Definitions
- the present invention relates to a fabric softening composition and to a method for its preparation. Specifically, the present invention relates to a fabric softening composition for use in the rinse step of a fabric washing process.
- EP-A-0,240,727 (Henkel) describes a softening composition including a quaternary ammonium compound having two 2-acyloxyalkyl groups, together with an alkali metal soap or the corresponding fatty acid.
- the quaternary ammonium compounds which it specifically discloses do not include the softening materials used in the present invention.
- EP-A-0,302,567 (Procter and Gamble) describes a method for preparing a fabric softener by combining a C1-C4 monohydric alcohol with a quaternary ammonium compound including two ester groups. Again, the quaternary ammonium compound is not of the type used in the present invention.
- the document refers to the possibility of adding a fatty acid to the softening composition, as a viscosity control agent.
- EP-A-0,122,141 (Unilever) relates to a softening composition including a water-insoluble cationic softener and a nonionic material which may be a C8-C24 fatty acid.
- the cationic softeners referred to do not include those used in the present invention.
- GB-A-2,039,556 (Unilever) describes a softening composition which includes a quaternary ammonium softener (substituted only with alkyl or alkenyl groups) and a C8-C24 carboxylic acid.
- the present invention relates to a fabric softening composition
- a fabric softening composition comprising:
- Preferred materials of this class and their method of preparation are, for example, described in US 4 137 180 (LEVER BROTHERS).
- these materials comprise small amounts of the corresponding monoester as described in US 4 137 180 for example 1-tallowoxy, 2-hydroxy trimethyl ammonium propane chloride.
- the level of ester-linked quaternary ammonium compounds is at least 1% by weight of the composition, more preferably more than 3% by weight of the composition; especially interesting are compositions of high active level, e.g. which comprise more than 8% of the ester-linked quaternary ammonium compound.
- the level of ester-linked quaternary ammonium compounds preferably is less than 70% by weight of the composition, more preferably less than 50%, typically from 3 to 30% by weight of the composition.
- the fatty acid material or salt thereof can be any mono-, di- or tri-carboxylic acid comprising an alkyl or alkenyl chain having from 8 to 28 carbon atoms or salts thereof.
- Preferred fatty acid materials or their salts may be represented by the formula: R1COOR2 wherein R1 is a straight or branched alkyl or alkenyl chain having from 8 to 28 carbon atoms, and wherein R2 is hydrogen or a cation.
- Preferred cations are alkali metal ions or alkali earth metal ions; more preferred are sodium, potassium or calcium.
- a non-saponified fatty acid material is particularly preferred.
- the level of fatty acid material is more than 0.1% by weight of the composition, more preferably more than 0.2%; especially preferred are concentrated systems comprising more than 0.5% of fatty acid material.
- the level of fatty acid material will usually not exceed 50% by weight of the composition, more preferably the level of fatty acid material is less than 30%, typically from 0.5 to 10% by weight of the composition.
- the weight ratio of ester-linked quaternary ammonium materials to fatty acid materials is preferably from 10:1 to 1:10, more preferably from 8:1 to 1:1, especially preferably from 7:1 to 3:1.
- compositions of the invention preferably have a pH of more than 2.0.
- the pH is preferably less than 5.0 to prevent saponification of the fatty acids.
- the pH is 5.0 or more, more preferably between 5.0 and 8.0.
- compositions of the invention may, in addition to the above described two ingredients, also comprise other active ingredients such as further fabric conditioning materials.
- compositions of the invention do not comprise large amounts of conventional non-ester-linked quaternary ammonium comounds, more preferably the compositions of the invention are substantially free of these quaternary ammonium compounds.
- Suitable conditioning materials for inclusion in compositions of the invention comprise nonionic materials.
- Suitable nonionic fabric softening agents include glycerol esters, such as glycerol monostearate, fatty alcohols, such as stearyl alcohol, alkoxylated fatty alcohols, C9-C24 fatty acids and lanolin and derivatives thereof.
- Suitable materials are disclosed in European Patent Applications 88 520 (Unilever PLC/NV - Case C1325), 122 141 (Unilever PLC/NC - Case C1363) and 79 746 (Procter & Gamble).
- softening materials which may be incorporated in a composition of the invention are amines, such as, for instance, described in EP 89200545.5, or biodegradable amphoteric softening materials such as, for instance, described in EP 89200113.2.
- the amount of softening materials other than the above mentioned ester-linked materials and fatty acid materials is relatively low, i.e. the weight ratio of other softener materials to the total of the two essential softener components is preferably less than 2:1; more preferably less than 1:1, most preferably less than 0.5:1.
- the composition can also contain one or more optional ingredients selected from non-aqueous solvents such as C1-C4 alkanols and polyhydric alcohols, pH buffering agents such as strong or weak acids, e.g. HCl, H2SO4, phosphoric, benzoic or citric acids, rewetting agents, viscosity modifiers such as electrolytes, for example calcium chloride, anti-gelling agents, perfumes, perfume carriers, fluorescers, colourants, hydrotropes, anti-foaming agents, anti-redeposition agents, enzymes, optical brightening agents, opacifiers, stabilizers such as guar gum and polyethylene glycol, emulsifiers, anti-shrinking agents, anti-wrinkle agents, fabric crisping agents, anti-spotting agents, soil-release agents, germicides, linear or branched silicones, fungicides, anti-oxidants, anti-corrosion agents, preservatives such as Bronopol (Trade Mark), a commercially available form
- These optional ingredients are preferably present at levels up to 5% by weight of the composition.
- the liquid compositions according to the invention may be prepared by a variety of methods.
- One suitable method is to form a molten mixture of the ester-linked quaternary ammonium materials and the fatty acid materials, optionally in combination with other softening materials, and adding this premix to water with stirring to form a dispersion and thereafter adding any other optional ingredients.
- the fabric conditioning composition of the invention may be added to a large volume of water to form a liquor with which the fabrics to be treated are contacted.
- the total concentration of the ester-linked quaternary ammonium compound and the fatty acid compound in this liquor will be between about 30 ppm and 1000 ppm.
- the weight ratio of the fabrics to the liquor will generally be between 1:1 and 1:20.
- composition D is a commercially available fabric conditioner (COCCOLINO CONCENTRATE).
- COCCOLINO CONCENTRATE a commercially available fabric conditioner
- compositions of 0.89 were requried for a 95% significance.
- composition F compared to compositions D and E.
- ester-linked quaternary ammonium materials suitable for use in compositions according to the invention are more biodegradable than quaternary ammonium materials which are more generally used.
