Abstract

The present disclosure relates to the field of antimicrobial compositions. More specifically, the present invention relates to the use of a composition comprising a component selected from the group consisting of (i) nonyl-2, 6-dien-1-ol and at least one component selected from the group consisting of 3-neopentylpyridine, 2-methylhex-3-ketoxime, terpilenol, and 2-isopropyl-5-methylphenol, as an antimicrobial agent, and to the use of a composition comprising a component selected from the group consisting of: (i) nonyl-2, 6-dien-1-ol and at least one component selected from the group consisting of 3-neopentylpyridine, 2-methylhex-3-ketoxime, terpilenol, and 2-isopropyl-5-methylphenol; (ii) at least one component selected from the group consisting of [gamma]-dodecalactone, 1-methyl-4-(1-methylvinyl)-cyclohexene, 4-methoxybenzaldehyde, and 1, 3-benzodioxol-5-formaldehyde, and at least one component selected from the group consisting of [gamma]-dodecalactone, 1-methyl-4-(1-methylvinyl)-cyclohexene, 4-methoxybenzaldehyde, and 1, 3-benzodioxol-5-formaldehyde; (iii) (Z)-3, 7-dimethyl-2, 6-octadiene-1-ol, and [gamma]-dodecalactone, and a method for preparing the same; (iv) cis-4-(isopropyl) cyclohexane methanol and 4-methoxybenzaldehyde, and (v) an organic solvent; and (v) 1, 3-benzodioxol-5-formaldehyde and 4-methoxybenzaldehyde, where the ingredient is present in an amount sufficient to provide an antimicrobial effect. The composition and its use for the preparation of antimicrobial active perfuming compositions and consumer products are also an object of the invention.

[0171] Methods for Assessing Antimicrobial Activity

[0172] The following methods allow for a combined assessment of the antimicrobial activity of different raw materials. The fractional inhibitory concentration index (FIC index) is a measure of activity (Garcia L.S., Clinical Microbiology Procedures Handbook, pg. 140-162, 3 rd Edition (2010), ASM Press, Washington DC), and calculated according to the following formula:

[0173]

[0174] of which (MIC A individually) and (MIC B alone) are the minimum inhibitory concentrations (MIC) of components A and B when used alone; while (MIC A combination) and (MIC B combination) is the minimum inhibitory concentration of materials A and B when tested in combination. Component A corresponds to non-2,6-dien-1-ol and component B represents 3-neopentylpyridine, 2-methylhex-3-one oxime, terpineol or 2-isopropyl-5- methylphenol.

[0222] Preparation of bacterial solutions

[0223] Bacterial solutions of the two strains E. coli DSMZ 1103 and S. aureus DSMZ 1104 were prepared for BCT testing as follows. Stock cultures stored at -80°C were subcultured on Tryptic Soy Agar (TSA) agar plates and incubated at 37°C for 24 hours to obtain single colonies. Single colonies of primary cultures were streaked onto TSA slants and incubated in a 37°C incubator for 24 hours. Collect bacterial plateaus of slant cultures in PBS buffer to prepare target levels of 1–5 × 10 8 CFU / mL suspension. A 1:100 dilution of each cell suspension in PBS buffer was used as the bacterial solution for the BCT test.

Primary cultures were subcultured onto TSA-TW80 again to prepare secondary cultures. A single colony of the secondary culture was inoculated into 30 ml of brain heart infusion (BHI) broth (BHI-TW80) containing 0.5% Tween 80 and incubated at 37°C for 24 hours at 180 rpm. An aliquot (1 ml) of the 24 hour culture was inoculated into 30 ml of fresh BHI-TW80 broth and incubated for 48 hours at 37°C at 180 rpm. Aliquots (2-3 ml) of the 48 hour culture were inoculated into four 50 ml fresh BHI-TW80 broth media and incubated at 37°C at 180 rpm for 4-6 hours. When the OD reached the ...
