Definitions
- the invention is in the field of cleaning agents and relates to novel preparations especially for the (spray) cleaning of sheet metal, body parts and vehicles containing special ester quats and the use of these cationic surfactants for cleaning hard surfaces.
- Cationic surfactants are particularly important here because they are not only high Have cleaning power - especially in combination with non-ionic surfactants - but also make bodies and vehicles hydrophobic and thus protect them. At the same time, they work antistatic, i.e. Static charging is also used when spray cleaning under high pressure counteracted the metal parts. So far, tetraalkylammonium salts have been used in practice of the dimethyldistearylammonium chloride (DMDSAC) type as particularly effective proved, while cationic surfactants of the conventional ester quatt type which the DMDSAC otherwise ousted in many applications, have so far been ineffective.
- DMDSAC dimethyldistearylammonium chloride
- the object of the present invention was to create new preparations for cleaning hard surfaces, especially for spray cleaning metal sheets and High-pressure cleaning of vehicles to provide the cationic surfactants included, but are characterized by better biodegradability and thereby at the same time at least the level with regard to hydrophobization and antistatic finish state of the art.
- the invention relates to new cationic preparations for cleaning hard surfaces, which are characterized in that they contain esterquats as cationic surfactants, the Acyl radical or acyl radicals are unsaturated fatty acids with 8 to 22 and preferably Derive 16 to 22 carbon atoms and iodine numbers above 50. Another advantage The new esterquats are that they are still in very high concentrations transparent and fluid and therefore easy to use.
- esters generally means quaternized fatty acid triethanolamine ester salts. These are known substances that can be obtained using the relevant methods of preparative organic chemistry.
- German patent DE 4308794 C1 also discloses a process for the preparation of solid ester quats , in which the quaternization of triethanolamine esters is carried out in the presence of suitable dispersants, preferably fatty alcohols.

- an application ratio of 1.2: 1 to 2.2: 1, preferably 1.5: 1 to 1.9: 1 has proven to be particularly advantageous.
- the preferred esterquats are technical mixtures of mono-, di- and triesters with an average degree of esterification of 1.5 to 1.9.

- Both fatty acids and the corresponding triglycerides can be used to prepare the esterquats of the formulas (I) to (IV).
- Such a method which should be mentioned as representative of the corresponding prior art, is proposed in the European patent EP 0750606 B1 (Cognis). It is also possible to carry out the condensation of the alkanolamines with the fatty acids in the presence of defined amounts of dicarboxylic acids, such as, for example, oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid, glutaric acid, adipic acid, sorbic acid, pimelic acid, azelaic acid, sebacic acid and / or dodecanedioic acid.

- esterquats are usually commercially available in the form of 80 to 90% strength by weight alcoholic solutions, which can be diluted with water if required.
- the finished preparations usually contain the esterquats - based on the composition - in amounts of 1 to 10 and preferably 2 to 8% by weight.
- these can also contain other conventional auxiliaries and additives, but especially cosurfactants, where it is the latter because of their particular compatibility with the nonionic cationic surfactants Connections.
- nonionic surfactants are fatty alcohol polyglycol ethers, alkylphenol polyglycol ethers, Fatty acid polyglycol ester, fatty acid amide polyglycol ether, fatty amine polyglycol ether, alkoxylated triglycerides, mixed ethers or mixed formals, alk (en) yl oligoglycosides, fatty acid N-alkyl glucamides, Protein hydrolysates (especially vegetable products based on wheat), Polyol fatty acid esters, sugar esters, sorbitan esters, polysorbates and amine oxides.
- nonionic surfactants contain polyglycol ether chains, these can be a conventional, but preferably have a narrow homolog distribution. Preferably become fatty alcohol polyglycol ethers, alkoxylated fatty acid lower alkyl esters or alkyl oligoglucosides used.
- the preferred fatty alcohol polyglycol ethers follow the formula (V) R 8 O (CH 2 CHR 9 O) n1 H (V) in which R 8 represents a linear or branched alkyl and / or alkenyl radical having 6 to 22, preferably 12 to 18 carbon atoms, R 9 represents hydrogen or methyl and n1 represents numbers from 1 to 20.
