Description

Hair rinse composition {HAIR RINSE COMPOSITIONS}

The present invention relates to a hair rinsing composition capable of smooth and shiny, voluminous natural hair styling after washing hair, and specifically, an acrylate copolymerized with polymerizable vinyl monomers under a hydrocarbon solvent such as isopropyl myristate. The present invention relates to an O / W emulsion type hair rinse composition containing an acrylates / stearyl methacrylate copolymer and behentrimonium chloride.

There are two types of hair products. In other words, it is divided into products that wash off with water such as shampoo and rinse and products that give functions such as setting power to hair without leaving with water such as hair spray and gel.

Leave-on products, such as hairsprays and gels, use compositions of anionic, cationic, nonionic and zwitterionic resins to impart hair dressing function (Korean Patent Application No. 1995-7005775, 1996-7006729, 1996-7007333, 1997-0046601, 1997-0046601 and Republic of Korea Patent Registration 10-0470954). In these Leave-on hair products, anionic or zwitterionic resins, which are leading the setting function hair dressing agent in the composition, have the advantage of excellent hair setting ability because the film is coated on the hair and is not affected by humidity. There is a problem in that artificial hair styling that is hard and unnatural is produced. On the other hand, when the setting function hair dressing agent used in such a Leave-on hair product is used in a wash-off product composition such as a rinse, it is very sticky, or the setting function hair dressing agent does not adhere to the hair. Because they are washed off with water, they do not perform as a hair dresser.

In general, hair products that provide hair setting provide volumetric artificial styling without directly applying hair and then leaving it on. In this case, in order to provide a styling function, it is necessary to use a setting resin (Setting Polymer) in the hair product composition. Since the resin has a setting force by the adhesion of hairs to each other, it gives a non-natural, hard texture, and also has the property of being washed off with water because of its solubility in water.

Hair products that are washed off with water, such as hair rinses, are oils or silicones adsorbed on the hair to provide shine and softness. Hair products like these hair rinses are not capable of setting volumetric styling because of their softening function. People with thin hairs and few hairs have a strong desire for products that can create naturally voluminous hair styles to make hair look rich, but there are still technical limitations in addressing these needs. In order to overcome such technical limitations, in the prior art, the hair rinse composition contains a generally used setting resin commonly used, but in this case, there is a problem that it becomes sticky in the hair and hands together with a feeling of being stiff and smooth and soft. (Korean Patent Application 1993-7003761, 1996-7007540, 2002-0081729, 1997-709934, 1997-7009982, 1997-7009984).

The inventors of the present invention seek to develop products that provide abundant hair styling by giving a soft and natural volume after using hair rinse, and generally known (meth) acrylic copolymers or graft silicone polymers (Korean Patent Application 2002-0081729, 1997- 709934) were used as hair rinse compositions. In this case, however, most of the setting polymers were washed away when the hair rinse was applied to the hair and washed with water, and the setting power of the hair was so low that it did not provide the desired natural volume of hair styling. Increasing the content of the (meth) acrylic copolymer (Korean Patent Application 2002-0081729) composition in order to increase the setting effect of the hair rinse, there is a problem that the stickiness of the hand becomes very severe and reluctant to use it.

Accordingly, in the present invention, as the emulsion type (O / W) hair rinse composition, the behentrimonium chloride composition dispersed in an aqueous phase and the acrylic copolymer hair dresser dissolved in an oil phase are uniformly adsorbed to the hair at an optimum ratio. By coating, the object of the present invention is to provide a hair rinse composition which can provide a smooth and natural shine and setting power to the hair without stickiness.

Hair rinsing composition of the present invention for achieving the above object is 0.01 to 10% by weight of acrylate / stearyl methacrylate copolymer (Formula 1) and behentrimonium chloride (Behentrimonium Chloride) 0.01 to It comprises 10% by weight.

Wherein R ₁ is a hydrogen atom or a methyl group, R ₂ is a C ₁ -C ₄ alkyl group, R ₃ is a C ₁₂ -C ₁₈ alkyl group, X is a hydrogen atom, soap monomers are polyalkylene oxide and carbon atoms of 12-18 The polymerizable (meth) acrylate containing a long chain alkyl group is shown, l, m, and n are integers, respectively, and l + m + n is in the range of 50-98.

Here, the acrylate / stearyl methacrylate copolymer is a short-chain (meth) acrylate monomer having 1 to 4 carbon atoms, a long-chain (meth) acrylate monomer having 12 to 18 carbon atoms, and a functional monomer containing a carboxyl group in a hydrocarbon solvent. And a soap monomer (Soap Monomer) is copolymerized, 1 to 80 parts by weight of (meth) acrylate-based monomer units, 1 to 20 parts by weight of monomer units containing carboxyl groups, 0.1 to 5 parts by weight of monomer units containing soap monomers And it is preferable to copolymerize using 20-99 weight part of hydrocarbon solvents.

In addition, the acrylate / stearyl methacrylate copolymer has a short chain (meth) acrylate monomer having 1 to 4 carbon atoms, 20 to 70% by weight of the total polymerizable monomer, and a long chain (meth) acrylate monomer having 12 to 18 carbon atoms. 10 to 65% by weight of the total polymerizable monomer, 1 to 20% by weight of the functional monomer containing a carboxyl group, and 1 to 20% by weight of the soap monomer (Soap Monomer) desirable.

On the other hand, the hair rinse composition of the present invention may further comprise 0.01 to 20% by weight of dimethicone (Dimethicone), and also, PEG-5 Hydrogenated Castor Oil (PEG-40 Hydrogenated Castor Oil) 0.1 to 5% by weight, iso It is preferable to further include 0.1 to 10% by weight of propyl myristate and 0.1 to 10% by weight of cetearyl alcohol.

Hereinafter, the present invention will be described in detail.

The hair rinse composition of the present invention is in the form of an emulsifier (O / W Emulsion Type; O: Oil dispersed phase / oil phase, W: Water continuous phase / water phase), and an acrylate / stearyl methacryl which is a copolymerized acrylate hair dressing agent in the oil phase. Acrylates / Stearyl Methacrylate Copolymer is dissolved in a hydrocarbon solvent such as Isopropyl Myristate, and Behentrimonium Chloride and, in some cases, Dimethicone are dispersed in the aqueous phase. Is dissolved.

The hair rinse composition of the present invention is characterized in that beryltrimonium chloride (Acrylates / Stearyl Methacrylate Copolymer) in which polymerizable vinyl monomers are copolymerized under a hydrocarbon solvent such as isopropyl myristate. Behentrimonium Chloride). The acrylate / stearyl methacrylate copolymer is a novel acrylate-based hair dressing agent that has a good solubility in oil and excellent adhesion to hair, and has a function of sustaining natural hair setting power for a long time.

When the hair rinse composition of the present invention is applied to the hair, rinsed with water, and then drained with a towel, behentrimonium dispersed in an acrylate / stearyl methacrylate copolymer, an acrylate-based hair dressing agent dissolved in an oil phase, and dissolved in an aqueous phase Chloride and dimethicone are adsorptively coated on the hair surface at an optimum content ratio. The composition of the present invention has good application properties without stickiness when used on the hair, and if the hair is styled with a hot air balloon such as dry or curling iron after using the hair, the hair is naturally non-sticky and has a voluminous natural hair styling with a high setting (styling) effect. Not only is it possible to keep the hairstyle for a long time.

In the hair rinse composition of the present invention, the acrylate / stearyl methacrylate copolymer is a short-chain (meth) acrylate having 1 to 4 carbon atoms under a hydrocarbon solvent such as isopropyl myristate. Copolymerized acrylate system consisting of monomer, long chain (meth) acrylate monomer having 12 to 18 carbon atoms, functional monomer containing carboxyl group and soap monomer (Soap Monomer) (Formula 1), solubility in oil is very good. It has the property of excellent adhesion to hair and detergency to shampoo.

[Formula 1]

Wherein R ₁ is a hydrogen atom or a methyl group, R ₂ is a C ₁ -C ₄ alkyl group, R ₃ is a C ₁₂ -C ₁₈ alkyl group, X is a hydrogen atom, soap monomers are polyalkylene oxide and carbon atoms of 12-18 The polymerizable (meth) acrylate containing a long chain alkyl group is shown, l, m, and n are integers, respectively, and l + m + n is in the range of 50-98.

The first monomer in the structure of the acrylate / stearyl methacrylate copolymer composition, which is a copolymerized acrylate-based hair dressing agent, is a short-chain (meth) acrylate monomer having 1 to 4 carbon atoms as methyl (meth) acrylate and butyl (meth) acrylate. And isobutyl (meth) arcrelate and the like, and the amount of use is 20 to 70% by weight relative to the total polymerizable vinyl monomer. The polymerizable vinyl monomer is a monomer which may affect the glass transition temperature, which is a thermal property of the polymer, and has adhesion and fixation property to hair. Therefore, when the amount is less than 20% by weight, it is difficult to make the hair into a voluminous hairstyle, on the contrary, the rinse hairdressing composition containing more than 70% by weight is dried as a hard film, resulting in no natural hair setting power and agglomeration phenomenon. There is a problem that is difficult to remove during cleaning.

The second monomer is a long chain (meth) acrylate monomer having 12 to 18 carbon atoms, which may include lauryl (meth) acrylate, palmityl (meth) acrylate, stearyl (meth) acrylate, and the like. It is used in the range of 10 to 65% by weight based on the monomers. The polymerizable vinyl monomer has properties related to compatibility with hydrocarbon-based solvents in the composition of the styling product. Therefore, when it is less than the use range, the dissolving power can be lowered. On the contrary, the excess amount of the dried film of the resin composition has a problem in that the dissolving power in water is lowered and it is difficult to remove it during washing.

The third monomer is a functional monomer containing a carboxyl group, which may be used in combination of one or two types of acrylic acid, methacrylic acid, itaconic acid, and the like, and gives hydrophilicity of a rinse hairdressing agent to easily wash hair when washing hair. This makes it easier to remove the rinse hair dresser from the hair. The usage-amount of the functional monomer containing a carboxyl group is the minimum amount range for providing washability, and is 1-20 weight% with respect to all the polymerizable monomers, Preferably it is 1-10 weight%. Rinse hairdressing composition containing an excess of the functional monomer containing a carboxyl group has better solubility in water (aqueous) than oil, so that the hair rinse does not have a setting power function because the adhesive with hair is washed off during washing. There is a problem.

The fourth monomer is a soap monomer, and includes a polyethylene oxide and a stearyl group. As the polyalkylene oxide structure included in the soap monomer, ethylene oxide (EO) or propylene oxide (PO) may be used alone, or a structure (EPO) in which ethylene oxide and propylene oxide are mixed and blocked may be used. In particular, when ethylene oxide is used, water solubility is better than propylene oxide, and thus, when used as a detergent such as shampoo or rinse, it has an advantage of excellent water washing power. In particular, the water washing effect on the scalp or skin is excellent. It can be used in 1 to 20 weight% with respect to all the polymerizable monomers, Preferably it is 1 to 10 weight%.

In the hair rinse composition of the present invention, behentrimonium chloride (Behentrimonium Chloride) dispersed in an aqueous phase has a quaternary ammonium salt structure, and dimethicone is silicone having a structure in which linear siloxane polymer is completely methylated. Since the surface structure of the hair (cuticle layer) has negative charges, the behentrimonium chloride and dimethicone compositions having these cationic charge characteristics are highly adsorptive to the surface of the hair having anionic charge characteristics and have good coating power. Because of its excellent application, it gives your hair a natural glow and softness, giving it a healthy hair.

These Behentrimonium Chloride and Dimethicone have the following structural formula.

X is an integer here and exists in the range of 1-99.

In the hair rinse composition of the present invention, when only the acrylate / stearyl methacrylate copolymer composition dissolved in a hydrocarbon solvent is used without using behentrimonium chloride or dimethicone, a high setting (styling) effect gives a natural volume. The characteristics of making hair styling and keeping the hairstyle for a long time are very good, but not only the softness and gloss of the hair falls, but also the greasy feeling which the user generally does not mind. On the other hand, when only behentrimonium chloride or dimethicone is used without using an acrylate / stearyl methacrylate copolymer, the hair is fresh, soft and shiny without greasy feeling, but high for hair styling. It does not have a fixed effect, making it difficult to create voluminous and natural hair styling.

Hair rinsing composition of the present invention by using each of the components in the optimum content ratio to give the hair a non-sticky shine, soft and high setting (fixing force) effect to create a natural hair styling with a long time as well as a long time Has the ability to keep the hairstyle.

The composition of the present invention has good application properties without stickiness when used on the hair, and if the hair is styled with a hot air balloon such as dry or curling iron after using the hair, the hair is naturally non-sticky and has a voluminous natural hair styling with a high setting (styling) effect. Not only is it possible to keep the hairstyle for a long time.

As shown in Table 1, the hair rinse compositions of the examples prepared with the acrylate / stearyl methacrylate copolymer, behentrimonium chloride and dimethicone were associated with the softness, application and stickiness of the hair rinse products of the comparative example. Is similar, but the setting power to give a shine and natural volume is very high. In addition, as in Comparative Examples 2 and 3, when the PVP (polyvinylpyrrolidone) resin composition, which is a nonionic setting agent generally used in gels, is used in hair rinsing products, not only the setting power but also the softness and stickiness are generally reduced. It can be seen that the quality is poor.
