Definitions
- This invention relates to liquid laundry detergent compositions containing functionalized silicone materials as fabric care agents.
- Such fabric care benefits to be imparted can be exemplified by one or more of reduction, prevention or removal of wrinkles; the improvement of fabric softness, fabric feel or garment, shape retention or recovery; improved elasticity; ease of ironing benefits; color care; anti-abrasion; anti-pilling; or any combination of such benefits.
- Detergent compositions which provide both fabric cleaning performance and additional fabric care effects, e.g., fabric softening benefits are known as "2-in- 1 "-detergent compositions and/or as "softening-through-the-wash"-compositions.
- quaternary ammonium fabric softening agents e.g., quaternary ammonium fabric softening agents
- One such type of alternative fabric care agents comprises silicone, i.e., polysiloxane-based, materials. Silicone materials include nonfunctional types such as polydimethylsiloxane (PDMS) and functionalized silicones, and can be deposited onto fabrics during the wash cycle of the laundering process. Such deposited silicone materials can provide a variety of benefits to the fabrics onto which they deposit. Such benefits include those listed hereinbefore.
- Non-functionalized silicones however good in their compatibility with detergents, have shortcomings. Such non-functionalized silicones can produce excellent fabric care benefits when directly applied to textiles, yet are found to work ineffectively in liquid laundry detergents. The problem is a complex one and includes inadequate deposition in the presence of surfactants, unsatisfactory spreading, inadequate emulsion stability and other factors. When such nonfunctional materials do not deposit effectively, a major proportion of the silicone is lost to the drain at the end of the wash, rather than being deposited evenly and uniformly on the fabrics, e.g., clothing, being washed.
- amino and “ammonium” in this context most generally means that there is at least one substituted or unsubstituted amino or ammonium moiety covalently bonded to, or covalently bonded in, a polysiloxane chain and the covalent bond is other than an Si-N bond, e.g., as in the moieties - [Si]-O-CRVNR 3 , -[Si]-O-CR' 2 -NR 3 -[Si]-OCR' 2 -N + R 4 , -[Si]-OCR' 2 -N HR 2 -[Si]-O-CR' 2 - N + HR 2 -[Si]-CRVNR 3 etc.
- Functionalized, nitrogen-containing silicones such as these can be used in and of themselves to impart a certain amount and degree of fabric care benefit.
- functionalized silicones also have shortcomings. For example it is known that they can react chemically with components of detergents. Mechanisms of reaction have not been well documented but can in principle include reactions of aminofunctional groups themselves, as well as reactions of curable groups present within such functionalized polymers. The art is ambivalent on the possibility of successfully including reactive or curable silicones in detergents without stability problems.
- references teaching desirablity of having curable or reactive moieties and on the other hand there are references teaching desirability of avoiding all reactive moieties (in this context including ammonium or aminofunctional moieties) in various cleaning compositions.
- nitrogen-containing silicone materials useful as fabric care agents can be prepared from nitrogen-substituted alkoxysilanes or alkoxysiloxanes as starting materials. (See for example, the processes disclosed in EP-A-269,886 and US-A-6,093,841.) Such preparation can involve hydrolysis of the starting materials followed by catalytic equilibration and condensation with non-functionalized siloxanes. Depending on the process involved and conditions used, the resulting amino or ammonium functionalized silicones will contain reactive groups on the silicon atoms, and especially the terminal silicon atoms, of the siloxane chains in such reaction product material.
- Such reactive groups can comprise -H, -OH, and -OR moieties originally present in the silane and siloxane starting materials.
- synthesis routes such as the above, found desirable for manufacturing reasons, can be applied to the provision of improved fabric care detergents.
- Processes which remove reactive groups from the functionalized silicone end product serve to render those end products "nonreactive.”
- it is desirable to conduct such additional processes only to the minimum extent required for good liquid detergent fabric care benefit performance and stability, or the processes are wasteful and costly.
- a silicone blend of preferably miscible silicones comprising certain amino and ammonium functionalized silicone material in combination with certain kinds of non-functionalized polysiloxanes.
- the amino and ammonium functionalized silicones used are those which have been prepared in a manner to minimize the presence therein of certain types of reactive moieties.
- These selected amino and ammonium functionalized silicones are also those which have a specific balance of amine and or ammonium functionality, as quantified by nitrogen content, and silicone viscosity and preferably molecular weight.
- the nitrogen content is fundamentally linked to the ability to obtain miscibility of the functionalized and non-functionalized silicones, and the blend combination of the two acts synergistically. Moreover, while the levels of reactive group content needed are low, they do not need to be zero. This is believed to be due, at least in part, to the ability of the non- functionalized silicone to protect the functionalized silicone from interaction with other components of the detergent composition. Furthrmore, use of combinations of functionalized and non-functionalized silicones also permits formulation of liquid detergent products which do not need to contain a cationic deposition aid or a coacervate phase-forming polymer in order to promote deposition of the silicone materials onto fabrics.
- the present invention therefore offers numerous advantages.
- Fourth, the compositions are stable and effective for their intended industrial purposes. Other advantages include that the compositions are non-yellowing on white textiles and moreover, that they do not give uneven deposition or lead to unacceptable visual results on clothing.
- the present invention is directed to aqueous (e.g., containing upwards of from 4% by weight water) liquid laundry detergent compositions which are suitable for cleaning and imparting fabric care benefits to fabrics laundered using such a composition.
- aqueous e.g., containing upwards of from 4% by weight water
- Such compositions comprise:
- At least one detersive surfactant selected from anionic surfactants, nonionic surfactants, zwitterionic surfactants, amphoteric surfactants, and combinations thereof;
- the specific amino and/or ammonium functionalized polysiloxane materials used are those which have been prepared by a process which intrinsically leaves reactive/curable groups in the functionalized polysiloxane material which is produced.
- a process which intrinsically leaves reactive/curable groups in the functionalized polysiloxane material which is produced.
- a process comprises hydrolysis of nitrogen-containing alkoxysilane and or alkoxysiloxane starting materials and catalytic equilibration and condensation of these hydrolyzed starting materials. Notwithstanding the tendency of the process used to leave reactive/curable groups within the resulting functionalized polysiloxane materials, such materials must be further processed in a manner which reduces and minimizes the amount of such reactive/curable groups which remain.
- the amino and/or ammonium functionalized polysiloxane materials used must have a molar ratio of curable/reactive group-containing silicon atoms to terminal silicon atoms containing no reactive/curable groups which is less than 30%. Syntheses of the functionalized silicones are adapted herein to secure appropriate curable/reactive group contents, which can theoretically be zero or, more economically, can be non-zero while remaining at low and compatible levels.
- Such amino and or ammonium functionalized polysiloxane materials also have a nitrogen content ranging from 0.05% to 0.5% by weight and a viscosity at 20 °C ranging from 0.00002 m 2 /s to 2.0 m 2 /s.
- the nitrogen-free, non-functionalized polysiloxane material which forms part of the silicone blend has a viscosity which ranges from 0.01m 2 /s to 2 i 0m 2 /s. It is present in an amount such that the weight ratio of functionalized to non-functionalized siloxanes within the silicone blend ranges from 100:1 to 1:100.
- the functionalized silicone and nitrogen-free, non- functionalized polysiloxane materials are preferably fully miscible at the specified nitrogen content of the functionalized silicone. This leads to droplets of the resulting blend which are more effective for providing fabric care benefits, e.g., softness or feel of textiles on the skin, than either of the materials alone.
- compositions are essentially free of any coacervate phase-forming polymers. Likewise such compositions are essentially free of any cationic deposition aids.
- liquid laundry detergent compositions herein as well as composition form, preparation and use, are described in greater detail as follows: In this description, all concentrations and ratios are on a weight basis of the liquid laundry detergent unless otherwise specified. Percentages of certain compositions herein, such as silicone emulsions prepared independently of the liquid laundry detergent, are likewise percentages by weight of the total of the ingredients that are combined to form these compositions. Elemental compositions such as percentage nitrogen (%N) are percentages by weight of the silicone referred to.
- %N percentage nitrogen
- Particle size ranges are ranges of median particle size.
- a particle size range of from 0.1 micron to 200 micron refers to the median particle size having a lower bound of 0.1 micron and an upper bound of 200 microns.
- Particle size may be measured by means of a laser scattering technique, using a Coulter LS 230 Laser Diffraction Particle Size Analyser from Coulter Corporation, Miami, Florida, 33196, USA.
- Viscosity is measured with a Cammed CSL2 Rheometer at a shear rate of 21 sec "1 . Viscosity expressed in m 2 /sec can be multiplied by 1,000,000 to obtain equivalent values in Centistokes (Cst). Viscosity expressed in Cst can be divided by 1,000,000 to obtain equivalent values in m 2 /sec. Additionally, Kinematic viscosity can be converted to Absolute viscosity using the following conversion: multiply kinematic viscosity given in centistokes by density (grams/cm 3 ) to get absolute viscosity in centipoise (cp or cps).
- the present compositions comprise as one essential component at least one surfactant selected from the group consisting anionic surfactants, nonionic surfactants, zwitterionic surfactants, amphoteric surfactants, and combinations thereof.
- the surfactant component can be employed in any concentration which is conventionally used to effectuate cleaning of fabrics during conventional laundering processes such as those carried out in automatic washing machines in the home. Suitable surfactant component concentrations include those within the range from 5% to 80%, preferably from 7% to 65%, and more preferably from 10% to 45%, by weight of the composition.
- any detersive surfactant known for use in conventional laundry detergent compositions may be utilized in the compositions of this invention.
- Such surfactants for example include those disclosed in "Surfactant Science Series", Vol. 7, edited by W. M. Linfield, Marcel Dekker.
- Non- limiting examples of anionic, nonionic, zwitterionic, amphoteric or mixed surfactants suitable for use in the compositions herein are described in McCutcheon's, Emulsifiers and Detergents, 1989 Annual, published by M. C. Publishing Co., and in U.S. Patent Nos. 5,104,646; 5,106,609; 3,929,678; 2,658,072; 2,438,091; and 2,528,378.
- Preferred anionic surfactants useful herein include the alkyl benzene sulfonic acids and their salts as well as alkoxylated or un-alkoxylated alkyl sulfate materials. Such materials will generally contain form 10 to 18 carbon atoms in the alkyl group.
- Preferred nonionic surfactants for use herein include the alcohol alkoxylate nonionic surfactants. Alcohol alkoxylates are materials which correspond to the general formula:
- R ⁇ is a Cg - Cjg alkyl group
- m is from 2 to 4
- n ranges from about 2 to 12.
- R* is an alkyl group, which may be primary or secondary, that contains from about 9 to 15 carbon atoms, more preferably from about 10 to 14 carbon atoms.
- the alkoxylated fatty alcohols will be ethoxylated materials that contain from about 2 to 12 ethylene oxide moieties per molecule, more preferably from about 3 to 10 ethylene oxide moieties per molecule.
- Silicone Component -
- the present compositions essentially contain droplets of a blend of certain types of silicone materials.
- This blend of silicone materials comprises both amino and/or ammonium group-containing functionalized polysiloxane materials and nitrogen- free, non-functionalized polysiloxane materials.
- polysiloxane and “silicone” can be and are herein used interchangeably.
- Both the functionalized and non-functionalized polysiloxanes used in the silicone blend are built up from siloxy units which are chosen from the following groups:
- R substituents represent organic radicals, which can be identical or different from one another.
- at least one of the R 1 groups essentially comprises nitrogen in the form of an amino or quaternary moiety, and optionally and additionally may comprise nitrogen in the form of an amide moiety so as to form an amino-amide.
- none of the R 1 groups are substituted with nitrogen in the form of an amino or quaternary ammonium moiety.
- the R 1 groups for each type of polysiloxanes correspond to those defined more particularly in one or more of the additional general formulas set forth hereinafter for these respective types of polysiloxane materials.
- these Q, T, D and M designations for these several siloxy unit types will be used in describing the preparation of the functionalized polysiloxanes in a manner which minimizes the content of reactive groups in these functionalized materials.
- These Q, T, D and M designations are also used in describing the NMR monitoring of the preparation of these materials and the use of NMR techniques to determine and confirm reactive group concentrations.
- the functionalized silicone is a polymeric mixture of molecules each having a straight, comb - like or branched structure containing repeating SiO groups.
- the molecules comprise functional substituents which comprise at least one nitrogen atom which is not directly bonded to a silicon atom.
- the functionalized silicones selected for use in the compositions of the present inventions include amino-functionalized silicones, i.e., there are silicone molecules present that contain at least one primary amine, secondary amine, or tertiary amine. Quatemized amino-functionalized silicones, i.e. quaternary ammonium silicones, are also encompassed by the definition of functionalized silicones for the purpose of the present invention.
- the amino groups can be modified, hindered or blocked in any known manner which prevents or reduces the known phenomenon of aminosilicone fabric care agents to cause yellowing of fabrics treated therewith if, for example, materials too high in nitrogen content are employed.
- the functionalized silicone component of the silicone blend will generally be straight- chain, or branched polysiloxane compounds which contain amino or ammonium groups in the side groups (i.e., the amino or ammonium groups are present in groups having general structures designated D or T) or at the chain ends (i.e., the amino or ammonium groups are present in groups having general structures designated M).
- the molar ratio of curable/reactive group-containing silicon atoms to non-curable/reactive group-containing terminal silicon atoms is from 0% to no more than 30%, i.e., 0.3 mole fraction.

- Hydroxyl- and alkoxy-containing silicon atoms in this context means all M, D, T and Q groups which contain an Si-OH or Si-OR grouping. (It should be noted that D groups which contain -OH or -OR substituents on the silicon atom will generally comprise the terminal Si atoms of the polysiloxane chain.)
- the "non-hydroxyl- or alkoxy-containing terminal silicon atoms” means all M groups which contain neither a Si-OH nor a Si-OR group.
- This molar ratio of hydroxyl- and alkoxy-containing silicon atoms to non-hydroxyl- or alkoxy-containing terminal silicon atoms is expediently determined according to the present invention by nuclear magnetic resonance (NMR) spectroscopy methods, preferably by l H-NMR and 29 Si-NMR, particularly preferably by 29 Si-NMR.

- the limit value of 0% in the context of the invention means that preferably silicon atoms containing reactive groups can no longer be detected by suitable analytical methods, such as NMR spectroscopy or infra-red spectroscopy. It should be noted that, in view of the preparative methods for the functionalized silicone materials, having no reactive groups or having them at very limited levels does not follow automatically from mere presentation of chemical structures not having such reactive groups. Rather, reactive group content must be practically secured at the specified levels by adapting the synthesis procedure for these materials, as is provided for herein.
- non-reactive chain-terminating M groups represent structures which, in the environment of the detergent formulations herein, are not capable of forming covalent bonds with a resulting increase in the molecular weight of materials formed.

- amino-functional alkoxysilanes, water, corresponding siloxanes containing M, D, T and Q units and basic equilibration catalysts initially can be mixed with one another in appropriate ratios and amounts. Heating to 60 °C to 230 °C can then be carried out, with constant thorough mixing. The alcohols split off from the alkoxysilanes and subsequently water can be removed stepwise. The removal of these volatile components and the substantial condensation of undesirable reactive groups can be promoted by using a reaction procedure at elevated temperatures and/or by applying a vacuum.
- a further process step which comprises the removal of the vaporizable condensation products, such as, in particular, water and alcohols, from the reaction mixture by means of an entraining agent.

- an example of epoxyalkylalkoxysilanes is glycidylpropylmethyldmethoxysilane
- examples of isocyanate-functionalized silanes are isocyanatopropylmethyl-diethoxysilane and isocyanatopropyltriethoxysilane. It is also possible to carry out the functionalization to amino-functional compounds at the stage of the silanes or the equilibrated siloxanes.
- Ammonia or structures containing primary, secondary and tertiary amino groups can be used in the preparation of the amino-functionalized silanes and siloxanes.
- Diprimary amines are of particular interest, and here in particular diprimary alkylamines, such as 1,6-diaminohexane and 1,12-diaminododecane, and diprimary amines based on polyethylene oxide-polypropylene oxide copolymers, such as Jeffamine ® of the D and ED series (Huntsman Corp.) can be used.

According to requirements for minimization of the end contents of reactive groups, this can again be carried out, as already described, at elevated temperature and/or with vacuum and with azeotropic distillation.
- the essential advantage of this two-stage method is that the final equilibration proceeds with substantial exclusion of e.g. water and alcohols and the contents of reactive groups in the starting substances are small and known.
