Abstract

The pulvurent effervescent topical treatment compositions comprise:
at least 50% wt. of a gas generating system which comprises both a gas generating constituent as well as a complementary reactive acid constituent, which constituents, when combined in the presence of water or another largely aqueous medium generates a gas, preferably carbon dioxide; 5-50% wt. of an anionic soap and/or anionic surfactant constituent; 0.0001-1.5% wt. of an antimicrobial constituent; 0.0001-3 an exogenous product of Sclerotium rolfsii, and, optionally one or more filler constituents, preferably based on materials which are inert with respect to the gas generating constituent and which also are inert with respect to the antimicrobial constituent; further optionally, one or more further constituents which may be included to provide a desired aesthetic benefit, e.g., a fragrance, colorant and/or a desired technical benefit, e.g. an abrasive, to the pulvurent effervescent topical treatment compositions of which they form a part.

The invention also provides effervescing, foamed topical treatment composition which are used as topical treatment compositions.

First claim

The invention claimed is:

1. A pulvurent effervescent topical treatment composition which comprises:
at least 50% wt. of a gas generating system which comprises both a gas generating constituent as well as a complementary reactive acid constituent, which constituents, when combined in the presence of water or another largely aqueous medium generates carbon dioxide;
5-50% wt. of an anionic soap and/or anionic surfactant constituent;
0.0001-1.5% wt. of an antimicrobial constituent;
0.0001-3 an exogenous product of Sclerotium rolfsii,
a chelating agent,
characterized in that the composition excludes inert particulate materials.

2. A composition according to claim 1 wherein the antimicrobial constituent is selected from: salicylic acid and/or salicylic acid derivatives and/or a salt form thereof.

3. A composition according to claim 1 wherein the antimicrobial constituent is selected from: lactic acid and/or lactic acid derivatives and/or a salt form thereof.

4. A composition according to claim 3 wherein the antimicrobial constituent is an alkyl lactate.

5. A composition according to claim 1 wherein which comprises a cocosulfate anionic surfactant.

6. A composition according to claim 1 , wherein the said composition is effective against one or more of the following microorganisms: E. coli, S. aureus, P. aeruginosa , and E. hirae.

7. A composition according to claim 1 , wherein the chelating agent is selected from the group consisting of: aminopolycarboxylic acids and salts thereof wherein the amino nitrogen has attached thereto two or more substituent groups, alkali metal, ammonium and substituted ammonium polyacetates, carboxylates, polycarboxylates and polyhydroxysulfonates, tetra sodium salt of glutamic acid-N,N-diacetic acid, methyl-glycine-diacetic acid, sodium and potassium salts of ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, N-hydroxyethylethylenediaminetriacetic acid.

8. A composition according to claim 1 in the form of a tableted body.

9. A composition according to claim 1 , wherein the composition is absorbed onto a carrier substrate and forms a wipe article.

10. A method for providing an antimicrobial benefit to an epidermal surface which method includes the step of:
applying an antimicrobially effective amount of a topical germicidal composition according to claim 1 .

11. A pulvurent effervescent topical treatment composition consisting of:
at least 50% wt. of a gas generating system which comprises both a gas generating constituent as well as a complementary reactive acid constituent, which constituents, when combined in the presence of water or another largely aqueous medium generates carbon dioxide;
5-50% wt. of an anionic soap and/or anionic surfactant constituent;
0.0001-1.5% wt. of an antimicrobial constituent;
0.0001-3 an exogenous product of Sclerotium rolfsii,
optionally, one or more further constituents selected from organic solvents, fragrances, perfumes, colorants and optical brighteners, nonionic surfactants, cationic surfactants, hydrotropes, chelating agents, pH buffers and pH adjusting agents.

12. A composition according to claim 11 wherein the antimicrobial constituent is selected from: salicylic acid and/or salicylic acid derivatives and/or a salt form thereof.

13. A composition according to claim 11 wherein the antimicrobial constituent is selected from: lactic acid and/or lactic acid derivatives and/or a salt form thereof.

14. A composition according to claim 13 wherein the antimicrobial constituent is an alkyl lactate.

15. A composition according to claim 11 wherein which comprises a cocosulfate anionic surfactant.

16. A composition according to claim 11 , wherein the said composition is effective against one or more of the following microorganisms: E. coli, S. aureus, P. aeruginosa , and E. hirae.

17. A method for providing an antimicrobial benefit to an epidermal surface which includes the step of:
applying an antimicrobially effective amount of a composition according to claim 11 to thereby reduce the incidence of undesired microorganisms present on the treated epidermal surface.
