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 & Gamble) viscosity control agents are added to certain concentrated compositions. The agents may include C10 ⁇ 18 fatty alcohols.
  • EP 280550 More recently in 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 concentrate comprising an ester-linked quaternary ammonium compound to form a viscous gel.
  • the stabiliser is a C12 ⁇ 14 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.
  • compositions containing biodegradable quaternary ammonium compounds may be improved by the use of selected nonionic stabilising agents.
  • a fabric softening composition comprising a water insoluble cationic fabric softening agent and a nonionic stabilising agent wherein the water insoluble cationic fabric softening agent is a quaternary ammonium material which comprises a compound having two C12 ⁇ 18 alkyl or alkenyl groups connected to the quaternary nitrogen atom via an ester link and the nonionic stabilising agent is a predominantly linear C8 to C22 alcohol alkoxylated with 10 or more moles of alkylene oxide, and in that the nonionic stabilising agent has a clear phase at a 1% concentration in water somewhere in the range of 0°C and 45°C and a Krafft point less than 30°C.
  • compositions show improved high temperature stability, in particular stability at 37°C.
  • the nonionic surfactant preferably has a krafft point of less than 10°C, most preferably less than 5°C.
  • Krafft point is a term well known in the art, for example from R J Hunter 'Foundations of Colloid Science', Oxford University Press, Volume 1 1989 page 571.
  • the krafft point of a stabilising material is the temperature below which the solubility of the material is low and no micelles are apparent. At temperatures above the krafft point the solution is clear, at temperatures below it the solution is cloudy.
  • compositions of the invention are liquids comprising an aqueous base.
  • ester-linked quaternary ammonium material for use in the compositions according to the invention can be represented by the formula: wherein each R1 group is independently selected from C1 ⁇ 4 alkyl, alkenyl or hydroxyalkyl groups; and wherein each R2 group is independently selected from C8 ⁇ 28 alkyl or alkenyl groups;
  • a second preferred type of quaternary ammonium material can be represented by the formula: wherein R1, n and R2 are as defined above. T is and n is an integer from 0-5.
  • Preferred materials and their method of preparation are, for example, described in US 4 137 180 (Lever Brothers).
  • Preferably 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 is preferably 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 C8 - C22 primary or secondary predominantly linear alcohols with 10 or more moles of ethylene oxide, preferably 15 to 20 moles of ethylene oxide.
  • the alcohols may be saturated or unsaturated.
  • Genapol T-150, Genapol T-200, Genapol C-200 all ex Hoeschst AG, Lutensol AT18 ex BASF, Genapol C-100 Genapol C-150 & Genapol T-350 ex Hoechst.
  • the nonionic stabiliser has an HLB of between 10 and 20, more preferably 12 and 20.
  • the level of nonionic stabiliser is within the range of 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 C8 - C24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
  • fatty acids for example C8 - C24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
  • saturated fatty acids are used, in particular, hardened tallow C16 ⁇ 18 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 between 2 and 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.
  • 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 to water at 70°C to 80°C over a period of at least one minute, with constant stirring to form a dispersion.
  • the viscosity of the compositions was measured by Haake rotoviscometer following 1 and 3 months storage at ambient temperature or at 37°C.
  • the Krafft point was measured by preparing a 1% solution of the nonionic stabilising agent in distilled water and storing the solution at 5°C for 5 days. The solution was then heated gradually with stirring until the solution became clear. The temperature at which the solution became clear was taken as the Krafft point.
  • compositions comprising ester linked quaternary ammonium compounds counteracts destabilisation at high temperature to give stable concentrated compositions.
