- ~` FABRIC TREATMENT COMPOSITION
Technical Field The present invention relates to fabxic treatment compositions. In particular it relates to fabric treatme~t compositions comprising 50~tening clays and softsning polysiloxanés and floccula~ing agents.
, . . " . ~
Backuround_of the_Inven~ion -- The use of ~oftening clays in ~abric trea~ment compositions is well known in the art and has found wide commercial application. Clays have been us~d in particular because their application and the so~tening they i~par~ on fabrics is different ~rom that of cationic soEteners, Examples and description of clay appli~ation~ can be found in a large number o~ publicati4ns, fQr example U.S.
3,966,629 or U.~. 1,400,89~ describe different ~inds o~
clays and modes of application of ~hem in fabric treatment compositions.
,, W0 92t07927 PCT/IJS91~(379l9 Co~binatioll o~F clay with so:etening am~ne:; ha5 also b2en disc:lo~;ed to provide so~tening enhance~t. Further DE-3 833 648 dess~ proved aggl~meration o~ tergQnts conta~ soft~ing clay. Further a huD~ctant is p:rovicl~l ~n EP-~ 313 146 facilitating impro~red wetalbility o~ t:he slay.
Other agents which have been known for fabric treatment benefit:s are substituted polysiloxanes. They are disclosed for use at law levels for example in E~A-150 867 or EP-~-150 872. Relatively high concentrations of substitu~ polysiloxanes are not uncommon to the textile ~ndustry and have been disc:losed :~or example ir EP-A~58 ~93 or U.S. 4,247,592.
In EP A-354 856 the comb:Lnation of siloxanes and cationi :: quaternary almnonium is disclosed.
EP-A-381 487 disc:loses liquid dete2~ent compositions corltaining a clay component which is pretreated with siloxane to supply phase ar~d viscosi~r stability while not deteriora~:ing the cle~ing performance.
It has now been found that the fabric treatment performance of substikuted polysiloxanes, soft~.ing c:lay and a clay flocculating agent is substantially hi~7her than was to be e:~pected by simple adltlitiYe perfor~mce.
Part~cularly when praviding ~ntimate mixh~es of soft2lling clay ~d substikuted ps:~lysiloxanes in ~e presence o~ clay flocculating agents the so~t~irlg ~rfonnance ris2s beyond the expectable acldlitive softening perfonnance of the com~ounds pro~ided.
., .~W092/07927 P~T/~X~ 7919 2~9 52~-It is an objective of the in~ention to provide fabric treatment co~positions containing substituted polysiloxanes, so~tening clay and a clay floc~ul~ting agent, pr~ferably as an intimate mix*ure. Further it is an objective to provide softening-through~the-wash deterg~nt compositions comprising such fabric treat~ent composition~
preferably granular datergent compositions.
It is another aspec~ of ~he invention to have very good environmen~al compatibility o~ ~he softening composition in all modes of application or use.
Summary__~ the Inventlon The present inven~ion rela~es to fabric treatment compositions cQmprising a sof~ening clay, a clay flocculating agent, and a subs~ituted polysiloxaneO The substituted polysiloxane is present in said composltions at 0.1% to 50% of said softening clay and the clay flocculaking agent is presen~ at 0.005% to 20% of said softening clay.
The fabric treatment composition can be applied in liguid or granular products and used as such in th~ w~sh or in the rin~e cycle of the laundry. In a pre~erred t embodi~ent of the present invention said fa.bric treatmant compositions are co~prised in softening through-the-~ash (STW~ detergent compositions~ According to the in~ention STW detergent ompositions contain at least one surfactant and ~rom 1% to 50~, pre~erably ~rom l-~ to 20%, mor~

The clay floçcu~ a~LA~ent Clay flo ~ ating agents are not commonly used in fabric treat~e~t compositions~ on the contrary, one is inclined to usz clay dispersants, which aid in removing clay stains fro~ fabrics. Clay flocculating agents are, however, vexy well Xnown in othPr industr.ies like oil well drilling, and for ore flotation in metallurgy. Most of th~se materials ~re fairly long chain polymers and copolymers derived from such monomers as ethylene oxide, acrylamide, acrylic acid, dime~hylam mo e~hyl me~hacrylate, vinyl alcohol, vinyl pyrrolidone, ethylene imine. 5ums, like guar gum, are suitable as well.
Preferred are polymers of ethylene oxida, acryl amide~
or acrylic acid. It has been found that ~hese polymers dramatically enhance the deposition o~ a d ay if their molecular weights (weight average) are in the range of from lOO,OOO^to 10 million. Preferred are -~uch polymers having a (weight average) ~olecular weight of from 150.000 to 5 million, more preferably ~rom 150,000 to 800,000.
The most preferred polymer is poly-(e~hylene-oxide).

If provided a~ an aqueous dispersion, the fabric treatment composition preferably further compri~es an antisettling agent~ ~ccording to the invention, the aqueous di~persion com~rises clay of thP fabric treatment composition ~ro~ 005~ to 30% of the aqueous di~persion and siloxane and clay ~locculating agent in according amountsO
., A suitable antisettling ag~nt must provide a fully activated suppor~ matrix ~o suspend par~ioles ~ithin ~he liquid compositionsO
WO 92/07927 ~ P~ 7gl9 2 ~ r;
Particles in this sense are granul~s or droplets of suspendable size for the desired properties of the liquid composition. Usually said particle size will be less th~n 200 micr~meters. The individual par~icles can c~mpris2 one or more of the essential or optional c~mpounds o~ the fabric treatment compositions.
Finally, an acceptable antisettling agent must not adversely effect the viscosi~y, elas~icity or aes~hetics of the product~
These antise~tling agents, or mixtures thereo~, are used in the compositions of the present invention at le~els of from 0.25% to 5%.
Organophillic quaternized ammonium-clay compounds for example of the Bentone R family of clays ~nd also f~uned silicas are examples of an~ise~tling agen~s suita~le for use in ~he present invention. Bentone R rheological additi~es axe described as the products of a clay which contains a negative layer-la~ice and an organic compound which con~ains a cation and at least one alkyl group containing at leas~ 10 car~on atoms. Bentones R have ~he propert~ of swelling in certain organic liquids.
Organophillic: quaternized alm~onium-clay cor[~ounds are preferred antisettling agents as described in UOS. pat~nt 4,287,08~.
Fumed 5ilicas also provide excellent antisettling characteristics to the compositions of ~he present invention~ Fumed silicas are generally defined as a colloidal fonm of silica made by combustion o:~ silicon tetrachloride in a hydroyen oxygen ~urnace. F~ed silicas are normally used as ~hickener, thixotrop.lc and reinEoxcing W092/07~27 ', ; ~CrlUS91l~7 agents in inks, resins, rubber, paints and cosmetics.
O-SIL~ ~umed silica~ are sui~abl~ antlsettling agent~
for use in th~s invent1on~
.. . . , ~
Other antisettling agents are cellulosic ~uspending agents. For example carboxy-alkyl~celluloses, pre~erably carboxy-methyl-cellulose, are excellent suspending ag~nts.
Furthermore other suspending agents known in the art can be applied.
Mixtures of Bentone R clays, fumed silicas or cellulosic suspending agents are also suitable antisettling agents.
The rheological characteristics o~ the resulting liquld compositions are very importa~t to 2 co~mercially acoeptable product. A liquid which oan be described as stringy ( i . e ., elastie), ~hick or lumpy is undesirable.
The antisettling agents described above avoid these unde~irable rheological properties while maintaining a pourable, homogeneous produc~ with good consumex appeal~ A
viscosity in the range of ~rom about 100 to about 1000 kg/(ms) is desirable.
It is also desirable ~or th liquid oompo~ition to exhibit plastic rheology. Materials th~t exhi~it plastic flow characteristics will flow only ~t~r an ~pplied shearing stress e~ceeds a critical minimum val ue .

Technical Field The present invention relates to fabxic treatment compositions. In particular it relates to fabric treatme~t compositions comprising 50~tening clays and softsning polysiloxanés and floccula~ing agents.
, . . " . ~
Backuround_of the_Inven~ion -- The use of ~oftening clays in ~abric trea~ment compositions is well known in the art and has found wide commercial application. Clays have been us~d in particular because their application and the so~tening they i~par~ on fabrics is different ~rom that of cationic soEteners, Examples and description of clay appli~ation~ can be found in a large number o~ publicati4ns, fQr example U.S.

Other agents which have been known for fabric treatment benefit:s are substituted polysiloxanes. They are disclosed for use at law levels for example in E~A-150 867 or EP-~-150 872. Relatively high concentrations of substitu~ polysiloxanes are not uncommon to the textile ~ndustry and have been disc:losed :~or example ir EP-A~58 ~93 or U.S. 4,247,592.
In EP A-354 856 the comb:Lnation of siloxanes and cationi :: quaternary almnonium is disclosed.
EP-A-381 487 disc:loses liquid dete2~ent compositions corltaining a clay component which is pretreated with siloxane to supply phase ar~d viscosi~r stability while not deteriora~:ing the cle~ing performance.
It has now been found that the fabric treatment performance of substikuted polysiloxanes, soft~.ing c:lay and a clay flocculating agent is substantially hi~7her than was to be e:~pected by simple adltlitiYe perfor~mce.
Part~cularly when praviding ~ntimate mixh~es of soft2lling clay ~d substikuted ps:~lysiloxanes in ~e presence o~ clay flocculating agents the so~t~irlg ~rfonnance ris2s beyond the expectable acldlitive softening perfonnance of the com~ounds pro~ided.

The clay floçcu~ a~LA~ent Clay flo ~ ating agents are not commonly used in fabric treat~e~t compositions~ on the contrary, one is inclined to usz clay dispersants, which aid in removing clay stains fro~ fabrics. Clay flocculating agents are, however, vexy well Xnown in othPr industr.ies like oil well drilling, and for ore flotation in metallurgy. Most of th~se materials ~re fairly long chain polymers and copolymers derived from such monomers as ethylene oxide, acrylamide, acrylic acid, dime~hylam mo e~hyl me~hacrylate, vinyl alcohol, vinyl pyrrolidone, ethylene imine. 5ums, like guar gum, are suitable as well.

WO 92/07927 ~ P~ 7gl9 2 ~ r;
Particles in this sense are granul~s or droplets of suspendable size for the desired properties of the liquid composition. Usually said particle size will be less th~n 200 micr~meters. The individual par~icles can c~mpris2 one or more of the essential or optional c~mpounds o~ the fabric treatment compositions.
Finally, an acceptable antisettling agent must not adversely effect the viscosi~y, elas~icity or aes~hetics of the product~
These antise~tling agents, or mixtures thereo~, are used in the compositions of the present invention at le~els of from 0.25% to 5%.
Organophillic quaternized ammonium-clay compounds for example of the Bentone R family of clays ~nd also f~uned silicas are examples of an~ise~tling agen~s suita~le for use in ~he present invention. Bentone R rheological additi~es axe described as the products of a clay which contains a negative layer-la~ice and an organic compound which con~ains a cation and at least one alkyl group containing at leas~ 10 car~on atoms. Bentones R have ~he propert~ of swelling in certain organic liquids.
Organophillic: quaternized alm~onium-clay cor[~ounds are preferred antisettling agents as described in UOS. pat~nt 4,287,08~.
Fumed 5ilicas also provide excellent antisettling characteristics to the compositions of ~he present invention~ Fumed silicas are generally defined as a colloidal fonm of silica made by combustion o:~ silicon tetrachloride in a hydroyen oxygen ~urnace. F~ed silicas are normally used as ~hickener, thixotrop.lc and reinEoxcing W092/07~27 ', ; ~CrlUS91l~7 agents in inks, resins, rubber, paints and cosmetics.
O-SIL~ ~umed silica~ are sui~abl~ antlsettling agent~
for use in th~s invent1on~
.. . . , ~
Other antisettling agents are cellulosic ~uspending agents. For example carboxy-alkyl~celluloses, pre~erably carboxy-methyl-cellulose, are excellent suspending ag~nts.
Furthermore other suspending agents known in the art can be applied.
Mixtures of Bentone R clays, fumed silicas or cellulosic suspending agents are also suitable antisettling agents.
The rheological characteristics o~ the resulting liquld compositions are very importa~t to 2 co~mercially acoeptable product. A liquid which oan be described as stringy ( i . e ., elastie), ~hick or lumpy is undesirable.
The antisettling agents described above avoid these unde~irable rheological properties while maintaining a pourable, homogeneous produc~ with good consumex appeal~ A
viscosity in the range of ~rom about 100 to about 1000 kg/(ms) is desirable.
It is also desirable ~or th liquid oompo~ition to exhibit plastic rheology. Materials th~t exhi~it plastic flow characteristics will flow only ~t~r an ~pplied shearing stress e~ceeds a critical minimum val ue .
