Abstract

A toning composition which employs one or more of the propylene and butylene oxide-based glycol ethers with propylene glycol for removing sebum from the skin of a user without stinging and without dissolving and removing to any significant degree the intercellular lipids critical to the retention of moisture in the skin.

Claims

1. A toning composition which consists essentially of:

a glycol ether portion of one or more of the propylene and butylene oxide-based glycol ethers;

propylene glycol; and

an inert carrier, wherein the glycol ether portion and propylene glycol are selected and proportioned so that the glycol ether portion and propylene glycol together define or possess a combined solubility parameter of from about 8 to about 11.

2. A toning composition as defined in claim 1, wherein the glycol ether portion and propylene glycol are selected and present in the toning composition in amounts whereby an initial sebumeter reading of less than about 250 micrograms per square centimeter, taken just prior to application of the astringent composition to a user'"'"'s face, is not recovered for at least about four hours on average after such application.

3. A toning composition as defined in claim 1, wherein the glycol ether portion and propylene glycol are selected and present in the toning composition in amounts whereby an initial sebumeter reading of less than about 200 micrograms per square centimeter, taken just prior to application of the astringent composition to a user'"'"'s face, is not recovered for about seven hours on average after such application.

4. A toning composition as defined in claim 1, wherein the glycol ether portion and propylene glycol are selected and present in the toning composition in amounts whereby an initial sebumeter reading of less than about 200 micrograms per square centimeter, taken just prior to application of the astringent composition to a user'"'"'s face, is not recovered for about eight hours on average after such application.

5. A toning composition as defined in claim 1, wherein the glycol ether portion comprises less than about five percent by weight of the composition.

6. A toning composition as defined in claim 2, wherein the glycol ether portion comprises less than about five percent by weight of the composition.

7. A toning composition as defined in claim 3, wherein the glycol ether portion comprises less than about five percent by weight of the composition.

8. A toning composition as defined in claim 4, wherein the glycol ether portion comprises less than about five percent by weight of the composition.

9. A toning composition as defined in claim 1, wherein the glycol ether portion and propylene glycol together comprise five percent or less by weight of the toning composition.

10. A toning composition as defined in claim 2, wherein the glycol ether portion and propylene glycol together comprise five percent or less by weight of the toning composition.

11. A toning composition as defined in claim 3, wherein the glycol ether portion and propylene glycol together comprise five percent or less by weight of the toning composition.

12. A toning composition as defined in claim 4, wherein the glycol ether portion and propylene glycol together comprise five percent or less by weight of the toning composition.

13. A toning composition as defined in claim 1, wherein the glycol ether portion is comprised of one or more glycol ethers from the group consisting of propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, tetrapropylene glycol methyl ether, propylene glycol n-butyl ether, dipropylene glycol n-butyl ether, butylene glycol methyl ether, butylene glycol ethyl ether, butylene glycol n-butyl ether, dibutylene glycol methyl ether, dibutylene glycol ethyl ether, and dibutylene glycol n-butyl ether.

14. A toning composition as defined in claim 1, wherein the inert carrier is water.

15. A process for removing sebum from the skin of a user, comprising the step of applying a toning composition as defined in any of claims 1-14 to the skin of such a user.
