This is achieved through a composition that comprises alkyl substituted dihydroxy benzene in combination with select substituted phenol compound. The composition is also seen to have anti-malodour benefits.

First claim

1 . An antimicrobial composition comprising:
a an alkyl substituted dihydroxy benzene wherein the alkyl group comprises 2 to 10 carbon atoms; b a substituted phenol compound selected from one or more of 4-sec butyl phenol, 4-cyclo pentyl phenol, 4-benzyl phenol, and 2-cyclo pentyl phenol; and c a cosmetically acceptable base.

2 . The composition according to claim 1 , wherein the alkyl substituted dihydroxy benzene comprises 2 to 6 carbon atoms.

3 . The composition according to claim 1 , wherein the alkyl substituted dihydroxy benzene is a hexyl resorcinol having the chemical structure

4 . The composition according to claim 1 , wherein the composition comprises from 0.0005 to 10% by weight of the alkyl substituted dihydroxy benzene by weight of the composition.

5 . The composition according to claim 1 , wherein the composition comprises from 0.001 to 5% by weight of the substituted phenol compound.

6 . The composition according to claim 1 , wherein the cosmetically acceptable base comprises a gel, emulsion, lotion, paste, spray, or cream.

7 . The composition according to claim 6 , wherein said cosmetically acceptable base comprises water, a surfactant or combinations thereof.
