Definitions
- the present invention relates to enzyme-containing detergents and cleaning agents which, in addition to the usual constituents, contain an amylase from Bacillus amyloliquefaciens and a specific surfactant system.
- detergents In addition to the ingredients that are indispensable for the washing process, such as surfactants and builder materials, detergents generally contain other ingredients, which can be summarized under the term washing aids and which include such different active ingredient groups as foam regulators, graying inhibitors, bleaching agents, bleach activators and color transfer inhibitors. Such auxiliaries also include substances which support the surfactant performance through the enzymatic degradation of soiling on the textile. The same applies analogously to cleaning agents for hard surfaces. In addition to the proteases that support protein removal and the fat-cleaving lipases, amylases are of particular importance.
- Amylases have the task of facilitating the removal of starchy soiling by the catalytic hydrolysis of the starch polysaccharide and for this purpose have been used for a long time in detergents for dishes, but also in detergents for use in textile washing. For the most part, it was previously a thermostable amylase from Bacillus licheniformis, which is commercially available, for example, under the name Termamyl®. More recently, such agents have increasingly used genetically modified amylases, that is to say with amino acid sequences modified in comparison to naturally occurring amylases with the aid of genetic engineering methods. In addition to increasing their performance, the genetic modification of amylases essentially aims to increase the stability of the enzyme, in particular against the attack of oxidizing agents.
- the invention therefore relates to an amylase-containing washing or cleaning agent which contains ⁇ -amylase from Bacillus amyloliquefaciens and a system of anionic and nonionic surfactant in which the amount of the nonionic surfactant predominates, in addition to the usual ingredients compatible with such constituents.
- Another object of the invention is the use of a corresponding combination to increase the cleaning performance of detergents and cleaning agents, especially in relation to starchy soiling, when used in, in particular, aqueous washing and cleaning solutions.
- ⁇ -Amylase from Bacillus amyloliquefaciens has long been known, for example from US Pat. No. 1,227,374. For example, it is commercially available under the name Amylase BAN®.
- An agent according to the invention preferably contains 0.001 mg to 0.5 mg, in particular 0.02 mg to 0.3 mg, of amylolytic protein per gram of the total agent.
- the protein concentration can be determined using known methods, for example the Bicinchonic acid method (BCA method, Pierce Chemical Co., Rockford, IL) or the Biuret method (AG Gornall, CS Bardawill and MM David, J. Biol. Chem. 177, 751-766, 1948).
- the detergents and cleaning agents according to the invention which can be present in particular as powdery solids, in post-compacted particle form, as homogeneous solutions or suspensions, can, in addition to the active ingredient combination used according to the invention, in principle contain all known ingredients which are customary in such agents.
- the agents according to the invention can include, in particular, builder substances, bleaching agents based on organic and / or inorganic peroxygen compounds, bleach activators, water-miscible organic solvents, additional enzymes, sequestering agents, electrolytes, pH regulators and other auxiliaries, such as optical brighteners, graying inhibitors, color transfer inhibitors, foam regulators , Silver corrosion inhibitors and dyes and fragrances.
- the agents according to the invention contain one or more surfactants, and in addition to nonionic surfactants and anionic surfactants, their mixtures with cationic, zwitterionic and / or amphoteric surfactants are also suitable.
- the proportion of nonionic surfactant in the system of anionic surfactant and nonionic surfactant is preferably more than 75% by weight, in particular 80% by weight to 99% by weight, although the case may also arise that the surfactant system consists entirely of non-ionic surfactant.
- Suitable nonionic surfactants are in particular alkyl glycosides and ethoxylation and / or propoxylation products of alkyl glycosides or linear or branched alcohols each having 12 to 18 carbon atoms in the alkyl part and 3 to 20, preferably 4 to 10, alkyl ether groups.
- alkyl glycosides and ethoxylation and / or propoxylation products of N-alkyl amines, vicinal diols, fatty acid esters and fatty acid amides which correspond to the long-chain alcohol derivatives mentioned with regard to the alkyl part, and also of alkyl phenols with 5 to 12 carbon atoms in the alkyl radical, can be used.
- the nonionic surfactants used are preferably alkoxylated, advantageously ethoxylated, in particular primary alcohols having preferably 8 to 18 carbon atoms and On average, 1 to 12 moles of ethylene oxide (EO) are used per mole of alcohol, in which the alcohol radical can be methyl-branched linearly or preferably in the 2-position or can contain linear and methyl-branched radicals in the mixture, as is usually present in oxo alcohol radicals.
- EO ethylene oxide
- alcohol ethoxylates with linear residues of alcohols of native origin with 12 to 18 carbon atoms, for example from coconut, palm, tallow or oleyl alcohol, and an average of 2 to 8 EO per mole of alcohol are particularly preferred.
- Preferred ethoxylated alcohols include, for example, C 12 -C ⁇ 4 - alcohols with 3 EO or 4 EO, C 1 -C1 9 alcohols containing 7 EO, C 13 - C 15 alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C 12 -C ] 8 - alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of -C 4 -C alcohol with 3 EO and C 12 - C 18 alcohol with 7 EO.
- the degrees of ethoxylation given represent statistical averages, which can be an integer or a fraction for a specific product.
- Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE).
