Definitions

  • the present invention relates to fabric softeners.
  • the compositions according to the invention are concentrated aqueous fabric softening compositions which retain viscosity upon dilution.
  • Concentrated aqueous fabric softening compositions have been extensively described in the art, and one aspect which has often been discussed is the viscosity of these concentrated compositions; indeed these concentrated compositions are typically extremely viscous and the prior art has often described means by which the viscosity of these concentrated compositions could be controlled or decreased.
  • One aspect which has been much less dealt with is the viscosity of these concentrated compositions upon dilution; indeed it has been observed that the viscosity of such concentrated compositions dramatically drops upon dilution, and this viscosity loss is clearly undesirable, essentially in terms of consumer acceptance.
  • Concentrated aqueous fabric softeners have been described for instance in EP 56 695, EP 13 780, DE 26 31 114 and EP 60 003, and a process for the preparation of concentrated fabric softening compositions is disclosed in EP-A-316 996.
  • EP 0,309,052 discloses concentrated aqueous fabric softening compositions comprising a fabric softener component and a linear fatty ethoxylated alcohol.
  • a concentrated aqueous fabric softening composition comprising from 10% to 35% by weight of a cationic fabric softening active or mixtures thereof, said composition further comprising:
  • the present invention also encompasses a method for the softening of fabrics, wherein the above concentrated compositions are diluted in water before they are contacted with said fabrics in the rinse water.
  • compositions according to the invention are concentrated fabric softeners; by concentrated, it is meant that the compositions comprise from 10% to 35% by weight of the total composition of a cationic fabric softening active or mixtures thereof, preferably 15% to 25%.
  • cationic it is meant any softening compound which is in cationic form in the concentrated softening composition.
  • Suitable cationic fabric softening actives include
  • Component (i) are the well-known dialkyldimethylammonium salts such as ditallowdimethylammonium chloride (DTDMAC), ditallowdimethylammonium methylsulfate, di(hydrogenated tallow) dimethylammonium chloride, dibehenyldimethylammonium chloride.
  • DTDMAC ditallowdimethylammonium chloride
  • ditallowdimethylammonium methylsulfate di(hydrogenated tallow) dimethylammonium chloride
  • dibehenyldimethylammonium chloride ditallowdimethylammonium chloride

  • Component (iv) are l-methyl-1-tallowamido-ethyl-2-tallowimidazolinium methylsulfate and 1-methyl-1-(hydrogenated tallowamidoethyl)-methylsulfate.
  • Suitable fabric softening actives include the following amines, provided they are present in the concentrated softening composition in a protonated form; such amines are of the formula : wherein n is 2 or 3, preferably 2; R 1 and R 2 are, independently, a C 8 -C 30 alkyl or alkenyl, preferably C 12 -C 20 alkyl, more preferably C 15 -C 18 alkyl, or mixtures of such alkyl radicals. Examples of such mixtures are the alkyl radicals obtained from coconut oil, "soft" (non-hardened) tallow, and hardened tallow.
  • Q is CH 2 or N, preferably N
  • X is wherein T is O or NR 5 , R 5 being H or C 1 -C 4 alkyl, preferably H, and R 4 is a divalent C 1 -C 3 alkylene group or (C 2 H 4 O)m, wherein m is an integer of from 1 to 8; or X is R 4 .
  • Most preferred softening agents according to the above formula are imidazolines of the following formula : wherein R1 is a tallow group.
  • the softening amines described herein above are suitable for the purpose of the present invention provided they are present in the concentrated softening composition in a protonated form; a suitable means to protonate these amines is described for instance in EP 199 383.
  • a preferred softening active mixture for use herein is a mixture of 20% to 70% by weight of the softening active of ditallow dimethyl ammonium chloride (DTDMAC) and 30% to 80% ditallow imidazoline.

Description

Technical field
The present invention relates to fabric softeners. The compositions according to the invention are concentrated aqueous fabric softening compositions which retain viscosity upon dilution.
Background
Concentrated aqueous fabric softening compositions have been extensively described in the art, and one aspect which has often been discussed is the viscosity of these concentrated compositions; indeed these concentrated compositions are typically extremely viscous and the prior art has often described means by which the viscosity of these concentrated compositions could be controlled or decreased. One aspect which has been much less dealt with is the viscosity of these concentrated compositions upon dilution; indeed it has been observed that the viscosity of such concentrated compositions dramatically drops upon dilution, and this viscosity loss is clearly undesirable, essentially in terms of consumer acceptance.
It is therefore an object of the present invention to provide a concentrated aqueous fabric softening composition which has an acceptable viscosity in the concentrated form, and which retains acceptable viscosity after it has been diluted.
This technical problem was discussed in GB 2 007 734 which proposes to use a combination of a fatty quaternary ammonium salt having two long chain alkyl groups together with an oily substance.
Concentrated aqueous fabric softeners have been described for instance in EP 56 695, EP 13 780, DE 26 31 114 and EP 60 003, and a process for the preparation of concentrated fabric softening compositions is disclosed in EP-A-316 996.
EP 0,309,052 discloses concentrated aqueous fabric softening compositions comprising a fabric softener component and a linear fatty ethoxylated alcohol.
Summary of the invention
It has now been found that the above object can be achieved by formulating a concentrated aqueous fabric softening composition comprising from 10% to 35% by weight of a cationic fabric softening active or mixtures thereof, said composition further comprising:
  • from 0.3% to 3 % by weight of the total composition of a linear fatty alcohol ethoxylate of the formula RO(Etox)n, wherein R is a linear C8-C18 alkyl chain, and n representing the weighted average ethoxylation degree is of from 3 to 35, or mixtures thereof;
  • From 0.5% to 6% by weight of the total composition of a nonionic hydrophilic polymer, or mixtures thereof;
  • from 0% to 2% by weight of the total composition of a highly branched fatty alcohol having from 8 to 18 carbon atoms, or mixtures thereof;
  • from 0% to 0.5 % by weight of the total composition of a linear or cyclic polydialkylsiloxane of the formula
    Figure 00030001
    wherein R is a C1-C5 alkyl chain, and m is an integer of from 1 to 500, or mixtures thereof.

    Figure 00060003
    wherein R1 is a tallow group.
    The softening amines described herein above are suitable for the purpose of the present invention provided they are present in the concentrated softening composition in a protonated form; a suitable means to protonate these amines is described for instance in EP 199 383.
    A preferred softening active mixture for use herein is a mixture of 20% to 70% by weight of the softening active of ditallow dimethyl ammonium chloride (DTDMAC) and 30% to 80% ditallow imidazoline. Preferably, the concentrated compositions according to the invention comprise from 15% to 25% by weight of the finished product of such a mixture.
    In an alternative preferred embodiment of the present invention, the softening active comprises a ditallow imidazoline ester such as described herein above (i.e. when T is O and R1 and R2 are both tallow in the formula above). This embodiment is particularly preferred for environmental reasons.
    The compositions according to the invention further comprise from 0.3% to 3% by weight of the total composition of a linear fatty alcohol ethoxylate of the formula RO(Etox)n, wherein R is a linear C8-18 alkyl chain, and n representing the weighted average ethoxylation degree is of from 3 to 35, or mixtures thereof. Preferred are linear fatty alcohol ethoxylates wherein R is a linear chain having from 10 to 13 carbon atoms, and wherein n is from 5 to 10, preferably 8. Preferably, these compounds, or mixtures thereof are present at levels of from about 1 to about 1.5% by weight of the total composition. These compounds are commercially available from BASF under the trade name LUTENSOL TO®.
    The compositions according to the present invention further comprise from 0.5% to 6% , preferably from 1.5% to 2.5% by weight of the composition of a nonionic hydrophylic polymer, or mixtures thereof. Such suitable polymers include polyethylene glycol, polypropylene glycol, polyvinylalcolhol and the like. Particularly preferred is a polyethylene glycol having a molecular weight of from 300 to 50000, preferably 2000 to 10000. In the preferred embodiment herein where the softening active is a mixture of DTDMAC and ditallow imidazoline, it is preferred to use a polyethylene glycol with a molecular weight of about 4000. In the alternative preferred embodiment where the softening active comprises ditallow imidazoline ester, it is preferred to use a polyethylene glycol with a molecular weight of about 8000.
    The compositions according to the present invention further comprise from 0% to 2%, preferably from 0% to 0.1% by weight of the total composition of a highly branched fatty alcohol having from 8 to 18 carbon atoms, preferably 12 to 14, or mixtures thereof, most preferably 13. Branched compounds similar to said highly branched fatty alcohols are often present in perfumes; thus, the level of said highly branched fatty alcohol to be added to the composition must be adjusted depending on the perfume which is used, if any. Such highly branched fatty alcohols suitable for use in the compositions according to the present invention are commercially available from EXXON under the trade name EXXAL®.
    The compositions according to the invention may further comprise from 0% to 0.5% by weight of the total composition of a linear or cyclic polydialkylsiloxane of the formula:
    Figure 00080001
    where R is a C1-C5 alkyl group and m is an integer of 1 to 500, or mixtures thereof. Said polydialkylsiloxanes components are not essential ingredients in the compositions according to the invention, as the compositions will retain viscosity upon dilution even in the abscence of such polydialkylsiloxanes. However, several benefits can be obtained from these polydialkylsiloxanes, including improved stability of the finished product, improved water absorbancy of the treated fabrics. Said polydialkylsiloxanes can also be helpful in avoiding the formation of fabric softener residues which may occur in the dispenser of the washing machine. Thus, preferred compositions according to the present invention comprise from 0.05% to 0.5%, most preferably from 0.1% to 0.3% by weight of the total composition of the above polydialkylsiloxanes, or mixtures thereof. In the compositions according to the present invention where the softening active comprises the ditallow imidazoline ester described herein above, it is preferred to use a polydialkylsiloxane where R is methyl and m is about 200. In other compositions, it is preferred to use a polydialkylsiloxane where R is methyl and m is 7. Suitable polydialkylsiloxanes are commercially available from DOW CORNING under the trade name 200 fluid, and the preferred polydialkylsiloxanes for use herein are DOW CORNING's 200 fluid 350 CS (R is methyl and m is 203) and 5 CS (R is methyl and m is 7).
    The compositions according to the invention may additionally comprise such conventional ingredients as perfumes, preservatives, germicides, colorants, fungicides, stabilizers, brighteners, opacifiers and the like, at conventional levels, i.e. up to about 5% by weight of the composition.
    The compositions in their concentrated form have a viscosity of from 40 to 400 mPa.s (cps) at 60 RPM shear rate. The compositions according to the invention can be used directly in the concentrated form, or they can preferably be diluted before they are used. The compositions according to the present invention are meant to be diluted in water, preferably in 2 to 3 times their weight of water. In diluted form, the compositions have a viscosity of from 20 to 60 mPa.s (cps) at 60 RPM shear rate, preferably 30 to 50 mPa.s (cps) at 6o RPM shear rate.
    Thus, the present invention also encompasses a method for the softening of fabrics wherein the concentrated fabric softening compositions described herein above are diluted in water before they are contacted with said fabrics. In a preferred embodiment of said method, a concentrated softening composition as described hereinabove, which has a viscosity of from 40 to 400 mPa.s (cps) at 60 RPM shear rate, is diluted in two times its weight of water so as to obtain a diluted fabric softening composition having a viscosity of from 20 to 60, preferably 30 to 50 mPa.s (cps) at 60 RPM shear rate, and said diluted fabric softening composition is contacted with said fabrics in the rinse water.
