Abstract

The disclosed aspects and embodiments provide compositions, systems, and methods for applying a warming cosmetic composition in a manner that provides unexpected levels of temperature increase (on a per mass basis) and prevents aggregation of inorganic components of the composition. In one aspect, a composition is provided that includes an anhydrous medium and at least one exothermic heating agent, wherein the composition is configured to provide increased temperature when exposed to water sufficient to initiate an exothermic reaction and mixing energy, as compared to the composition when exposed to water in the absence of mixing energy.

First claim

The embodiments of the disclosure in which an exclusive property or privilege is claimed are defined as follows:

1. A composition, consisting of:
19.6% by weight of magnesium sulfate,
8% by weight of PEG-7 caprylic/capric glycerides,
47.65% by weight of PEG-8,
5% by weight of glycerin,
1% by weight of citric acid,
13.2% by weight of dimethicone,
1.8% by weight of dimethiconol,
2% by weight of silica dimethyl silylate,
1% by weight of silica,
0.05% by weight of fragrance,
water, and
0.3% by weight of capryloyl salicylic acid,
wherein when the composition is exposed to water and subjected to cyclical mechanical mixing having a peak cyclic or oscillation frequency of 168 Hz, the composition provides a temperature increase of 4-6° C. greater than a temperature increase of the composition subjected to manual mixing.

2. The composition of claim 1 , wherein the cyclical mechanical mixing is provided by a mechanical device.

3. The composition of claim 2 , wherein the mechanical device is configured to provide a cyclical mechanical motion to produce the cyclical mechanical mixing.

4. The composition of claim 3 , wherein the cyclical mechanical motion is rotational or oscillating.

5. The composition of claim 3 , wherein the cyclical mechanical motion is provided by a brush.

6. The composition of claim 1 , wherein the composition is configured to warm for at least 60 seconds upon exposure to water and cyclical mechanical mixing.

7. The composition of claim 1 , wherein the composition is configured to produce an amount of warming energy that is greater than the amount of cyclical mechanical mixing provided to the composition.

8. A kit, comprising: the composition of claim 1 ; and a brush configured to provide a mechanical motion having a peak cyclic or oscillation frequency of from about 40 Hz to about 240 Hz.

9. A method of cleansing, comprising applying a mixture of the composition of claim 1 and water onto a skin portion or to hair; and applying cyclical mechanical mixing energy to the mixture to cleanse the skin portion or hair.

10. The method of claim 9 , wherein cleansing the skin portion further includes exfoliating the skin portion.

11. The method of claim 9 , wherein cleansing the skin portion further includes removing make-up from the skin portion.

12. The method of claim 9 , wherein the cyclical mechanical mixing energy is provided by a cyclic mechanical motion.

13. The method of claim 12 , wherein the cyclic mechanical motion is rotational or oscillating.

14. The method of claim 12 , wherein the cyclic mechanical motion is provided by a brush.

15. The method of claim 12 , wherein the cyclic mechanical motion has a peak cyclic or oscillation frequency of from about 40 Hz to about 240 Hz.

16. The method of claim 9 , wherein the composition warms for at least 60 seconds upon exposure to water and cyclical mechanical mixing energy.
