Definitions
- the invention encompasses an enzyme containing preparation containing a protease and at least one other enzyme and a detergent containing such preparation.
- preparation means either a granulate or a liquid slurry.
- the slurry can be either anhydrous or substantially anhydrous, or it can be aqueous.
- enzyme containing preparations can be used in different fields, e.g. in the field comprising digestive aids and in the detergent field, but their main use is to be found in the detergent field.
- Enzyme containing granulates are widely used in industry, mainly as dust free additives to detergents.
- protease containing granulates One of the big problems in regard to protease containing granulates is the storage stability of other enzymes present in the granulate. Another big problem in regard to enzyme containing granulates is the storage stability of the enzymes when the enzyme containing granulate is mixed with the other detergent components. Even if several methods for stabilization of the enzymatic activity have been devised, the stability of the enzymatic activity in the enzyme granulate containing detergents is still open to improvement. Another problem in regard to enzyme containing granulates is the color, as most enzyme containing granulates will be discolored, if not coated with e.g. TiO2. A third problem in regard to enzyme containing granulates is the smell thereof. Even after a fairly good purification of the enzyme containing fermentation broth the finished product often exhibits an unagreeable strong smell.
- Anhydrous or substantially anhydrous slurries are widely used in industry, mainly as additives to liquid detergents.
- Aqueous slurries can be used as additives to liquid detergents, in the starch industry and in the food industry. If the slurry is aqueous the water activity or the ionic strenght in the slurry has to be controlled in such manner that the entire amount or substantially the entire amount of the crystalline enzyme is maintained in the crystalline form.
- a big problem in relation to liquid detergents is the stability of enzymes added to these.
- Several stabilization systems have been used in an attempt to overcome this problem. Within the field of low pH formulations both calcium, formate and borate stabilization has been used and are used. Within the higher pH range some of the inhibition methods are also used. But especially within structured liquids a hydrophobic encapsulation has been used, vide Gb 2,186,884A. However, all these stabilization systems are open to improvement.
- Another big problem in regard to liquid, enzyme containing preparations is the color. Most liquid, enzyme containing preparations are colored due to impurities, usually with a dull, brownish color, and also, the color varies somewhat from batch to batch.
- the purpose of the invention is the provision of an enzyme containing preparation, which exhibits an improved stability, and which is colorless or almost colorless and of a high purity, and thus without any smell problems, and a detergent containing such enzyme containing preparation.
- the enzyme containing preparation according to the invention is characterized by the fact that it contains a protease and at least one protease sensitive enzyme, wherein substantially 100% of the proteolytic activity and/or substantially 100% of the protease sensitive enzyme or the protease sensitive enzymes are present as crystals, wherein more than 90% of the crystals possess a maximum crystal dimension between 0.01 ⁇ m and 500 ⁇ m, preferably between 0.1 ⁇ m and 100 ⁇ m, and that the preparation preferably contains a stabilizing agent for the enzymes.
- the stability problems in regard to the protease sensitive enzyme(s) are usually minor.
- the microorganism from which the protease is produced usually differs from the microorganism(s), from which the protease sensitive enzyme(s) is (are) produced, and in such cases serious stability problems may occur.
- the enzyme containing preparation according to the invention it surprisingly has been found that these stability problems are largely eliminated.
- the enzyme containing preparation according to the invention when present in a detergent, possesses an equally good or better enzyme stability than otherwise similar but less pure enzyme containing preparations.
- the protease is Savinase® and the preparation contains the lipase Lipolase® as the other enzyme, and if the preparation is a slurry it has been found that the lipase exhibits an excellent stability.
- the protease sensitive enzyme or the protease sensitive enzymes are present as crystals only a small amount of the protease sensitive enzyme(s) or nothing thereof will be dissolved in the preparation according to the invention, and thus, the stability of the protease sensitive enzyme(s) in the preparation according to the invention will be improved. If the protease is Savinase® and the preparation contains the lipase Lipolase® as the other enzyme, and if the preparation is a granulate it has been found that the lipase exhibits an excellent stability.
- WO 89/08703 describes a method for production of crystalline subtilisin. This crystalline protease could be used as a constituent in the preparation according to the invention. However, WO 89/08703 does not indicate anything about the problems, which arise in relation to the preparations, which besides the crystalline subtilisin contain protease sensitive enzymes.
- the enzyme containing preparations according to the invention can be produced in any conventional manner, if only the conventional enzyme starting material, i.e. enzyme in the form of an amorphous powder, usually with a relatively large amount of impurities, or in the form of an enzyme solution or slurry, is substituted by an enzymatic starting material, in which substantially 100% of the enzymatic activity is present as enzyme crystals.
- the preparation is a granulate, a non limiting list of such usable granulation methods is the previously cited US 4,106,991, US 4,661,452, DOS 2,060,095, and Gb 1,362,365.
- a preferred form of enzyme crystals is described in co-pending patent applications Nos. 847/90 and 848/90 (our refs. 3411.010-DK and 3411.020), filed on the same date as this application.
- Other types of enzyme crystals usable in the enzyme containing preparation are known per se .
- a further advantage in relation to the preparation according to the invention is to be found in the washing process in a washing float with chlorine in the tap water.
- the chlorine will be consumed in the beginning of the washing cycle, and due to the fact that crystalline enzymes are dissolved slower in the washing float than enzymes usually used, the enzymes in the preparation according to the invention will not be present in dissolved form, before part of the chlorine has been consumed, and thus they will be protected from inactivation by the chlorine. Documentation for this will be presented later in this specification.
- the stabilizing agent for the enzymes provides a further improvement of the enzyme stability.
- PVP polyvinyl pyrrolidone
- sucrose and Ca+ + can be used as stabilizing agents.
- crystals possess a maximum crystal dimension between 0.1 ⁇ m and 500 ⁇ m, preferably between 1 ⁇ m and 100 ⁇ m.
- Such crystals are preferably prepared according to co-pending patent applications Nos. 847/90 and 848/90 (our refs. 3411.010-DK and 3411.020-DK), filed on the same date as this application, but they can also be prepared by means of other crystallization methods.
- the protease sensitive enzyme is a lipase, amylase, cellulase, hemicellulase, pectinase, amidase or oxidase, or protein engineered variants of these. These enzymes are common enzymes used as additives in detergents.
- the protease in the preparation according to the invention may be a Subtilisin type protease.

Abstract
Description
- The invention encompasses an enzyme containing preparation containing a protease and at least one other enzyme and a detergent containing such preparation. In this specification with claims the term "preparation" means either a granulate or a liquid slurry. The slurry can be either anhydrous or substantially anhydrous, or it can be aqueous. These enzyme containing preparations can be used in different fields, e.g. in the field comprising digestive aids and in the detergent field, but their main use is to be found in the detergent field.
- In this specification with claims the term "granulate" is to be understood in its widest sense comprising the entire scope from small particles with a size of the order of magnitude around 10 µm to tablets with a size of the order of magnitude around 1 cm.
- Enzyme containing granulates are widely used in industry, mainly as dust free additives to detergents. Reference can be made to e.g. US 4,106,991, US 4,661,452, DOS 2,060,095, and GB 1,362,365.
- One of the big problems in regard to protease containing granulates is the storage stability of other enzymes present in the granulate. Another big problem in regard to enzyme containing granulates is the storage stability of the enzymes when the enzyme containing granulate is mixed with the other detergent components. Even if several methods for stabilization of the enzymatic activity have been devised, the stability of the enzymatic activity in the enzyme granulate containing detergents is still open to improvement. Another problem in regard to enzyme containing granulates is the color, as most enzyme containing granulates will be discolored, if not coated with e.g. TiO₂. A third problem in regard to enzyme containing granulates is the smell thereof. Even after a fairly good purification of the enzyme containing fermentation broth the finished product often exhibits an unagreeable strong smell.
- Anhydrous or substantially anhydrous slurries are widely used in industry, mainly as additives to liquid detergents. Aqueous slurries can be used as additives to liquid detergents, in the starch industry and in the food industry. If the slurry is aqueous the water activity or the ionic strenght in the slurry has to be controlled in such manner that the entire amount or substantially the entire amount of the crystalline enzyme is maintained in the crystalline form.
- A big problem in relation to liquid detergents is the stability of enzymes added to these. Several stabilization systems have been used in an attempt to overcome this problem. Within the field of low pH formulations both calcium, formate and borate stabilization has been used and are used. Within the higher pH range some of the inhibition methods are also used. But especially within structured liquids a hydrophobic encapsulation has been used, vide Gb 2,186,884A. However, all these stabilization systems are open to improvement. Another big problem in regard to liquid, enzyme containing preparations is the color. Most liquid, enzyme containing preparations are colored due to impurities, usually with a dull, brownish color, and also, the color varies somewhat from batch to batch. This means that the manufacturer of liquid detergents will have to compensate for this color, when he wants to produce for instance a blue liquid detergent, and furthermore, this compensation may vary from batch to batch of the liquid enzyme containing preparation, which obviously is disadvantageous. As with granulates, also with liquid detergents the smell can be a problem.
- Also, some preparations contain allergy generating impurities, and thus, purer preparations is a desideratum.
- Thus the purpose of the invention is the provision of an enzyme containing preparation, which exhibits an improved stability, and which is colorless or almost colorless and of a high purity, and thus without any smell problems, and a detergent containing such enzyme containing preparation.
- The enzyme containing preparation according to the invention is characterized by the fact that it contains a protease and at least one protease sensitive enzyme, wherein substantially 100% of the proteolytic activity and/or substantially 100% of the protease sensitive enzyme or the protease sensitive enzymes are present as crystals, wherein more than 90% of the crystals possess a maximum crystal dimension between 0.01 µm and 500 µm, preferably between 0.1 µm and 100 µm, and that the preparation preferably contains a stabilizing agent for the enzymes.
- If the protease and the protease sensitive enzyme(s) originate from the same microorganism, the stability problems in regard to the protease sensitive enzyme(s) are usually minor. However, for various reasons, e.g. for economic reasons, the microorganism from which the protease is produced, usually differs from the microorganism(s), from which the protease sensitive enzyme(s) is (are) produced, and in such cases serious stability problems may occur. However, with the enzyme containing preparation according to the invention it surprisingly has been found that these stability problems are largely eliminated. Thus, surprisingly it has been found that the enzyme containing preparation according to the invention, when present in a detergent, possesses an equally good or better enzyme stability than otherwise similar but less pure enzyme containing preparations. It is normally assumed that some of the impurities from the fermentation broth stabilize the enzyme, and that consequently it would be a disadvantage in regard to enzyme stability to purify the enzyme too much, and this assumption is correct. However, if a pure enzyme can be maintained as crystals in the preparations according to the invention it has been found that the stability is almost equal to or better than the stability of less pure preparations. Also, it has been found that the enzyme containing preparation according to the invention possesses improved color and smell characteristics, when the crystallization of the enzyme is performed without later introduction of impurities.
- If substantially 100% of the proteolytic activity is present as crystals only a small amount of the crystalline protease or nothing thereof will be dissolved in the preparation according to the invention, and thus, the stability of the other enzyme or the other enzymes in the preparation according to the invention will be improved. If the protease is Savinase® and the preparation contains the lipase Lipolase® as the other enzyme, and if the preparation is a slurry it has been found that the lipase exhibits an excellent stability. If substantially 100% of the protease sensitive enzyme or the protease sensitive enzymes are present as crystals only a small amount of the protease sensitive enzyme(s) or nothing thereof will be dissolved in the preparation according to the invention, and thus, the stability of the protease sensitive enzyme(s) in the preparation according to the invention will be improved. If the protease is Savinase® and the preparation contains the lipase Lipolase® as the other enzyme, and if the preparation is a granulate it has been found that the lipase exhibits an excellent stability.
- WO 89/08703 describes a method for production of crystalline subtilisin. This crystalline protease could be used as a constituent in the preparation according to the invention. However, WO 89/08703 does not indicate anything about the problems, which arise in relation to the preparations, which besides the crystalline subtilisin contain protease sensitive enzymes.
- It is to be understood that the enzyme containing preparations according to the invention can be produced in any conventional manner, if only the conventional enzyme starting material, i.e. enzyme in the form of an amorphous powder, usually with a relatively large amount of impurities, or in the form of an enzyme solution or slurry, is substituted by an enzymatic starting material, in which substantially 100% of the enzymatic activity is present as enzyme crystals. If the preparation is a granulate, a non limiting list of such usable granulation methods is the previously cited US 4,106,991, US 4,661,452, DOS 2,060,095, and Gb 1,362,365.
- A preferred form of enzyme crystals is described in co-pending patent applications Nos. 847/90 and 848/90 (our refs. 3411.010-DK and 3411.020), filed on the same date as this application. Other types of enzyme crystals usable in the enzyme containing preparation are known per se. Reference can be made to DK 872/86, US 4,699,882, and Northrop, J.H. et al, Crystalline Enzymes, 2nd edition, New York, 1948. Also, reference can be made to the current catalogues from Sigma Chemical Company, P.O. Box 14508, St. Louis, MO, USA.
- A further advantage in relation to the preparation according to the invention is to be found in the washing process in a washing float with chlorine in the tap water. In such washing floats the chlorine will be consumed in the beginning of the washing cycle, and due to the fact that crystalline enzymes are dissolved slower in the washing float than enzymes usually used, the enzymes in the preparation according to the invention will not be present in dissolved form, before part of the chlorine has been consumed, and thus they will be protected from inactivation by the chlorine. Documentation for this will be presented later in this specification.
- The stabilizing agent for the enzymes provides a further improvement of the enzyme stability. In case of a granulate PVP (polyvinyl pyrrolidone) can be used; in case of a slurry preservatives against microbial growth, sucrose and Ca⁺ ⁺ can be used as stabilizing agents.
- In the preparation according to the invention more than 90% of the crystals possess a maximum crystal dimension between 0.1 µm and 500 µm, preferably between 1 µm and 100 µm. Such crystals are preferably prepared according to co-pending patent applications Nos. 847/90 and 848/90 (our refs. 3411.010-DK and 3411.020-DK), filed on the same date as this application, but they can also be prepared by means of other crystallization methods.
- In a preferred embodiment of the preparation according to the invention the protease sensitive enzyme is a lipase, amylase, cellulase, hemicellulase, pectinase, amidase or oxidase, or protein engineered variants of these. These enzymes are common enzymes used as additives in detergents.
- The protease in the preparation according to the invention may be a Subtilisin type protease. Examples are Savinase®, Esperase®, Alcalase®, Subtilisin NOVO or protein engineered variants of these. These enzymes are preferred proteases in detergents.
- In a preferred embodiment of the preparation according to the invention the protease sensitive enzyme is a lipase and the lipase is Lipolase®.
- The preparation according to the invention may be a granulate. This preparation is well suited as an additive to a detergent in granulate form.
- The preparation according to the invention may be a slurry, which may be anhydrous or substantially anhydrous, or aqueous.
- The preparation according to the invention may be used as a detergent additive. This is the main use of the preparation according to the invention.
- Also the invention comprises a detergent, which contains the preparation according to the invention, whereby the detergent either is solid and contains the preparation as a granulate in a concentration of between 0.001 and 10 mg of enzyme protein/g of detergent, preferably between 0.005 and 5 mg of enzyme protein/g of detergent, most preferably from 0.01 to 1 mg of enzyme protein/g of detergent, or is liquid and contains the preparation as an anhydrous or substantially anhydrous slurry in an amount of between 0.001 to 10 mg of enzyme protein per g of detergent, preferably from 0.005 to 5 mg of enzyme protein per g of detergent, most preferably from 0.01 to 1 mg of enzyme protein per g of detergent. Depending upon the enzymatic strength of the granulate the concentrations indicated above will usually be obtained by addition of between 0.01 and 10% w/w of the granulate to the detergent. The above indicated liquid detergents exhibit a satisfactory stability of the enzyme.
- Use of binders in relation to the granulate preparations according to the invention is a necessity, and optionally such binders can be carbohydrate binders, e.g. dextrins or cellulose derivatives, for instance hydroxypropyl cellulose, methyl cellulose or CMC.
