Definitions

  • the present invention relates to a fabric conditioning composition, in particular the invention relates to aqueous dispersions of fabric conditioning compositions comprising a water insoluble quaternary ammonium material and a zwitterionic compound suitable for a rinse-added fabric softener compositions.
  • Rinse added fabric conditioning composition are known.
  • Such compositions contain a water insoluble quaternary ammonium fabric softening agent dispersed in water at a level of softening agent up to about 7 wt%, in which case the compositions are considered dilute, or at levels from 7 wt% to 50 wt%, in which case the compositions are known as concentrates.
  • a further problem that arises in colder climates is when a fabric conditioner is transported or stored in a cold place the product gels to form a solid. In some cases the product does not recover and in others the time taken to thaw back to a liquid product frequently takes a couple of days. This poses a problem to supermarkets whom can not place the frozen product directly onto supermarket shelves.
  • EP 280 550 and EP 507 478 disclose the use of selected nonionic stabilising agents to overcome the poor stability. However no mention is made of the instability of the formulation when perfume is added.
  • US 3 984 335 discloses compositions containing a quaternised fatty amine and a fatty acid zwitterionic compound as a softening agent.
  • Zwitterionic softening agents such as amine oxides are disclosed in EP 0 332 270 (Unilever) in combination with cationic softening agents and an amine.
  • EP 0 326 213 discloses a fabric treatment composition
  • a fabric treatment composition comprising one or more water-soluble amphoteric fabric conditioning materials, preferably an amine oxide and a coactive material, the weight ratio of the amphoteric material to co-active being from 5:1 to 50:1.
  • the co-active may be a cationic, nonionic or semi-polar surfactant.
  • the present invention aids recovery of a liquid fabric conditioner from a frozen state to a homogeneous liquid.
  • the present invention claims a fabric conditioning composition comprising greater than 7 wt% of a biodegradable quaternary ammonium with at least one ester link, fabric softening agent, characterised in that the composition further comprises from 0.1 to 8 wt% of a zwitterionic compound of the formula: wherein R is an C 7 - 27 alkyl or alkenyl group; R 1 and R 2 are independently selected from C 1-4 alkyl groups; a is an integer from 0 to 1; b and c are independently selected from integers from 1 to 4; Z is oxygen or nitrogen and X is a compatible anion.
  • the anion may be protonated.
  • the invention also discloses the use of an alkyl amido propyl dimethyl amino acetic acid betaine of the formula: wherein R is a C 11-17 alkyl chain or mixtures thereof, to stabilise a perfumed fabric conditioner or to form a concentrated fabric conditioner.
  • the cationic active used in the present invention comprises a water insoluble cationic fabric softening agent comprising a biodegradable quaternary ammonium material with at least one ester link.
  • Preferred materials are water insoluble cationic fabric softening agents comprising a compound having two C12-28 alkyl or alkenyl groups connected to a quaternary nitrogen via an ester link.
  • softening compounds having the formula: in which R 1 is a C 1 -C 4 alkyl groups, R 2 and R 3 are the same or different C 12 -C 22 alkyl or alkenyl groups and T is the same or different. groups and X - is a water soluble anion.
  • the quaternary ammonium material is of the formula wherein R 1 , R 2 and R 3 are each an alkyl or hydroxyalkyl group containing from 1 to 4 carbon atoms, or an alkenyl with 2 to 4 carbon atoms, or a benzyl group, R 4 and R 5 are each alkyl chains containing from 8 to 28 carbon atoms and X - is a water soluble anion.
  • water insoluble cationic active is N,N-dihardened(tallowoyl-oxy) N,N-trimethyl ammoniopropane chloride
  • the level of ester linked ammonium compound is above 7 % by weight of the composition; more preferably above 15% by weight of the composition; most preferably from 15% to 40% by weight of the composition.
  • the zwitterionic material used in the present invention is an alkyl amido propyl dimethyl amino acetic acid betaine of the formula: wherein R is a C 11-17 alkyl chain or mixtures thereof.
  • the level of zwitterionic material is preferably from 0.1 wt% to 8 wt% of the composition; more preferably from 0.4 wt% to 5 wt% of the total composition.
  • the fabric conditioning composition may be formed from any base but it is especially preferred if the base is aqueous.
  • the composition may also contain long chain fatty acid material for example C 8 - C 24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
  • long chain fatty acid material for example C 8 - C 24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
  • saturated fatty acids are used, in particular hardened tallow C 16 - C 18 fatty acids.

  • ethoxylated fatty alcohols are present in the composition. It is especially advantageous if they are present from 0.5 wt% to 2 wt% of the total composition.
  • the perfume may be encapsulated or free.
  • the level of perfume in the product is preferably above 0.1 wt%, more preferably between 0.5wt% and 3.0 wt%.
  • composition may also contain nonionic fabric softening agents such as lanolin and derivatives thereof.
  • the viscosities of these fabric compositions lie in the range from 15 mPa.s to 120 mPa.s at a shear rate of 110s -1 .
  • compositions of the invention preferably have a pH of more than 2, more preferably between 2 and 5.
  • Liquid fabric softening agents were made up as follows:
  • the cationic fabric softening agent and nonionic stabilising agent 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 ambient temperature with constant stirring to form a dispersion.
  • Perfume was added to the aqueous mixture. Addition of the zwitterionic material occurred either
  • HT TMAPC is 1,2 dihardened tallowyloxy trimethyl ammoniopropane chloride ex Hoescht.
  • Tego betaine L is Alkyl amido propyl dimethyl amino acetic acid betaine ex Shell.
  • Example 7 and Example G flocculated on addition of perfume. However Example 7 needed twice as much perfume to flocculate as Example G.
