Definitions

  • This invention relates to fabric softening compositions and, in particular, to compositions in aqueous medium having improved softening effectiveness combined with excellent physical characteristics, especially formulation stability.
  • Conventional rinse-added fabric softening compositions contain fabric softening agents which are substantially water-insoluble cationic materials usually having two long alkyl chains. Typical of such materials are distearyl di-methyl ammonium chloride and imidazolinium compounds substituted with two stearyl groups. These materials are normally prepared in the form of an aqueous dispersion or emulsion, and it is generally not possible to prepare such aqueous dispersions with more than about 6% of cationic material without taking special precautions to ensure acceptable viscosity and stability characteristics. Indeed, with cationic levels in excess of about 8% the problems of physical instability and high viscosity become, in the case of conventional fabric softening products, almost intractable. This, of course, limits the level of softening performance achievable with conventional compositions without using excessive amounts of product, and also adds substantially to distribution and packaging costs, because of the need to market such dilute solutions of the active ingredient.
  • Formulations prepared in this manner are still not entirely satisfactory.
  • the level of softness benefit delivered by such compositions on a unit active weight basis is still much lower than for conventional dilute products and problems of physical formulation characteristics, especially phase stability and also viscosity, still remain.
  • an important limitation of the prior art compositions is the difficulty in meeting simultaneous product stability and viscosity characteristics. Indeed, phase stability remains a problem even in the case of dilute softener compositions formulated in the manner of the above prior art references.
  • 25 03 026 discloses a complex softener/disinfec- tant composition in which a long chain fatty alcohol is suggested as a solubilization aid.
  • U.S. Patent No. 3,793,196 describes an improved viscosity softening agent in the form of an oil-in- water emulsion comprising a cationic surface-active agent, a higher fatty alcohol, a sorbitan fatty acid ester and a polyethoxylated nonionic surfactant.
  • the present invention accordingly provides a fabric softening composition having improved softening characteristics and cost-effectiveness combined with excellent physical characteristics, especially phase stability, freeze-thaw behaviour and low viscosity; and it further provides a concentrated fabric softening composition having satisfactory characteristics for consumer use, based on cationic fabric softener as the major active component.
  • an aqueous fabric softening composition characterized by:-
  • the physical form of the composition is that of a dispersion of an anisotropic softener phase in an aqueous isotropic surfactant solution phase.
  • the physical form is simply determined under a polarizing microscope.
  • the anisotropic/isotropic phase system is highly important for achieving optimum viscosity, stability, softening and other textile benefits.
  • the water insoluble cationic fabric softener is preferably a di-C 12 ⁇ C 24 alkyl or alkenyl 'onion salt, especially a mono- or polyammonium salt, an imidazolinium salt or a mixture of such salts. Highly preferred are mono-quaternary ammonium salts, imidazolinium salts and mixtures thereof.
  • the water-soluble cationic surfactant is preferably a mono-C 8 _ 24 alkyl or alkenyl 'onium salt, especially a mono- or polyammonium salt, an imidazolinium salt, a pyridinium salt or a mixture of such salts. Highly preferred are mono-quaternary ammonium salts, imidazolinium salts and mixtures thereof.
  • the preferred water-soluble nonionic surfactant has the general formula RO(CH 2 CH 2 O) n H wherein R is a C 8 _ 20 alkyl or alkenyl group, and n is from 2 to 100.
  • the weight ratio of water-insoluble cationic to water-soluble cationic and/or nonionic surfactant falls preferably in the range from 20:1 to 4:1, especially from 15:1 to 6:1.
  • the weight ratio of the cationic softener to the hydrophobic adjunct preferably falls in the range from 8:1 to 2:1.
  • compositions of the invention preferably comprise from 0.1 % to 6% of the water-soluble cationic and/or nonionic surfactant, from 0.5% to 6% of the non-cyclic hydrocarbon and from 0% to 6% of the fatty acid ester.
  • percentage figures given for components in a composition refer to the weight percent of that component in the composition.
  • highly preferred materials are C 12 ⁇ C 24 , especially C 12 ⁇ C 20 paraffins or paraffin mixtures, esters of C 12 ⁇ C 24 fatty acids with monohydric alcohols having from 1 to 8 carbon atoms, and mixtures of these paraffin and fatty acid ester materials in a 3:1 to 1:3 weight ratio.
  • compositions of the invention thus comprise three essential ingredients, a water-insoluble cationic fabric softener, a water-soluble cationic and/or nonionic surfactant and a hydrophobic adjunct selected from C 10 ⁇ C 40 non-cyclic hydrocarbons and fatty acid ester, the water soluble surfactant and the hydrophobic adjunct acting in combination to provide compositions of optimum viscosity and stability.
  • a water-insoluble cationic fabric softener e.g., a water-soluble cationic and/or nonionic surfactant and a hydrophobic adjunct selected from C 10 ⁇ C 40 non-cyclic hydrocarbons and fatty acid ester, the water soluble surfactant and the hydrophobic adjunct acting in combination to provide compositions of optimum viscosity and stability.
  • a hydrophobic adjunct selected from C 10 ⁇ C 40 non-cyclic hydrocarbons and fatty acid ester
  • the water-insoluble cationic fabric softener can be any fabric-substantive cationic compound which, in pure form as a strong acid salt (e.g. chloride), has a solubility in distilled water at pH 2.5 and 20°C of less than 1 g/I, or can be a mixture of such compounds.
  • the soluble fraction of the surfactant is taken to be that material which cannot be separated from water by centrifugal action and which passes a 100 nm Nuclepore filter (Registered Trade Mark).
  • Preferred materials are di-C 12 ⁇ C 24 alkyl or alkenyl 'onium salts, especially mono- and poly-ammonium salts, and imidazolinium salts.
  • the two long chain alkyl or alkenyl groups may be substituted or interrupted by functional groups such as -OH, -0-, CONH-, -COO-, etc.

  • these quaternary softeners include ditallow dimethyl ammonium chloride; ditallow dimethyl ammonium methyl sulfate; dihexadecyl dimethyl ammonium chloride; di(hydrogenated tallow alkyl) dimethyl ammonium chloride; dioctadecyl dimethyl ammonium chloride; dieicosyl dimethyl ammonium chloride; didocosyl dimethyl ammonium chloride di(hydrogenated tallow) dimethyl ammonium methyl sulfate; dihexadecyl diethyl ammonium chloride; di(coconut alkyl) dimethyl ammonium chloride and di(coconut alkyl) dimethyl ammonium methosulfate.

  • imidazolinium materials are 2 - heptadecyl - 3 - methyl - 1 - (2 - stearylamido) - ethyl - 4,5 - dihydroimidazolinium chloride and 2 - lauryl - 3 - hydroxyethyl - 1 - (oleylamido)ethyl - 4,5 - dihydroimidazolinium chloride.
  • the water-insoluble cationic softener is present at a level of at least 2%; below this level, the volume of product required to provide an acceptable level of softness benefit becomes excessively large.
  • softener levels in the range of 2% to 6% there is, of course, generally no difficulty in preparing products of conventional type with the necessary low viscosity and good stability by adding, for instance, a low level of calcium chloride.
  • product stability and viscosity become a problem and the overall aim is to adjust the levels of the softening and surfactant components within the prescribed limits to provide products which are stable to separation in a centrifuge at 3000 r.p.m.
  • cationic softener in the present formulations is determined by practical considerations; thus, above a cationic softener level of 22% the problems of physical stability and product viscosity are such that it is not generally possible to formulate stable pourable emulsions based on water-insoluble cationic softener as the major softening component.
