 1.3:1 to 2.8:1; and

a polyethylene in the form of a homopolymer.

2 . The epilatory composition as claimed in claim 1 , wherein the ratio of hydrocarbon resin to mineral oil is in the range of from 1.8:1 to 2.1:1.

3 . The epilatory composition as claimed in claim 1 , wherein the ratio of hydrocarbon resin to mineral oil is in the range of from 2:1 to 2.05:1.

4 . The epilatory composition as claimed in claim 1 , wherein the hydrocarbon resin is selected from the group consisting of poly(methylstyrene-co-indene) and hydrogenated polycyclopentadiene resin.

5 . The epilatory composition as claimed in claim 1 , wherein the hydrocarbon resin is hydrogenated polycyclopentadiene resin.

6 . The epilatory composition as claimed in claim 1 , wherein the epilatory composition comprises from 55-70% wt/wt of hydrocarbon resin.

7 . The epilatory composition as claimed in claim 1 , wherein the epilatory composition comprises from 60-68% wt/wt of hydrocarbon resin.

8 . The epilatory composition as claimed in claim 1 , wherein the epilatory composition comprises from 64-66% wt/wt of hydrocarbon resin material.

9 . The epilatory composition as claimed in claim 1 , wherein the mineral oil is selected from the group consisting of argan oils and castor oils.

10 . The epilatory composition as claimed in claim 1 , wherein the mineral oil is paraffin oil.

11 . The epilatory composition as claimed in claim 1 , wherein the epilatory composition comprises from 25-40% wt/wt of the mineral oil.

12 . The epilatory composition as claimed in claim 1 , wherein the epilatory composition comprises from 30-35% wt/wt of the mineral oil.

13 . The epilatory composition as claimed in claim 1 , wherein the epilatory composition comprises from 32-34% wt/wt of the mineral oil.

14 . The epilatory composition as claimed in claim 1 , wherein the polyethylene has a molecular weight in the range of from 100 to 1000.

15 . The epilatory composition as claimed in claim 1 , wherein the polyethylene has a molecular weight in the range of from 250 to 800 unified mass units.

16 . The epilatory composition as claimed in claim 1 , wherein the polyethylene has a molecular weight in the range of from 300 to 600 unified mass units.

17 . The epilatory composition as claimed in any of claim 1 , wherein the polyethylene has a molecular weight in the range of from 400 to 450 unified mass units.

18 . The epilatory composition as claimed in claim 1 , wherein the polyethylene is present in an amount in the range of from 0.1% to 5% by weight of the epilatory composition.

19 . The epilatory composition as claimed in claim 1 , wherein the polyethylene is present in an amount in the range of from 0.5% to 3.0% by weight of the epilatory composition.

20 . The epilatory composition as claimed in claim 1 , wherein the polyethylene is present in an amount in the range of from 0.75% to 1.5% by weight of the epilatory composition.

21 .- 22 . (canceled)

23 . An epilatory composition comprising:

63-65 wt % of a hydrocarbon resin;

33-35 wt % of a mineral oil; and

1-2 wt % of a polyethylene in the form of a linear homopolymer.

24 . An epilatory composition consisting essentially of:

60-68 wt % of a hydrocarbon resin;

30-35 wt % of a mineral oil; and

0.5-5 wt % of a polyethylene in the form of a linear homopolymer.

25 .- 26 . (canceled)

27 . The epilatory composition as claimed in claim 1 further comprising:

shea butter;

titanium dioxide;

a fragrance; and

a dye;

wherein the hydrocarbon resin comprises hydrogenated polycyclopentadiene resin;

wherein the mineral oil comprises paraffin oil;

wherein the polyethylene is in the form of a linear homopolymer; and

wherein the epilatory composition comprises:

64-66% of the hydrogenated polycyclopentadiene resin;

31-35% of the paraffin oil; and

0.8-1.2% of the polyethylene in the form of the linear homopolymer.
