    BACKGROUND OF THE INVENTION
    [0001]. Shampoo and hair conditioner formulas, when applied separately, produce less than desired results for the user. For example, after applying the shampoo, the hair may become too dry. After applying the conditioner, the hair may become excessively conditioned.
    [0002]. Shampoo formulas often contain surfactants, such as sodium lauryl sulfate, sodium lauryl ether sulfate and ammonium lauryl ether sulfate. These sulfate-based surfactants facilitate the cleaning process because they decrease the surface tension of the water and, thus, allow the water to bind to the dirt in the hair. However, sulfate-based surfactants tend to leave hair very dry and, therefore, consumers prefer to use sulfate-free surfactants as a shampoo. There is a need to offer consumers shampoo products without sulfate-based surfactants.
    [0003]. Hair conditioners contain polydimethylsiloxanes, commonly known as silicone, as part of their formula. These silicone-based hair conditioning agents, such as dimethicone and cyclodimethicone, have become popular as hair conditioners because they are convenient for making hair look full, shiny, soft and easy to comb. However, when used for a long time, silicone-based conditioning agents form a layer on the hair, thus preventing it from obtaining sufficient hydration. Therefore, despite the effects on the appearance of making the hair look full and shiny, conditioning formulas with silicone-based conditioning agents raise concerns among consumers.
    [0004]. Even when shampoo and conditioner formulas are applied at the same time in a mixture, the problems noted above may not be mitigated. For example, classic 2 in 1 shampoo formulas add a silicone-based conditioner and suspending agent to a sulphate-based shampoo. However, these 2 in 1 formulas would not yet solve the problem because, as part of the shampoo-conditioner mixture, the shampoo prevents the conditioner from properly conditioning a fraction of the hair, while the conditioner prevents the shampoo from properly cleaning another fraction of the hair. In addition, the components in many of these 2 in 1 formulas contain sulfate-based surfactants and silicone-based conditioning agents.
    [0005]. Therefore, there is still a need for a composition for hair cleaning and conditioning that offers a balance between cleaning and conditioning properties and, at the same time, is free of sulfate-based surfactants and silicone-based hair conditioning agents.

    [00028]. In the following sections, certain compounds are additionally identified by names in accordance with the International Nomenclature of Cosmetic Ingredients (INCI) system. DETAILED DESCRIPTION OF THE INVENTION
    [00029]. One embodiment of the invention consists of a composition for cleaning and conditioning hair essentially free of sulfate-based surfactants and silicone-based conditioning agents. The composition includes at least one anionic surfactant, at least one cationic hair conditioning agent and a thickening polymer capable of thickening and stabilizing the composition.
    [00030]. The term "hair cleaning", as used in this document, means washing your hair with shampoo and water, in order to remove dirt and oily materials. Capillary cleansing agents are surfactant molecules that will be treated more thoroughly later on.
    [00031]. The term “hair conditioning”, as used in this document, means treating the hair with agents that give it at least one property selected from ease of combing, manageability, maintaining hydration, luster, shine and smoothness. Hair conditioning agents will be treated further below.
    [00032]. "Hair conditioning" is usually done after "hair cleaning". In this document, in accordance with the present invention, "hair conditioning" takes place together with "hair cleaning".
    [00033]. The term "at least one", as used in this document, means one or more and therefore includes individual components, as well as mixtures or combinations.
    [00034]. The terms "essentially free of sulfate-based surfactants" and "essentially free of sulfate" refer to the content of sulfate-based surfactants in the composition of the present invention. "Essentially free of sulphate-based surfactants" means that, while it is preferable that no sulphate-based surfactants are present in the composition, it is possible to have very small amounts of sulphate-based surfactants in the composition of the invention, as long as those amounts do not. materially affect the advantageous properties of the composition. In particular, "essentially free of sulfate-based surfactants" means that sulfate-based surfactants can be present in the composition in an amount less than about 2.0% by weight, typically less than about 1.5% by weight. weight, typically less than about 1.0% by weight, typically less than about 0.5% by weight, typically less than about 0.1% by weight and, more typically, 0% by weight, based on in the total weight of the composition.
    [00035]. The term "sulfate-based surfactant", as used in this document, also means "sulfate-containing surfactant". Therefore, the term "essentially free of sulfate-based surfactants" also means "essentially free of surfactants containing sulfate".
    [00036]. The terms "essentially free of silicone-based hair conditioning agents" and "essentially silicone-free" refer to the content of silicone-based hair conditioning agent in the composition of the present invention. “Essentially free of silicone-based hair conditioning agents” means that, although it is preferable that no silicone-based hair conditioning agents are present in the composition, it is possible to have very small amounts of silicone-based hair conditioning agents in the composition. composition of the invention, provided these amounts do not materially affect the advantageous properties of the composition. In particular, “essentially free of silicone-based hair conditioning agents” means that a silicone-based hair conditioning agent can be present in the composition in an amount less than about 2.0% by weight, typically less than about 1.5% by weight, typically less than about 1.0% by weight, typically less than about 0.5% by weight, typically less than about 0.1% by weight, and more typically, 0% by weight, based on the total weight of the composition.
    [00037]. The term "silicone based hair conditioning agent" as used in this document also means "silicone containing hair conditioning agent". Therefore, the term “essentially free of silicone-based hair conditioning agents” also means “essentially free of silicone-containing hair conditioning agents”.
    [00038]. The term "stabilize the composition" means that the formula derived from the composition maintains its initial appearance and specifications at various temperatures for a specific period of time.
    [00039]. Hair cleaning agents in shampoo formulas are surfactant molecules with a polar end and a supporting end. The polar end of the surfactant molecule is hydrophilic because it attracts water molecules, while the support end of the surfactant molecule is hydrophobic because it repels water molecules. In sufficient quantities in an aqueous environment, the surfactant molecules organize themselves to form spherical structures called micelles, so that the polar ends are on the outer surface (that is, facing the water) while the supporting ends are on the inside. Surfactants improve hair cleaning because they connect the supporting ends of the surfactant molecules to oily materials in the hair and keep them inside the micelles. Effectively, oily materials are fragmented by the apolar ends of the surfactant molecules and stored inside the micelles, while the polar ends of the surfactant molecules keep the micelles soluble in water.
    [00040]. Surfactants can be anionic (negatively charged), cationic (positively charged), nonionic (uncharged) or amphoteric (simultaneously negative and positive). Examples of anionic surfactants include sulfates, sulfonates, phosphites, phosphates, phosphonates and the like. Examples of cationic surfactants include alkyl ammonium salts, quaternary ammonium salts and the like. Examples of nonionic surfactants include alkoxylated alcohols, alkoxylated phenols, fatty acid esters, derivatives of amine, derivatives of amide and the like. Examples of amphoteric surfactants include derivatives of propionic amino acid, derivatives of imion propionic acid, betaines, sulfobetaines and the like.
    [00041]. Conventional hair cleansing agents contain surfactants, such as sodium lauryl sulfate, sodium lauryl ether sulfate, ammonium lauryl sulfate and ammonium lauryl ether sulfate. These sulfate-based surfactants are effective as hair cleansing surfactants because they efficiently remove oily particles from the hair. However, sulphate-based surfactants are less desirable because consumers find them less bland.
    [00042]. According to one embodiment of the invention, at least one anionic surfactant is essentially free of sulfate-based surfactants and is a member selected from the group consisting of isethionate, taurate, sarcosinate, sulfosuccionate, sulfoacetate, glycate, glutamate and carboxylate, in which at least one anionic surfactant has an alkyl chain from Cs to C20 and a solubilizing counter-cation selected from sodium, potassium and ammonium. Preferably, at least one anionic surfactant is essentially free of sulfate-based surfactants and is a member selected from taurate and isethionate, where at least one anionic surfactant has an alkyl chain from Cs to C20 and a selected solubilizing counter-cation among sodium, potassium and ammonium.
    [00043]. According to one embodiment of the invention, the capillary cleaning and conditioning composition comprises at least one anionic surfactant essentially free of sulfate-based surfactants. At least one anionic surfactant may be a member selected from the group consisting of sodium methyl cocoyl taurate, sodium cocoyl isethionate, sodium lauryl methyl isethionate and sodium methyl oleyl taurate.
    [00044]. The composition can also include two or more anionic surfactants essentially free of sulfate-based surfactants. The anionic surfactants can be two members selected from the group consisting of sodium methyl cocoyl taurate, sodium cocoyl isethionate, sodium lauryl methyl isethionate and sodium methyl oleyl taurate.
    [00045]. According to one embodiment, anionic surfactants suitable for the composition are sodium methyl cocoyl taurate and sodium cocoyl isethionate. Methyl cocoyl sodium taurate offers high soapy power, high foam stabilizing effect, good cleaning properties and smoothness. Sodium cocoyl isethionate also exhibits similar cleaning, soaping and foaming properties.
    [00046]. According to another embodiment of the invention, other anionic surfactants can be adopted to be cleaning agents, including sodium lauryl methyl isethionate, sodium cocoyl glutamate and sodium methyl oleyl taurate. In addition, a nonionic surfactant, such as decyl glycoside, can be used in addition to taurates and isethionates as part of the composition for hair cleaning and conditioning.
    [00047]. According to one embodiment, the anionic surfactant ranges from about 0.1% to about 16.0% by weight, preferably from about 0.5% to about 14.0% by weight and, more preferably , from about 1.0% to about 12.0% by weight, based on the total weight of the composition.
    [00048]. According to one embodiment, the anionic surfactants are taurate and isethionate, where the taurate ranges from about 0.1% to about 8.0% by weight and the isethionate ranges from about 0.1% to about 8 , 0% by weight, based on the total weight of the total composition.
    [00049]. Preferably, with respect to the amounts of anionic surfactants in the composition of the present invention, the taurate ranges from about 0.5% to about 7.0% by weight and the isethionate ranges from about 0.5% to about 7.0% by weight, based on the total weight of the total composition.
    [00050]. More preferably, with respect to the amounts of anionic surfactants in the composition of the present invention, the taurate ranges from about 1.0% to about 6.0% by weight and the isethionate ranges from about 1.0% to about 6.0% by weight, based on the total weight of the total composition.
    [00051]. Hair conditioning agents protect the hair by forming a coating on the outer layer of the hair strand called the cuticle. Conditioning agents reproduce the function of sebum, the natural conditioner that is produced and secreted by the sebaceous gland of the hair follicle. Tallow, which is a mixture of wax monoesters, triglycerides, fatty acids and squalene, binds to keratin, the hair protein. As keratin is usually anionic (negatively charged), cationic conditioning agents (positively charged) do well in connection with keratin.
    [00052]. Hair conditioners can be categorized for the purposes they are intended to obtain for the consumer, such as moisturizing conditioners, conditioners with proteins or conditioners with reduced static electricity. In the case of dry, wavy and curly hair, moisturizing conditioners that use alcohols, silicones and essential oils are useful. In the case of hair that needs to appear fuller, conditioners with proteins that help to coat the hair shaft are useful. In the case of tangled and iridescent hair due to scales on the cuticle layer of the hair strand, conditioners with reduced static electricity help to smooth the scales on the hair strand and thus allow each hair to be separate and malleable.
    [00053]. Silicone-based hair conditioners have become popular because they tend to make hair look full and pliable to the consumer. Silicone-based hair conditioners give hair a uniform silky feel, shine, hydration and superior styling benefits. However, when used for a long time, silicone-based hair conditioners tend to attract dirt, which reduces the shine and good looks of the hair as a whole. Silicone-based hair conditioning agents also tend to accumulate with prolonged use, which weighs the hair down and can leave an unpleasant residue on the hair fibers. Therefore, depending on the consumer's preference, silicone-based conditioning agents may be less desirable.
    [00054]. According to one embodiment of the invention, the hair cleaning and conditioning composition also includes at least one cationic hair conditioning agent essentially free of silicone based hair conditioning agents. The composition may also include two or more cationic hair conditioning agents essentially free of silicone based hair conditioning agents. Cationic hair conditioning agents suitable for the composition of the invention include polyquaternium-10 (also called quaternized polyhydroxy ethyl cellulose) and cetrimonium chloride (also called trimethyl ammonium cetyl chloride, CTAC). Polyquaternium-10 is a multifunctional cationic polymer that improves compatibility with moisture and contributes to a full appearance. Cetrimonium chloride, being positively charged, binds well to the keratin protein in the hair and thus helps to prevent the development of static electricity.
    [00055]. According to another embodiment of the invention, the capillary cleaning and conditioning composition includes other cationic hair conditioning agents, such as berrenthrimone chloride (also known as docosyl trimethyl ammonium chloride), berrentrimonium methane sulfate, steartrimony chloride , stearalkonium chloride and dichethyldimony chloride.
    [00056]. In addition, at least one cationic conditioning agent can be an amphoteric conditioning agent capable of carrying a pH-based cationic charge or an amphoteric conditioning agent that remains amphoteric and imparts conditioning attributes to the hair. Examples of amphoteric conditioning agents include: polyquaternium-22, polyquaternium-39, polyquaternium-47 and polyquaternium-53.
    [00057]. According to one embodiment, the composition further comprises at least one amphoteric conditioning agent selected from the group consisting of polyquaternium-22, polyquaternium-39, polyquaternium-47 and polyquaternium-53.
    [00058]. According to one embodiment of the invention, at least one cationic conditioning agent of the composition can be combined with at least one amphoteric conditioning agent in a mixture. The use of at least one amphoteric conditioning agent as part of a combination with at least one cationic conditioning agent results in compositions that demonstrate different attributes.
    [00059]. Other conditioning agents that can work in conjunction with the cationic conditioning agents listed above include, but are not limited to, four different types: (A) amphoteric conditioning agents, (B) cationic conditioning agents, (C) non-ionic conditioning agents and (D) agents anionic conditioners.

    [00067]. According to one embodiment of the invention, the cationic conditioning agents are polyquaternium-10 and cetrimonium chloride.

The various components of the composition of the present invention can be selected accordingly: anionic surfactants are sodium methyl taurate and sodium cocoyl isethionate, the cationic conditioning agents are polyquaternium-10 and cetrimonium chloride, and the acrylate-based polymer capable of thicken and stabilize the composition is a cross polymer of C30 to C30 acrylates / alkyl acrylates.
    [00078]. According to one embodiment, at least one anionic surfactant ranges from about 0.1% to about 16% by weight, at least one cationic hair conditioning agent ranges from about 0.05% to about 7.0% by weight, and the acrylate-based polymer ranges from 0.05% to about 2.0% by weight, where the weight percentages are based on the total weight of the composition.
    [00079]. According to one embodiment, the composition comprises sodium methyl cocoyl taurate in the range of about 0.1% to about 8.0% by weight, sodium cocoyl isethionate in the range of about 0.1% to about 8.0% by weight, polyquaternium-10 in the range of about 0.05% to about 2.0% by weight, cetrimonium chloride in the range of about 0.1% to about 5.0% in weight and cross polymer of acrylates / C10 to C30 alkyl acrylate in the range of about 0.05% to about 2.0% by weight. All weight percentages above are based on the total weight of the composition.
    [00080]. The composition according to the invention produces several favorable characteristics, including maintenance of the foam structure, foam stability and foam formation, while at the same time achieving cleaning and conditioning properties. The composition offers a very unique balance between cleanliness and conditioning. Anionic surfactants essentially free of sulfate-based surfactants according to the composition are capable of cleaning the hair of the sebum, stylizing the product accumulation. In addition, cationic hair conditioners essentially free of silicone based conditioning agents are able to form a deposit on the surface of the capillary cuticle, resulting in uniform and conditioned hair. The composition demonstrated excellent cosmetic properties, such as curl definition and superior frizz control without weighing the hair, which is a very desirable attribute that consumers prefer. As a result, consumption according to the invention meets the objective of hair cleaning along with the objective of hair conditioning.
    [00081]. In the composition of the present invention, the combination of anionic surfactants, such as sodium methyl cocoyl taurate and sodium cocoyl isethionate, with cationic hair conditioning agents, such as polyquaternium-10 (“PQ-10”) and trimethyl ammonium cetyl chloride (“ CTAC ”), cleans the hair and, at the same time, leaves it conditioned and uniform. In addition, the composition has unique flow properties thanks to the presence of the acrylate-based polymer and the anionic surfactant cocoyl sodium isethionate, thus providing good foaming attributes. In addition, the acrylate-based polymer also stabilizes and optimizes the surfactant system. According to the invention, the preferred hair cleaning and conditioning composition has the consistency of a lotion, which allows for easy distribution throughout the hair and contributes to a quick foam and easy detangling.
    [00082]. In some embodiments of the present invention, the anionic surfactant sodium lauryl methyl isethionate can be used instead of sodium cocoyl isethionate. In addition, cationic conditioners berrentrimony chloride (docosyl trimethyl ammonium chloride) and / or berrentrimonium methosulfate can replace cetrimonium chloride. In other cases, any combination of polyquaternium-10, cetrimonium chloride, berrenthrimony chloride and berrenthrimone methosulfate can be used for the present invention, resulting in different foam properties.
    [00083]. According to another embodiment, a composition for hair cleaning and conditioning comprises: sodium methyl cocoyl taurate, sodium cocoyl isethionate, polyquaternium-10, cetrimony chloride and a C30 to C30 acrylate / alkyl acrylate cross polymer, wherein composition is essentially free of sulfate-based surfactant and silicone-based hair conditioning agents, sodium methyl cocoyl taurate ranges from about 0.1% to about 8.0% by weight, sodium cocoyl isethionate ranges from about 0.1% to about 8.0% by weight, polyquaternium-10 ranges from about 0.05% to about 2.0% by weight, cetrimonium chloride ranges from about 0, 1% to about 5.0% by weight and the C30 to C30 acrylates / alkyl acrylate cross polymer ranges from about 0.05% to about 2.0% by weight, with the weight percentages based on the total weight of the composition.
    [00084]. According to another embodiment of the invention, a hair cleaning and conditioning method includes the steps of (a) providing a hair cleaning and conditioning composition with at least one anionic surfactant, at least one cationic hair conditioning agent and a polymer based acrylate capable of thickening and stabilizing the composition, so that the composition is essentially free of sulfate-based surfactants and silicone-based hair conditioning agents; (b) applying the makeup to a user's hair; and (c) rinse the treated hair with sufficient water.
