- Typical activators include mineral acids, such as sulphuric acid, hydrochloric acid, nitric acid, and phosphoric acid or a mixture thereof. Regarding mineral acids, hydrochloric acid is a stronger catalyser than nitric acid.

- the composition according to the invention comprises an antimicrobic substance that is preferably absorbed in the corpuscular substance.
- Particularly good preservative fluids include those that are easy to handle by dispensing devices, such as granular mineral absorbents, including moler earth, and lumpy celluloses.
- Solic compositions are thus prepared by absorbing a composition in liquid form as such in a large-area inorganic or organic absorbent, such as silica, clay mineral, or cellulose or mixtures thereof.
- Solid compositions may also be prepared so that its liquid ingredients or liquid compositions of the ingredients are separately absorbed in similar or different absorbents, which are finally mixed together. At the same time, other possible solid ingredients may be added.
- the composition according to a particularly preferred embodiment of the invention is in a solid particle-like form so that the mineral acids and other possible compositions that unstabilize formic acid or the ester of the unsubstituted or substituted benzoic acid are situated in different particles than the formic acid and the said benzoic acid esters.
- the antimicrobic substance is absorbed in the first part of the corpuscular substance, and the substance that accelerates the hydrolysis of the ester of the unsubstituted or the substituted benzoic acid is absorbed in the second part of the corpuscular substance.

- This preferred embodiment also comprises the advantageous components and parametric relations which are presented above separately.
- the invention is related to the use of any of the compositions described above as a substance inhibiting the growth of hazardous microbes, such as .Salmonella, in forage material and forage products and the like.
- the composition may also be used to preserve green forage or grain, to improve the hygiene of cattle sheds and the like, or to disinfect devices, equipment, and packages.
- Example 2 A test was conducted as in the previous example but using another forage sample. The following results were obtained:
- Example 3 SALMONELLA
- the Salmonella infantis used in the test had originally been isolated from a chicken and cultivated in buffered peptone water.
- sets of dilution were made in peptone water by using different amounts of preservatives.
- the growth of bacteria was observed by a Bioscreen device (Labsystems, Finland). The device automatically measures, from the set of samples, the cloudiness that depicts bacterial growth as a function of time.
- Figs. 1 acetic acid
- 2 acetic acid with 2.5 weight-% of EB and 2.5 weight-% of propyl formate
- composition weight fractions
- both acids activate the decomposition of both the ester and the formic acid.
- hydrochloric acid was used, a considerable amount of carbon monoxide gas had formed already during one week in an incubator, and the amount of benzoic acid was so large that some of it had crystallized.
- This composition that is rich in hydrochloric acid is thus suitable to be used only when no preservation time is required of the product.
- Example 4A The test of Example 4A was repeated so that propyl benzoate was used instead of ethyl benzoate.
- the amount of propyl benzoate in the sample containing sulphuric acid was 1.68 weight fractions, and 0.14 weight fractions in the sample containing hydrochloric acid. Both solutions remained clear.
- Liquid mixtures were absorbed in a solid absorbent according to the next table.
- the obtained products were packed in impermeable bottles which were kept in increased temperatures.
- the amount of carbon monoxide generated as a breakdown product of the formic acid was analyzed from the gas phase of the bottles by using gas chromatograph. The following results were obtained:
- Damolin was the same as the one used in the previous example.
- Zeothix 265 is a precipitated silicic acid (Huber Corporation).
- the cellulose was commercial sheet cellulose which was used to make pieces of about 1mm x 1mm by shredding it first with a shredder to form strips, which were then fed in transversally and, finally, oversized pieces were screened out.
- Mixture 7/1 was granular and easy to process.
- Mixture 7/2 felt dry but did not flow as easily as the former mixture.
- Mixture 7/3 was fine and dry, but vault-fo ⁇ ning, and thus more difficult to dispense.
- Mixture 7/4 maintained its block-like form and remained relatively easy to process, even though it felt damp.
- the hardness of its pieces could be further improved by powdering the mixture with small amounts of a salt-like substance which form a slightly soluble formiate such as calcium or magnesium formiates.
- a salt-like substance which form a slightly soluble formiate
- Such substances include, e.g., finely powdered calcium chloride, calcium carbonate, dolomite, and calcium sulphate.
- 60 parts by weight of a granular absorbent was mixed with 40 parts by weight of a mixture of strong formic acid, sulphuric acid, and ethyl benzoate in a ratio of 85: 10:5.
- Another mixture was made with a similar approximate composition by mixing together a) 90 parts by weight of a mixture containing 60 weight-% of the absorbent and 40 weight-% of a mixture of formic acid and ethyl benzoate in a ratio of 94.4:5.6. and b) 10 parts by weight of a mixture containing 40 weight-% of sulphuric acid and 60 weight-% of the absorbent.
- compositions according to the following table were prepared:
- FA(EB) a mixture with 93.9 parts by weight of formic acid and 4.1 parts by weight of ethyl benzoate, and 0.03 parts by weight of benzoic acid.
