This invention relates to liquid detergent compositions containing low levels of selected organo-functional polydi-alkylsiloxanes. In more detail, the compositions herein comprise conventional ingredients inclusive of surface-active agents, liquid carrier and optional ingredients such as detergent builders, enzymes and suds regulants and low levels of organo-functional polydi-short alkylsiloxanes. The latter ingredient unexpectedly provides desirable through-the-wash textile benefits inclusive of softness. The preferred selections embrace amino derivatives. Toe essential selections are further characterized by a degree of substitution in the range from Oily - 0.7.
The through-the-wash textile benefits conferred by the inventive compositions, in addition to softening, are frequently perceived in terms of anti-static, ease-of-ironing and anti-wrinkling benefits. On a conservative basis, it was established that, at least, and contrary to standing prejudice, the essential selection components do not, adversely affect the general textile cleaning suitability of the compositions herein.
The liquid compositions herein can be divided arbitrarily in (mostly Built compositions and in substantially unbolt compositions.
Both kinds of compositions will procure r`' 'I
C.' ~23;24~2 textile handling benefits. Selective preference can originate from the combined use of anionic surface-active agents in combination with the subject selections.
The prior art relative to the textile-treatment utilization broadly of silicones/polydialkylsiloxanes is crowded and diverse.
The like selections have, for example, found widespread commercial application in a detergent suds regulant functionality Silicone polymers have also found widespread application in the textile industry to provide fiber properties inclusive of softness, water proofing and easy ironing. To that effect the silicone polymers are applied (in the textile industry) to the fabrics during manufacture or during make-up of clothing, in the form of relatively concentrated dispersions or solutions either by padding Dry spray-on.
Often, especially for long lasting softness, water proofing treatment or other benefits, mixtures of organofunctional polydialkylsiloxanes are used. The fabrics are subsequently treated with catalysts or heated to cause cross linking or setting of the silicone polymers.
German Patent 27 54 504 and So Patent 4,247,592 disclose a treating agent consisting of a polydimethylsiloxane containing dia~inoalkyl groups for providing softness to natural and synthetic fabrics.
Japanese Patent 79,131,096 pertains to a treating agent consisting of a mixture of polydimethylsiloxane with Regroups and a polydimethylsiloxane with hydroxy end groups, for providing softness to acrylics. The fabrics are spray coated and then heated for curing.
German Patent 20 16 095 uses polydimethylsiloxane containing pendant epoxy groups for providing softness and smoothness to synthetic organic fabrics.

European Patent 058 493 relates to a treating agent mixture of an organ polysiloxane containing diaminoalkyl and polyoxyalkylen~
groups, with an organopolysiloxane containing càrboxylic acid ester groups or with an organopolysiloxane containing epoxy and polyoxyalkylene groups. The mixture is added by spray-on and treated for curing. It is said eon provide softness, anti-wrinkling and long lasting electrostatic prevention benefits.
German Patent application DOS 26.31.419 relates to fabric rinse softening compositions containing a fabric-substantive cat ionic component and a polydimethylsiloxane possibly amino substituted. The mixture is applied as an aqueous dispersion.
The suds regulant utilization of polydimethyls~loxanes in liquid detergent is known from European Patent application 0.028.865. US. Patent 4.075.118 discloses the utilization of emulsified polydimethylsilicones for suds regulant purposes.
The feasibility for using polydimethylsilicones in granular detergents for foam control is known from DOS 23.3~.468.
It is also known that the detergent incorporation of polydimethylsiloxane suds regulants can adversely affect textile cleaning benefits.
It has now been found that specific organo-functional polydialkylsiloxanes, preferably amino substituted species, can advantageously be incorporated in liquid detergents generally to provide remarkable benefits inclusive of through-the-wash softening and further textile handling improvements. The essential means needed to achieve these unexpected properties are explained in more detail hereafter.

DETAILED DESCRIPTION OF THE INVENTION
The invention herein broadly relates to liquid detergent compositions comprising a surface-active agent, a liquid carrier, an organo-functional polydi-alkylsiloxane textile treatment agent, and, if desirable, conventional detergent additives. These variables and other aspects of the invention are explained in more detail hereinafter.
Unless indicated to the contrary, the percent indications stand for "percent by weight".
THE SURFACE-ACTIVE AGENT
A first essential component for use in the compositions of this invention is represented by a surface-active agent selected from the group of anionic, non ionic, amphoteric (ampholytic) and zwitterionic surface-active agents and mixtures thereof. In the context of this invention, the term non ionic surface-active agent is meant to include semi-polar non ionic surfactants.
.. .. . . . . . ..
3'2~2 Examples of suitable non-ionic surfactants are disclosed in ETA 0.028.865 page 4, line 23 to page 5, line 10 and page 8, line 14 to page 9, line 4.
A disclosure of zwitterionic and ampholytic surfactants for use herein can also be found in ETA
0.028.865 page 7, line 21 to page 8, line 13.
The anionic surfactants for use herein can be represented by known synthetic and natural anionic surface-active agents which are known to be suitable for use in detergents and frequently have found commercial application. Suitable synthetic anionic surfactants are described in ETA 0.028.865 page 5, line 12 to line 31.
Examples of natural anionic surface-active agents for use in this invention can be represented by saturated and unsaturated fatty acids having from 10 to 20 carbon atoms in the alkyd chain or the alkali-metal, earth-alkali-metal and amine or alkanolamine soaps thereof. Preferred fatty acids/soaps have from 12 to 18 carbon atoms in the alkyd chain. Well-known examples of fatty acids/soaps suitable for use herein are natural coconut fatty acid containing a majority of C12 and C14 acids and tallow fatty acids containing a mixture of saturated and unsaturated C16 and C18-fatty acids/soaps-The surface-active agent is used generally at levels from 5% to 70%. While the surface-active agent may be varied over the broad range depending upon the intended utility of the composition and the quantitative and qualitative definition of the additional ingredients and possible optional components, two preferred executions can be formulated depending upon the presence of (poly)-phosphate builders.
lL~3~
In a first preferred execution of the invention liquid compositions are envisaged which are substantially unbolt. In this embodiment, the surface active agents are frequently used in an amount from 25% to 55~ and are represented by a mixture of anionic and non ionic surface-active agents, more preferably in a weight ratio of anionic to non ionic in the range from 4:1 to 1:4.
In a second preferred embodiment, liquid built detergent compositions are contemplated containing from I to 25%, preferably from 5% to 15~ surface-active agent. The latter ingredient can preferably be represented by a mixture of anionic and non ionic surface-active agents whereby the anionic species represents at least 20~ of the sum of anionic and non ionic surface-active agents, and at least I calculated on the detergent composition.
The like detergent compositions frequently comprise from 5% to 30%, preferably from 12~ to 25% of a detergent builder which can be represented by conventional detergent builders many of which have already found commercial application. Well-known examples of suitable builders include the alkali, often sodium, metal salts of (poly)phosphates, e.g. tripolyphosphoric acid, nitrilotriacetic acid (NAT), citric acid and crystalline, completely hydrated, synthetically prepared zealot builders having a particle diameter in the range from Owl to 10, preferably from Owl to 4 micrometers.
Suitable zealot builders are ZEALOT A, X and P. Mixtures of detergent builders can also be used.
The compositions herein can additionally contain, as an optional ingredient, a cat ionic surfactant. Suitable catlonic surfactant species for use herein are described in European Patent application 0.028.865, page 5, line 32 to page 7 line 21, The cat ionic surfactants can provide and/or enhance a broad range of textile treatment benefits inclusive of cleaning, feel, and bactericidal advantages. These optional cat ionic surface-active agents are used in additive levels, such as in levels not exceeding 10% of the cumulative amount of anionic and non ionic surfactants defined herein before, and more preferred in a range from 1% to 5% of the detergent composition.
.. . . . .. . . . _ I
THE-LIQUID CARRIER
The compositions herein contain as a further essential component a liquid carrier, possibly a mixture of liquid carriers.
The liquid carrier component can be represented by water and conventional liquid organic carriers. Non-limiting examples of the like organic carriers include lower aliphatic alcohol having from 2 to about 6 carbon atoms and 1 to 3 hydroxyl groups ; ethers of diethylene glycol and lower aliphatic mono-alcohols having from 1 to 4 carbon atoms and mixtures thereof.
Specific examples of liquid carriers are : ethanol;
n-propanol; isopropanol; buttonhole; 1,2-propanediol; 1,3-propanediol;
n-hexanol; monomethyl-, -ethyl-, -propel, and mono-butyl ethers and di-ethylene glycol. Other organic solvents having a relatively high boiling point and low vapor pressure can also be used, provided they do not react with any of the other ingredients present.
The relative quantities of liquid carriers needed to insure the liquid state of the composition can vary depending upon the qualitative and quantitative ingredient parameters in a given composition. However, the adequate choice of the carrier is based on routine determinations well-known in the art.
I
THE ORGANO-FUNCTIONAL SELECTION
The essential organo-functional selection for use herein can be present in levels from 0.05~ to 5%, preferably from 0.1% - 3%, and most preferably from 0.15~ - 1%. Using levels below 0.05% will not anymore produce, to any noticeable extent, the claimed benefits whereas the incorporation of levels exceeding I will not produce additional benefits commensurate with (proportional to) the level increase.
The organo-functional-polydi-Cl alkali selection component can stoichiometrically be defined with the aid of the following formula:
R R R
R- -- So - - O -I So - O So R
R _ R
Con I wherein R = Of alkali; n is an integer from 1 to 6;
Z is N\ whereby X and Y are, selected independently, X Y -H; -Of alkali; -Charlie;
~C5_6~cycloalkyl; -Clown; -CO - R; with the proviso the the nitrogen can be quaternized such as to represent/N\-W, whereby W can be selected from X and Y
X Y
or Z is H - C - M whereby P and M are -COO; -CO - NR'2; or H - P
-CO - OR' and wherein R' is hydrogen or Of alkali;
with the proviso that the degree of substitution, i.e. the molar proportion of silicones carrying a substituent other than a Of alkali group to total silicones is in the range from 0.01 to 0.7, preferably from 0.02 - 0.3.
~2;3;2'~:~2 The selection component is preferably represented by amino-functional polydialkylsiloxanes which are frequently used In levels from 0.1~ to 3%, more preferably from 0.15 - 1.0%.
The degree of substitution of preferred selections, such as the aminosiloxanes, can be expressed as the molar (moiety) proportion of non-terminal silicones carrying a substituent other than a Of 4 alkyd group to total non-terminal silicones. The numerical value for the degree of substitution of preferred selections lies in the range from 0.01 to 0.7; preferably from 0.02 to 0.3. Whole noneternal substitution is preferred for enhanced through-the-wash fiber substantivity, it is understood that selections with substituted terminal silicone atoms can also be used.
In the preferred selection component herein, n is 3 or 4, X and Y are, selected independently, hydrogen; - Of alkali; - C5 6-cycloalkyl and -C2-NH2.
Preferred organofunctional polydimethyl selections include amino functional selections, such as :
- Abbreviated - (N-cyclohexylamino - 4 amino - bottle polydimsthylsiloxane Swahili - (Ethylene Damon -N- butyl-l)polydimethylsiloxane Swahili - (N-dodecyl - 4 amino - butyl-l)polydimethylsiloxane Swahili - (4 - (N, N-dimethyl ammonium) - bottle polydimethylsiloxane Sylvia - (5 (tallow aside) - 4 - car boxy - ponytail polydimethylsiloxane Sylvia The organofunctional selections have generally a viscosity in the range from 40 cyst to 100.000 cyst, preferably from 250 cyst to 2000 cyst. The viscosity of the selections is measured on the pure raw material at 25C with the aid of a BACKFILLED viscometer (LO
Digital).
324~
The organofunctional polydimethyl selections, in addition to the essential substituents defined herelnbefore, can contain polyalkylene oxide chains attached to unsubstituted silicone atom (in the meaning of this invention). The polyalkylene, finch as propylene or ethylene, oxide chains are attached to the silicone atoms instead of a Of 4 alkyd group. The alkoxylation enhances the hydrophilic and antistatic charge reducing properties of the component in relation to the textiles.
OPTIONAL INGREDIENTS
In addition to the essential components, the composl~ions herein can contain a serves of optional detergent ingredients with a view to improve the composition taking into consideration the specific utilization. These optional components can be presented by virtually all substances, which are known to suitable for use in the like composition, for their known functionality in the art established levels.
The non-built or built compositions of the invention can contain, in addition to the detergent builder, other types of sequestrants, having precipitation inhibitor or anti incrustation properties, in varying levels e.g. in an amount from 0.2~ to I Such further sequestrants can be water-soluble copolymeric ingredients e.g. :
polyacrylates, polymaleates and copolymeric carboxylates including those obtained from the copolymerization of unsaturated palisades such a malefic or citraconic acid with suitable polymerlzable reaction partners such as methacrylic acid, acrylic acid, mesa conic acid and methyl-vinyl-ether. Mixture50f the like water-soluble detergent sequestrants can also be used.

Examples of other optional components are detergent enzymes such as pro teases, amylases, lapses and mixtures thereof, and stabilizing agents for the like enzymes., soil suspending agents such as sodium carboxymethylcellulose and polyvinylpyrrolidone~suds regulants, such as C16_22 fatty acids and methylated polysiloxanes, especially dimethylpolysiloxane, said silicone being used preferably at levels from 0.01% to 0.4%.
Hydrotropes can also be used and are frequently desirable in built compositions. Examples of suitable hydrotropes include the wa~er-soluble alkylaryl sulfonates having up to 3 carbon atoms in an alkyd group such as sodium, potassium, ammonium, and ethanol amine salts of zillion-, Tulane-, ethylbenzene- and isopropyl Bunsen sulfonic acids.
The subject compositions further can comprise brighteners, perfumes, dyes, bactericidal agents, antioxidant, pacifiers, photo activators, fillers and the like.

THE ORGANO-FUNCTIONAL SELECTION
The essential organo-functional selection for use herein can be present in levels from 0.05~ to 5%, preferably from 0.1% - 3%, and most preferably from 0.15~ - 1%. Using levels below 0.05% will not anymore produce, to any noticeable extent, the claimed benefits whereas the incorporation of levels exceeding I will not produce additional benefits commensurate with (proportional to) the level increase.
The organo-functional-polydi-Cl alkali selection component can stoichiometrically be defined with the aid of the following formula:
R R R
R- -- So - - O -I So - O So R
R _ R
Con I wherein R = Of alkali; n is an integer from 1 to 6;
Z is N\ whereby X and Y are, selected independently, X Y -H; -Of alkali; -Charlie;
~C5_6~cycloalkyl; -Clown; -CO - R; with the proviso the the nitrogen can be quaternized such as to represent/N\-W, whereby W can be selected from X and Y
X Y
or Z is H - C - M whereby P and M are -COO; -CO - NR'2; or H - P
-CO - OR' and wherein R' is hydrogen or Of alkali;
with the proviso that the degree of substitution, i.e. the molar proportion of silicones carrying a substituent other than a Of alkali group to total silicones is in the range from 0.01 to 0.7, preferably from 0.02 - 0.3.
~2;3;2'~:~2 The selection component is preferably represented by amino-functional polydialkylsiloxanes which are frequently used In levels from 0.1~ to 3%, more preferably from 0.15 - 1.0%.
The degree of substitution of preferred selections, such as the aminosiloxanes, can be expressed as the molar (moiety) proportion of non-terminal silicones carrying a substituent other than a Of 4 alkyd group to total non-terminal silicones. The numerical value for the degree of substitution of preferred selections lies in the range from 0.01 to 0.7; preferably from 0.02 to 0.3. Whole noneternal substitution is preferred for enhanced through-the-wash fiber substantivity, it is understood that selections with substituted terminal silicone atoms can also be used.
In the preferred selection component herein, n is 3 or 4, X and Y are, selected independently, hydrogen; - Of alkali; - C5 6-cycloalkyl and -C2-NH2.
Preferred organofunctional polydimethyl selections include amino functional selections, such as :
- Abbreviated - (N-cyclohexylamino - 4 amino - bottle polydimsthylsiloxane Swahili - (Ethylene Damon -N- butyl-l)polydimethylsiloxane Swahili - (N-dodecyl - 4 amino - butyl-l)polydimethylsiloxane Swahili - (4 - (N, N-dimethyl ammonium) - bottle polydimethylsiloxane Sylvia - (5 (tallow aside) - 4 - car boxy - ponytail polydimethylsiloxane Sylvia The organofunctional selections have generally a viscosity in the range from 40 cyst to 100.000 cyst, preferably from 250 cyst to 2000 cyst. The viscosity of the selections is measured on the pure raw material at 25C with the aid of a BACKFILLED viscometer (LO
Digital).
324~
The organofunctional polydimethyl selections, in addition to the essential substituents defined herelnbefore, can contain polyalkylene oxide chains attached to unsubstituted silicone atom (in the meaning of this invention). The polyalkylene, finch as propylene or ethylene, oxide chains are attached to the silicone atoms instead of a Of 4 alkyd group. The alkoxylation enhances the hydrophilic and antistatic charge reducing properties of the component in relation to the textiles.
