Int. Cl. ClZk 1/00 US. Cl. 195-63 11 Claims ABSTRACT OF THE DISCLOSURE Enzyme compositions of the type used in washing, namely, bacterial protease, bacterial amylase and mixtures thereof are prepared in the form of a dry-appearing, essentially non-dusting, flowable enzyme powder, free of gummy, sticky and lumpy characteristics and resistant to moisture.
BACKGROUND OF THE INVENTION In recent years the use of enzymes, especially bacterial protease for pre-soak and detergent washing products has greatly increased. These enzymes are now being produced in very high potency concentrations and handling problems have developed as a result of these high potency levels. Many individuals have found these enzymes to be a source of irritation. The problem is particularly acute in the manufacture and handling of the enzymes themselves and also in the handling of the enzymes in plants where they are formulated into various types of detergent products. The problem would be greatly alleviated if it were possible to produce a dust-free enzyme product.
OBJECTS One of the ojects of the present invention is to provide dry-appearing, essentially non-dusting, flowable enzyme powders free of gummy, sticky and lumpy characteristics comprising a finely divided solid enzyme of the type used in the preparation of pre-soak and detergent washing products, namely, bacterial protease, bacterial amylase and mixtures of bacterial protease and bacterial amylase.
A further object of the invention is to provide new and improved flowable enzyme powders of the type described by the use of readily available, inexpensive, non-toxic modifying ingredients.
Another object of the invention is to provide a new and improved process for producing dry-appearing, essentially non-dusting, flowable enzyme powders of the type described. Other objects will appear hereinafter.
GENERAL STATEMENT OF THE INVENTION In accordance with the invention a dry-appearing, essentially non-dusting, flowable enzyme powder free of gummy, sticky, and lumpy characteristics comprising a finely divided solid enzyme from the group consisting of bacterial protease, bacterial amylase and mixtures of bacterial protease and bacterial amylase with or without other ingredients, as, for example, calcium acetate monohydrate, sodium sulfite, sodium sulfate, sodium tripolyphosphate, calcium carbonate and monocalcium phosphate, is prepared by intimately mixing with said enzyme with or without said other ingredients a dust and moisture inhibiting substance in the form of petrolatum or petrolatum liquid, or mixtures of petrolatum and petrolatum liquid, in an amount suflicient to reduce the dusting characteristic and impart protection against moisture but insuflicient to produce gummy, sticky and lumpy characteristics and interfere with flowability.
Patented June 5, 1973 The terms petrolatum and petrolatum liquid as used herein are defined in the Merck Index, 8th edition, page 800. A preferred type of petrolatum liquid is a mineral oil having a Sayboldt viscosity of 65/75 at F. (37.8 C.). The same product is available in a range of Saybolt viscosity of 48/52 to /155, as well as a viscosity of 180/190. Hence, a general range of viscosity is from 48 to 190. The petrolatum is a yellowish to light amber or white, semi-solid, unctuous jelly. Either or both of these types of substances and mixtures thereof are effective for the purpose of the invention. The amounts required are normally within the range of 1% to 10% of the weight of the enzymes and a preferred range is 3% to 8% by weight of the enzymes.
The protease of the enzymes is defined in terms of PV units per gram for bacterial protease and DV units per gram for bacterial amylase. The PV activity of the bacterial protease will usually be within the range of 15,000 to 1,000,000 PV units per gram and the potency of the bacterial amylase will usually be within the range of 30 to 100,000 DV units per gram. In some enzyme compositions the amount of bacterial amylase is not significant.
The dust and moisture inhibiting petrolatum and petrolatum liquid or mixtures thereof can be used to prepare non-dusting, flowable enzyme powders consisting essentially of the enzymes per se. They can also be used to prepare enzyme compositions which are essentially dryappearing, non-dusting and flowable and contain diluents such as, for example, calcium acetate monohydrate, sodium sulfite, sodium sulfate, sodium tripolyphosphate, calcium carbonate and monocalcium phosphate. In some cases other substances can be added for special purposes.
DETAILED DESCRIPTION OF THE INVENTION In preparing compositions in accordance with the invention several different methods were used as follows:
(A) Mineral oil was blended at ordinary temperatures and pressures either as such or as a fine spray with the finely divided enzyme either alone or mixed with other ingredients;
(B) Mineral oil was blended with a mixture of the enzyme and other ingredients, except sodium sulfate and sodium sulfate was intimately mixed with the resultant product after the mineral oil addition;
(C) Mineral oil was blended vw'th the enzyme and other ingredients except calcium acetate and sodium sulfate and calcium acetate and sodium sulfate were intimately mixed with the resultant composition after the mineral oil addition; and
(D) The enzyme with or without other ingredients was prewarmed to a temperature of about 50 C. and then slowly intimately mixed vw'th a warm solution of petrolatum or a mixture of petrolatum and petrolatum liquid which had been previously warmed to about 50 C. After all of the petrolatum or petrolatum liquid had been added, blending Was continued until the mixture was uniform while allowing it to cool.
In some cases the mixture was ground during and after the addition of the petrolatum and/or petrolatum liquid to a desired particle size, for example, a size sufficient to pass a 325 mesh sieve.
In the following tables in which the quantities are given in parts by weight unless otherwise indicated, calcium acetate monohydrate is symbolized by Ca(OAc) sodium tripolyphosphate by STP, sodium sulfite by Na SO zinc oxide by ZnO, sodium sulfate by Na SO calcium carbonate by CaCO and monocalcium phosphate by MCP. The method of addition is given in the last column of each table.
teristics consisting essentially of a finely divided solid enzyme from the group consisting of bacterial protease, bacterial amylase and mixtures of bacterial protease and bacterial amylase, intimately mixed with a dust and moisture inhibiting substance from the group consisting of petrolatum, petrolatum liquid and mixtures thereof in an amount sufiicient to reduce the dusting characteristic and impart protection against moisture but insufiicient to produce gummy, sticky and lumpy characteristics and interfere with flowability.
2. A composition as claimed in claim 1 in which said dust and moisture inhibiting substance is petrolatum.
3. A composition as claimed in claim 1 in which said dust and moisture inhibiting substance is petrolatum liquid.
