Description:
ANTIMICROBIAL NATURAL COMPOSITIONS

TECHNOLOGICAL FIELD

The present disclosure generally concerns antimicrobial natural compositions that are based on combinations of extracts, e.g. plant extracts.

BACKGROUND

Public concern about the safety of synthetic preservatives used in cosmetic and foods, especially regarding their accumulation and subsequent health effect, have driven health authorities to reduce the applied concentrations or even ban synthetic preservatives. Alternatives such as plant antimicrobial substances are in the focus of many researches, however due to low potency, narrow range and high prices, they are rarely used to replace synthetic preservatives.

DETAILED DESCRIPTION OF EMBODIMENTS

Example 1: Composition of saponin extract, Styrax extract and maltol in cream formulation

A Preservatives Effectiveness Test (PET) was carried out for various combinations of saponin extract obtained from Sapindus mukorossi. Styrax extract (Sumatra benzoin) and maltol (obtained from fermented wheat) for evaluating the synergistic antimicrobial effect therebetween. The antimicrobial efficiency was tested in accordance with current ISO 11930 requirements. The test consists of challenging a reference cream lotion with a prescribed inoculum of suitable microorganisms. The tested microorganisms used for the PET are detailed in Table 1. Table 1: Tested microorganisms

Each sample was inoculated at time “0” and mixed with one of the microbial suspensions using a ratio-equivalent to 1% inoculum to product (200 pl inoculum into 20 g sample). The concentrations of test microorganisms added to the cream were such that the concentration in the cream immediately after inoculation was between 1 x 10 5 - 1 x 10 6 CFU/g for bacteria and 1 x 10) 4 - 1 x 10 5 CFU/g for molds.

Samples were stored at 20-25°C. The samples were sampled in intervals of 7, 14 and 28 days. At each time interval, 0.5 g of the sample was diluted 1 : 10 in TAT (neutralizer buffer). 100 pl of each diluted sample was seeded using the Pour Plate method on TSA plates for bacteria and on SDA plates for the fungi. Each plating was done in duplicates. For A. brasiliensis at Day 7 only, a second dilution of 1 : 10 was prepared in TAT before seeding (for a total of 1 : 100 dilution).

The number of viable microorganisms/g in the mixture at each test interval was determined by the Pour Plate Count Method. The TSA plates were incubated at 30-35°C for 3-5 days unless a reliable count was obtained in a shorter time. The SDA plates were incubated at 20-25°C for 5-7 days or less if reliable count was obtained prompter.

The counts obtained in all countable dilutions were used to calculate the mean value of CFU, per gram product/challenge microorganism/ time interval. Using the calculated concentration of microorganisms in the initial inoculum per gram present as a baseline, the change in log 10 values of the concentration of the CFU/g was calculated for each time interval and the changes were expressed in terms of log reduction.

Log reduction results are provided in Table 2. In the Tables below, AB, CA, PA, EC and SA indicate A. brasilliensis. C. albicans, P. aeruginosa, E. coli and S. aureus, respectively. Table 2: Summary of results for saponin extract (SN), Styrax extract (BZ) and maltol (ML) combinations, log reduction from initial inoculation

For P. aeruginosa, a synergistic effect of the SN/BZ/ML combination was seen at 0.2wt% maltol combined with 0.75wt% saponin extract and 0.25wt% Styrax extract. For A. brasilliensis, a synergistic effect of the combination was seen at 0. 04wt% maltol combined with 0.15wt% saponin extract and 0.05wt% Styrax extract. For C. albicans, a synergistic effect was seen at 0.04wt% maltol combined with 0.15wt% saponin extract and 0.05wt% Styrax extract.

Example 2: Composition of saponin extract, Styrax extract, maltol and citric acid in cream formulation

A Preservatives Effectiveness Test (PET) was carried out for various combinations of saponin extract from Sapindus mukorossi, Styrax extract (Sumatra benzoin), maltol (obtained from fermented wheat) and citric acid as an additive. The test was carried out similarly to Example 1. Log reduction results are provided in Table 3. Table 3: Summary of results for saponin extract (SN), Styrax extract (BZ), maltol (ML) and citric acid (cit) combinations, log reduction from initial inoculation

For C. albicans, a synergistic effect of the combination was seen at 0.04wt% maltol combined with 0.075wt% saponin extract, 0.025wt% Styrax extract and 0.003 wt% citric acid. For S. aureus, a synergistic effect of the combination was seen at 0.02wt% maltol combined with 0.0375wt% saponin extract, 0.0125wt% Styrax extract and 0.0015 wt% citric acid.

Example 3: Composition of saponin and Styrax extracts, with maltol as an additional plant extract in agar dilution test, with and without citric acid

An agar dilution test was carried out for various combinations of saponin extract (Sapindus mukorossi) and Styrax extract (Sumatra benzoin), with maltol extracted from wheat as an additional plant extract, for evaluating the synergistic antimicrobial effect therebetween.

The agar dilution test was carried out as follows: TSA (tryptic soy agar) or SDA (Sabouraud dextrose agar) media were melted at 99±2°Cand kept warm until seeding (43±2°C). Into a quota of the growth medium, the maltol and extract were added and stirred. 5ml of the mixture was poured into each test plate and left to cool and solidify. The plates were then inoculated by defined amounts of test microorganisms (E. co/i, S. aureus and P. aeruginosa used on TSA plates, C. albicans and A. brasilliensis used on the SDA plates). The plates were incubated at 25-35°C for 24-48 hours and then assessed for microorganisms’ growth. The agar dilution test provides test results which are independent of the formulation (e.g. cosmetic formulation) into which the composition is to be incorporated, hence can be used as a good basis for comparing activity of the compositions.

The test results for the combinations of saponin and Styrax extracts with maltol are detailed in Table 4, while the results for the compositions of saponin and Styrax extracts with maltol and citric acid are shown in Table 5. (+) indicates growth, (+/-) indicates partial growth, while (-) indicates no growth. Positive control was obtained by utilizing a commercial preservative.

SUBSTITUTE SHEET (RULE 26) As can be seen, a composition of 0.2 wt% maltol, 0.025% benzoin and 0.075% saponin extract showed antimicrobial activity against all tested microorganisms. For A. coli, a clear synergistic effect can be observed for a composition of 0.15 wt% maltol, 0.05 wt% benzoin and 0.15 wt% saponin extract; A. brasiliensis a synergistic effect can be observed for a composition of 0.15 wt% maltol, 0.025 wt% benzoin and 0.08 wt% saponin extract; while for both C. Albicans and S. aureus a clear synergistic effect is demonstrated already for a composition of 0.04 wt% maltol, 0.025 wt% benzoin and 0.075 wt% saponin.

Table 5: Agar dilution test results for compositions of saponin (SN) and Styrax (BZ) extracts with maltol (ML) and citric acid (CIT) (amounts in wt%)

As can be seen, a composition of 0.2 wt% maltol, 0.125% benzoin, 0.375% saponin extract and 0.015 wt% citric acid showed antimicrobial activity against all tested microorganisms. For P. aeruginosa, a clear synergistic effect can be observed for a composition of 0.08 wt% maltol, 0.025 wt% benzoin, 0.075 wt% saponin extract, and

SUBSTITUTE SHEET (RULE 26) 0.015 wt% citric acid; while for S. aureus a synergistic effect is demonstrated for a composition of 0.075 wt% maltol, 0.05 wt% benzoin, 0.15 wt% saponin extract and 0.015 wt% citric acid.

Example 4: Composition of saponin extract, Styrax extract (benzoin extract), and additional plant extracts in agar dilution test

An agar dilution test was carried out for various combinations of saponin extract (Sapindus mukorossi) and Styrax extract (Sumatra benzoin), with various additional plant extracts, for evaluating the synergistic antimicrobial effect therebetween. The test protocol was as in Example 3.

The tested extracts were Malpighia emarginata (acerola) fruit extract, Thymus vulgaris (thyme) leaves extract, Origanum vulgare leaves (oregano) extract, Syzygium aromaticum (clove) bud oil, Nigella sativa seeds extract, Pimenta dioica fruit (allspice) extract, Magnolia officinalis bark extract, Cymbopogon citratus (lemongrass) leaves extract, and Paeonia lactiflora extract.

The test results are detailed in Table 6. (+) indicates growth, (+/-) indicates partial growth, while (-) indicates no growth. Positive control was obtained by utilizing a commercial preservative.

Table 6: Agar dilution test results for compositions of saponin and Styrax extracts and various extracts (amounts in wt%)

As can be seen, a composition of 0.075 wt% saponin and styrax 0.025 wt% with Allspice extract 0.2 wt% showed synergism in antimicrobial activity against E. coli and partially for A. brasiliensis . For compositions including 0.2 wt% Magnolia extract, synergism was observed against A. brasiliensis. For compositions including 0.2 wt% Lemongrass extract, synergism was seen against C. albicans, S. aureus and A. brasiliensis. When comprising 0.2 wt% of Paeonia extract, synergism was observed in antimicrobial activity against C. albicans and A. brasiliensis.

Example 5: Delayed antimicrobial activity

A Preservatives Effectiveness Test (PET) was carried out for two compositions: composition 5A that contained 0.2 wt% maltol, 0.05 wt% Styrax extract (Sumatra benzoin) and 0.15 wt% saponin extract (Sapindus miikorossi). and composition 5B that contained 0.2 wt% maltol, 0.125 wt% Styrax extract (Sumatra benzoin), 0.375 wt% saponin extract (Sapindus miikorossi). and 0.015 wt% citric acid. The tests were carried out according to the protocol of Example 1, however inoculated with 5 x 10 6 CFU/ml of S. aureus (SA), 5 x 10 6 CFU/ml of S. epidermis (SE) and a 6.3 x 10 6 CFU/ml mixture of both. These microorganisms are indicative of microorganisms residing naturally on the skin and are part of the desired microbiota of the skin. The log reduction was recorded for various test points, as shown in Table 7.

Table 7: Summary of results for compositions 5A and 5B, log reduction from initial inoculation, in cream formulation

As can be seen, no reduction in microbial population was observed for the first 48 hours in creams that contained compositions 5A and 5B, indicating that only after 48 hours the natural microbiota of the skin is expected to be affected. However, for the synthetically preserved cream, elimination of microbiota is clearly observable starting from several hours after exposure. Thus, the maltol/saponin/Styrax composition (with and without citric acid), unlike the synthetic preservative, is not expected to hinder the natural microbiota for the time period that the formulation normally resides on the skin (several hours), however, as show in Examples 1-3 above, provides antimicrobial activity against the undesired microorganism in the cream. This delayed effect is also demonstrated in Figs. 1 A-1D, which are pictures of an agar plate inoculated with a mixture of S. aureus, S. capitis, S. epidermis and S. hominis, taken after 7 hours of incubation. The mixture of microorganisms represents the natural skin microbiota. Fig. 1A shows a sample of cream without any preservatives. Fig. IB shows a sample of the cream in which the bottom half of the sample contained a commercial synthetic preservative (ethylhexyl glycerin 1%) and the upper half did not contain a preservative - showing almost complete elimination of the microbiota in the preserved region. In comparison, Figs. 1C and ID show samples of the cream with the bottom half of the sample containing the compositions 5A and 5B, respectively, and without preservative in the upper half. Contrary to the commercial preservative, it can be seen that in compositions 5A and 5B, no harm to the natural microbiota is observed, indicating the antimicrobial delayed effect of compositions of the disclosure.
