Definitions
- the present invention relates to a detergent composition.
- Detergent compositions ⁇ especially laundry detergents
- the functions have to be provided with a view to external considerations such as ease of use, formulation stability, and environmental considerations .
- liquid detergent composition comprising:
- PVP polyvinylpyrrolidone
- composition of the invention provides an excellent soil removal / suspension ability in a laundry washing operation. Without wishing to be limited by theory it is proposed that this effect arises due to a synergistic combination of the PVP and cellulase enzyme. Also the composition is unexpectedly advantageous in that it is readily biodegradable
- the invention is also directed (in a second aspect) to the use of the above-described compositions as a laundry detergent, detergent booster, stain treater, laundry detergent, etc.
- the use is particularly suited to the enhancement of soil suspending performance in a laundry washing operation.
- composition is free of polyacrylate polymer and / or carboxymethyl cellulose.
- composition is free of bleach and / or phos ⁇ phate based builders.
- composition comprises the cellulase enzyme in an amount of 0.1% to about 1% by weight, most preferably about 0.5% by weight.
- the cellulose enzyme comprises a cellulose enzyme supplied under the Trade Name Endolase ⁇ e.g. Endolase 5000L), (available from Novozymes) .
- the composition comprises the PVP in an amount of 0.1% to about 2% by weight, most preferably about 1.5% by- weight .
- the PVP has a molecular weight of about 40000.
- the PVP is supplied under the Trade Name Sokalan (e.g. Sokalan HP53) , ⁇ available from BASF).
- compositions suitable for use in the compositions include protease and amylase enzymes.
- the proteolytic enzymes suitable for the present compositions include the various commercial liquid enzyme preparations which have been adapted for use in association with detergent compositions. Enzyme preparations in powdered form are also useful although, as a general rule, less convenient for incorporation into liquid compositions. Suitable liquid enzyme preparations include "Alcalase”, “Savinase”, “Liquanase” and “Esperase”, all trademarked products sold by Novo Industries, Copenhagen, Denmark, and "Maxatase", “Maxacal”, “Purafect Prime” and “AZ-Protease” and “Properase” sold by Gist-Brocades, Delft, The Netherlands.
- alpha-amylase liquid enzyme preparations are those sold by Novo Industries and Gist-Brocades under the tradenames "Stainzyme”, “Termamyl” and “Maxamyl”, respectively .
- Mixtures of proteolytic and amylase enzymes can and often are used to assist in removal of different types of stains.
- the proteolytic enzyme and/or amylase enzyme will normally be present in the compositions in an effective amount in the range of from about 0.05% to about 5%, preferably from about 0.5% to about 2%, by weight of the composition. Generally, lower levels of amylase are required.
- a salt of the hydroxycarboxylic acid such as sodium citrate which is preferred because of its ready availability and contribution to improving physical to improving the physical stability of the composition - i.e., preventing phase separation, as well as providing efficacy against oxidizable stains, e.g., coffee and wine stains.
- hydroxycarboxylic acids such as malic acid, tartaric acid, isocitric acid or tri-hydroxyglutaric acid.
- the preferred sodium citrate is conveniently used in the form of its dihydrate .
- citric acid itself may be used in formulating the compositions.
- the hydroxydi- or hydroxytri-carboxylic acid will be present in its ionized salt state.
- This ingredient is used in an amount ranging of about 5% to about 20% of the entire enzyme-containing composition, preferably amounts of from 8% to 15%, and more preferably in amounts of from 10% to 13%.
- An alkali metal chloride preferably calcium chloride.

Abstract
A liquid detergent composition comprises: (a) from about 0.01% to about 5% by weight of a cellulase enzyme; and (b) from about 0.001% to about 5% by weight polyvinylpyrrolidone (PVP) or salt thereof, or mixtures thereof, wherein said polyvinylpyrrolidone or salts thereof have an average molecular weight of from 20000 to 60000.
Description
COMPOSITION
The present invention relates to a detergent composition.
Detergent compositions {especially laundry detergents) have to be able to provide many functions within the overall cleaning operation, such as soil removal, water softening, fabric softening and so on. Furthermore the functions have to be provided with a view to external considerations such as ease of use, formulation stability, and environmental considerations .
Of the external factors one of ever increasing importance is that of environmental considerations. The effect of household effluent discharges, even following processing, into water features such as rivers, lakes and seas can no longer be ignored.
However, the simple removal of some of components from the detergent formulation as a result of their detrimental environmental impact is no so straightforward. The loss of certain components cannot be readily tolerated due to the impact that such a loss leaves on the remaining formulation. This loss is generally reflected in overall poorer performance on certain aspects of the washing operation. Other negative factors (such as reduced stability) may also come into play.
The impact of these considerations is strongly felt in the area of soil suspension. This is a required / desired part of a laundry washing operation as soil suspension agents prevent the re-deposition of soils back onto the item {fabric) being cleaned. The simple removal of soil suspension agents is typically reflected in that the items being cleaned show a larger tendency towards graying / discoloration which is aesthetically unpleasing as well as being indicative of a poor cleaning operation.
An additional issue affecting the performance of laundry detergent is that of water consumption in domestic washing machines. The amount of water used in a typical wash cycle is continually being lowered for environmental and cost reasons (an increasing issue since most consumers are now charged per unit of water used) . More economical (in terms of water) laundry washing machines present a concern since the soil removed from the clothing being washed is more concentrated in the wash liquor and thus imparts a larger
re-deposition effect on clothing being washed. It is an escalating problem to address performance of laundry detergents with lower machine water consumption.
It is an object of the present invention to obviate / miti¬ gate the problems outlined above.
According to a first aspect of the invention there is provided a liquid detergent composition comprising:
(a) from about 0.01% to about 5% by weight of a cellulase enzyme; and
(b) from about 0.001% to about 5% by weight polyvinylpyrrolidone (PVP) or salt thereof, or mixtures thereof, wherein said polyvinylpyrrolidone or salts thereof have an average molecular weighl of from 20000 to 60000.
It has surprisingly been found that the composition of the invention provides an excellent soil removal / suspension ability in a laundry washing operation. Without wishing to be limited by theory it is proposed that this effect arises due to a synergistic combination of the PVP and cellulase enzyme. Also the composition is unexpectedly advantageous in that it is readily biodegradable
Further, the invention is also directed (in a second aspect) to the use of the above-described compositions as a laundry detergent, detergent booster, stain treater, laundry detergent, etc.
The use is particularly suited to the enhancement of soil suspending performance in a laundry washing operation.
Preferably the composition is free of polyacrylate polymer and / or carboxymethyl cellulose.
Preferably the composition is free of bleach and / or phos¬ phate based builders.
Generally the composition comprises the cellulase enzyme in an amount of 0.1% to about 1% by weight, most preferably about 0.5% by weight.
Preferably the cellulose enzyme comprises a cellulose enzyme supplied under the Trade Name Endolase {e.g. Endolase 5000L), (available from Novozymes) .
Generally the composition comprises the PVP in an amount of 0.1% to about 2% by weight, most preferably about 1.5% by- weight .
Preferably the PVP has a molecular weight of about 40000. Preferably the PVP is supplied under the Trade Name Sokalan (e.g. Sokalan HP53) , {available from BASF).
Additional Enzymes
Further enzymes suitable for use in the compositions include protease and amylase enzymes.
The proteolytic enzymes suitable for the present compositions include the various commercial liquid enzyme preparations which have been adapted for use in association with detergent compositions. Enzyme preparations in powdered form are also useful although, as a general rule, less convenient for incorporation into liquid compositions. Suitable liquid enzyme preparations include "Alcalase", "Savinase", "Liquanase" and "Esperase", all trademarked products sold by Novo Industries, Copenhagen, Denmark, and "Maxatase", "Maxacal", "Purafect Prime" and "AZ-Protease" and "Properase" sold by Gist-Brocades, Delft, The Netherlands.
Among the suitable alpha-amylase liquid enzyme preparations are those sold by Novo Industries and Gist-Brocades under the tradenames "Stainzyme", "Termamyl" and "Maxamyl", respectively .
Mixtures of proteolytic and amylase enzymes can and often are used to assist in removal of different types of stains.
The proteolytic enzyme and/or amylase enzyme will normally be present in the compositions in an effective amount in the range of from about 0.05% to about 5%, preferably from about 0.5% to about 2%, by weight of the composition. Generally, lower levels of amylase are required.
Enzyme Stabilisers
Preferably a salt of the hydroxycarboxylic acid such as sodium citrate which is preferred because of its ready availability and contribution to improving physical to improving the physical stability of the composition - i.e., preventing phase separation, as well as providing efficacy
against oxidizable stains, e.g., coffee and wine stains. However, other hydroxydi- or hydroxytri-carboxylic acids can be employed, such as malic acid, tartaric acid, isocitric acid or tri-hydroxyglutaric acid. The preferred sodium citrate is conveniently used in the form of its dihydrate . Alternatively, citric acid itself may be used in formulating the compositions. However, since the compositions are at an alkaline pH, the hydroxydi- or hydroxytri-carboxylic acid will be present in its ionized salt state. This ingredient is used in an amount ranging of about 5% to about 20% of the entire enzyme-containing composition, preferably amounts of from 8% to 15%, and more preferably in amounts of from 10% to 13%.
An alkali metal chloride, preferably calcium chloride. This ingredient is used in an amount of from about 2% to abυuL 15% based υii the weiyliL u£ Lhe enLiie enzyme- containing composition, preferably, the chloride ingredient is used in amounts ranging from 4% to 12%, and more preferably from 5% to 8%.
Surfactant
Preferably the composition contains from about 10% to about 20% of a nonionic surfactant. Preferred examples of nonionic surfactants include Cs-Cis alcohol alkoxylated with 5 to 7moles of ethylene oxide. A wide variety of alkoxylated fatty alcohols are known to the art and these vary considerably in HLB {hydrophile-lipophile balance) . For purposes of this invention, it is preferable to employ an alkoxylated alcohol which is relatively hydrophobic. Preferred surfactants are fatty alcohols having from about 8 about 15 carbon atoms, alkoxylated with about 5 to 7 moles of ethylene oxide.
