Description

Cleaning compositions comprising enzymes

Reference to sequence listing

The present patent application contains a sequence listing in computer-readable format, which is incorporated herein by reference.

Technical Field

The present disclosure relates to cleaning compositions comprising specific glycoside hydrolases. The present disclosure also relates to methods of making and using such cleaning compositions. The disclosure also relates to the use of glycoside hydrolases.

Background

Detergent formulators are continually aiming to improve the performance of detergent compositions. One particular challenge is the removal of certain microbial-derived soils from surfaces such as textiles. Such soils can be sticky and difficult to remove. Furthermore, because they are sticky, they tend to adhere body soils and/or particulate soils to surfaces, making soil removal difficult and having a tendency to accumulate over time. This can be particularly pronounced, for example, on collars and cuffs that may not be completely clean.

There is a need for improved cleaning compositions that provide such soil cleaning. The inventors have found that this problem can be ameliorated by cleaning compositions comprising certain glycoside hydrolases. Glycosyl hydrolases are enzymes that catalyze the hydrolysis of glycosyl bonds to release smaller sugars. There are more than 100 glycosyl hydrolases and many different enzymes belong to the glycosyl hydrolases class, e.g. cellulases and xyloglucanases useful in cleaning compositions. Surprisingly, certain specific glycosyl hydrolases can provide particularly improved cleaning.

Glycoside hydrolases are described by Coutinho, P.M. and Henrissat, B.in "Recent Advances In Carbohydrate Bioengineering", edited by H.J.Gilbert, G.Davies, B.Henrissat and B.Svensson, the royal chemical society, Cambridge, 1999 on pages 3-12, Carbohydrate-active enzymes, an integrated database approach.

Such a solution, dispersion or suspension would be acceptably phase stable. When in liquid form, the detergents of the invention preferably have a viscosity of from 1 to 1500 cps (1 to 1500mPa · s), more preferably from 100 to 1000cps (100 to 1000mPa · s), and most preferably from 200 to 500cps (200 to 500mPa · s) at 20s "1 and 21 ℃.

The high shear viscosity at 20s-1 and the low shear viscosity at 0.05-1 can be obtained by scanning at 21C over a period of 3 minutes from a logarithmic shear rate of 0.1-1 to 25-1. Wherein the preferred rheology described herein can be achieved using either internal existing structuring with detergent ingredients or by employing external rheology modifiers. More preferably, the detergent, such as a detergent liquid composition, has a high shear rate viscosity of from about 100 to 1500 cps, more preferably from 100 to 1000 cps.

The cleaning and/or treatment compositions herein in liquid form can be prepared by combining the components of the cleaning and/or treatment compositions herein in any convenient order, and by mixing, e.g., stirring, the resulting combination of components to form a phase stable liquid detergent composition. In the process for preparing such compositions, a liquid matrix is formed containing at least a majority, or even substantially all, of the liquid components, e.g., nonionic surfactant, non-surface active liquid carrier, and other optional liquid components, while thoroughly mixing the liquid components by applying shear agitation to the liquid combination. For example, rapid stirring with a mechanical stirrer may be effectively employed. Substantially all of any anionic surfactant and ingredients in solid form may be added while maintaining shear agitation. Agitation of the mixture is continued and, if desired, can be enhanced at this point to form a solution or homogeneous dispersion of insoluble solid phase particles within the liquid phase. After some or all of the solid form material has been added to the agitated mixture, any particles of enzyme material, such as enzyme particles, to be included may be incorporated. As a variation of the composition preparation procedure described above, one or more of the solid components may be added to the agitated mixture as a slurry of a solution or granules premixed with a minor portion of one or more of the liquid components. After all composition components are added, the mixture is continued to be stirred for a period of time sufficient to form a composition having the desired viscosity and phase stability characteristics. Typically, this will involve a period of agitation of about 30 to 60 minutes.

The adjunct ingredients of the compositions of the present invention may be incorporated into the compositions as the product of a synthesis to produce such components, with or without intermediate purification steps. In the absence of a purification step, the mixture generally used will comprise the desired component or mixture thereof (and unless otherwise indicated, the percentages given herein relate to the weight percent of the component itself), and in addition, unreacted starting materials and impurities formed by side reactions and/or incomplete reactions.
