Description of the invention

The subject of the invention is an agent for cleaning machines and engines used in workshops, industry and households.

Water-free systems, such as organic solvents, kerosene and the like, or water-based systems containing surfactants are most often used for washing engine, machine or vehicle components.

According to the application WO 00/71655, the vehicle cleaner comprises block copolymers of ethylene oxide and propylene and anionic surfactants such as salts of sulfated fatty ether alcohols or sulfonated alkylbenzenes.

EP0137615 and EP0137616 disclose contaminant removal oil-water microemulsion systems containing at least 5% non-polar solvents, for example terpene.

US Patent No. 6,573,230 in the composition of the washing liquid, in addition to the anionic surfactant (sulphonic derivatives), non-ionic surfactant (ethoxylated polyhydroalcohols derivatives), ethylene oxide / propylene oxide copolymers, short-chain hydrophilic-lipophilic compound, magnesium salt (e.g. fatty acid, sulphate), of a biocide (e.g. bromo or isothiazoline derivatives) contains biodegradable chelating agents in the form of succinic or acetic acid derivatives (e.g. ethylenediamine N, N-disulfosuccinate or methyl glycine N, N-diacetate salt).

In US Patent No. 3,935,130, the washing liquid contains, in addition to the anionic (sulfonic) and non-ionic surfactants, small amounts of glycol ether solvent and an organic amine.

There are also known applications of fatty acid methyl esters, mainly from rapeseed oil, for lubricants and cleaning agents used in the engineering and defense industry. In a collective work edited by W. Podkówka "Biofuel, glycerine, rapeseed feed" there are listed patented applications of fatty acid methyl esters from rapeseed oil in agents for cleaning and preserving weapons, as solvents and as carriers for pigments or dyes.

Kerosene with properties compliant with the PN-71 / C-96043 standard or its mixtures with oils, liquid paraffins or fatty acid methyl esters is most often used for cleaning internal combustion machinery and engines. The disadvantage of these agents is that they leave a greasy film on the cleaned surfaces.

Japanese patent specification JP 2000051600 describes the process of washing machine and vehicle parts. The first stage is washing with kerosene alone, the second is drying in hot air.

Japanese patent JP 6146034 describes a two-stage washing process for machine parts. The first stage of the process is kerosene washing in a circulation system and kerosene recovery. The second stage is washing with water with the addition of a corrosion inhibitor at 45 ° C.

Surprisingly, it turned out that the washing agent in the form of an aqueous solution, containing ethoxylated fatty acid methyl esters, obtained by direct ethoxylation of fatty acid methyl esters, possibly with the addition of liquid hydrocarbons, such as kerosene and non-ionic or anionic emulsifiers, such as such as fatty alcohol ethoxylates or their sulphated derivatives, fatty amine oxides.

Such agent can be perfectly rinsed off with water from the cleaned surfaces. In addition, by controlling the concentration of oxyethylates, kerosene and water, the consistency of the composition can be varied from a liquid emulsion to a solid gel.

The advantage of the gel is that it adheres to the surface, giving the agent a longer contact time with the dirt; and by not flowing, it saves the preparation and reduces the discharge of sewage.

The agent according to the invention contains an aqueous solution of fatty acid methyl ester oxyethylates obtained by direct ethoxylation of fatty acid methyl esters from rapeseed oil with a chain length of C16-C20 and at a concentration of 15-55 cg / g.

Preferably, the composition comprises rapeseed oil fatty acid methyl ester oxyethylates with an average degree of 5-10 oxyethylation.

Preferably, the composition comprises kerosene or other hydrocarbons in an amount of 0-20 cg / g.

PL 206 552 B1

The invention relates to the use of fatty acid methyl esters, in particular those derived from rapeseed oil, in aqueous or oil-water systems as an environmentally renewable surfactant base. The fatty acid methyl ester oxyethylates used are obtained by direct reaction of ethylene oxide with the starting fatty acid methyl esters. It is preferred that the average degree of ethoxylation is 5-10. The ethoxylation products obtained in this way contain the appropriate composition of ingredients necessary for the formation of emulsions in aqueous systems. As the oil fraction, liquid hydrocarbons, for example kerosene, can be used. As emulsifiers in an amount of 0-4%, ethoxylated fatty or synthetic alcohols, their sulphated derivatives, or fatty amine oxides can be used.

The agent according to the invention easily spreads in water in the form of an emulsion and does not remain on the cleaned surfaces after rinsing.
