Abstract

This invention relates to an antimicrobial composition, more particularly a personal care composition like a soap bar. It more particularly relates to a composition comprising an essential oil compound and a tetra hydroxy alkylene amine compound which interact synergistically to provide the desired result.

First claim

The invention claimed is:

1. An antimicrobial composition comprising:
(i) 0.1 to 10 wt % of a compound of general formula 1

where R1 to R4 are each independently a linear or branched carbon chain having 2 to 5 carbon atoms; and R5 is a carbon chain having 1 to 4 carbon atoms, wherein the compound of formula one is tetrahydroxypropyl ethylenediamine having the formula

and
(ii) 0.001 to 1 wt % of an essential oil compound of general formula 2 having the structure

where R1 is H, OH or OR where R is an alkyl chain with 1 to 5 carbon atoms;
R2 is a C1 to C6 linear alkyl group; or C3 to C6 branched alkyl group; or C5 to C6 cyclic or heterocyclic alkyl group; or a C6 aromatic group;
wherein said essential oil compound is selected from thymol, carvacrol, 2-propyl phenol, 4-pentyl phenol, 4-sec-butylphenol, 2-benzyl phenol, eugenol or combinations thereof;
wherein the composition is used for skin cleansing.

2. The antimicrobial composition as claimed in claim 1 , wherein the essential oil compound is thymol, carvacrol or eugenol.

3. The antimicrobial composition as claimed in claim 1 , wherein the composition additionally comprises terpineol.

4. The antimicrobial composition as claimed in claim 3 , comprising a mixture of terpineol and the essential oil compound thymol.

5. The antimicrobial composition as claimed in claim 1 , additionally comprising a cosmetically acceptable base.

6. The composition as claimed in claim 5 , wherein said cosmetically acceptable base comprises water, surfactant or combinations thereof.

7. The composition as claimed in claim 6 , wherein said surfactant is an anionic surfactant.

8. A method of providing antimicrobial efficacy to skin comprising the step of applying a composition as claimed in claim 1 on to a desired skin surface, followed by wiping the composition off the surface or rinsing the surface with water to be substantially free of said composition.

9. The antibacterial composition as claimed in claim 7 , wherein the anionic surfactant is soap.

10. The method as claimed in claim 8 , wherein said composition is applied to the desired skin surface after diluting the composition with water.

11. The method as claimed in claim 10 , wherein the composition is diluted with water to a concentration of 1 to 50%.

12. The method as claimed in claim 8 , wherein the step of wiping or rinsing is carried out 10 seconds to 2 minutes after applying the composition.

13. The method as claimed in claim 10 , wherein the composition is 2 to 20% by weight of the diluted solution.
