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

1 . An antimicrobial composition comprising:
(i) 0.1 to 10 wt % of a compound of the 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; and
(ii) an essential oil compound of general formula 2 having the structure

where R1 is H, OH or OR where R is 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, carvacol, (E)-2(prop-1-enyl) phenol, 2-propyl phenol, 4-pentyl phenol, 4-sec-butylphenol, 2-benzyl phenol, or eugenol or combinations thereof.

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 compound of general formula 1 is tetrahydroxypropyl ethylenediamine having the formula

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

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

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

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

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

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

10 . The method as claimed in claim 9 , 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 9 , wherein the step of wiping or rinsing is carried out 10 seconds to 2 minutes after applying the composition.

13 . The antibacterial composition as claimed in claim 8 , wherein the anionic surfactant is soap.

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