Description

DETERGENT COMPOSITIONS COMPRISING IMPROVED AMYLASE FOR DINGY FABRIC CLEAN-UP

TECHNICAL FIELD

The present invention relates to the use of a specific amylase enzyme in laundry detergent compositions for boosting fabric laundry performance, especially on dingy stains and soils.

BACKGROUND OF THE INVENTION

For a number of years amylase enzymes have been used for a variety of different purposes, the most important of which are starch liquefaction, textile desizing, starch modification in the paper and pulp industry, and for brewing and baking. A further use of amylases which is becoming increasingly important, is the removal of starch containing soils and stains during the washing of fabrics, hard surfaces and dishes. Indeed, amylase enzymes have long been recognised in dishwashing, hard surface cleaning and laundry compositions to provide the removal of starchy food residues or starchy films from dishware, flatware, glasses and hard surfaces or to provide cleaning performance on starchy soils as well as other soils typically encountered in laundry applications.

WO/94/02597, Novo Nordisk A/S published February 03, 1994, describes cleaning compositions which incorporate mutant amylases. See also W094/18314 Genencor, published August 18, 1994; O96/05295, Genencor published February 22, 1996 and O/95/10603, Novo Nordisk A/S, published April 20, 1995.

Other amylases known for use in cleaning compositions include both α- and β-amylases. α-Amylases are known in the art and include those disclosed in US Pat. no. 5,003,257; EP 252,666; O/91/00353; FR 2,676,456; EP 285,123; EP 525,610; EP 368,341; and British Patent specification no. 1,296,839 (Novo).

Examples of commercial α-amylases products are

Termamyl® Ban® Duramyl® and Fungamyl®, all available from

Novo Nordisk A/S Denmark and Maxamyl® available from Gist Brocades and Purafact Ox Am® from Genencor.

Recently new amylases have been identified and are described in WO/95/26397, Novo Nordisk A/S, published October 05, 1995, disclosing an α-amylase having a specific activity at least 25% higher than the specific activity of Termamyl® at a temperature range of 25°C to 55°C and at a pH value in the range of 8 to 10. Variants of these new amylases demonstrating at least one of the following properties relative to the parent enzymes : 1) improved thermal stability, 2) oxidation stability and 3) reduced calcium ion dependency properties. Examples of other desirable improvements or modifications of properties (relative to the parent-α-amylase) which may be achieved with a variant according to the present invention are : increased stability and/or α-amylolytic activity at neutral to relatively high pH values, increased α-amylolytic activity at relatively high temperature and increase or decrease of the isoelectric point (pi) so as to better match the pi value for α-amylase variant to the pH of the medium, have been described in the co-pending application by Novo Nordisk PCT/DK96/00056, and are hereinafter referred as "specific amylase".

Therefore, while amylase is known to act on starchy stains, there remains a substantial technical challenge in formulating laundry components comprising specific amylase in such a manner as to meet the consumer's need for superior cleaning performance on starchy soils as well as other soils typically encountered in laundry applications. Moreover, such detergent compositions must provide an excellent value and a safe, environmentally acceptable product which leaves laundered fabrics, especially those particularly prone to dingy soiling, in dingy-free and undamaged condition. A need therefore exists for the development of detergent compositions comprising specific amylase enzymes designed to be especially effective at dingy clean up.

It has been surprisingly found that specific amylase enzymes provide unexpected superior dingy clean up, whiteness maintenance and overall cleaning performance. Such performance is illustrated but not limited to excellent dingy soil removal present e.g. on pillow cases, T-shirts and sock bottoms.

It is therefore an object of the present invention to provide effective dingy stain removal and overall cleaning benefits through laundry compositions containing specific amylase. SUMMARY OF THE INVENTION

This invention relates to the use of a specific amylase in a laundry detergent composition to provide especially effective surface cleaning of textiles.

The present invention relates to the laundering of fabrics to maintain or increase whiteness and provide dingy clean up, by contacting fabrics in need of whiteness and/or dingy clean up with an aqueous solution formed from a detergent composition comprising a specific amylase at a concentration and for a sufficient period such that the dingy cleaning performance of said composition is increased.

DETAILED DESCRIPTION OF THE INVENTION

Without limitation by theory, it is believed that dingy soils and stains are the result of combinations of various types of soils. For instance, fatty soils comprise lipids, proteins and pigments that are deposited on fabrics from contact with human or animal skin. The majority of lipids are secreted from the sebaceous gland as sebum. Proteins and pigments from skin fragments are liberated by the breakdown of skin cells. It is believed that sebum is the major soil present on laundry and its removal is important because unremoved fat acts as a matrix to hold particulate soils. It is further believed that compounds present in the sebum oxidise to contribute to the yellowing of the fabrics. Particulate soils comprise mostly airborne soil and floor/ground dust and include topsoil and products produced during the incomplete combustion of petroleum products. "Dingy clean up" means the ability of a detergent composition to remove such dingy soil built-up, over one or more washes, resulting in a measurable improvement in fabric appearance. Whiteness maintenance is the monitoring of the whiteness of wash & wear fabrics over a number of washing cycles. A good performing detergent has a good whiteness maintenance profile, i.e. it ensures that the whiteness of the washed fabrics is maintained at a high level during the complete life cycle of washing & wearing.

Specific Amylase Enzymes

An essential component of the detergent compositions of the present invention is a specific amylase enzyme. Such specific amylase enzymes include those described m W095/26397 and in co-pending application by Novo Nordisk PCT/DK96/00056. These enzymes are incorporated into detergent compositions at a level from 0.0001° to 0.1% pure enzyme by weight of the total composition, preferably at a level of from 0.00018% to 0.060%, more preferably from 0.00024% to 0.048% pure enzyme by weight of total weight composition.

Specific amylase enzymes for use in the detergent compositions of the present invention therefore include :

(a) α-amylases characterised by having a specific activity at least 25% higher than the specific activity of Termamyl® at a temperature range of 25°C to 55°C and at a pH value in the range of 8 to 10, measured by the Phadebas® α-amylase activity assay. Such Phadebas® α-amylase activity assay is described at pages 9-10, W095/26397.

(b) α-amylases according (a) comprising the amino sequence shown in SEQ ID No. 1 or an α-amylase being at least 80% homologous with the amino acid sequence shown in SEQ ID No.l.

A polypeptide is considered to be X% homologous to the parent amylase if a comparison of the respective amino acid sequences, performed via algorithms, such as the one described by Lip an and Pearson in Science 227, 1985, p. 1435, reveals an identity of X%

(e) α-amylases according (a-d) wherein the α-amylase is obtainable from an alkalophilic Bacillus species; and in particular, from any of the strains NCIB 12289, NCIB 12512, NCIB 12513 and DSM 935.

In the context of the present invention, the term "obtainable from" is intended not only to indicate an amylase produced by a Bacillus strain but also an amylase encoded by a DNA sequence isolated from such a Bacillus strain and produced in an host organism transformed with said DNA sequence.

(f) α-amylase showing positive immunological cross- reactivity with antibodies raised against an α-amylase having an amino acid sequence corresponding respectively to SEQ ID No.l, ID No .2 or ID No .3.

(g) Variants of the following parent α-amylases which (i) have one of the amino acid sequences shown in SEQ ID No.l, ID No.2 or ID No.4 respectively, or (ii)displays at least 80% homology with one or more of said amino acid sequences, and/or displays immunological cross-reactivity with an antibody raised against an α-amylase having one of said amino acid sequences, and/or is encoded by a DNA sequence wich hybridizes with the same probe as a DNA sequence encoding an α-amylase having one of said amino acid sequence; in which variants :

1. at least one amino acid residue of said parent α-amylase has been deleted; and/or

2. at least one amino acid residue of said parent α-amylase has been replaced by a different amino acid residue; and/or

3. at least one amino acid residue has been inserted relative to said parent α-amylase; said variant having an α-amylase activity and exhibiting at least one of the following properties relative to said parent α-amylase : increased thermostability, increased stability towards oxidation, reduced Ca ion dependency, increased stability and/or α-amylolytic activity at neutral to relatively high pH values, increased α-amylolytic activity at relatively high temperature and increase or decrease of the isoelectric point (pi) so as to better match the pi value for α-amylase variant to the pH of the medium.

Said variants are described in the co-pending patent application PCT/DK96/00056.

The hydrophobic portion of these compounds will preferably have a molecular weight of from about 1500 to about 1800 and will exhibit water insolubility. The addition of polyoxyethylene moieties to this hydrophobic portion tends to increase the water solubility of the molecule as a whole, and the liquid character of the product is retained up to the point where the polyoxyethylene content is about 50% of the total weight of the condensation product, which corresponds to condensation with up to about 40 moles of ethylene oxide. Examples of compounds of this type include certain of the commercially- available Pluronic™ surfactants, marketed by BASF.
