Definitions
- composition containing glycolipids and preservatives
- the invention relates to compositions containing glycolipids and benzoic acid and / or sorbic acid.
- Preservatives are used to protect various products from microbial attack and spoilage. In recent years, a number of preservatives have fallen into disrepute because of toxicological concerns, and their use has been partially limited by law.
- Preservatives that are not affected, but have other disadvantages, e.g. they are effective only within a limited pH range, or they are not effective over the full spectrum of microorganisms. In this respect, a safe preservation of e.g.
- Benzoic acid, sorbic acid and their salts are among the preservatives still approved in many applications and regarded as toxicologically harmless.
- these have the disadvantage that they have sufficient activity only in the acidic range in protonated form.
- a clear effect in a practice-relevant concentration range is obtained only at pH ⁇ 5.5.
- they have a burning, unpleasant taste (Otero-Losada, M. 1999 - Kinetic study on benzoic acid pungency), so that their use concentration and thus their effectiveness in food and dental care products is limited.
- Glycolipids are glycosidically linked to sugars lipids.
- rhamnolipids and sophorolipids (SL) are counted, which can be prepared for example by means of microbial fermentation.
- An antimicrobial effect is described but limited to certain organisms, in particular Gram-positive bacteria.
- no antimicrobial effect of rhamnolipids on Eschericia coli NCTC 10418 and Pseudomonas aeruginose PA01 could be detected while Bacillus subtilis NCTC 10400 was inhibited.
- sophorolipids good activity could be demonstrated on various Gram-positive bacteria, but not on E. coli (Kapjung, K. et al., Characteristics of Sophorolipids as to Antimicrobial Agent, Journal of Microbiology and Biotechnology, Volume 12, Issue 2, 2002, pp.235-241). About the taste profile of this
- Glycolipids is not known.
- the object of the invention was to increase the antimicrobial efficacy of benzoic and sorbic acid and their salts in the range of pH> 5.5 and at the same time to reduce the unpleasant taste impression of these preservatives.
- glycolipids to benzoic acid and / or sorbic acid largely neutralizes the unpleasant taste of these acids.
- the pH range in which these preservatives are effective could be extended. While neither benzoic acid / sorbic acid nor glycolipids used in the
- the invention relates to compositions containing benzoic acid and / or sorbic acid and glycolipids.
- An advantage of the present invention is that these preservatives can be used in the corresponding mixtures in a wider pH range and product range.
- they can be used to improve the taste and microbiological stabilization of dental care products such as mouthwashes and toothpastes, but also for the stabilization and taste improvement of care products (bath additives, lipstick, etc.).
- dental care products such as mouthwashes and toothpastes
- stabilization and taste improvement of care products bath additives, lipstick, etc.
- Another advantage is that it requires less perfuming or flavoring to mask the unpleasant taste.
- Another advantage is that it can also preserve products that are not stable in a lower pH range. Yet another advantage is that the amount of preservative needed can be reduced.
- At least one glycolipid preferably selected from the group of rhamnolipids and sophorolipids, especially rhamnolipids and
- weight percentages are based on the total composition, characterized in that the pH of the composition at 25 ° C in a range of 3.5 to 9, preferably from 5.6 to 7, more preferably from 5.6 to 6.6, is located.

- compositions according to the invention are used as preservatives for foods, cosmetic products,
- Example 1 Taste masking of benzoic acid and sorbic acid by addition of rhamnolipids
- the proportion of rhamnolipids and their salts was> 90% by weight, based on the dry matter.
- Ratios to the acid form which is quantified in the HPLC analysis.
- Table 1 Composition of the rhamnolipids used. Data in% by weight of the respective congener (as acid form) related to the sum of all rhamnolipids (as acid form). diRL-C8C10 15.8
- the protein content was determined by the bicinchoninic acid photometric assay (BCA Assay, ThermaFisher Scientific) and was ⁇ 1% by weight based on the dry weight of the rhamnolipid.
- Example 2 Synergistic action of rhamnolipids and benzoic acid, or sorbic acid
- compositions Prepared compositions and the pH adjusted to 5.8.
- Table 3 Compositions for germ load tests (data in% by weight, remainder water)
- compositions of Table 3 were inoculated with a defined number of microorganisms of various microorganisms and the inoculated samples at
- the microorganisms used for the microbial load tests were Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans and Aspergillus brasiliensis.
- Potassium benzoate (M7) had practically no effect at this pH, the germ count was not reduced.
- Potassium sorbate (M9) had little effect.
- the combination of potassium benzoate and sorbate (M12), or rhamnolipids alone (M1 1) had little effect. In particular, the number of bacteria on yeasts and fungi was not significantly reduced.
- Table 4 Compositions for germ load tests (data in% by weight, remainder water)
- microorganisms used for the microbial load tests were Candida albicans and Aspergillus brasiliensis. The results are shown in Figures 1 and 2 and show a synergistic effect of the two components.
- Example 3 Synergistic effect of sophorolipids with a mixture of benzoic acid and sorbic acid
- a commercial sophorolipid (Rewoferm® SL446) was diluted to a sophorolipid content of 10%.
- an aqueous solution of 0.1% sorbic acid and 0.1% benzoic acid were prepared and the pH was adjusted to 6.2. Subsequently, the three samples were subjected to a microbial load test with Aspergillus brasiliensis as described in Example 2. Only in the combination of sophorolipid with preservatives was a clear
- Example 4 Synergistic action of rhamnolipids with a mixture of benzoic acid and sorbic acid
- the minimum inhibitory concentrations were determined according to the microdilution method on the basis of DIN58940-8 for various compositions with respect to Candida albicans.
- Candida albicans DSM1386 was transferred from the stock culture to a Sab. Agar plate inoculated and incubated at 30 ° C for two days. From this Vorzucht a Sab.-Schrägagarrschreibchen was inoculated and again incubated for two days at 30 ° C.
- the slants were washed off with seven ml of Mueller-Hinton broth pH 6, and the washed-up germinal suspensions in 100 ml flasks were filled with 5 g of glass beads and incubated for 3 min. placed on the rotary shaker.
- the exact germ count of the inoculum was determined by means of the Spiralometer.
- the minimum inhibitory concentration was determined.
- MIC minimum inhibitory concentration
