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.
  • each R 1 group is independently selected from C 1-4 alkyl, alkenyl or hydroxyalkyl groups; each R 2 group is independently selected from C12-24 alkyl or alkenyl groups;
  • ester-linked quaternary ammonium materials are particularly preferred for use in fabric conditioners because they are more biodegradable than conventional quaternary ammonium materials.
  • the present invention relates to a fabric softening composition which comprises:
  • compositions of the invention may take a variety of forms such as pastes, liquids etc and also they may be impregnated onto substrates for example for use in tumble dryers.
  • compositions of the invention are liquids, comprising an aqueous base, wherein the active ingredients are dispersed.
  • Suitable ester-linked quaternary ammonium materials (i) and their method of preparation are for example described in US 4 137 180 (LEVER BROTHERS).
  • a preferred material is 1,2-ditallow oxy-3-trimethyl ammoniumpropane chloride.
  • compositions have a high active level, e.g. which comprise more than 8% of the ester linked quaternary ammonium compound.
  • the extender material (ii) can be selected from mono-long alkyl or alkenyl tertiary or quaternary ammonium compounds and predominantly linear nonionic materials or mixtures thereof.
  • predominantly linear nonionic material refers to materials having a molecular backbone whereto no- or only a small number of side groups are attached.
  • the molecular backbone constitutes more than 75% by weight of the molecule, more preferred more than 90%.
  • the extender materials for use in a composition of the invention it is preferred only the use materials which are of acceptable biodegradability.
  • Especially useful extender materials are:
  • the level of extender material is more than 0.2%, especially preferred are systems comprising more than 0.5% of extender material.
  • the level of extender material will usually not exceed 50% by weight of the composition, more preferred the level is less than 30%, typically from 0.5 to 10% by weight of the composition.
  • the weight ratio of ester-linked quaternary ammonium materials (i) to extender materials (ii) is preferably from 20:1 to 1:10, more preferred from 10:1 to 1:2, especially preferred from 9:1 to 1:1.
  • compositions of the invention are obtainable by heating a mixture of the materials (i) and (ii) to a temperature of above 40°C followed by dispersing the mix into water.
  • the materials are heated to a temperature of above 50°C and dispersed in water of elevated temperature.
  • Compositions made by this method show a surprising good stability and no or only a small viscosity increase upon storage. It is believed that this increased stability may be caused by the particularly good homogeneity of the products obtained by using this method.
  • particular preferred products in accordance with the present invention comprise the above mentioned two materials (i) and (ii) dispersed in water, wherein the mean particle diameter of the dispersed softener phase is less than 10 ⁇ m, preferably less than 7 ⁇ m, especially preferred less than 3 ⁇ m.
  • Such small particle dispersion are often referred to as microdispersions.
  • compositions of the invention preferably have a pH of more than 2.0.
  • pH of the composition is less than 8.0, more preferably less than 5.0.
  • pH values in the range of from 2.5 to 4.0.
  • 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 compounds, preferably the compositions of the invention are substantially free of these quaternary ammonium compounds.
  • Softening materials which may be incorporated in a composition of the invention are amines, such as for instance described in EP 89200113.2, or biodegradable amphoteric softener materials such as for instance described in EP 89200113.2.
  • the amount of active materials other than the above mentioned ester-linked materials and extender 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 preferred less than 1:1, most preferred less than 0.5:1.
  • the composition can also contain one or more optional ingredients selected from non-aqueous solvents such as C 1 -C 4 alkanols and polyhydric alcohols, pH buffering agents such as strong or weak acid e.g. HCl, H 2 SO 4 phosphoric, benzoic or citric acids, rewetting agents, viscosity modifiers such as electrolutes, for example calcium chloride, antigelling agents, perfumes, perfume carriers, fluorescers, colourants, hydrotropes, antifoaming agents, antiredeposition agents, enzymes, optical brightening agents, opacifiers, stabilisers 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 of 2-bro
  • These optional ingredients if added, preferably are present at levels up to 5% by weight of the composition.
  • a preferred method to prepare compositions according to the invention is to form a molten mixture of the ester-linked quaternary ammonium materials (i) and the extender materials (ii) eventually in combination with other softening materials and/or other optional ingredients, and adding this premix to water under 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 compounds (i) and the extender compound in this liquor will be between about 30ppm and 1000ppm.
  • the weight ratio of the fabrics to liquor will generally be between 1:1 and 1:20.
  • compositions were prepared by heating the active ingredients to a temperature of 60°C and dispersing the premelt into water of 60°C under stirring.
  • the resulting compositions according to the invention were homogeneous dispersions, wherein the mean diameter of the dispersed active particles was less than 1 ⁇ m.
  • compositions of the present invention A-C
  • biodegradable softener actives D
  • compositions were prepared as in example 1.
