Definitions

  • the present invention relates to fabric softening compositions, in particular the invention relates to aqueous dispersions of biodegradable fabric softening compositions comprising a water insoluble cationic fabric softening agent and a nonionic stabilising agent suitable as rinse-added fabric softener compositions.
  • Rinse added fabric softener compositions are well known. Typically such compositions contain a water insoluble quaternary ammonium fabric softening agent dispersed in water at a level of softening agent up to 7% by weight in which case the compositions are considered dilute, or at levels from 7% to 50% in which case the compositions are considered concentrates.
  • fabric softening compositions desirably have other benefits. One is the ability to confer soil release properties to fabrics, particularly those woven from polyester fibres.
  • viscosity control agents In the past physical stability of rinse added fabric softener compositions has been improved by the addition of viscosity control agents or anti-gelling agents.
  • viscosity control agents For example in EP 13780 (Procter and Gamble) viscosity control agents are added to certain concentrated compositions. The agents may include C10-C18 fatty alcohols.
  • EP 280550 Unilever it has been proposed to improve the physical stability of dilute compositions comprising biodegradable, ester-linked quaternary ammonium compounds and fatty acid by the addition of nonionic surfactants.
  • compositions comprising biodegradable ester-linked quaternary ammonium compounds the problem of physical instability is more acute than with traditional quaternary ammonium compounds.
  • a nonionic emulsifier/stabiliser is added to a concentrate comprising an ester-linked quaternary ammonium compound to form a viscous gel.
  • the stabiliser is a C12 to C14 alcohol ethoxylated with 9 molecules of ethylene oxide. The degree of branching of the alcohol is not, however, mentioned.
  • Certain nonionic stabilising agents not only stabilise concentrated compositions comprising biodegradable quaternary ammonium compounds but are also environmentally friendly, in that they show acceptable biodegradability and are not substantially toxic in aquatic systems.
  • Soil release properties are generally imparted to fabrics by the use of separate soil-release agents, usually a high molecular weight polymer, in a detergent composition or separate treatment.
  • separate soil-release agents usually a high molecular weight polymer
  • a cationic polymeric soil release agent for use in a fabric conditioning composition.
  • a disadvantage of such compositions is that the soil release agent increases the number of components in the formulation, increasing cost and making the product less environmentally acceptable.
  • fabric softening compositions comprising biodegradable ester-linked quaternary ammonium compounds may confer improved soil release properties to fabrics.
  • a fabric softening composition comprising a water insoluble cationic fabric softening agent and a nonionic stabilising agent characterised in that the water insoluble cationic fabric softening agent is a biodegradable quaternary ammonium material with at least one ester link and the nonionic stabilising agent is
  • nonionic stabilising agent is a linear C 8 to C22 alcohol alkoxylated with 10 to 20 moles of alkylene oxide
  • compositions of the invention are liquids comprising an aqueous base.
  • the fabric softening composition comprises a water insoluble cationic which is a compound having two C12 ⁇ 28 alkyl or alkenyl groups connected to the N atom via one or more ester links.
  • a preferred type of ester-linked quaternary ammonium material for use in the compositions according to the invention can be represented by the formula: wherein each R 1 group is independently selected from C1 ⁇ 4 alkyl, alkenyl or hydroxyalkyl groups; and wherein each R 2 group is independently selected from C8 ⁇ 28 alkyl or alkenyl groups; T is or and n is an integer from 0-5.
  • a second preferred type of quaternary ammonium material can be represented by the formula: wherein R 1 , n and R 2 are as defined above.
  • 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-hydroxytrimethyl 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 concentrated compositions which comprise more than 7% of ester-linked quaternary ammonium compound.
  • the level of ester-linked quaternary ammonium compounds preferably is between 1% and 80% by weight, more preferably 3% to 50%, most preferably 8% to 50%.
  • Suitable nonionic stabilisers which can be used include the condensation products of C 8 - C22 primary linear alcohols with 10 to 20 moles of ethylene oxide.
  • linear alcohol means a primary alcohol attached directly to a hydrocarbon backbone structure.
  • An HLB of greater than about 12 gives rise to an acceptable acute aquatic toxicity value of >1mg/1;EC50 48 hours for daphnia and algae and EC50 96 hours for fish.
  • nonionic stabiliser has an HLB of between 10 and 20, more preferably 12 and 20.
  • the level of nonionic stabiliser is within the range from 0.1 to 10% by weight, more preferably from 0.5 to 5% by weight, most preferably from 1 to 4% by weight.
  • the mole ratio of the quaternary ammonium compound to the nonionic stabilising agent is within the range from 40:1 to about 1:1, preferably within the range from 18:1 to about 3:1.
  • the composition can also contain fatty acids for example C 8 - C24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
  • fatty acids for example C 8 - C24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
  • saturated fatty acids are used, in particular, hardened tallow C16-C18 fatty acids.
  • the fatty acid is non-saponified, more preferably the fatty acid is free for example oleic acid, lauric acid or tallow fatty acid.
  • the level of fatty acid material is preferably more than 0.1% by weight, more preferably more than 0.2% by weight. Especially preferred are concentrates comprising from 0.5 to 20% by weight of fatty acid, more preferably 1% to 10% by weight.
  • the weight ratio of quaternary ammonium material to fatty acid material is preferably from 10:1 to 1:10.
  • compositions of the invention preferably have a pH of more than 2.0, more preferably less than 5.
  • the composition can also contain one or more optional ingredients, selected from non-aqueous solvents, pH buffering agents, perfumes, perfume carriers, fluorescers, colourants, hydrotropes, antifoaming agents, antiredeposition agents, enzymes, optical brightening agents, opacifiers, anti-shrinking agents, anti-wrinkle agents, anti-spotting agents, germicides, fungicides, anti-oxidants, anti-corrosion agents, drape imparting agents, antistatic agents and ironing aids.

  • composition may also contain nonionic fabric softening agents such as lanolin and derivatives thereof.
  • Liquid fabric softening compositions were made as follows.
  • the cationic fabric softening agent, fatty acid and nonionic stabilising agent where appropriate were premixed and heated together to form a clear melt.
  • the molten mixture thus formed was added over a period of at least one minute, to water at 70°C to 80°C with constant stirring to form a dispersion.

  • the pieces were then line dried and stained with 100 micro litres of olive oil containing 0.06% sudan red dye.
  • the stain was allowed to spread for a minimum of two days following which the reflectance of the stained piece (R 1 ) was measured using an ICS micromatch.
