The present invention relates to a cleaning and degreasing agent which solves the removal of mineral and organic impurities and microorganisms and their products from dairy equipment and containers used mainly in the food industry.

The prior art cleaning and de-oiling agents used for cleaning of pharmaceutical equipment and containers are either generally used for other conventional cleaning operations and have low efficiency 'for this area' of application or products having a high pH (above 10). Strong alkaline agents have an adverse effect on the removal of proteinaceous contaminants, and there is a risk of damage to the surface of some materials of the equipment and containers to be cleaned. The disadvantage of some formulations is the high foaming power of the application. low disinfectant effects.

The above drawbacks are eliminated by a cleaning and degreasing agent for dairy equipment and / or containers according to the invention, based on flax and nonionic surfactants with an adjuvant additive consisting of

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

0.3 to 12 wt. ethoxylated and / or propoxylated organo-compounds containing at least one -OH group having 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. % of chloroform, preferably in the form of complex compounds, with an active chlorine content of from 0.01 to 7 g per 100 g of the substance, up to 25 wt. an alkaline organic compound having 1 to 8 carbon atoms, up to 30% by weight. organoocohols and / or inorganic substances forming complexes with water ions with water-soluble compounds and the remainder being excipients such as solvents, meohanic agents and / or mineral alkalis ·

The essence of the present invention is a detergent composition comprising a combination of ionic and nonionic surfactants and adjuvants to achieve effective removal of mineral, fatty, protein and sugar impurities and microorganisms.

Adjuvants refer to products which functionally enhance the activity of superficially active substances, reduce the negative effect of substances contained in water and / or stabilize in the prepared system. It is effective to use substances with effect in multi-directional directions, such as the use of disodium carbonate, which modifies the hardness of the water and thereby increases the exposure of the superactive substances; sodium chloride, which affects the critical mineral concentration values. Other types of excipients are e.g. lower aliphatic alcohols, which improve the solubility of system components and favor wetting, while allowing the distribution of products also in winter. The types of these substances and their functional function are known or derivable from the art.

The adverse effect of microorganisms ea is eliminated in the cleaning composition according to the invention by substances having both active and bound chlorine, which are termed, in terms of active chlorine, as chloroforms. Such a substance is e.g. chlorine lime, alkaline halogens, as well as organic substances which are labile bound in the molecule.

The term complexing agents a and include inorganic or organic substances forming complex ions which are water-soluble by metal ions. These are, in particular, iron-forming substances, of which ethylenediaminotetraootic acid or its inorganic salts are exemplified.

The synergistic balanced composition of the aa composition will achieve optimal detergent and disinfectant effects, thereby reducing the demands on the cleaning process, the amount of the composition, the water consumption and the reading temperature. The low foaming of the composition improves the proemia and reduces the foam-induced complications during the cleansing operation. The chemical composition of the mesoactive substances in the composition is such that ioh biodegradability is high.

Example 1 wt. parts by weight of dodeoylhenzenesulfonic acid with a concentration of 85% by weight. is mixed with 5 wt. parts of triethanolamine. 5 wt. parts by weight of ethylenediaminetetraootic acid sodium, 2.8 wt. parts of an alkylpolyethylene glycol ether having 12 to 16 carbon atoms in the alkyl and 10 to 15 moles of bound ethylene oxide per molecule,

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

The composition is clear, yellowish and slightly viscous and used for purification at 5 to 50 g / l at 20 to 35 ° C.

Example 2

10.0 wt. parts of alkylpolyethylene glycol ether having 12 to 16 carbon atoms and 10 to 15 moles of bound ethylene oxide are mixed with 2.0 wt. parts by weight of nonylphenylpolyethylene glycol ether with 10 moles of bound ethylene oxide per molecule, 2.5 wt. parts of the chloroform complex prepared by reacting the mixture in a 1: 1 weight ratio of dodeoylphenyl polyglycol ether and a copolymer of propylene oxide with ethylene oxide having an average molecular weight of 1,500 with a halide, the active content of the product being 5.5 g / 100 g of product and 2.0 wt. deddoylbenzenesulfonic acid sodium salt. After dissolution, a 20% aqueous solution of 14.0 wt. parts (calculated on oil solids) of ethylene -198,481 diamintetraootic acid sodium salt and 12 parts by weight of triethanolamine. With stirring, ca 2.0 wt. % n-butanol and 10 wt. parts of tripropylene glycol. The composition is a slightly viscous, slightly yellow-brown color and a hole. When cleaning dairy containers at 18-25 ° C and at a dilution of 5-40 g / l water, it will prove to be very effective both in the centrifugation of mineral and organic impurities and to eliminate the microorganisms present.

Example 3

The system is prepared from the same starting materials as in Example 2, except that a 6 wt.% Mixture is used instead of triethanolamine. parts by weight of triethanolamine and 10 wt. parts of urea. 5% by weight of n-butanol are added as adjuvants to modify the physical properties of the system. parts of polyethylene glycol having a molecular weight of 300. The prepared dispersion composition is used under the same conditions as in Example 2.

The effect was controlled from the point of removal of microorganisms by sterile walls from various sites of the cleaned containers and the alignment, the sterile being applied to a sterile nutrient fall and at a standard time and constant. Under the conditions (including the wash concentration of the active ingredient), colony growth was monitored.

The rating was as follows:

++ increase consistent with reference sample from contaminated container (cleaning ineffective) + reduced increase relative to observation sample (low efficiency cleaning) without increase (cleaning efficient)

This methodology achieved the following results:
