    Composition and method to control and eliminate the formation of biofilms on surfaces. The invention relates to a detergent composition comprising, in defined amounts in the memory: at least one anionic surfactant; at least one nonionic surfactant; a mixture of at least one glycol and at least one alcohol; at least one metal ion sequestrant; a combination of enzymes comprising at least one protease, at least one lipase, at least one amylase and at least one enzyme selected from cellulase and pectin lyase; at least one essential oil; at least one essential oil fixing agent; a pH regulating agent; and a means of dissolution. In addition to a method for controlling and eliminating the formation of biofilms on surfaces by application of said composition, a diluted detergent solution comprising the above composition is also part of the invention.

    used commercially available celluloses. For example Celluzyme, Carezyme®, Medley®, Sumizyme, Endolase, Celluclean® from Novozymes.
    On the other hand, pectate liases are capable of breaking down or separating pectino groups, substrates of polysaccharides found in the cell wall of plants. Enzymatic activity is provided by pectate liases that hydrolyze (1,4) -alpha-D-galacturonan to give oligosaccharides.
    To obtain the detergent composition described herein, commercially available pectate liases can be used. For example Pectinex®, Pectinex® Ultra, Xpect from Novozymes.
    The detergent composition of the present invention comprises between 0.25% and 2.5% of the specific enzyme combination, amounts expressed in percentage by weight of enzymes with respect to the total weight of the composition, although for the preparation of this composition Diluted solutions of one or more of the enzymes in the combination can be used.
    In preferred embodiments, the combination of enzymes of the composition described herein comprises:
     - between 40% and 55% protease, preferably between 40% and 50%;
     - between 5% and 15% lipase, preferably between 5% and 10%;
     - between 35% and 50% amylase, preferably between 30 and 40%; Y
    - between 1 and 14% of an enzyme selected from cellulase and pectin lyase, preferably between 2% and 12%; where all amounts are expressed as a percentage by weight of each enzyme with respect to the total weight of the enzyme combination, and
     where the sum of these enzymes is less than or equal to 100% of the total weight of the enzyme combination.
    When the sum of the enzymes specified in the preceding paragraph is less than 100% of the total weight of the enzyme combination, it may comprise other optional enzymes. However, it is preferred that the sum of the enzymes specified in the preceding paragraph be equal to 100% of the total weight of the enzyme combination, in which case, the enzyme combination consists of:

    soluble complexes with metal ions, especially calcium and magnesium ions. This allows to improve the detergent properties of the surfactants and prevents the precipitation of insoluble metal salts, especially calcium and magnesium. A preferred range in the composition is between 0.5% and 2% by weight with respect to the total weight of the detergent composition.
    Some of the sequestering agents that can be used in the composition described in this application may be aminopolycarboxylates such as EDTA (ethylenediaminetetraacetic acid), MGDA (diacetic methylglycine acid), GLDA (n, n-dicarboxymethyl glutamic acid), iminodisuccinic acid, DTPA (diethylenetriamine pentacetic acid), its sodium salts or any mixture of the foregoing; phosphonates such as AEPN (2-aminoethylphosphonic acid), HEDP (1-hydroxyethylidene-1,1-diphosphonic acid), ATMP (aminotris (methylene phosphonic acid)), EDTMP (ethylenediamine tetra (methylene phosphonic acid), DTPMP (diethylenetriaminopenta (methylene) phosphonic acid) , PBTC (phosphobutane-tricarboxylic acid), TDTMP (tetramethylenediaminetetra (methylene phosphonic acid)), HDTMP (hexamethylenediaminetetra acid (methylene phosphonic)) or a mixture of the foregoing.
    In preferred embodiments of the present invention, the sequestering agent is selected from the group consisting of the sodium salts of EDTA, MGDA, GLDA, sodium iminodisuccinate and any combination of the foregoing.
    Additionally, the detergent described in this application comprises at least one pH regulating agent. This compound may be acidic, preferably selected from the group consisting of citric acid, phosphoric acid, acetic acid, lactic acid, malic acid, formic acid and tartaric acid. Alternatively, the pH regulating agent may be alkaline or basic in character, preferably selected from the group consisting of sodium hydroxide, potassium hydroxide and alkanolamines. A preferred range in the present composition is between 2% and 10% by weight with respect to the total weight of the detergent composition.
    Preferably, all the detergents described can be prepared diluted in water at a concentration or dose between 1% and 5% by weight with respect to the total weight of the diluted solution, preferably between 1% and 3% by weight with respect to the total weight of the diluted solution.

    preferably by circulation of the diluted solution through the closed circuit or surface to be treated.
    The diluted solution will preferably be at a temperature between 15 ° C and 60 ° C, being even more preferable between 40 ° C and 50 ° C.
    The contact time will depend on the type of biofilm and its thickness, with 30 to 90 minutes being preferable for CIP systems, that is, closed systems, when the temperature is between 40 and 50 ° C. On the other hand, for open surfaces the time will be
    10 preferably 15 and 30 minutes.
    The rinsing of step b) is performed with water. In the case of open surfaces it is preferred to use pressurized water, while in closed surfaces and circuits water circulation is preferred.
    In other preferred embodiments of the present invention, the method of controlling and / or removing biofilm from a surface comprises an additional step c) of applying a disinfectant. Among the selected disinfectants are preferably oxidizing disinfectants such as, for example, peracetic acid, hydrogen peroxide or
    20 sodium hypochlorite.
    The method of control and / or elimination of biofilm can be applied to all types of surfaces and materials on which a biofilm has been developed, in particular stainless steel, soft metals such as aluminum, brass, bronze, galvanized, ceramic materials or
    25 plastic materials. Preferably the surfaces to be treated will be within the usual in the food, pharmaceutical, cosmetic and chemical industries.
