The invention relates to a cleaning and degreasing agent that addresses the removal of mineral and organic impurities and microorganisms and their products from dairy equipment and containers used primarily in the food industry.

Previously known cleaning and degreasing agents used for cleaning medical equipment and containers are either agents generally used for other common cleaning operations and have low efficiency for this area of application or agents that have a high pH value (above 10). Strong alkaline agents have an adverse effect on the removal of protein components of impurities, and there is a risk of damaging the surfaces of some materials of the cleaned equipment and containers. The disadvantage of some agents is strong foaming during application, possibly low disinfection effects.

The above-mentioned shortcomings are eliminated by a cleaning and degreasing agent for dairy equipment and/or containers according to the invention, based on ionic and nonionic surfactants with the addition of auxiliary substances, which consists of

0.5 to 10 wt. of an ionic sulfonic organic compound, preferably an alkylbenzenesulfonic acid with 9 to 12 carbon atoms in the alkyl,

0.3 to 12 / wt. of ethoxylated and/or propoxylated organic compounds containing at least one -OH group with 4 to 22 carbon atoms, to which 2 to 15 moles of ethylene oxide and/or propylene oxide are attached,

5.1Ο ³ to 5 5» wt. chloroformic substance, preferably in the form of complex compounds, with an active chlorine content of 0.01 to 7 g per 100 g of substance, up to 25 wt. % alkali-treated organic substance with 1 to 8 C atoms, up to 30 wt. % organic and/or inorganic substances forming complex compounds with metal ions that are soluble in water and the remainder are auxiliary substances, such as solvents, mechanically acting substances and/or mineral alkalis.

The essence is the composition of the cleaning agent, which is made up of a combination of ionic and non-ionic surfactants and auxiliary substances, which achieve effective removal of mineral, fatty, protein and sugar impurities and microorganisms.

The term auxiliaries refers to products that functionally enhance the action of surfactants, reduce the negative effect of substances contained in water and/or act as stabilizers in the prepared system. It is effective to use substances with an effect in several directions, such as, for example, the use of disodium carbonate, which adjusts the hardness of water and thereby increases the action of surfactants, and, for example, sodium chloride, which affects the values of the critical mineral concentration. Other types of auxiliaries are, for example, lower aliphatic alcohols, which improve the solubility of the system components and have a positive effect on wetting, while also enabling the distribution of products even in winter. The types of these substances and their functional effect are known or deducible from the professional literature.

The adverse effect of microorganisms is eliminated in the cleaning agent according to the invention by substances that have both active and bound chlorine and which, in relation to active chlorine, are referred to as chlorophore substances. Such a substance is, for example, chlorinated lime, alkaline chlorates, as well as organic substances containing labilely bound chlorine in the molecule.

The term complexing agents includes inorganic or organic substances that form complex compounds with metal ions that are soluble in water. These are mainly chelating agents, of which ethylenediaminetetraacetic acid or its inorganic salts are given as an example.

The synergistic balanced composition of the agent achieves optimal detergent and disinfectant effects, thereby reducing the demands on the cleaning process in terms of cleaning operation time, amount of agent, water consumption and cleaning temperature. The low foaming of the agent improves the cleaning process and reduces complications caused by foaming during the cleaning operation. The chemical composition of the surfactants in the agent is such that their biodegradability is high.

Example 1 parts by weight of dodeoylbenzenesulfonic acid with a concentration of 85% by weight is mixed with 5 parts by weight of triethanolamine. To the resulting mixture are added 5 parts by weight of sodium salt of ethylenediaminetetraacetic acid, 2.8 parts by weight of alkyl polyethylene glycol ether with 12 to 16 C atoms in the alkyl and 10 to 15 moles of bound ethylene oxide per molecule,

2.0 wt. parts of ethylene oxide tall oil with 5 moles of bound ethylene oxide and 2.3 wt. parts of a chlorophore complex prepared by reacting nonylphenyl polyglycol ether with 9 moles of bound ethylene oxide with chlorine with an active chlorine content of 0.2 g/100 g of product, in the form of a 10% aqueous solution. Finally, 10 wt. parts of ethanol and 5 wt. parts of polyethylene glycol with an average molecular weight of 600 are added to the resulting system.

The prepared product is clear, yellowish and slightly viscous and is used for cleaning in a dilution of 5 to 50 g/l at a temperature of 20 to 35 °C.

Example 2

10.0 parts by weight of alkyl polyethylene glycol ether with 12 to 16 C atoms in the alkyl and 10 to 15 moles of bound ethylene oxide are mixed with 2.0 parts by weight of nonylphenyl polyethylene glycol ether with 10 moles of bound ethylene oxide per molecule, 2.5 parts by weight of a chlorophore complex prepared by reacting a mixture in a weight ratio of 1 to 1 of dodeoylphenyl polyglycol ether and a copolymer of propylene oxide with ethylene oxide with an average molecular weight of 1,500 with chlorine, the active chlorine content in the product being 5.5 g/100 g of product and 2.0 parts by weight of sodium salt of dedetoylbenzenesulfonic acid. After dissolution, a 20% aqueous solution with 14.0 wt. parts (calculated on the oil dry matter) of sodium salt of ethylene198 481 diaminetetraacetic acid and 12 parts by weight of triethanolamine. While mixing, add 2.0 parts by weight of n-butanol and 10 parts by weight of tripropylene glycol. The prepared composition is slightly viscous, slightly yellow-brown in color and has holes. When cleaning dairy containers at a temperature of 18 to 25 °C and in a dilution of 5 to 40 g/l of water, it proves to be very effective in removing both mineral and organic impurities and also eliminates the microorganisms present.

Example 3

A system is prepared from the same starting materials as in Example 2, with the only difference that instead of triethanolamine a mixture of 6 parts by weight of triethanolamine and 10 parts by weight of urea is used. As an auxiliary substance to adjust the physical properties of the system, instead of n-butanol 5 parts by weight of polyethylene glycol with a molecular weight of 300 is added. The prepared distiller is used under the same conditions as in Example 2.

The effect was checked in terms of the removal of microorganisms by swabs from the walls of various places of the cleaned containers and equipment, whereby the swab was placed on a sterile nutrient medium and the growth of the colony was monitored for a standard time and constant conditions (including the concentration of the active substance during washing).

The rating was as follows:

++ increase identical to the comparison sample from the dirty container (cleaning ineffective) + reduced increase compared to the observation sample (cleaning not very effective) no increase (cleaning effective)

This methodology achieved the following results:

Type of substance Samples No. Overall rating cleaning 1 2 3 4 5 Sodium bicarbonate + ++ + ++ ineffective Nonionic surfactant + + + + very little effective Chloroform substance + 0 + 0 + not very effective substance according to example 1 0 0 0 +. 0 effective substance according to example 2 0 0 0 0 0 effective substance under example 3 0 0 0 0 0 effective
