BLOCKY CATIONIC ORGANOPOLYSILOXANE

FIELD OF THE INVENTION

The present invention relates to inventive blocky cationic organopolysiloxane compounds. It also relates to consumer product compositions comprising the inventive compounds and to methods of making and use.

BACKGROUND OF THE INVENTION

Cationic conditioning polymers meant for deposition onto negatively charged surfaces, such as fabric, skin, or hair, are included in many common consumer product compositions. Such products can provide consumer-desired benefits such as softness, lubricity, hand, anti-wrinkle, hair conditioning, frizz control, skin moisturization, and color protection. The effectiveness of any particular conditioning polymer depends not only upon the chemical and physical properties of the conditioning polymer itself, but also upon those of the targeted surface and the product formulation in which the conditioning polymer is delivered.

Many consumer products containing cationic conditioning polymers are in the form of aqueous-based rinse-off compositions, such as hair shampoos, body washes, laundry detergents, and fabric softeners. Despite the popularity of these rinse-off compositions, such product forms frequently experience difficulties effectively depositing these cationic conditioning polymers, which are typically hydrophobic, onto the target surfaces.

Incorporating these conditioners into aqueous-based products often results in the conditioner being preferentially rinsed away from the intended site of deposition, rather than effectively deposited. This problem is particularly pronounced in the context of cleansing compositions containing surfactant, especially those containing anionic surfactant.

Anionic surfactants can interfere with deposition by forming complexes/precipitates with the cationic conditioning polymers. The higher the concentration of anionic surfactant, the more difficult it becomes to deposit cationic benefit actives. This leads to non-cost- effective use and waste of materials. Further, even if an acceptable level of deposition is attained, these formulations may lack shelf- stability due to flocculation and precipitation, making them unacceptable as consumer products.

Several materials exist in the art, but are not wholly satisfactory. For example, the material described by Ono (WO 99/32539) comprises functionalized end groups having heteroatoms such as oxygen, nitrogen, sulfur, or halogens. These functionalized end groups can lead to undesirable reactions that pose stability issues for compositions comprising these materials. For instance, Ono's silicones can react further through these end groups, leading to further condensation and/or polymerization of the silicones in the compositions during storage.

Also known in the art are quaternized silicones that include alkylene oxide units, such as those described by Masschelein (U.S. Patent No. 6,903,061). The quaternized silicones described by Masschelein may be too water soluble for a given application, and thus can have a reduced capacity as conditioning polymers, since these materials tend to partition into water at a higher than desired level rather than deposit on the target substrate. Further, when these materials are used as the conditioning active, they can have an undesirable feel because of their high permeability to water and water vapor. Additionally, because of the potential for variability in the alkylene oxide moiety, these materials can be difficult to formulate reproducibly. This can limit the desired degree of functionality in a silicone material. It would desirable to have a material the provides greater flexibility via the level of

quaternization. Similarly, the ethoxylated quaternized silicone materials disclosed by

Boutique (U.S. Patent No. 6,833,344) suffer from many of the same inadequacies of those described by Masschelein.

There is still a need to provide cationic conditioning polymers that are suitable for use in a wide range of consumer product applications. The present invention provides cationic conditioning polymers and consumer product compositions comprising conditioning polymers that can effectively deposit and provide conditioning benefits to negatively charged substrates while avoiding the aforementioned disadvantages.

SUMMARY OF THE INVENTION

The present invention attempts to solve one or more of the aforementioned needs by providing, in one aspect, inventive blocky cationic organopolysiloxanes that are suitable for use in a wide range of consumer product compositions. The inventive compounds are functionalized to favorably interact with the targeted substrate and product composition to deliver desired deposition and conditioning benefits, as well as desired shelf- stability.

Without being bound by theory, when cationic charge that could otherwise facilitate hydrophobic benefit agent deposition is randomly distributed along the length of the benefit agent polymer, the charge can be too highly dispersed to adequately facilitate deposition. The inventive polymer's charge density can be custom-tailored (e.g., higher charge density) to enhance deposition and conditioning performance in different use environments. Further, by varying the inventive polymer' s level of hydrophobic substitution and/or the degree of ethoxylation, propoxylation, and alkoxylation, the inventive polymer can be formulated into a desirably stable composition for a variety of use environments. By controlling charge density and hydrophobic substitution and/or degree of ethoxylation, propoxylation, and more generally alkoxylation, the inventive compounds can be custom-tailored for a variety of product formulations and uses.

The current invention further solves the aforementioned needs by providing blocky cationic organosiloxanes comprised of multiple blocks of cationic portions and un-charged silicone portions as components of the same organopolysiloxane polymer. Without being bound by theory it is felt that these multi-block organopolysiloxanes offered a preferable solution to the aforementioned needs in that any of the multiple cationic portions of the organopolysiloxane can form a first interaction with the target surface, thereby faciltaing the further adherence of subsequent cationic portions of the same molecule with the target surface , and that as such, the overall deposition of the organopolysolixane on the target surface is enhanced.

DETAILED DESCRIPTION OF THE INVENTION I. DEFINITIONS

As used herein, the "blocky cationic organopolysiloxane" may also be referred to as the "organopolysiloxane".

As used herein "consumer product" means baby care, personal care, fabric & home care, family care (e.g., facial tissues, paper towels), feminine care, health care, beauty care and like products generally intended to be used or consumed in the form in which they are sold.

All of such products, as applicable, may be in standard, concentrated or even highly concentrated form even to the extent that such products may in certain aspects be non-aqueous.

As used herein, articles such as "a" and "an" are understood to mean one or more of what is claimed or described. As used herein, the terms "include", "contain", and "have" are non-limiting and do not exclude other components or features beyond those expressly identified in the description or claims.

As used herein, the terms "treatment agent", "benefit agent", "active", "active agent", and/or "care agent" and the like are used interchangeably to mean materials that can impart desirable aesthetic and/or functional properties (e.g., conditioning benefits such as softening or freshening) to a substrate. For example, the inventive organopolysiloxane polymer of the present invention can be used as a conditioning agent to impart conditioning benefits to substrates.

As used herein, the terms "conditioning agent" and "conditioning aid" are used interchangeably to refer to a material that delivers desirable conditioning effects (e.g., benefits such as softening or freshening) to a substrate. Conditioning agents are a type of treatment agent.

As used herein, the term "conditioning polymer" means a polymer that delivers desirable conditioning effects (e.g., softening or freshening) to a substrate.

As used herein, the term "substrate" is synonymous and used interchangeably with the terms "situs" and "surface". Non-limiting examples of substrates include paper products, fabrics, garments, hard surfaces, hair, and skin.

As used herein, "targeted substrate" means a substrate, or the relevant portion of a substrate, upon which deposition is intended.

As used herein, a "deposition aid" is a material that assists another material (e.g., a benefit agent) to deposit (e.g., adhere) to a targeted substrate. The term "deposition aid" is broad enough to encompass both polymeric deposition aids (i.e. "deposition polymer") and non-polymeric deposition aids.

As used herein, "adjunct" means an optional material that can be added to a composition to complement the aesthetic and/or functional properties of the composition.

As used herein, "auxiliary composition" refers to one or more compositions that when combined with a benefit agent emulsion of the present invention, form a consumer product composition. The auxiliary composition may be in the form of one or more ingredients or ingredient combinations.

As used herein, "carrier" means an optional material, including but not limited to a solid or fluid, that can be combined with a benefit agent (e.g., conditioning polymers) to facilitate delivery and/or use of the benefit agent. As used herein, the term "solid" includes granular, powder, bar and tablet product forms.

Unless specified otherwise, all molecular weights are given in Daltons.

Unless otherwise indicated, all molecular weights are weight average molecular weights as determined by size exclusion chromatography using a MALS detector (SEC- MALS), as is commonly known by those skilled in the art. A MALS detector (Multi- Angle Light Scattering Detector, such as those manufactured by Malvern Instruments Ltd., Malvern, UK) determines absolute molecular weight, rather than relative molecular weight (i.e., determined relative to a standard).

Unless otherwise noted, all component (i.e., ingredient) or composition levels are in reference to the active portion of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources of such components or compositions.

The term "charge density", as used herein, refers to the ratio of the number of positive charges on a monomeric unit of which a polymer is comprised, to the molecular weight of said monomeric unit. The charge density multiplied by the polymer molecular weight determines the number of positively charged sites on a given polymer chain. The charge density calculation can also be expressed as:

(moles of N ) (charge per N)

charge density = — — — x 100

(moles of polymer) (molecular weight of the polymer)

As used herein, the term "hydrocarbon polymer radical" means a polymeric radical comprising only carbon and hydrogen.

As used herein, "ethylene moiety" means a divalent CH ₂ CH ₂ moiety. As used herein, the term "siloxyl residue" means a polydialkylsiloxane moiety.

As used herein, the nomenclature SiO _n/ 2 represents the ratio of oxygen and silicon atoms. For example, S1O1 _/ 2 means that, on average, one oxygen atom is shared between two silicon atoms.

METHODS OF MAKING THE BLOCKY CATIONIC ORGANOPOLYSILOXANE

Embodiments of the present invention can be made as follows. An amount of functional silicone is added to a clean vessel under inert atmosphere. The functional silicone may be an amino functional silicone or a silicone with an organic group capable of reacting with an amino function, examples of organic groups capable of reacting with an amino function include halogen finctional silicone or an epoxy functional silicone. Optionally, a solvent such as isopropanol or tetrahydrofuran is added. The reaction is optionally mixed and quantities of diamine and difunctional organic compounds capable of reacting with the amino functions of the amine compounds are added, either simultaneously or sequentially. For example, the difunctional organic compound capable of reacting with the amino function may be added first and the diamine added second, to obtain the desired organopolysiloxane. Alternately, these reagents may be added in reverse order.

The reaction is run at a temperature appropriate for the reagents. For example, when the difunctional organic compound capable of reacting with the amino functions is a dichloride, the reaction may be run at relatively higher temperatures (typically above 60°C and often above 80°C). Alternately, when the difunctional organic compound capable of reacting with the amino functions is a dibromide, the reaction may be run at relatively lower temperatures, including at room temperature (e.g., 21°C). Alternately, when the difunctional organic compound capable of reacting with the amino functions is an activated dichloride, the reaction may be run at relatively lower temperatures, including at room temperature (e.g., 21°C). One of ordinary skill in the art would understand the reaction conditions suitable for the specific difunctional organic compound capable of reacting with the amino functions.

The above making process is also generally described by Lange (U.S. Patent No. 7,563,856). One skilled in the art would understand how the general process disclosed in Lange can be reapplied to the present development in order to produce the organopolysiloxanes of the present invention.

In one embodiment, the reaction is run without the addition of solvent, resulting in a substantially solvent-free process for making the organopolysiloxane of the present invention.

In another embodiment, the reaction is run and subsequently excess amine is added.

Without being bound by theory, it is believed that the excess amine will consume the reactive groups of any residual difunctional organic compounds capable of reacting with the amino functions.

In another embodiment, the reaction mixture is further reacted with an amine containing molecule. Non-limiting examples of such amines include ammonia, methylamine, dimethylamine, trimethylamine, triethylamine or ethanolamine or diethanolamine. Without being bound by theory it is believed that this further reaction caps un-reacted akyl-halide functionality.

In another embodiment, the reaction mixture is further reacted with a mono-functional organic species capable of reacting with the amine functionality of the organopolysiloxane. Non-limiting examples of such mono-functional organic species include: methyl bromide, methyl iodide, and ethylbromide. Without being bound by theory it is believed that this further reaction helps to quaternize any residual neutral amine groups of the organopolysiloxane, including the terminal amine functionality.

IV. USES OF THE ORGANOPOLYSILOXANE COMPOSITIONS

The organopolysiloxanes according to the present invention can be formulated into a variety of consumer product compositions that can be applied to substrates in order to impart consumer-desired benefits, such as conditioning. Such substrates can include fabric, non- woven materials, paper products, hard surface materials, and biological materials (e.g., keratinous materials such as hair or skin).

The consumer product compositions comprising the organopolysiloxane polymers of the present invention may be prepared by any suitable process, such as processes known by those skilled in the art. For example, the organopolysiloxane polymers can be incorporated directly into the composition's other ingredients without pre-emulsification and/or pre- mixing to form the finished products. Alternatively, the organopolysiloxane may be mixed with surfactants, solvents, suitable adjuncts, and/or any other suitable ingredients to prepare emulsions prior to compounding the finished products.

The consumer product composition can comprise one or more surfactants. The surfactants may comprise cationic, anionic, non-ionic, zwitterionic, and/or amphoteric surfactants. In one embodiment, at least one surfactant is anionic. Various forms of the consumer product composition can be aqueous or non-aqueous; in one embodiment, an aqueous composition has a pH greater than 3, or greater than 5.
