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.
  • BE-A 871 431 which relates to water-free liquid fabric softener concentrates incorporating oily materials and to dilute aqueous softener compositions prepared there from.
  • 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.
  • NL-A 6706178 relates to viscosity control in fabric softening compositions with up to 12% of cationic softener, and suggests the use of low molecular weight hydrocarbons for this purpose
  • German patent application No. 2503026 discloses a complex softener/disinfectant composition in which a long chain fatty alcohol is suggested as a solubilization aid.
  • 3 793 196 describes an improved viscosity softening agent in the form of an oil-inwater emulsion comprising a cationic surface-active agent, a higher fatty alcohol, a sobitan 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 comprising:
  • weight ratio of (a) to (b) is in the range from 20:1 to 5:2, and the weight ratio of (a) to (c) is in the range from 8:1 to 2:1.
  • 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 'onium 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 0) 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 falls in the range from 8:1 to 2:1.
  • compositions of the invention preferably comprise up to 6% of the water-soluble cationic and/or nonionic surfactant, up 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 and mixtures thereof with esters of C 12 -C 24 fatty acids with monohydric alcohols having from 1 to 8 carbon atoms in a 3:1 to 1: 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 mixtures thereof with specified fatty acid esters, 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 mixtures thereof with specified fatty acid esters, 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 mixtures thereof with specified fatty acid esters

  • Also suitable herein are the imidazolinium fabric softening components of U.S. Patent No. 4127 489.
  • the water-insoluble cationic softener is present at a level of at least 6%.
  • 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. for 16 hours and which have a viscosity of less than 350 mPas, preferably less than 150 mPas measured in a Brookfield Viscometer, using Spindle No. 2 at 60 r.p.m. and at 21°C.
  • the maximum level of 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.
