Description
COMPOSITION OF LIM PIECE AND STERILIZATION AND ITS USE TO STERILIZE AND / OR CLEAN DU RAS SURFACES
Field of the Invention The present invention relates to acidic disinfecting and / or cleaning compositions comprising a specific antimicrobial quaternary system, consisting of C 1 -C 4 hydroxyalkyl carboxylic acids, C 5 -C 8 monocarboxylic acids, C 4 dicarboxylic acids , saturated or unsaturated, substituted or unsubstituted, and additional organic or inorganic acids. The compositions of the present invention can be presented in the form of concentrates and in the form of diluted use solutions. They can be used in a process for sterilizing and / or cleaning hard surfaces, preferably in an on-site cleaning process (CIP) and / or on-site disinfection (SI P) for cleaning and / or disinfecting plants in food industries, dairy, drinks, brewery and soft drinks.
BACKGROUND OF THE INVENTION Periodic cleaning and disinfection in the dairy, food and beverage industries, in food preparation and service businesses, is a necessary practice for product quality and public health. Waste left on equipment surfaces or contaminants found in the process or service environment can promote the development of microorganisms. The protection of the consumer against potential health damages, associated with pathogens or toxins and the maintenance of the quality of the product or service requires the routine removal of residues from surfaces and effective disinfection in order to reduce microbial populations. The visual inspection of the equipment can not ensure that the surfaces are clean or free of microorganisms. Antimicrobial treatments, as well as cleaning treatments, are therefore required for all critical surfaces in order to reduce the population of microbes in order to ensure levels established by public health standards. This process is generally referred to as sterilization. The practice of disinfection is of particular interest in food processing facilities where the cleaning treatment is followed by an antimicrobial treatment applied to all critical surfaces and environmental surfaces in order to reduce the microbial population to safe levels, established by law . A sterilized surface, as defined by the Environmental Protection Agency (EPA), is a consequence of a process or program that contains both an initial cleaning treatment and a subsequent disinfection treatment that must be separated by a potable water rinse. A disinfection treatment applied to a cleaned food contact surface should result in a population reduction of at least 99.999% (5 log) over specified microorganisms, as defined by the "Germicidal and Detergent Sanitizing Actino of Disinfectants", Official Methods of Analysis of the Association of Official Analytical Chemists, paragraph 960.09 and applicable sections, 15th Edition, 1990 (EPA Guideline 91 -2). The antimicrobial efficacy of disinfectant treatments is significantly reduced if the surface is not absolutely free of dirt and other contaminants before the disinfection stage. The presence of residual food dirt and / or mineral deposits inhibits disinfectant treatments by acting as physical barriers that protect microorganisms that lie within the organic or inorganic layer from the microbicide. In addition, chemical interactions between the microbicide and certain contaminants can disrupt the mechanism of microbicide elimination. With the arrival of automated cleaning systems on site
(CIP) and on site disinfection (SIP), the need for disassembly has been reduced and cleaning and disinfection have become much more effective. Nevertheless, modern food industries still rely on disinfectants to compensate for design deficiencies or operational limitations in their cleaning programs and the likelihood of very small residual amounts of organic and inorganic dirt and the remaining biofilms on food contact surfaces after cleaning. In cooperation with these process changes and higher performance expectations, disinfectant treatments must also meet the growing demand for more environmentally friendly, less corrosive, safer compositions. Accordingly, there is a need to improve disinfectant treatments to destroy pathogens and food waste microorganisms resistant to conventional treatments within the food offering, food processing and food service industries. In the disinfection operations have been used various chemicals that exhibit varying degrees of antimicrobial activity. Among these are short chain monocarboxylic acids having less than 20 carbon atoms, quaternary ammonium compounds and hexachlorophene compounds. These compounds have been mixed with various surfactants and water to produce aqueous disinfectant solutions. Halogen-containing disinfectants can be corrosive to metal surfaces of food plants and the quaternary ammonia compounds that have also been used adhere strongly to disinfected surfaces even after copious rinsing and can interfere with desired microbial growth during food processing. , for example, fermentation. On the other hand, a problem associated with the use of short chain monocarboxylic acid disinfectants is the poor dilution phase stability in use, particularly at lower water temperatures, of 0 to 10 ° C. The fatty monocarboxylic acids having alkyl chains containing 5 or more carbon atoms are typically characterized as insoluble in water and can be separated or precipitated from the solution as a gelatinous flocculant. The solubility tends to decrease with the decreasing temperature of the water and to increase with the ionic concentration. In addition, the oil or precipitate can be attached to almost all surfaces to which it is intended to sterilize the disinfectant solution, such as equipment surfaces, leading to the formation of a film on these surfaces over time. The deposited fatty acid film that remains on the surface of the equipment tends to have a higher pH than the disinfectant solution from which it comes, resulting in a significantly decreased biocidal efficacy and, if mixed with food dirt, may result in resulting in a film matrix that has the potential to harbor bacteria, an effect opposite to that desired. In addition, antimicrobial solutions containing these antimicrobial agents are undesirable for use in food equipment cleaning applications. The residual amounts of the acidic disinfectant solutions that remain in the equipment after cleaning can impart unpleasant odors and flavors to the food. Cleaning compositions are difficult to rinse from cleaned surfaces. Greater quantities of water are required to completely remove conventional disinfectant solutions. It has been found that the antimicrobial activity of acidic disinfectant solutions, as defined above, can be increased by acidifying the disinfectant solution to a pH below 5, so that acidic disinfectant solutions of this type are generally used in food, beverages, brewery and other industries such as an on-site cleaning solution (CIP) and / or on-site disinfection (SIP) for processing equipment. Although the currently available acidic disinfectant solutions are effective against gram-negative and gram-positive bacteria, such as Escherichia coli and Staphylococcus aureus, are not as effective on any yeast or mold contamination that may also occur. In many applications, yeast infection control requires a separate solution that can be expensive and time consuming.
Such antimicrobiogenic solutions are generally produced by mixing water and an aqueous concentrate containing antimicrobiological agents, water or other diluents and acids capable of producing a pH below about 5 after dilutions. However, it is clear that such antimicrobial compositions should also exhibit homogeneity and stability of the solution during periods of prolonged storage, in particular, at low temperatures. In order to achieve this, solubilizers or coupling agents are added to the compositions in order to maintain the stability of the solution at elevated acid concentrations at prolonged low temperatures or during repeated freeze / thaw cycles. Such solubilizers are generally surfactant hydrothogens capable of solubilizing the antimicrobial agent in the acidic concentrate which maintains it both in the concentrate and in the diluted antimicrobial solution, suitable for conventional use. For this purpose, various anionic, amphoteric and nonionic ionic surfactants or mixtures thereof have previously been employed in such solutions. However, these solubilizers, when used in antimicrobial compositions, tend to cause undesirable foaming, thus requiring the addition of foam suppressors for the CIP application and the SIP application. Additionally, these solubilizers do not provide stability over a wide range of storage temperatures. Accordingly, there is a need to provide a stable antimicrobial composition that can provide an antimicrobial solution that is equally effective in gram-negative and gram-positive microorganisms and in mold, and the microbial activity of which is neutralized by the hardness of the water and which also provides a low foaming antimicrobial use solution capable of removing intense flavor, for example, of soft drinks and which is less corrosive and more environmentally friendly. It has now surprisingly been found that this need can be met by a specific antimicrobial disinfectant and / or cleaning composition capable of being diluted with a significant amount of a food grade diluent to form a solution of antimicrobial use.

The additional details of the present invention are the following, where it should be considered that the type and quantity of the established components of the composition and of the use solution of the present invention can vary such that the disinfectant and / or cleaning compositions are obtained having the desired characteristics and lead to the desired effects. 1) The quaternary antimicrobial system being one of the essential components of the disinfectant and / or cleaning composition of the present invention comprises: a C1-C hydroxyalkyl carboxylic acid, preferably a hydroxyalkyl carboxylic acid a-Ci to C. Examples of suitable hydroxyalkyl carboxylic acids include, but are not limited to, hydroxypropanoic acid, dihydroxy propanoic acid, citric acid hydroxy, hydroxy butyric acid, tartaric acid, glycolic acid, lactic acid and mixtures thereof; a C5 to C18 alkyl monocarboxylic acid, preferably a C6 to C2 alkyl monocarboxylic acid.

The acid used must be compatible with the other components of the disinfectant solution, that is, it must not include instability or cause undue degradation of a surfactant or organic acids. This acid can be either a weak organic acid, such as formic acid, acetic acid, citric acid, tartaric acid, maleic acid, fumaric acid or mixtures thereof or a stronger organic acid, such as alkylsulfonic acid, preferably methylsulfonic acid or an inorganic acid such as phosphoric acid, sulfuric acid, nitric acid (preferably in combination with a small amount (about 1% by weight) of urea to prevent the formation of NOx), hydrochloric acid, sulfamic acid or mixtures thereof. Preferably, phosphoric acid, nitric acid, sulfuric acid and methylsulfonic acid are used. 2) The solubilizer used in the present invention is a surfactant hydrotrope capable of solubilizing the alkyl monocarboxylic acid and the dicarboxylic acid in an acidic diluent while maintaining the monocarboxylic acid and the dicarboxylic acid in solubilized form both in the composition and in the solution of Diluted use of the product under conditions of use. Various anionic, amphoteric and non-ionic ionic surfactants or mixtures thereof can be used in the present invention. Examples of the anionic surfactants that can be used in the present invention are alkyl sulfonates and alkylaryl sulfonates having from about 8 to about 22 carbon atoms in the alkyl portion, as well as the alkali metal salts thereof. Sodium and potassium salts of linear alkylsulfonates, such as sodium laurylsulfonate and potassium alkylbenzene sulfonates, such as sodium xylene sulfonate, sodium cumene sulphonate, sodium toluene sulfonate are commercially important. Amphoteric ionic surfactants are the alkyl imidazolines and alkylamines marketed under the trademark MI RAPON by Miranol. Examples of nonionic surfactants that can be used in the compositions of this invention are the ethylene oxide adducts and propylene oxide adducts of C8 to C22 primary alkanols, sold commercially under the Berol trademarks by Akzo Nobel or Lutensol by BASF, and the ethoxylated and propoxylated types sold under the Plurafac trademarks by BASF. The diluent that can be used is preferably potable water. However, other compatible food grade diluents, such as C2 to C5 alkanols, can also be used.
Additionally, the composition of the present invention may optionally include at least one anionic and / or nonionic surfactant. In some embodiments, a non-ionic surfactant is suitably used to improve surface wetting, removal of dirt, etc. It can also work to improve the solubility of the fatty acids used in dilutions of use.
The composition of the present invention is, as already mentioned, capable of forming a use solution by mixing the composition with a diluent, such as water. The use solution obtained generally comprises: a) from about 1 to about 1 000 parts per million (ppm) of the defined hydroxyalkyl carboxylic acid, b) from about 1 to about 1000 ppm of the C5-C alkyl monocarboxylic acid? 8 defined, c) from about 1 to about 1000 ppm of the defined dicarboxylic acid, d) an organic or inorganic acid, as defined above, in an amount sufficient to produce a pH of the use solution of about < 5.0, preferably 4.5 to 1.0, e) from about 10 to about 1000 ppm of a solubilizer, as defined above, f) water as the remainder, of the composition and g) optionally at least one anionic or non-ionic detergent to improve the wetting of the surface, removal of dirt, etc. The antimicrobial disinfectant composition of the present invention can be successfully employed to disinfect and / or sterilize fixed food processing facilities at a location, such as those of dairy plants, breweries and beverages. The composition of the present invention exhibits an antimicrobial activity at a temperature of from about 0 ° C to 80 ° C. To carry out the disinfection, the diluted use solution having a temperature from 0 to 80 ° C, preferably from 5 to 60 ° C, is recycled through the system for a sufficient period of time to contact and eliminate the undesirable microorganisms . This time can be any from less than 30 seconds to approximately 10 or 20 minutes, depending on the type and amount of contamination present. Preferably, the contact time will be in the range of from about 1 to about 5 minutes. After disinfection, the composition is drained from the system and the system is rinsed with potable water. In most on-site cleaning applications, the system can be returned to operation immediately after removal of the disinfectant solution. However, the system can also be rinsed with potable water or any other suitable material after disinfection.
The disinfectant composition can be mixed with a detergent composition to impart the additional disinfectant properties of this invention to a detergent when in use. For example, detergents are routinely used in European countries to clean various facilities in food, dairy, brewery and beverage plants, in order to avoid the need for a subsequent disinfecting rinse of the facility. The disinfectant composition of the invention can also be used in other ways, such as in lane lubricants, nipple chemical solutions and washing machine rinse aids. When the disinfectant composition is used in a detergent composition, suitable surfactants are used which are preferably those of the low foaming, anionic or non-ionic type. It is clear that such a surfactant has to be compatible with the disinfectant composition in order to avoid degradation or separation in the final product. For a more complete understanding of the present invention, reference should be made to the following examples. The examples should only be considered illustrative and not limiting to the present invention. All percentages are in "% by weight".
EXAMPLES Preparation of the compositions Each of the following compositions was prepared by mixing the ingredients listed in the following table 1 in sequential order, mixing thoroughly by stirring and allowing each ingredient to disperse or dissolve completely in the liquid mixture before mixing. addition of the next ingredient. The resulting compositions were clear and homogeneously uniform after mixing all the listed ingredients. Compositions A1 to A4 contained the quaternary antimicrobial system of the present invention. Composition B1 is a comparative acidic composition, corresponding to a prior art, represented by compositions currently commercially available for standard CCI P applications. Table 1
Test Methods 1. Biocidal Efficacy Test The quantitative suspension examination for the evaluation of bactericidal and fungicidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas was conducted in accordance with EN 1276: 1997 (bacteria) and EN 1650: 1997 (mushrooms), (C EN - European Committee for Standardization). The tests were conducted with 0.25, 0.50, 1.00 and 4.00% of use solutions prepared from the compositions of Table 1 by diluting them with water in an amount sufficient to obtain each of the solutions for use, for example, by mixture of 4 g of composition A1 with 96 g of water to obtain 4% by weight of the solution of use A1. For dilution, sterile hard water, standardized, with 300 mg / kg CaCO3 was used. The samples were exposed at 20 ° C to the bacteria by eliminating Lactobacillus brevis, the yeast Saccharomyces diastaticus and the mold Aspergillus niger. The resulting data are presented in Table 2. As can be seen from the data in Table 2, compositions A1 to A4 of the present invention containing the quaternary microbiocidal system show a higher, significant microbiocidal activity than the comparative composition. B1, which corresponds to the currently commercially available compositions for CIP standard in the industry. Even with half the amount of octanoic acid (A3 and A4) or one third of the amount of N-octenyl succinic acid (A2, A3 and A4), compositions A1 to A4 of the present invention provide the same or better rates of reduction of microorganisms compared to the comparative composition B1 under identical test conditions. It is notable, in particular, that compositions A1 to A4 provided a 99% reduction for A. Niger with 4% use solutions, which is the upper economic limit for a use solution while comparative composition B 1 failure. Table 2
2. Foaming Evaluation 2 liters of a 1% use solution were recycled with a flow rate of 1.8 liters per second through a tempered 5.5 I glass cylinder for 30 min in order to establish a foam / liquid balance . The formation of the foam layer in cm was determined immediately at the end of a pumping period of 30 min ("0") and 15 sec after the pump was switched off ("1 5").
Table 3
The above data clearly shows that the quaternary system of the invention leads to less or no foam, which is necessary for a CIP and / or SIP application compared to the composition B 1 representing the compositions currently commercially available for CI P applications and SIP standards.
3. Phase Separation Test (Stability) Using the compositions in Table 1, use solutions were prepared at 0.5%, 1%, 2% and 3%, as explained above and after conditioning at 20 ° C during 3 days were visually inspected for physical instability. "+" means stability (without phase separation); "-" means instability (discernible phase separation).
Due to the possibility of reducing the amounts of microbiocidal agents (octanoic acid and N-octenyl succinic acid), the risk of phase separation according to the present invention is clearly lower. Therefore, the major concentrated use solutions for CIP and SIP applications are usable without risk of leaving residues in the treated plant.
