Description

FIELD OF THE INVENTION

Composition and method for covalent modification of surface properties of a substrate containing a silicone polymer, a copolymer and mixtures thereof and an active material having functional groups capable of covalently adhering to the substrate in the presence of an acid or base, a photocatalyst capable of generating an acid or base under the action of light, and a carrier .

State of the art

Materials can be characterized in terms of bulk properties and surface properties. The general properties of the material are largely controlled by the surface properties and bulk properties of the material. The surface properties of the material are largely controlled by the chemical composition of the surface and the surface structure of the material. The bulk properties of the material are largely controlled by the bulk chemical composition and bulk structure of the material. Sometimes it is desirable to modify the chemical composition of the surface and / or the surface structure of the material in order to obtain certain surface properties. In addition, it is sometimes desirable to modify the volumetric chemical composition and / or volumetric structure of the material in order to obtain certain volumetric properties.

Substrates including hair and skin are interesting in terms of modifying the surface and / or volume. The substrates are repeatedly subjected to mechanical washing, chemical treatments and environmental conditions, among which there are many factors that can lead to the loss of the desired properties of the substrates, such as natural and synthetically created shine, shine and structure. In addition, environmental factors can be added to these effects and, in essence, contribute to weathering or damage to the substrates. Severe damage to the surface of substrates, including hair and skin, can increase over time, leading to chronic damage.

Accordingly, there is a need for compositions and compensation methods for such things as the loss of the F-layer and the stratum corneum of hair and skin fibers, respectively, which provide long-term conditioning and protective effect. Covalent modification of the surface properties of damaged substrate materials is one example of this approach. There is also a need to protect, restore and / or strengthen these materials. Modifying the surface of a material by locally forming an active material on the surface of a material by reacting one or more active components to create covalent bonds between one or more active components and modifying the volume of the material by forming the active material in a similar manner in the bulk of the material are promising approaches.

SUMMARY OF THE INVENTION

A method of treating a substrate, comprising the steps of: applying the previously described composition to a substrate and applying the substrate treated with the composition to the action of scattered light. Alternatively, this method can be performed in several stages, the method comprising the steps of: applying at least one active material to the substrate, the active material containing one or more functional groups, and the substrate containing one or more complementary functional groups applying at least one photocatalyst capable of generating an acid or base by the action of light on a substrate; and a stage in which the photocatalyst and at least one active material are exposed to light. In any of the methods used, the action of light leads to the formation of covalent bonds between one or more functional groups of at least one active material and substrate.

One object of the compositions and methods described herein is to modify the surface and / or bulk properties of the substrate by covalently attaching the active material to the surface of the substrate. Another object of the compositions and methods described herein is to modify the surface and / or bulk properties of a substrate by treating the substrate with active compounds capable of reacting with each other to form covalent bonds between two or more molecules of the active compounds, thereby forming a secondary active material. Another other object of the compositions and methods described in this application is to ensure the functionalization of the surface of the substrate by covalently attaching the active material to the surface of the substrate. In order to achieve effective processing, it is sometimes desirable at the initial stage to attach to the substrate an active material that contains many similar functional groups in its molecule, followed by another stage of attaching another active material / effective agent by reaction to the initially attached active material. This is especially useful if the substrate contains only a limited density of functional groups that are capable of reacting with the active material / effective agent to form a chemical bond. For example, the initial addition of malic acid (2-hydroxy-1,4-dibutanoic acid) to the substrate increases the reactivity of the substrate by multiplying the two directional subsequent addition of the active substance. This is another another object of the compositions and methods described in this application, to provide, to some extent, such a modification / functionalization that is easily subject to sanitary and hygienic instructions and safety instructions, and which can be easily implemented in the field of personal care products and / or consumer care products.

Various embodiments relate generally to compositions and methods for treating a substrate. As used in this application, the term “substrate” means any material for which surface and / or volume treatment of such material is useful with the compositions and methods described herein. The terms “substrate” and “material” can be used interchangeably in the context of substances for modification by the compositions and methods described in this application. In addition, physiological materials include, but are not limited to, physiological materials, such as, for example, hair, skin, nails, gums and teeth.

Substrates may also include surfaces that have been previously modified, such as, for example, coated surfaces (e.g., varnished or painted) or laminated surfaces. The terms “substrate” and “material” can be used interchangeably in the context of substances to modify the compositions and methods described in this application. In various embodiments, the compositions described herein include an active component that can modify a substrate in the presence of an acid or base, a photocatalyst capable of generating an acid or base under the influence of light, and an acceptable carrier, which optionally may be a physiologically acceptable carrier. In various embodiments, the compositions described herein may also include one or more optional components, including surfactants, emulsifiers, oxidizing agents, reducing agents, pH adjusters, emollients, humectants, proteins, peptides, amino acids, polymer and copolymer additives , glossing agents, essential oils and / or fatty acids, lubricants, binders / chelating agents, antistatic agents, rheology modifiers, sensitive agents, fillers, preservative s, perfumes, other functional components, or combinations thereof.

In various embodiments, the methods described herein comprise treating a substrate by forming one or more covalent bonds between the active material and / or the substrate, wherein the covalent bond is formed in the presence of an acid or base generated by the photocatalyst under the action of light. In various embodiments, the methods described herein comprise treating a substrate by forming one or more covalent bonds between two or more active molecules of a component, wherein the covalent bond is formed in the presence of an acid or base generated by the photocatalyst under the influence of light, and the active material is on the surface and / or in the volume of the substrate. As used in this application, the term "molecule" means a fairly stable group of at least two atoms in a certain order fixed together by chemical bonds. Accordingly, the term “molecule” includes, but is not limited to, neutral molecular compounds, polyatomic ions, radical groups, biomolecules, monomers, dimers, trimmers, oligomers, polymer or copolymers, etc. In various embodiments, the methods described herein comprise treating the substrate “by preparing and covalently attaching the active material to the substrate, or by forming covalent bonds between the active materials on the surface of the substrate or in the bulk of the substrate, in situ, by providing the substrate, providing one or more reagents, providing the photocatalyst and giving the photocatalyst to the action of light in the presence of a substrate and one or more reagents, while the photocatalyst generates acid or base the formation, acid or base catalyzes a reaction between one or more reactants and / or a reaction between one or more reactants and a substrate, and covalent bonds are formed as a result of reaction (s). In various embodiments, the methods described herein include providing a system, including a substrate, an active material that can modify the substrate in the presence of an acid or a base, and a photocatalyst capable of generating acid or a base under the influence of light, giving the system exposure to light.

In general, difficulties are often experienced in order to achieve covalent attachment of active materials to substrates, such as, for example, hair or skin. This is especially difficult in the presence of water, which can quickly decompose reactive fragments before the functionalization of the substrate. Moreover, as is known, an aqueous medium chemically promotes the occurrence of hydrolysis and oxidation reactions, which can compete with the covalent addition of active materials to substrates. This can be a particular problem, for example, in consumer care products, where water is often used as a physiologically acceptable carrier. Consumer care products also often use water in various qualities, most of all as a solvent.

In addition, substrates, such as, for example, hair, skin, fabric, glass and ceramics, may not contain especially reactive chemical functional groups on the surface that would readily react with active components to form covalent bonds. This relatively low reactivity of the surface of the substrate can lead to a reaction system that is external, with a practical use-and-rinse environment (for example, shampooed and conditioner hair, soaped skin, washable fabrics or hard surfaces that can be cleaned) . Moreover, stringent regulatory requirements regarding product safety and environmental protection increase the requirements for providing compositions and methods for treating a substrate, such as, for example, hair, skin, fabric, glass or ceramic, by covalently coupling the active components.

However, various embodiments of the compositions and methods described herein are directed to photocatalytic technology that allows the use of light to activate a reaction, such as, for example, covalently coupling an active component to a substrate or forming covalent bonds between two or more active components in situ on the surface or in the bulk of the substrate material. Various embodiments can be used, for example, to activate covalent attachment of long-chain alkyl groups to damaged hydrophilic hair and / or skin in order to replenish and / or strengthen the normal hydrophobic property of these substrates. In addition, various implementations can be used, for example, to activate the covalent attachment of active materials to tissues or hard surfaces. Moreover, various embodiments can be used, for example, to place polymer or copolymerized monomers on the surface and / or in the bulk of the materials of the substrates in order to modify the surface and / or bulk properties of the material.

In various implementations, covalent attachment can bring many significant advantages. For example, fibers, such as hair or fabrics, can experience significant benefits, including, among others, improved touchability, reduced abrasion, easier handling, such as weaving, weaving, combing / combing, reducing dryness, improving smoothness, reducing curls, increased gloss, reduced static electricity, increased protection against damage due to other mechanical, chemical and environmental factors. For physiological substrates, such as skin, defining benefits may include, among others, reduced dryness, reduced redness, reduced itching, reduced peeling, and improved texture and smoothness. At least some of these advantages can be conveyed by the increase or targeted precipitation of the active substances obtained by surface modification through covalent attachment. For non-physiological substrates that are hard surfaces, such as glass or ceramic tiles, benefits may include reduced water stains, increased gloss or gloss, and easier subsequent cleaning. The benefits provided by the compositions and methods described herein are potentially longer lasting because an unstable covalent bond is used, which is generally stronger and more stable than absorption, adsorption, hydrogen bonding, ionic bonding, other electrostatic interactions and / or other transient non-covalent bindings used in previously used conditioners to precipitate or apply active ingredients to hair and / or skin. This can substantially reduce the frequency of use and reuse encountered when using known air conditioners.

Various embodiments of the compositions and methods described herein provide for covalent attachment of active materials to substrates, which may be described as, for example, an approach to repair and / or strengthen the F-layer of hair or skin of the stratum corneum. In the context of fibers, including, but not limited to, or otherwise limited by theory, the F-layer of non-treatable hair can be removed from the hair fibers in processes mediated by various mechanical, chemical, and / or environmental factors, as illustrated in FIG. .one. These processes may include, for example, oxidative and hydrolytic reactions, which are usually encountered in the processes of permanent hair coloring and permanent curling.

Figure 1 is a schematic diagram that illustrates FCSM of a hair fiber containing a portion of a keratinized epicuticle covalently linked to 18-MEA by forming thioether bonds between the carboxyl group of 18-MEA and the thiol group of cysteine residues in the keratin protein of the epicuticle. Hydrolytic and / or oxidative processes (for example, as a result of combinations of hydrogen peroxide, ammonia and high pH, which are usually encountered in the processes of permanent hair coloring and permanent curling), as well as other mechanical, chemical and environmental factors can remove at least at least part of the F-layer, breaking the cysteine-lipid thioether bond, leaving an exposed epicuticle that contains sulfonate groups on cysteine residues.

Anionic sulfonate groups on cysteine residues on the surface of the epicuticle change the surface state of any damaged hair fibers to hydrophilic, which as a result can give unwanted properties to damaged hair. Moreover, it is observed that more hydrophilic (and therefore more damaged) hair fibers reduce the deposition of active substances of previously used hydrophobic conditioners (such as, for example, dimethylsiloxanes, fatty alcohols and acids and Quaternary amines), due to non-covalent interactions and bonds. Accordingly, the compositions and methods described in this application provide an attractive approach to the processing of such damaged substrates.

Figure 2 schematically illustrates one non-limiting implementation of the compositions and methods described in this application for processing substrates. A composition comprising an active component having a hydroxyl group (R-OH) and a photocatalyst capable of generating an acid or base by the action of light in the presence of a substrate containing surface sulfonate and carboxyl groups is provided. The photocatalyst is amenable to the action of light, which causes the formation of an acid or base by the photocatalyst. An acid or base catalyzes the formation of a covalent ester bond between the hydroxyl group of the active material and the carboxyl group of the substrate.

Figure 3 and Figure 3A, which are considered together, schematically illustrates one non-limiting implementation of the compositions and methods described in this application for processing substrates. The part of the hair fiber containing the lipid layer (F-layer) and the protein layer (epicuticle) is shown. The protein layer contains structural proteins, such as, for example, keratin having disulfide bonds between cysteine residues. Hair can be treated with a reducing agent to break disulfide bonds to form the corresponding thiol groups. The hair can be further treated with an active component that contains one or more compounds capable of reaction to form covalent bonds between one or more compounds of the active component and / or between one or more compounds of the active component and thiol groups. The hair fiber is also treated with a photocatalyst. One or more active components and the photocatalyst penetrate the surface of the hair fiber substrate. A hair fiber substrate treated with one or more active components and a photocatalyst is exposed to light of an acceptable wavelength to activate the photocatalyst and catalyze the reaction between one or more active components in the hair fiber substrate and thiol groups.

In various embodiments, the active materials may be one or more monomers capable of polymerizing or copolymerizing in the presence of an acid or base. The fibers are treated with a composition comprising a photocatalyst and monomers of the active material that at least partially penetrate the fiber. Under the influence of light, the photocatalyst is activated, thereby generating an acid or base that catalyzes the monomers of the active material to polymerize or copolymerize the monomers, thereby forming a polymer or copolymer of the active material in situ, which optionally can attach to the fiber by forming covalent bonds between thiol groups and the polymer or copolymer.

In other implementations (not shown), these polymers or copolymers of the active material are non-covalently attached to the fiber. For example, a polymer or copolymer formed in situ can be physically immobilized on the surface of the hair fiber or in the pores of the hair fiber. The polymer or copolymer formed in situ may also be associated with the hair fiber by physical and / or chemical interaction, such as, for example, adsorption, absorption, electrostatic interaction, frictional interaction, steric interaction, and / or surface exclusion effects and / or in the volume of the substrate.

In various embodiments, the monomers of the active material may be styrene or a styrene derivative, such as, for example, α-methylstyrene. The monomer may also contain a mixture of different monomers, such that in situ upon polymerization or copolymerization (on the surface and / or in the bulk of the substrate) a polymer or copolymer is obtained.

Figure 4 schematically illustrates one non-limiting implementation of the compositions and methods described in this application for processing substrates. A composition is provided that contains an active material having a carboxyl group and a photocatalyst capable of generating an acid or base by the action of light in the presence of a substrate containing surface hydroxyl groups. The photocatalyst is exposed to light, which causes the formation of an acid or base by the photocatalyst. An acid or base catalyzes the formation of a covalent ester bond between the hydroxyl group of the substrate and the carboxyl group of the active material.

Therefore, photocatalysis of the reactions of formation of ester and / or ester covalent bonds between active components and substrates in various embodiments of the compositions and methods described in this application provides an effective, controlled, stable and physiologically acceptable approach to the processing of the substrate, such as, for example, restoration and / or strengthening the F-layer and the stratum corneum of the hair and skin, respectively.

Figure 5 presents a schematic representation of one non-limiting implementation of the mechanism for using the compositions and methods described herein in the context of a photonic acid catalyst. In a first step, a reagent solution is provided that includes a reagent, which may be an active component, and a photoacid catalyst. The reagent solution may contain shampoo, conditioner, another personal care product or consumer care product. In a second step, a reagent solution is applied to a substrate, which may be, for example, skin, hair, tissue, or a hard surface. The components of the reagent solution are deposited on the surface of the substrate. In a third step, a system containing a reagent solution and a substrate is exposed to light. Light causes deprotonation of the photocatalyst. In the fourth stage, between the reagent and the surface of the substrate, a photoacid-catalyzed esterification reaction occurs. In the fifth stage, the unreacted catalyst, reagent and protons are scattered from the surface of the substrate and removed from the system. In a sixth step, the modified / functionalized substrate is dried. In a seventh step, the modified / functionalized substrate is washed and rinsed. The modified / functionalized substrate essentially retains the covalently bound reagent after washing and rinsing.

Figure 6 presents a schematic representation of one non-limiting implementation of the compositions and methods described in this application. A porous substrate material 10 is provided. The substrate material 10 includes a substrate surface 15 and a bulk portion 20 having pores 25. The substrate material 10 is treated with a composition containing active material 30 and photocatalyst 35. Active material 30 may contain molecules capable of reacting together in the presence of acid or bases to form a secondary compound. For example, the active material 30 may contain one or more types of monomer capable of reacting to form a polymer or copolymer in the presence of an acid or base. The active material 30 and the photocatalyst 35 penetrate at least partially into the surface 15 of the substrate 10 in the bulk 20 through the pores 25. The substrate 10 is exposed to light of an acceptable wavelength to activate the photocatalyst 35, which generates an acid or base to catalyze the reaction of the active material 30 on the surface 15 and / or in the bulk part 20. At this time, the active material catalyzes and binds the substrate, the other active material forms a secondary active material from two or more active components in situ catalyzed composition. This secondary active material 40 is attached to the surface 15 and / or in the bulk portion 20 of the material of the substrate 10. The secondary active material 40 may contain, for example, polymers, copolymers, or combinations thereof. The secondary active material 40 can form a polymer network 45, which can modify the surface and / or bulk properties of the material of the substrate 10.

The secondary active material formed in accordance with the photocatalized acid or base mechanism described in this application may be on the surface and / or in the bulk of the substrate material. In various implementations, the location may be the result of covalent attachment of the secondary active material to the substrate material. In other implementations, the location may be the result of non-covalent chemical or physical interactions between the secondary active material and the surface and / or volume of the substrate material. For example, FIG. 6 illustrates a secondary active material containing a polymer network that is fixed to the surface and partially in the volume of the substrate material due to the physical formation of the polymer in the pores located in the material. In other implementations (not shown in FIG. 6), the secondary active material formed in accordance with the photocatalyzed acid or base mechanism described in this application may be on the surface of the substrate and / or in the volume of the substrate due to interactions such as adsorption, absorption electrostatic interaction, frictional interaction, steric interaction and / or dimensional exclusion effects. This allows you to control various properties of the material, such as, for example, the porosity of the processed substrate.

In various implementations, the active material and / or secondary active material formed in accordance with the photocatalyzed acid or base mechanism described in this application may be on the surface of the substrate and / or in the volume of the substrate due to changes in the properties of these materials when between molecules form covalent bonds. For example, when the active material contains a monomer / polymer system, the active material may be polymerized and / or cross-linked on the surface of the substrate. Polymerization and / or crosslinking may alter the solubility of the active material in the reaction medium, which may contribute to the deposition of the secondary active material on the surface of the substrate. In this method, the surface layer of the secondary active material can form on the surface of the substrate, thereby modifying the surface properties. This can result in the encapsulation of constituent fibers in fibrous substrates, such as, for example, hair and tissues. In various embodiments (not shown in FIG. 6), photocatalysis with an acid or base converts the active material, thus covalently binding it to a substrate (on the surface and / or in bulk), as described herein.

The compositions and methods described herein facilitate in situ and localized modification of material properties in a controlled manner. The active components covalently change (for example, by the formation of covalent bonds between them to form a secondary active material and / or between the active components and the substrate material) in a photoacid or photobasic reaction system.

The substrate for modification may be treated by spraying, soaking, spreading, coating, rinsing or any other suitable means of introducing the composition onto the surface of the substrate or into the bulk of the material of the substrate. In various embodiments, it is important to provide the entire surface of the substrate that is wetted with the reagent solution in order to provide sufficient modification of the surface and / or volume of the substrate. If the active material is at least partially insoluble in the carrier, it is important to maximize the contact between the active material and the substrate, for example, by minimizing the droplet size or particle size of the active substance in the carrier. In various implementations, it may be desirable to introduce a reagent solution into only one part or many parts of the surface of the substrate. In other implementations, it may be desirable to irradiate only one part or many parts of the surface of the substrate with light with a wavelength acceptable to activate the photocatalyst. Covalent modification occurs only on those areas of the substrate surface (and in the volume lying under them) that came into contact with the reagent solution and were irradiated with light with a wavelength acceptable for activating the photocatalyst. This allows you to control the location and extent of the surface and / or volumetric modification.

The acidic or basic photocatalytic mechanisms of covalent modification / functionalization described in this application may also be reversible. For example, substrate surfaces covalently modified or functionalized through esterification and / or thioesterification reactions may be contacted with an acidic aqueous solution of a surfactant. Alternatively, an alkaline surfactant solution may be used. These solutions can promote hydrolytic cleavage of the ester and / or ester bonds linking the active components to the substrate, thereby removing the active components.

This ability to remove is limited to activate the component-substrate bonds, which are reversible under appropriate conditions. For example, in the case of photo-acid catalyzed esterification, an ester bond is formed when the reactant and catalyst are present in the vicinity of the substrate and are exposed to the corresponding light. The high concentration of protons at the time of irradiation leads to the formation of ester bonds that remain intact because the generated protons easily propagate in the bulk of the medium. The low content of photonic acid allows subsequent stability and is close to a neutral pH of the volume of the aqueous solution. Under these conditions, the ester bond can be hydrolyzed at a very low rate. However, treatment with aqueous solutions with a sufficiently lower (or sufficiently high) pH will more likely break the ester bonds, leading to the initial unmodified surface of the substrate.

Removal of the covalently attached active substance can also be achieved by treating the modified or functionalized substrate with a composition comprising a photocatalyst (photonic acid or photobasis). This allows you to improve control over the time of removal of the active component from the substrate. This can be achieved if the photocatalyst is selected in such a way that it is not influenced by ambient light, but can generate acidic or based radicals under the influence of light of a certain wavelength, which the corresponding device provides.

Each of the various components of the compositions and corresponding methods described in this application, as well as preferred and optional components, is described in detail.

The active material in accordance with the present invention contains branched, cyclic, cross-linked and combinations thereof silicone polymers, copolymers and combinations of polymers and copolymer having a molecular weight of at least 150 gram / mol, alternatively 1000 gram / mol, from 3000 gram / mol to 10 million grams / mol, from 10,000 grams / mol to 7 million grams / mol, or from 50,000 grams / mol to 4 million grams / mol; and at least one organic functional group (and in one embodiment, many groups), including, but not limited to, hydroxyl, amino, carboxyl, sulfonate, thiol, epoxy, ester groups and / or any combination thereof, and Hi) level and the nature of substitution and the molecular weight of the silicone polymer or copolymer can be appropriately selected depending on the desired modification of the substrate and the conditions of use. For example, if increased hydrophobicity is desired, then less than 2% of the silicon atoms in the silicone polymer, copolymer, and combination of polymer and copolymer may be substituted with organic groups. The silicone polymer or copolymer may be from monomers that contain organic alcohol groups (primary and secondary), including those that have the structure:

R ₁ - [Si (CH- ₂ ) (R ₃ -CH ₂ OH) -O] _n - [Si (CH ₂ ) ₂ -O] _m -R ₂ ,

where R ₁ , R ₂ represent methyl; R ₃ represents CH ₂ CH ₂ CH ₂ - (OCH ₂ CH ₂ O) _q —H, where q≥1.

For example, hair modification can be achieved by treating the damaged hair with a silicone polymer and / or copolymer active material. Treatment with such an active material in an emulsion, dispersion and / or solutions with a photic acid generator, such as 8-hydroxyquinoline, can provide long-term benefits to damaged hair, for example, which are stable after repeated shampooing cycles. Examples of long-term benefits include soft hair (wet and dry), compatibility, no curls, ability to maintain shape and color, moisture and shine.

A method of surface modification involves the formation of covalent bonds between a silicone polymer or copolymer and a substrate. The bonds are created by the acid-catalyzed reaction of a primary or secondary alcohol of a polymer or copolymer with compatible functional groups of the hair substrate (for example, carboxylic acid groups relative to condensation).

Suitable silicone polymers and copolymers include those having an alkoxyalkanol group. In one embodiment, the silicone polymer and / or copolymer is bis-hydroxyethoxypropyl dimethicone, which has the structure:

Suitable bis-hydroxyethoxypropyl dimethicones include, but are not limited to, materials available such as 5562 Carbinol Fluid from Dow Coming and Baysilone OF OH 702 E from Momentive.

Photocatalyst

The photocatalyst can be any acid, base (or a combination thereof), with a pK _a (or pK _b ) value that decreases or increases under the influence of light. Light can be light of any acceptable wavelength, which results in a corresponding decrease or increase in pK _a or pK _b . For example, the light source may be ambient light, sunlight, light from an incandescent lamp, fluorescent light, light from an LED, laser light, etc. The composition in accordance with the present invention consumes light of the electromagnetic spectrum in the range from infrared to visible and ultraviolet light with a wavelength of from about 1200 nm to about 200 nm.

The use of UV against visible light (VIS) is not mutually exclusive, since many photoactive materials have a wide absorption spectrum that covers both. Separately, several examples show that chemical reactions achieved by UV light can be measurably enhanced by VIS. In fact, it is necessary to take into account the spectrum of action of the whole reaction in order to determine which wavelengths make significant contributions to the result. For a person skilled in the art, it is obvious that the corresponding wavelength or wavelengths will depend on the characteristics of one or more photocatalysts used.

In addition, acceptable light can be provided by any source capable of illuminating the surface of the substrate. For example, diffused sunlight, light from an incandescent lamp, fluorescent light, etc. can provide light of acceptable wavelength. Thus, the light can be provided by conventional sources such as lamps and portable or battery powered light sources. In addition, special devices can be created or adapted for use with the compositions and method described in this application. For example, a hair brush configured to include LEDs that provide light of an acceptable wavelength can be used to covalently modify the surface of the fibers. In various implementations, the laser can be used, for example, in order to ensure accurate determination of objects of covalent modification of the surfaces of the substrate.

In certain implementations, the photocatalyst is 8-hydroxyquinoline, which can act as a photic acid catalyst at lower pH values of the solutions or as a photobasic catalyst at higher pH values of the solutions. In certain other embodiments, the photocatalyst is the 8-hydroxy-1,3,6-pyrenesulfonic acid trisodium salt (D&C Green 8). In various embodiments, the photocatalyst is a photobase. Photobasic catalysts may include derivatives of tertiary alcohols, such as, for example, malachite green. Photobasic catalysts may also include derivatives of acridines, such as, for example, 9-hydroxy-10-methyl-9-phenyl-9,10-dihydroacridine. Photobasic catalysts may also include photoactive carbamate-containing compounds.

The photocatalyst may be present in the compositions and methods described herein in an amount of from 0,00050 percent to 30 percent by weight relative to the total weight of the composition. Basically, there is a preferred concentration of the photocatalyst. The preferred concentration of the photocatalyst depends, in part, on a variety of factors, including, for example, the chemical structure of the catalyst, the reaction medium, the type of reaction, and the substrate.

Carrier

The compositions described herein generally include a carrier acceptable for dispersing or dissolving the active material, photocatalyst and any other components to facilitate the application of the active material on the surface of the substrate or in part of the volume of the substrate. The carrier may contain one or more solvents, an emulsifier, a surfactant, or another dispersant. The properties of an acceptable carrier depend, at least in part, on the properties of the other components of the composition and substrate that modify. For example, when it is intended to use a composition for application to physiological tissues, a carrier for such a composition is selected so that it does not destabilize the composition, and also to avoid creating problems, such as irritation or damage to the target physiological tissue, as well as non-targeted surrounding tissues.

An acceptable carrier acts to disperse or dissolve the active material, photocatalyst and any other components, and to facilitate the application of the active material to the surface of the substrate. An acceptable carrier promotes sufficient contact between the active material and the substrate. In one embodiment, the physiologically acceptable carrier may be any carrier, solvent, or solvent-containing composition that is suitable for application to physiological tissues such as human hair and human skin.

As indicated previously, an acceptable carrier may be a solvent. For example, water is usually considered a beneficial solvent in consumer care products, including personal care products. In various consumer care products, including those in the present invention, water can be used at levels from 1% to 98% by weight of the composition. Water is especially useful for personal care products, as it does not cause damage to physiological tissues. An additional solvent or solvent-containing carriers include, but are not limited to, hydroxyl-containing liquids (e.g. alcohols), silicones, oils, hydrocarbons, glycols, ammonium lauryl sulfate, sodium lauryl sulfate, and combinations thereof. In certain embodiments, for example, in which the active material is at least partially insoluble in water, other solvents, dispersants, or emulsifiers can be used as acceptable carriers, alone or in combination with each other and / or with water.

An acceptable carrier is therefore usually used to dilute and / or emulsify the components that make up the compositions described herein. A suitable carrier may dissolve the component (true solution or micelle solution) or the component may be dispersed throughout the carrier (suspension, dispersion or emulsion). The carrier of a suspension, dispersion or emulsion is usually their continuous phase. That is, other components of the suspension, dispersion or emulsion are distributed at the molecular level or as discrete particles or agglomerates throughout the carrier. The preparation of such emulsions or dispersions of the active substance, in these cases, can be extremely important. Small particles contribute to close contact between the active substance, the substrate and the photoacid catalyst, increasing the reaction rate. For example, if a fiber surface is modified using fatty alcohol and 8-hydroxyquinoline in an aqueous medium, an emulsion that contains very small particles (e.g., less than 500 nanometers, or more preferably less than 200 nanometers) can be substantially more effective in providing long-term hydrophobic surface than an emulsion containing large particles.

For a person skilled in the art, it is obvious that the respective carrier (s) depend on the characteristics of the active (s) material (s), photocatalyst (s) and other (optional) component (s) used in compositions described in this application.

Optional components

The compositions and methods described herein may optionally include many components. For example, in various embodiments, the compositions and methods described herein may include surfactants, emulsifiers, oxidizing agents, reducing agents, pH adjusters, emollients, humectants, proteins, peptides, amino acids, polymeric or copolymer additives, agents for imparting gloss, oils, and / or fatty acids, lubricants, binders / chelators, antistatic agents, rheology modifiers, sensitive agents, fillers, dyes, pigments, preservatives, perfumes, medicines nts, other functional components, or combinations thereof. Details of optional components can be found in the CTFA International Cosmetic Ingredient Dictionary, Tenth Edition, 2004; and in McCutcheon, Detergents and Emulsiflers, North American Edition (1986). It will be apparent to those skilled in the art that the optional components that are especially used will depend, at least in part, on the particular applications for the compositions and methods.

In various embodiments, the compositions and methods described herein include an oxidizing agent (oxidizing agent). An oxidizing agent may be added, for example, to make the surface of the substrate more photocatalytic covalent modification / functionalization in accordance with the various implementations described in this application. The oxidizing agent may be present in an amount of from 0,00050% to 25%, from 0.1% to 10%, from 0.5% to 5% by weight relative to the total weight of the composition. Suitable oxidizing agents include, for example, one or more of hydrogen peroxide, urea peroxide, melamine peroxide, percarbonates, peroxides, alkali metal bromates, perborates, bromates, hypochlorites, chlorites, perchlorates, iodates, periodates, permanganates and persulphates. In certain embodiments, the oxidizing agent is hydrogen peroxide.

The identity of the reaction system, the amounts and concentrations of the reagents used, and the reaction conditions completely depend, at least in part, on the substrate to be modified, the active material used and the method by which the active material is bound to the substrate. These considerations are obvious to a person skilled in the art when performing the compositions and methods described in this application.
