This invention relates to compositions comprising hydrophobically modified cationic polymers as well as processes of making and using such compositions.
Consumer products typically comprise benefit agents that provide, for example, freshness, feel, anti-dandruff benefits, etc. Such benefit agents are typically expensive and/or can bring negatives such as stability negatives, particularly when such benefit agents are used at high levels. As a result, the industry has attempted to increase the effectiveness of such benefit agents via increasing the deposition of such benefit agents through the use of a deposition aid. Unfortunately, deposition aids, while increasing the deposition of the desired benefit agent, can also increase the deposition of undesired materials such as soil and/or alter the nature of the desired benefit agent. When the deposition aid deposits soil; whiteness, feel, and/or cleaning benefits are decreased. When the nature of the desired benefit agent is negatively impacted by the deposition aid, the benefit agent's effectiveness may be decreased and/or the consumer experience arising from the benefit agent's use may be altered in a negative manner. For several decades the contradiction between effective benefit agent deposition and undesired deposition of materials, such as soil, has not been sufficiently resolved.
Applicants recognized that deposition aids undergo hydrophobic and/or electrostatic interactions with not only benefit agents, but also materials, such as soils, to form particulates that have an affinity for consumer relevant substrates such as hair, skin, fabrics, and/or hard surfaces. Such interactions may be particularly pronounced in the presence of surfactants. Thus, Applicants recognized the source of the problem that has been the barrier to the resolution to benefit agent deposition without and/or minimized deposition negatives. As a result of such recognition, Applicants provide a solution to such aforementioned problem herein.
This invention relates to compositions comprising hydrophobically modified cationic polymers as well as processes of making and using such compositions.

In one aspect of the compositions disclosed herein comprise a perfume and or perfume delivery system. As used herein the term “perfume” is used to indicate any odoriferous material that is subsequently released into the aqueous bath and/or onto fabrics contacted therewith. Suitable perfume delivery systems, methods of making perfume delivery systems and the uses of perfume delivery systems are disclosed in USPA 2007/0275866 A1. Such perfume delivery systems include:
I. Polymer Assisted Delivery (PAD):
This perfume delivery technology uses polymeric materials to deliver benefit agents (e.g., perfumes). Examples of PAD include employment of classical coacervation, water soluble or partly soluble to insoluble charged or neutral polymers, liquid crystals, hot melts, hydrogels, perfumed plastics, microcapsules, nano- and micro-latexes, polymeric film formers, and polymeric absorbents, polymeric adsorbents, etc. Further, PAD includes but is not limited to:
a.) Matrix Systems: The benefit agent is dissolved or dispersed in a polymer matrix or particle. Perfumes, for example, may be 1) dispersed into the polymer prior to formulating into the product or 2) added separately from the polymer during or after formulation of the product. Examples include those with amine functionality, which may be used to provide benefits associated with amine-assisted delivery (AAD) and/or polymer-assisted delivery (PAD) and/or amine-reaction products (ARP).
b.) Reservoir Systems: Reservoir systems are also known as a core-shell system (e.g., perfume microcapsules). In such a system, the benefit agent is surrounded by a benefit agent release controlling membrane, which may serve as a protective shell. Suitable shell materials include reaction products of one or more amines with one or more aldehydes, such as urea cross-linked with formaldehyde or gluteraldehyde, melamine cross-linked with formaldehyde; gelatin-polyphosphate coacervates optionally cross-linked with gluteraldehyde; gelatin-gum Arabic coacervates; cross-linked silicone fluids; polyamine reacted with polyisocyanates, polyamines reacted with epoxides, polyvinyl alcohol cross linked with gluteraldehyde, polydivinyl chloride, polyacrylate, in one aspect said polyacrylate based materials may comprise polyacrylate formed from methylmethacrylate/dimethylaminomethyl methacrylate, polyacrylate formed from amine acrylate and/or methacrylate and strong acid, polyacrylate formed from carboxylic acid acrylate and/or methacrylate monomer and strong base, polyacrylate formed from an amine acrylate and/or methacrylate monomer and a carboxylic acid acrylate and/or carboxylic acid methacrylate monomer, and mixtures thereof.
Suitable core materials include perfume compositions, and/or perfume raw materials, Suitable perfume compositions may comprise enduring perfumes, such as perfume raw materials that have a cLogP greater than about 2.5 and a boiling point greater than about 250° C. Further, suitable perfume compositions may comprise blooming perfumes that comprise perfume raw materials that have a cLogP of greater than about 3 and a boiling point of less than about 260° C.
Suitable core materials being stabilized, emulsified, in the solvent systems with organic or inorganic materials, organic materials can be polymers of anionic, non-ionic nature or cationic nature, like polyacrylates, polyvinyl alcohol. Suitable processes to make core shell systems include coating, extrusion, spray drying, interfacial polymerization, polycondensation, simple coacervation, complex coacervation, free radical polymerization, in situ emulsion polymerization, matrix polymerization and combinations thereof.
Suitable characteristics for core shell systems include:
Suitable deposition and/or retention enhancing coatings that may be applied to the core shell systems include cationic polymers such as polysaccharides including, but not limited to, cationically modified starch, cationically modified guar, polysiloxanes, poly diallyl dimethyl ammonium halides, copolymers of poly diallyl dimethyl ammonium chloride and vinyl pyrrolidone, acrylamides, imidazoles, imidazolinium halides, imidazolium halides, poly vinyl amine, copolymers of poly vinyl amine and N-vinyl formamide and mixtures thereof. In another aspect, suitable coatings may be selected from the group consisting of polyvinylformaldehyde,
partially hydroxylated polyvinylformaldehyde, polyvinylamine, polyethyleneimine, ethoxylated
polyethyleneimine, polyvinylalcohol, polyacrylates, and combinations thereof.
Suitable methods of physically reducing any residual type materials may be employed, such as centrifugation, to remove undesirable materials. Suitable methods of chemically reducing any residual type materials may also be employed, such as the employment of scavengers, for example formaldehyde scavengers including sodium bisulfite, urea, ethylene urea, cysteine, cysteamine, lysine, glycine, serine, carnosine, histidine, glutathione, 3,4-diaminobenzoic acid, allantoin, glycouril, anthranilic acid, methyl anthranilate, methyl 4-aminobenzoate, ethyl acetoacetate, acetoacetamide, malonamide, ascorbic acid, 1,3-dihydroxyacetone dimer, biuret, oxamide, benzoguanamine, pyroglutamic acid, pyrogallol, methyl gallate, ethyl gallate, propyl gallate, triethanol amine, succinamide, thiabendazole, benzotriazol, triazole, indoline, sulfanilic acid, oxamide, sorbitol, glucose, cellulose, poly(vinyl alcohol), partially hydrolyzed poly(vinylformamide), poly(vinyl amine), poly(ethylene imine), poly(oxyalkyleneamine), poly(vinyl alcohol)-co-poly(vinyl amine), poly(4-aminostyrene), poly(1-lysine), chitosan, hexane diol, ethylenediamine-N,N′-bisacetoacetamide, N-(2-ethylhexyl)acetoacetamide, 2-benzoylacetoacetamide, N-(3-phenylpropyl)acetoacetamide, lilial, helional, melonal, triplal, 5,5-dimethyl-1,3-cyclohexanedione, 2,4-dimethyl-3-cyclohexenecarboxaldehyde, 2,2-dimethyl-1,3-dioxan-4,6-dione, 2-pentanone, dibutyl amine, triethylenetetramine, ammonium hydroxide, benzylamine, hydroxycitronellol, cyclohexanone, 2-butanone, pentane dione, dehydroacetic acid, or a mixture thereof.
III. Amine Assisted Delivery (AAD):
The amine-assisted delivery technology approach utilizes materials that contain an amine group to increase perfume deposition or modify perfume release during product use. There is no requirement in this approach to pre-complex or pre-react the perfume raw material(s) and the amine prior to addition to the product. In one aspect, amine-containing AAD materials suitable for use herein may be non-aromatic; for example, polyalkylimine, such as polyethyleneimine (PEI), or polyvinylamine (PVAm), or aromatic, for example, anthranilates. Such materials may also be polymeric or non-polymeric. In one aspect, such materials contain at least one primary amine. In another aspect, a material that contains a heteroatom other than nitrogen, for example sulfur, phosphorus or selenium, may be used as an alternative to amine compounds. In yet another aspect, the aforementioned alternative compounds can be used in combination with amine compounds. In yet another aspect, a single molecule may comprise an amine moiety and one or more of the alternative heteroatom moieties, for example, thiols, phosphines and selenols.
IV. Pro-Perfume (PP):
This technology refers to perfume technologies that result from the reaction of perfume materials with other substrates or chemicals to form materials that have a covalent bond between one or more PRMs and one or more carriers. The PRM is converted into a new material called a pro-PRM (i.e., pro-perfume), which then may release the original PRM upon exposure to a trigger such as water or light. Nonlimiting examples of pro-perfumes include Michael adducts (e.g., beta-amino ketones), aromatic or non-aromatic imines (Schiffs Bases), oxazolidines, beta-keto esters, and orthoesters. Another aspect includes compounds comprising one or more beta-oxy or beta-thio carbonyl moieties capable of releasing a PRM, for example, an alpha, beta-unsaturated ketone, aldehyde or carboxylic ester.
a.) Amine Reaction Product (ARP): For purposes of the present application, ARP is a subclass or species of PP. One may also use “reactive” polymeric amines in which the amine functionality is pre-reacted with one or more PRMs, typically PRMs that contain a ketone moiety and/or an aldehyde moiety, to form an amine reaction product (ARP). Typically, the reactive amines are primary and/or secondary amines, and may be part of a polymer or a monomer (non-polymer). Such ARPs may also be mixed with additional PRMs to provide benefits of polymer-assisted delivery and/or amine-assisted delivery. Nonlimiting examples of polymeric amines include polymers based on polyalkylimines, such as polyethyleneimine (PEI), or polyvinylamine (PVAm). Nonlimiting examples of monomeric (non-polymeric) amines include hydroxyl amines, such as 2-aminoethanol and its alkyl substituted derivatives, and aromatic amines such as anthranilates. The ARPs may be premixed with perfume or added separately in leave-on or rinse-off applications. In another aspect, a material that contains a heteroatom other than nitrogen, for example oxygen, sulfur, phosphorus or selenium, may be used as an alternative to amine compounds. In yet another aspect, the aforementioned alternative compounds can be used in combination with amine compounds. In yet another aspect, a single molecule may comprise an amine moiety and one or more of the alternative heteroatom moieties, for example, thiols, phosphines and selenols.
