Water in Silicon emulsion type for hair cosmetic composition {Water in Silicon emulsion type for hair cosmetic composition}

The present invention relates to a water-in-silicone emulsified hair cosmetic composition comprising a silicone emulsifier, a nonionic polymer, a silicone oil and a silicone resin, and has excellent setting power, setting lasting power, agglomeration upon application, and glossiness to hair. do.

In general, the emulsified cosmetic composition is largely divided into an oil-in-water (O/W) emulsion type and a water-in-oil (W/O) emulsion type. The oil-in-water (O/W) emulsification type is a hydrophilic type, and although it feels moist and soft, it has the disadvantages of poor cosmetic durability and water resistance. A water-in-oil (W/O) emulsification type, which is a lipophilic type, has been developed to improve these drawbacks. However, the water-in-oil (W/O) emulsification type has very good cosmetic durability and water resistance, but has disadvantages in that it puts a burden on the skin due to stickiness and oiliness, and the feeling of use such as spreadability and spreadability is poor.

In particular, the conventional emulsion composition contains a large amount of hydrocarbon-based oils such as liquid paraffin and squalane, ester (including triglyceride) oils, and vegetable oils such as olive oil, cottonseeds, and macadamia oil. As it is known that there is, it does not satisfy consumers' desire for hypoallergenic cosmetics.

However, since silicone oil is very light due to its elastic and three-dimensional structure, it has excellent feeling of use such as malleability and spreadability and skin stability, as well as excellent water resistance and emollient effect. Development of a water-in-silicone (W/S) emulsified cosmetic composition using oil as a trauma is continuously being made.

Among silicone-in-water emulsified cosmetics, hair styling cosmetics are hairdressing products used for the purpose of making hair into a specific shape desired by the user and maintaining the setting effect. There are chemical methods and physical methods for making and maintaining hair in a desired shape. The chemical method is a semi-permanent setting method generally called 'perm' by changing the bonding position between cysteine residues in the protein constituting the hair. , the physical method is to temporarily fix the hair using a polymer compound such as resin or gum, and cosmetic formulations for temporary styling are usually prepared in the form of wax, gel, mousse, spray, or the like.

Compositions to which the conventional formulation is applied have excellent compatibility with various setting agent raw materials and provide excellent hair adhesion and setting power, but are not suitable for realizing and maintaining root volume due to heavy feeling after application. Also, there is a problem that natural resetting is difficult when you want to correct the curl shape. Therefore, the need to develop a styling product having a light feeling of use to realize and maintain root volume while having excellent setting power is continuously demanded by consumers.

An object of the present invention to solve the above problems is to provide a water-in-silicone (W/S) emulsified hair cosmetic composition having excellent volume lasting power by giving a feeling of use that is not heavy while having excellent root volume forming power and setting power of hair.

An aspect of the present invention in order to solve the above problems, silicone emulsifier 0.1 to 4% by weight; 1 to 20% by weight of a nonionic polymer; 2 to 10% by weight of silicone oil; and 0.1 to 2% by weight of silicone resin; It relates to a water-in-silicone (W/S) emulsified hair cosmetic composition comprising a.

The water-in-silicone (W/S) emulsified hair cosmetic composition according to the present invention exhibits excellent effects in hair setting power such as hair volume and styling.

In addition, the glossiness of the hair after drying and the feeling of stickiness of the styling agent when used are significantly reduced, so that the feeling of use is excellent.

Hereinafter, the present invention will be described in more detail.

The water-in-silicone (W/S) emulsified hair cosmetic composition of the present invention contains 0.1 to 4% by weight of a silicone emulsifier; 1 to 20% by weight of a nonionic polymer; 2 to 10% by weight of silicone oil; and 0.1 to 2% by weight of silicone resin; may include.

In one embodiment of the present invention, the water-in-silicone (W/S) emulsification type is a formulation in which silicone oil is emulsified while enveloping water, and due to its elastic and three-dimensional structure, it is very light and spreadability and skin stability. great.

The silicone emulsifier may be used without limitation among dimethicone copolyols, preferably PEG-10 Dimethicone Crosspolymer, PEG-10 Dimethicone/vinyldimethicone crosspolymer (PEG-10). Dimethicone/Vinyl Dimethicone Crosspolymer), Cetyl PEG/PPG-10/1 Dimethicone (Cetyl PEG/PPG-10/1 Dimethicone), PEG-10 Dimethicone, PEG-12 Dimethicone, Bis-PEG/ It may be at least one selected from PG-14/14 dimethicone and PG/PG-18/18 dimethicone.

The silicone emulsifier is preferably included in an amount of 0.1 to 4% by weight, more preferably 0.5 to 3% by weight based on the total weight of the hair cosmetic composition.

When the content of the silicone emulsifier is less than 0.1% by weight, formulation stability becomes poor, and when it exceeds 4% by weight, there is a problem in that the initial setting force is inferior.

The silicone emulsifier preferably has a Hydrophilic-Lipophilic Balance (HLB) of 1 to 10.

If the HLB is less than 1, it is difficult to prepare a W/S formulation, and if it exceeds 10, there is a problem in that formulation stability is poor. In addition, the viscosity of the silicone emulsifier is 100 to 50,000 cPs.

In one embodiment of the present invention, the nonionic polymer is preferably a vinylpyrrolidone (VP)-based polymer.

The vinylpyrrolidone (VP)-based polymer is at least one selected from polyvinylpyrrolidone (PVP), which is a homopolymer of vinylpyrrolidone, and a copolymer (copolymer) of vinylpyrrolidone and other nonionic polymers. or a mixture thereof, and the copolymer of vinylpyrrolidone and other nonionic polymers is selected from among vinylpyrrolidone/vinyl acetate copolymers and vinylpyrrolidone/methacrylamide/vinylimidazole copolymers. It may be one or more selected.

The polyvinylpyrrolidone (PVP) preferably has a K value of 30 to 100, more preferably 60 to 90. Specifically, Luviskol K30 (BASF Corp), K90 (BASF Corp), polyvinylpyrrolidone (PVP) K-30 (Ashland Inc), K-60 (Ashland Inc), K-90 (Ashland Inc) ), etc.

If the K value is less than 30, there is a fear that effects of hair setting power such as hair volume and styling may become insufficient, and if it exceeds 100, handling properties may deteriorate.

The K value is a viscosity characteristic value correlated with molecular weight, and can be calculated by applying the relative viscosity value (25° C.) measured by a capillary viscometer to Equation 1 of Fikentscher below.

<Equation 1>

K=(1.5logη _rel -1)/(0.15+0.003c)+(300clogη _rel +(c+1.5clogη _rel ) ² ) ^1/2 /(0.15c+0.003c ² )

η _rel : Relative viscosity of polyvinylpyrrolidone aqueous solution with respect to water

c: concentration of polyvinylpyrrolidone in polyvinylpyrrolidone aqueous solution

The copolymer of vinylpyrrolidone and other nonionic monomers is preferably at least one selected from a vinylpyrrolidone/vinyl acetate copolymer and a vinylpyrrolidone/methacrylamide/vinylimidazole copolymer, and A pyrrolidone/vinyl acetate copolymer is more preferable.

The vinylpyrrolidone/vinyl acetate copolymer has a molar ratio expressed as vinylpyrrolidone (VP) (mol)/vinyl acetate (VA) (mol), VP (mol) / VA (mol) = 50/50 to It is preferable that it is the range of 99/1, and it is more preferable that it is the range of 60/40 - 99/1.

The molar ratio is within the range in which the copolymer becomes completely water-soluble (1 g of the product is added to 1000 ml of water at 25 ° C., and completely dissolved if left for 30 minutes after penetration). Due to the odor of the prescription, the smell of the prescription becomes poor.

The nonionic polymer preferably has a weight average molecular weight of 10,000 to 3,000,000, and more preferably 50,000 to 1,500,000.

The content of the nonionic polymer is preferably included in an amount of 1 to 20% by weight, more preferably 5 to 15% by weight, based on the total weight of the hair cosmetic composition.

If the content of the nonionic polymer is less than 1% by weight, there is a fear that the setting effect will be insufficient, and if it exceeds 20% by weight, it hardens quickly when applied, making it difficult to direct natural styling.

The polyvinylpyrrolidone and vinylpyrrolidone/vinylacetate copolymer is a representative nonionic polymer that provides strong setting power in hair styling products, and the vinylpyrrolidone/methacrylamide/vinylimidazole copolymer is a vinyl Due to the rigid structure of pyrrolidone and vinylimidazole, high setting power and durability can be expressed, and soft coating properties can be expressed due to the flexible rise of methacrylamide in the middle.

The present invention may include silicone oil in order to impart a setting effect.

The silicone oil is preferably at least one selected from cyclopentasiloxane, methylpolysiloxane, methylphenylpolysiloxane, methylcyclopolysiloxane dimethicone, cyclomethicone, stearylmethicone, stearyldimethicone, caprylyldimethicone, and cetyldimethicone. and more preferably cyclopentasiloxane, and the cyclopentasiloxane is used as a silicone solvent in the W/S emulsion formulation.

The silicone oil is preferably included in an amount of 2 to 10% by weight, more preferably 3 to 8% by weight, based on the total weight of the hair cosmetic composition.

When the silicone oil content is included in less than 2% by weight, it is difficult to implement a W / S emulsion formulation, and when it exceeds 10% by weight, there is a fear that the setting effect may be insufficient.

In the present invention, a silicone resin may be included as a plasticizer in order to prevent flaking that may occur due to the use of the nonionic polymer.

The silicone resin is preferably at least one selected from polymethylsilsesquioxane and trimethylsiloxysilicate, or a mixture thereof.

The silicone resin is preferably included in an amount of 0.1 to 2% by weight, more preferably 0.5 to 1.0% by weight, based on the total weight of the hair cosmetic composition.

When the silicone resin is included in an amount of less than 0.1% by weight, it cannot exhibit performance as a plasticizer, and when it exceeds 2% by weight, the viscosity of the W/S formulation may be excessively increased.

The hair cosmetic composition of the present invention contains a styling agent, a moisturizer, a fragrance, a sunscreen, a conditioning agent, a hair protectant, a colorant, and a preservative that can fix or style hair according to the purpose within the scope that does not impair the above object of the present invention. , may further include one or more additives selected from antioxidants and vitamins.
