Antimicrobial composition
An antimicrobial composition with a synergistic combination of ingredients is described. Cosmetic compositions containing the antimicrobial composition with improved preservation properties are also described. The cosmetic compositions are effective in treating the skin to cleanse, moisturize and to reduce the effects of aging and photo damage and treat other skin conditions after being topically applied.
1. A cosmetic composition comprising:
an antimicrobial composition and a cosmetically acceptable base, wherein the antimicrobial composition comprises:
a. phenoxyethanol in a concentration of 0.2 to 1.0 wt. %;
b. caprohydroxamic acid in a concentration of about 0.1 to 1.2 wt. %;
c. a hydroxyacetophenone selected from the group consisting of 4-hydroxy-acetophenone, 3-hydroxyacetophenone, 2-hydroxyacetophenone and combinations thereof in a concentration of about 0.1% to 1.0 wt. %; and
d. cycloalkyl compounds
in a total concentration of about 0.5 to 1.0 wt. %.
2. The cosmetic composition of claim 1 , wherein the antimicrobial composition is present in an amount effective to at least inhibit 99% of at least one viable microorganism from re-growth using the modified challenge test at day 21 and further wherein the microrganism is selected from B.cepacia, P.aeruginosa, P.putida, S.aureus, C.albicans and A.brasiliensis or any combination thereof.
3. The cosmetic composition of claim 1 further comprising isothiazolinone antimicrobial compounds; wherein total isothiazolinone antimicrobial compounds are present at a maximum level of 0.15 wt. % as a total amount based on the weight of the cosmetic composition.
4. The cosmetic composition according to claim 1 , wherein the composition is a medicament.
5. The cosmetic composition according to claim 4 wherein the composition is an antimicrobial composition.
6. The cosmetic composition of claim 1 , wherein the antimicrobial composition is present in an amount effective to at least inhibit 99% of viable microorganism B.cepacia from re-growth using the modified challenge test at day 21.
