- Examples 3 and 4 Other examples of composition according to the invention for a foaming application
- Examples 5 and 6 Other examples of composition according to the invention for a non-foaming application
- compositions will be used after dilution at concentrations of between 0.5 and 3.0%, ie between 5 and 30 g/L for use on an open surface or closed circuit.
- concentrations between 0.5 and 3.0%, ie between 5 and 30 g/L for use on an open surface or closed circuit.
- the degree of dilution will depend on the material used and the concentration (V/V) of active ingredients necessary to obtain a satisfactory result from a microbiological point of view.
- EN 1276 Chemical antiseptics and disinfectants - Quantitative suspension test for the evaluation of the bactericidal activity of chemical antiseptics and disinfectants used in the food industry, in industry, in domestic and community areas - Test method and requirements (phase 2, step 1 ).
- EN 1650 Chemical antiseptics and disinfectants - Quantitative suspension test for the evaluation of the fungicidal or yeasticidal activity of chemical antiseptics and disinfectants used in the food industry, in industry, in the domestic and in the community - Test method and requirements (phase 2, step 1) - Chemical antiseptics and disinfectants - Quantitative suspension test for the evaluation of the fungicidal or yeasticidal activity of chemical antiseptics and disinfectants used in the field of agri-food, in industry, in domestic and community areas
- EN 13697 Chemical antiseptics and disinfectants - Quantitative non-porous surface test for the evaluation of the bactericidal and/or fungicidal activity of chemical disinfectants used in the food industry, in industry, in the fields domestic and community - Test method without mechanical action and requirements (phase 2/step 2).
- Example 1 The composition of Example 1 was thus evaluated and the following results were obtained:
- composition of Example 1 exhibits bactericidal efficacy for a concentration of 0.5% (V/V) and a contact time of 15 minutes, at a temperature of 20° C., as well as yeasticidal efficacy for a concentration of 2.0% (V/V) and a contact time of 15 minutes, at a temperature of 20°C.
- the compositions according to the invention exhibit bactericidal and yeasticidal efficacy for a concentration greater than or equal to 2% (V/V).
- compositions according to the invention were prepared by varying the concentration
- compositions were diluted in demineralized water at 20° C.; the pH of the dilute solution thus obtained was measured for different dilutions, expressed as the amount of dry matter of the composition concentrated in IL of the dilute composition.
- the pKa of octanoic acid is 4.85 (25° C.).
- the drop in pH on dilution makes it possible to find octanoic acid in its predominant acid form, which in the case sought, increases its disinfecting properties.
- the disinfectant compositions can be more or less corrosive with respect to the substrates on which they are applied, and in particular those formed from steel alloys stainless steel or aluminum that are usually found in the food industry. This corrosion results in a uniform dissolution of the metal surface in contact with the applied composition. It is generally evaluated by measurements of mass loss or reduction in thickness of the metal at the surface of the substrate to which the composition is applied and is expressed by a corrosion rate (mg or g per unit area and time) or more often by a corrosion rate (decrease in thickness per unit of time: mm/year).
- Vcorr corrosion rate (cm/year)
- the corrosivity of a composition is determined according to the following evaluation grid;
- compositions according to the invention were evaluated under the following experimental conditions:
- Aluminum coupon reference Supplier: Etalon - Ref: AE025100AA Stainless steel 304L coupon reference: Supplier: Imotron - Ref: C01011450104100
- Example 1 of the invention leads to very low corrosion of stainless steel alloys and aluminum alloys for a concentration (m / V) of 3%, higher than the usual conditions of 'use.
