Abstract

The invention relates to enzyme preparations in granular form, which contain a carrier-bound antioxidant, as well as new, carrier-bound antioxidants and liquid washing-active preparations which simultaneously contain a solid enzyme granules and a bleaching agent.

Description

object The invention are enzyme preparations in granular form, which are a carrier-bound Contain antioxidants, as well as new, carrier-bound Antioxidants and liquid detergent compositions, which at the same time contain a solid enzyme granulate and a bleaching agent.

enzyme preparations have gained importance in many fields of technology. So they are used in detergents and cleaners to improve the Performance especially against enzymatic degradable soils such as proteins, starch and the like used. However, enzymes are known to be complex Proteins easily lose their performance due to chemical influences. This is especially true when bleaches are present.

In the international application WO 00/27978 A1 discloses liquid detergents and cleaners which contain antioxidants as radical scavengers to protect against oxidation reactions which are triggered by free radicals. Suitable radical scavengers, for example, polyhydroxybenzoic acids are listed in this document. Such antioxidants protect the enzyme. The disadvantage, however, is that they often have a negative influence on the bleach system. This applies in particular to modern bleaching agents such as phthalimidohexane percarboxylic acid (PAP).

From the European patent application EP 0290223 are known preparations of hydrolytic enzymes and bleaching agents containing such preparations. There are proposed there particulate enzyme products containing a core in which the hydrolytic enzyme is located and a coating layer comprising this core, wherein the coating layer contains a substance which reacts with oxidizing agents, deactivate the enzymes. The enzyme protection agent is selected from the group of alkali salts, mixtures of alkali salts with a pH> 10, the reducing agent, the antioxidant and the transition metal complexes.

In front Background of this prior art, the inventors have tasked to provide antioxidants that as constituents of enzyme granules even then not for degradation of bleaches, if these at the same time as a disperse phase are present in the same product matrix.

The Solution of this problem is achieved by enzyme preparations in granular form, containing one or more enzymatically active Proteins and, if desired, adsorbents, granulating aids and / or coating agent, characterized in that above an effective amount of a carrier-bound antioxidant is included.

In a general embodiment, the invention relates thus carrier-bound antioxidants. For the purposes of the invention are preferably carrier-bound Antioxidant based on low molecular weight antioxidants those via free hydroxyl groups or carboxylic acid groups with which they are esterified by organic Carrier or by salt formation on inorganic carriers ge can be tied. Under free hydroxyl groups respectively Carboxylic acid groups are understood here to mean such groups with an organic acid or a Alcohol can be converted to an ester without causing the antioxidant Properties of the reaction product are lost. Suitable antioxidants are naturally occurring antioxidants, for example, those used in the food industry especially antioxidants such as tocopherol, its derivatives, ascorbic acid and the same. Another important class is phenolic antioxidants. These are hydroxyphenyl compounds with at least one other Substituents, in particular an OH group or carboxyl group, preference is given to compounds which form quinoidal structures can. Among these compounds are di- and trihydroxybenzoic acids preferred, especially gallic acid.

According to the invention the antioxidants bound to carriers. To this Connection is a variety of chemical reactions suitable, the preferably to covalent bonds between the antioxidant and lead the carrier. Particularly preferred it, corresponding antioxidants by ester bonding to a Tie wearers.

A According to the invention preferred class carrier-bound Antioxidants are esters of acid group-containing Antioxidants such as the aforementioned hydroxybenzoic acids or ascorbic acid and polymers having hydroxyl groups.

As polymers with hydroxyl groups can thereby polymers, that is by radical polyme polymers, polycondensates, that is to say those produced by esterification, amide formation and the like, addition polymers, that is to say polymers which can be prepared by reacting diisocyanates and diols and similar reactions, or else naturally occurring polymers, such as, for example, polysaccharides, lignin and the like can be used. The said polymers are reacted under conventional esterification conditions with the antioxidants.

To Another embodiment of the invention will be Antioxidants in acid form to basic surfaces inorganic substances capable of salt formation, added. So you can, for example, ascorbic acid or hydroxybenzoic acids, in particular gallic acid, on finely divided solid inorganic oxides salt-like or covalently bound. Suitable oxides are oxides and or oxide hydrates, and or hydroxides of aluminum, zinc, Titans and or the silicon.

To In a particularly preferred embodiment, the aforementioned acid group-containing antioxidant esterified with polymers having hydroxyl groups. So can For example, homopolymers or copolymers of hydroxyethyl acrylate or hydroxyethyl methacylate with the corresponding acids implement. After a likewise particularly preferred procedure starting from polyvinyl acetate, the at least partially to Polyvinyl alcohol is saponified then followed by the Polyvinyl alcohol with the acid group of the antioxidant is esterified.

To a further preferred embodiment of the invention become the acids of the antioxidants with polyesters, Polyamides or polyurethanes which carry hydroxyl end groups, esterified. Corresponding polyesters, polyamides or polyurethanes can be linearly branched or hyperbranched. Highly branched products are due to their higher number of binding sites, based on the molecular weight, preferred.

To a further preferred embodiment of the invention become the antioxidants via hydroxyl groups bound polymeric acids. Suitable polymeric acids are, for example, homo- and copolymers of acrylic acid, methacrylic acid, itaconic acid or maleic acid. In the latter case, particular preference is given to copolymers which Contain maleic anhydride structures, which then become with the OH groups of, for example, ascorbic acid or let the gallic acid ring open.

To a further preferred embodiment of the invention The low molecular weight antioxidants are controlled by their acid groups hydroxyl-containing polymers of natural origin such as starch, cellulose, guar or their synthetic etherification products bound. In particular, such natural hydroxyl-containing polymers to the inventive Antioxidant compounds are reacted, usually as a carrier for enzyme in enzyme granules be used, such as starch, cornmeal and the same.
