Definitions

  • the present invention relates to a fabric conditioner composition and, in particular, to a solid fabric conditioner composition, for instance in the form of a powder or tablet.
  • WO-A-91/13136 Novo Nordisk A/S discloses liquid fabric conditioner compositions comprising a lipase and/or a cellulase and/or a protease and/or an amylase. This document makes a passing reference to the possibility that enzymes may be included in solid rinsing agents.
  • more effective lipase deposition may be achieved from the rinse than from the wash.
  • the rinse is unbuilt and free calcium and magnesium enhance lipase adsorption.
  • typical rinse conditioner cationic actives are less inhibitory to lipase adsorption than are the anionic and nonionic actives found in main wash products.
  • liquid (aqueous) fabric softener compositions including lipase.
  • liquid rinse conditioners must have a pH of at least 5 to ensure satisfactory lipase stability. When the compositions are stored at pH's close to neutral then there can be problems with bacterial growth.
  • lipases promote the hydrolysis of certain fabric conditioner compounds, such as those containing ester groups, so that formulations of such fabric conditioners will be prone to decomposition through hydrolysis.
  • a solid fabric conditioner composition for use in the rinse step of a fabric washing process comprising a lipase, a dispersing aid and characterised in that it further comprises a fabric conditioning compound comprising a quaternary ammonium compound having a solubility in water at pH 2.5 and 20°C of less than 10g/l and in which the quaternary ammonium group is linked to at least one hydrocarbyl via an ester link.
  • Suitable fabric conditioning compounds will be apparent to those of skill in the art.
  • Highly preferred materials are cationic quaternary ammonium salts having two long hydrocarbyl chains, for instance two C 8-28 , preferably C 12-24 , hydrocarbyl chains.
  • the hydrocarbyl groups are alkyl or alkenyl groups, which are optionally substituted or interrupted by other groups.
  • the quaternary ammonium compound may be an ester-linked quaternary ammonium compound represented by the formula: wherein each R 5 group is independently selected from C 1-4 hydrocarbyl, such as alkyl, alkenyl or hydroxyalkyl groups; and wherein each R 6 group is independently selected from C 8-28 hydrocarbyl, such as alkyl or alkenyl groups;
  • a preferred material of this type is that of formula: wherein each R 7 is a long chain alkyl or alkenyl group such as tallow and Y - is as defined above and, in particular, is methosulphate.
  • a material having R 7 of tallow and Y - of methosulphate is available from Stepan under the trade name Stepantex VRH 90.
  • Another example of a suitable material of formula (III) has R 7 of partially hardened tallow and Y - of methosulphate.
  • R17 is a long chain alkyl or alkenyl group such as tallow, or partially hardened tallow.
  • Preferred choices of Y - are chloride or methosulphate.
  • ester-linked quaternary ammonium compounds which may be used in the compositions of the present invention are those of formula: wherein each R 8 is independently selected from C 1-4 hydrocarbyl, such as alkyl, alkenyl or hydroxyalkyl groups; and each R 9 is independently selected from C 8-28 hydrocarbyl, such as alkyl and alkenyl groups; n is an integer of from 0-5; and Y - is an anion preferably selected from halide, methosulphate and ethylsulphate radicals.
  • Preferred materials of this class and their method of preparation are, for example, described in US-A-4137180 (LEVER BROTHERS).
  • these materials comprise small amounts of the corresponding monoester as described in US-A-4137180 for example 1-tallowoxy, 2-hydroxy trimethyl ammonium propane chloride.
  • Compositions of the present invention preferably include 10 to 95% by weight of a quaternary ammonium fabric conditioning compound, particularly preferably 20 to 80% by weight.
  • the amount of fabric conditioning compound included in the composition may vary depending on the particular type of softener employed and on whether it is for use as a powder or tablet.
  • the conditioning compound having one of formulae (II), (III) or (IV) above may be included in powders in relatively large amounts, for instance between 60 and 95% by weight, preferably 70 to 90%.
  • the ester-linked softener is included in a tablet composition, it will generally be included in smaller amounts such as 10 to 40% by weight, preferably 15 to 30% by weight.
  • Fabric softeners which are readily dispersible in water may be included in larger proportions than those which are less readily dispersible.
  • Compositions of the invention preferably contain, in addition to a cationic material having a solubility in water at pH 2.5 and 20°C of less than 10g/l, an amount (preferably less than 50% by weight) of a cationic surfactant whose solubility in water at pH 2.5 and 20°C exceeds 10g/l.
  • a cationic surfactant include quaternary ammonium compounds in which the quaternary nitrogen atom carries a single long hydrocarbyl (e.g. alkyl or alkenyl) group, for example containing from 8 to 28, preferably 12 to 24 carbon atoms.
  • Examples include compounds of formula (VI) : where each R 15 is independently selected from substituted or unsubstituted alkyl or alkenyl groups having from 1 to 6 carbon atoms, R 16 is a substituted or unsubstituted alkyl or alkenyl group having from 8 to 28 carbon atoms, and B - is an anion, preferably a halide, methosulphate or ethosulphate.
  • Cationic materials having solubilities in excess of 10g/l under the conditions specified above assist in the dispersion of the less soluble cationic component.
  • Preferred examples of such compounds include cocobenzyldimethylammonium chloride, cocotrimethylammonium chloride, tallowtrimethylammonium chloride and dodecylbenzyldimethylammonium chloride (sold under the trade name Arquad 12).
  • high solubility cationic materials are preferably included in amounts not greater than 50% by weight of the composition, especially not greater than 30% by weight of the composition, and particularly preferably are included in amounts of from 5 to 20% by weight.
  • the cationic having a solubility of less than 10g/l and the cationic having a solubility in excess of 10g/l are present in a ratio by weight in the range 20:1 to 1:1, preferably 10:1 to 2:1 and particularly preferably 5:1 to 3:1.
  • the amount of lipase enzyme in the fabric conditioning composition may be chosen such that, on dilution, the concentration of enzyme in the rinse liquor is in the range of 0.0002 to 5mg preferably 0.002 to 2mg pure enzyme protein per litre of rinse liquor. Consequently, the concentration of enzyme in the composition prior to dilution generally lies in the range 2x10 -8 to 1 weight percent, preferably 2x10 -7 to 10 -1 weight percent, particularly preferably 2x10 -6 to 10 -2 weight percent.
  • compositions of the invention also include a dispersing agent for assisting the dispersion of the fabric conditioner compound in water.
  • Suitable dispersing agents will be apparent to those of skill in the art and include nonionic materials such as alkoxylated fatty alcohols, preferably containing a fatty alcohol having from 8 to 28 carbon atoms, the alcohol being ethoxylated with 2 to 50, preferably from 4 to 40 ethoxy groups.
  • a suitable nonionic is cocoalcohol 20E0; this is particularly suitable for use in conjunction with ester-linked fabric conditioning compounds such as those of formula (IV) above.
  • Electrolytes are suitable, for example, for use in conjunction with fabric conditioning compounds of formula (I) above.
  • the amount and type of dispersing agent used will depend on the amount and type of fabric conditioner compound employed as well as on the form of the composition (eg. whether powder or tablet). Thus, the amount of dispersing agent, where present, may vary between 1 and 90%, preferably 4 to 80%.
  • electrolytic dispersing agents which are preferably employed to disperse the less readily dispersible cationic fabric conditioning compounds, will be present in larger proportions such as 50 to 90% by weight, preferably 60 to 80% by weight, than will dispersing aids of the nonionic type which are typically employed in dispersions of the more readily water dispersible conditioning compounds, and are generally present in amounts of 2 to 15% preferably 4 to 10% by weight.
  • compositions currently on the market contain urea as a dispersing aid.
  • this material is unsuitable as a dispersing aid in solid fabric softener compositions containing enzymes, because of adverse effects on storage stability of the enzyme. Consequently, compositions of the invention preferably contain not more than 10% by weight urea, especially preferably not more than 5% by weight and most preferably not more than 1% by weight. Ideally, the compositions contain substantially no urea.
  • compositions may contain not more than 10% by weight solvent, preferably not more than 5% by weight solvent, particularly preferably not more than 1% and, most preferably contain substantially no solvent.
  • solvents which may be present in compositions of the present invention, because of incidental presence in raw materials, deliberate addition, or absorption from the surroundings include water and alcohols such as isopropyl alcohol and ethanol, glycerol, propylene glycol.
  • compositions of the invention may be in the form of powders (e.g. granules) or tablets. Such compositions may be prepared by conventional techniques. For example, powders may be prepared by sieving and mixing the components. Components which are included in small amounts, such as the enzyme, are preferably added on an inert carrier, for example on a silicate such as Microsil TM .
  • the carrier may account for up to 10% by weight of the composition, preferably not more than 5% by weight.
  • Tablets may be prepared by compression of a powdered composition. Tablets preferably contain at least 60% of an electrolyte such as sodium bicarbonate as a dispersing aid.
  • an electrolyte such as sodium bicarbonate
  • compositions of the invention may also contain other optional ingredients such as perfumes, perfume carriers, fluorescers, colourants, hydrotropes, antifoaming agents, antiredeposition agents, optical brightening agents, anti-shrinking agents, anti-wrinkle agents, fabric crisping agents, anti-spotting agents, soil-release agents, germicides, linear or branched silicones, fungicides, antioxidants, anti-corrosion agents, preservatives such as Proxel, ascorbic acid, Bronopol (Trade Mark), a commercially available form of 2-bromo-2-nitropropane-1,2-diol, dyes, bleaches and bleach precursors, drape imparting agents, antistatic agents and ironing aids.
  • perfumes perfume carriers, fluorescers, colourants, hydrotropes, antifoaming agents, antiredeposition agents, optical brightening agents, anti-shrinking agents, anti-wrinkle agents, fabric crisping agents, anti-spotting agents, soil-release agents, germicides
