Description

Non-aqueous wax-type hair cosmetic composition

The present invention relates to a non-aqueous wax-type hair cosmetic composition, and more particularly, to a hair cosmetic composition having no hairiness, as well as providing a glossiness to the hair and phase change to a liquid phase upon application.

Humans have a desire to keep their hair in various forms, and have attempted permanent and temporary deformation of the hair. Methods of permanently modifying hair include using chemical raw materials that react with the hair to achieve the desired effect, and as the technology advances, the raw materials and methods used are diversified. As a result, the extent of hair damage is increasing, and the desire to protect and care for hair is also increasing.

Products used to protect the hair include wash-off emulsion products (rinses, treatments, etc.) and rib-on types of creams, lotions and essences. In particular, the rib-on type of products that do not need to be washed are easy to use and can be applied from time to time. However, these products are emulsion-type or carbomer-containing products, most of which contain a large amount of water (see US Pat. Nos. 4,938,954 and 5,993,832), and therefore the content of oils and silicones is limited. In addition, in the case of a cosmetic composition consisting only of an oily raw material, most of the stickiness is very high and there is a disadvantage that it is not easy to apply to the palm or hair.

Therefore, the technical problem to be achieved by the present invention is to increase the content of oil or silicone, while maximizing the hair protection effect, evenly applied to the hair by having a feature that is transferred from the solid phase to the liquid phase during use, non-sticky wax type hair excellent in feeling because it is less sticky It is to provide a cosmetic composition.

Another technical problem to be achieved by the present invention is to provide a styling composition containing a film forming agent for setting having the above-described effect.

In order to achieve the above technical problem, the present invention is 40 to 70% by weight of cyclomethicone; 1 to 10 weight percent polyethylene; 1 to 20 weight percent wax; 0.1 to 10 weight percent oil; 1 to 20% by weight of polymerized silicone; And it provides a non-aqueous wax-type hair cosmetic composition comprising 1 to 10% by weight of silicone powder.

Hereinafter, the non-aqueous wax-type hair cosmetic composition of the present invention will be described in more detail.

The present invention 40 to 70% by weight of cyclomethicone; 1 to 10 weight percent polyethylene; 1 to 20 weight percent wax; 0.1 to 10 weight percent oil; 1 to 20% by weight of polymerized silicone; And it provides a non-aqueous wax-type hair cosmetic composition comprising 1 to 10% by weight of silicone powder.

The hair cosmetic composition of the present invention includes cyclomethicone which is a volatile silicone oil. Such cyclomethicone is not only excellent in skin stability, but also imparts a light, non-sticky feeling in the non-aqueous composition that may be heavy. Such cyclomethicones include DC 245, 344, 345, 246, etc. of Dow Corning Corporation, but the present invention is not limited thereto.

 The content of such cyclomethicone is preferably 40 to 70% by weight based on the total weight of the total cosmetic composition in consideration of water repellency, anti-sticking effect in use, and stability of the formulation. Use of cyclomethicone in excess of this range can lead to poor stability, such as shrinkage of the formulation over time.

The hair cosmetic composition of this invention contains polyethylene. Such polyethylene serves to maintain the formulation by increasing the oil phase in the cosmetic composition of the present invention. Polyethylene used in cosmetics is used in a variety of molecular weights ranging from 450 to 2000. However, when the polyethylene molecular weight is more than 600, since the melting point is more than 100 ℃ Celsius, there is a disadvantage in that it is difficult to commercialize industrially. Therefore, it is preferable that the polyethylene used for this invention is 450-550 in molecular weight.

The content of the polyethylene is preferably 1 to 10% by weight based on the total weight of the cosmetic composition, the use of this content of polyethylene, to increase the wax, oil, silicone oil, etc. to keep the formulation stable in the solid wax form Can be. If the content of polyethylene is less than 1% by weight, the formulation is not hardened and it is difficult to stabilize the formulation, such as silicone oil coming off. If the polyethylene content is more than 10% by weight it becomes too hard to show a disadvantage that it does not get on your hands when using.

Hair cosmetic composition of the present invention comprises a wax to maintain the final properties in a solid phase, the content is preferably 1 to 20% by weight relative to the total weight of the cosmetic composition. When the wax is less than 1% by weight, it is difficult to maintain the composition in the solid phase, and when the wax is more than 20% by weight, the wax does not show the characteristic of being transferred to the liquid phase in use.

As such wax components, ceresin wax, candelilla wax, microcrystalline wax, cowvana wax, beeswax wax, higher alcohol having a degree of polymerization of 20 or more, etc. may be used alone or in combination. Among the waxes, ceresin wax that exhibits an ideal phase transition phenomenon as a hair cosmetic composition is more preferable, and such ceresin wax and other waxes may be mixed and used.

The cosmetic composition of this invention contains an oil. As such oils, hydrocarbon-based oils such as squalane, liquid paraffin, and vegetable oils such as macadamia nut oil and olive oil may be used, but the present invention is not limited thereto.

The content of such oil is preferably 0.1 to 10% by weight relative to the total weight of the cosmetic composition when considering the feeling of use. On the basis of this range, there is a disadvantage that the hardness of the composition may be weakened when an excess oil is used.

The cosmetic composition of the present invention can basically keep the hair soft and smooth, and in order to impart this function, the cosmetic composition of the present invention includes high-polymerization silicone. In general, in the case of a formulation containing water, it is difficult to use a large amount of high-polymerization silicone such as high-polymerization dimethicone, but the cosmetic composition of the present invention has a molecular weight of about 300,000 to 50 million cs of 1 to 20% by weight of high-polymerization dimethicone Even when used, the formulation can be kept stable. As the high-polymerization silicon, high polymerization dimethicone, amodimethicone, etc. having a viscosity of 1,000 to 50,000,000 cs may be used alone or in combination, but is not limited thereto.

The cosmetic composition of the present invention contains a silicone powder to give a fresh and non-sticky feeling. As the silicone powder, any one or more selected from vinyl dimethicone / methicone silsesquioxane crosspolymer, dimethicone / vinyl dimethicone crosspolymer, polymethylsilsesquioxane, and the like may be used, and the content thereof may be used in the total amount of the cosmetic composition. It is preferable that it is 1-10 weight% with respect to weight, and it is preferable that the average particle size of silicone powder is 0.2-30um.

The cosmetic composition of the present invention is a component used as a styling agent capable of fixing or styling hair according to the purpose within the range that does not impair the above object of the present invention, a component that provides a moisturizing and conditioning effect, a thickener, Additives such as fragrances, sunscreens, hair protectors, pigments, etc. may comprise 0.5 to 10% by weight relative to the total weight of the cosmetic composition.

The cosmetic composition of the present invention may include a film forming agent for setting as the additive, and such a film forming agent for setting may include methacryloylethylbetaine / methacrylate copolymer, olylacrylamide / acrylate / butyl Aminoethyl methacrylate copolymer, polyvinylpyrrolidone, polyvinylpyrrolidone / vinylacetate copolymer, polyvinylpyrrolidone / dimethylaminoethylmethacrylate copolymer, acrylate methacrylate copolymer , Vinyl acetate / crotonate / vinyl neodecanoate copolymer may be used, but is not limited thereto.
