Abstract

Composition and methods are provided for analgesic cleansing compositions, which may be either wash-off or leave-on cleansing compositions. Such compositions comprise a number of surfactants and a number of analgesic compounds, and may optionally comprise antibacterial agents and/or a cosmetically suitable carrier. A method of making an analgesic soap composition is also provided. A method of using a wash-off analgesic cleansing composition is also provided.

First claim

What is claimed is:

1. An analgesic cleansing composition comprising: a cosmetically suitable carrier including at least 50 wt. % of one or more alcohols selected from the group consisting of isopropyl alcohol and ethanol based on the total weight of the analgesic cleansing composition;
and a leave-on cleansing composition, which comprises: at least one surfactant; and at least one analgesic compound to alleviate pain in a user, wherein the concentration of the at least one analgesic is from 0.01% to 30% by weight, relative to the total weight of the analgesic cleansing composition.

2. The analgesic cleansing composition of claim 1 , in which the cosmetically suitable carrier comprises ethanol.

3. The analgesic cleansing composition of claim 1 , in which the cosmetically suitable carrier comprises isopropanol.

4. The analgesic cleansing composition of claim 1 , in which the cosmetically suitable carrier further comprises water.

5. The analgesic cleansing composition of claim 1 , in which the at least one surfactant comprises an anionic surfactant.

6. The analgesic cleansing composition of claim 1 , in which the at least one analgesic compound comprises a topical analgesic compound selected from Aleurites moluccanus bakoly seed oil, aluminum acetate, benzyl alcohol, camphor, capsaicin, Capsicum frutescens fruit, Capsicum frutescens resin, Cedrus deodora wood extract, decursinol, diphenylhydramine, benzocaine, Ginkgo leaf terpenoids, hydrocortisone, Juniperus communis sprout extract, Juniperus oxycedrus wood tar, lauryl PEG-8 dimethicone, lidocaine, Meconopsis horridula flower extract, menthol, methyl nicotinate, methyl salicylate, ethyl salicylate, Ocimum tenuiflorum oil, Papaver rhoeas seed extract, pentafluoropropane, phenol, Pinus palustris resin extract, Piper longum fruit, Piper nigrum fruit, Piper nigrum seed, pramocaine, Saposhnikovia divaricata root extract, humic acid, turpentine, bendazac, benzyldamine, bufexamac, diethylamine salicylate, etofenamate, felbinac, fepradinol, feprazone, flufenamic acid, ibuprofen, imidazole salicylate, isonixin, ketoprofen, nimesulide, phenylbutazone, piktoprofen, piroxicam, proglumetacin, sadicylamide, salol, salicylic acid, suxibuzone, ufenamate, or salts thereof.

7. The analgesic cleansing composition of claim 6 , in which the at least one topical analgesic compound comprises methyl salicylate.

8. The analgesic cleansing composition of claim 1 , further comprising at least one additive selected from a natural polymer, a synthetic polymer, a semi-synthetic polymer, an antibacterial agent, a fragrance, a humectant, a dye, a pigment, an exfoliant, a conditioning agent, a plant extract, plant matter, an essential oil, an oil, a wax, a silicone oil, a silicone wax, a chelator, a vitamin, a vitamin derivative, an alkali metal halide, and combinations thereof.

9. The analgesic cleansing composition of claim 8 , in which at least one of the at least one additive increases the viscosity of the composition.

10. The analgesic cleansing composition of claim 1 , further comprising a deposition aid.

11. The analgesic cleansing composition of claim 10 , in which the deposition aid is cationally charged.

12. The analgesic cleansing composition of claim 10 , in which the deposition aid encapsulates the at least one analgesic compound.

13. A method of producing an analgesic cleansing composition comprising combining at least one anionic surfactant with at least one analgesic composition and a cosmetically suitable carrier to create a mixture, wherein the at least one topical analgesic compound is present at a concentration of 0.01% to 30% by weight, relative to the total weight of the analgesic cleansing composition; wherein the cosmetically suitable carrier comprises at least 50% by weight of one or more alcohols selected from the group consisting of isopropyl alcohol and ethanol based on the total weight of the analgesic cleansing composition;
and homogeneously mixing to create an analgesic cleansing composition; in which the amount of analgesic cleansing composition is sufficient to provide analgesia upon contact with the skin.

14. The method of claim 13 , in which the at least one topical analgesic compound comprises a compound selected from Aleurites moluccanus bakoly seed oil, aluminum acetate, benzyl alcohol, camphor, capsaicin, Capsicum frutescens fruit, Capsicum frutescens resin, Cedrus deodora wood extract, decursinol, diphenylhydramine, benzocaine, Ginkgo leaf terpenoids, hydrocortisone, Juniperus communis sprout extract, Juniperus oxycedrus wood tar, lauryl PEG-8 dimethicone, lidocaine, Meconopsis horridula flower extract, menthol, methyl nicotinate, methyl salicylate, ethyl salicylate, Ocimum tenuiflorum oil, Papaver rhoeas seed extract, pentafluoropropane, phenol, Pinus palustris resin extract, Piper longum fruit, Piper nigrum fruit, Piper nigrum seed, pramocaine, Saposhnikovia divaricata root extract, humic acid, turpentine, bendazac, benzyldamine, bufexamac, diethylamine salicylate, etofenamate, felbinac, fepradinol, feprazone, flufenamic acid, ibuprofen, imidazole salicylate, isonixin, ketoprofen, nimesulide, phenylbutazone, piktoprofen, piroxicam, proglumetacin, sadicylamide, salol, salicylic acid, suxibuzone, ufenamate, or salts thereof.

15. The method of claim 14 , in which the at least one topical analgesic compound comprises methyl salicylate.

16. The method of claim 13 , in which the analgesic cleansing composition further comprises at least one additive selected from a natural polymer, a synthetic polymer, a semi-synthetic polymer, an antibacterial agent, a fragrance, a humectant, a deposition aid, a dye, a pigment, an exfoliant, a conditioning agent, a plant extract, plant matter, an essential oil, an oil, a wax, a silicone oil, a silicone wax, a chelator, a vitamin, a vitamin derivative, an alkali metal halide, and combinations thereof.
