Description

Hair Mist Cosmetic Composition

The present invention relates to a hair cosmetic composition for strengthening the surface and the inside of the hair, in particular, while containing a similar ceramide to restore the cuticle and coltex of damaged hair, while maintaining the formulation stable, long-term storage is possible, Provided are hair cosmetic compositions for hair surface and internal strengthening that can be prepared in a convenient formulation.

Hair is composed of medula, cortex, and cuticles, and most of the hair is cortex composed of keratin proteins.

If the cortex's keratin protein is lost, the hair weakens with symptoms such as hair loosening and hair breakage. To prevent the loss of the cortex's keratin protein, it is necessary to protect and improve the hair cuticle of the hair.

The hair cuticle is a thin layer in the outermost layer of hair that is layered to protect the cortex's keratin proteins.

It is necessary to protect and improve the hair cuticle to protect keratin proteins in the cortex from external stimuli such as perma, dyeing, and dryer, and at the same time manage them as smooth and shiny hair.

Ceramide is an constituent of intercellular lipids, which is also present in the hair cuticle, and plays a similar role in hair protection.

In addition, it penetrates to the cortex of the hair and fills the part lost due to damage, thereby increasing the strength and elasticity of the hair.

Attempts have been made to provide a hair cosmetic composition comprising a ceramide component to protect the cuticle of the hair and to strengthen the hair cortex.

Although the importance of ceramide is widely known and many cosmetic companies have researched to develop hair cosmetics using it, ceramide is a very difficult ingredient to obtain in nature. The development of ceramide is under way.

Looking at the ceramides currently applied to products in Korea, the ceramides extracted from microorganisms (natural ceramide III), pseudoceramide PC-104 developed by famous P company (International Publication No. WO2014-084676), and similar ceramide PC-9S of N company (USA Patent US6221371) and the like, but there is a disadvantage that is difficult to dissolve in the composition for structural reasons.

Recently developed pseudo-ceramide PC-AKS (International Patent Publication No. WO2016-076520) has greatly improved the dissolving ability to be used relatively freely in hair cosmetic compositions, but further studies on solubilization due to unstable low temperature stability when developing into an oil formulation. It is necessary and there is a need to improve performance and usability.

An object of the present invention for solving the above problems is to increase the adsorption power to the surface of the hair through improving the dissolving power of the similar ceramide, to maintain a stable in the composition, while providing a convenient formulation, while providing a hair cuticle protection and improvement effect At the same time to provide a hair cosmetic composition that can give a good feeling.

In order to achieve the object of the present invention, the present invention, a) pseudo ceramide of Formula 1; b) branched hydrocarbons of C _8-16 carbon atoms as volatile oils c) higher fatty alcohols of C _16-20 carbon atoms; d) an alcohol having _{1 to 10} carbon atoms; and 0.001 to 1% by weight of the pseudo ceramide, based on the total weight of the hair cosmetic composition; 40 to 80% by weight of branched hydrocarbons as the volatile oil; Higher fatty alcohol is 10 to 40% by weight and 5 to 20% by weight of the alcohol; Included,

It provides a hair cosmetic composition, characterized in that the weight ratio of b) component and c) component is 1: 1 to 3: 1.

[Formula 1]

_Branched hydrocarbons having _{8 to 16} carbon atoms as the volatile oil are used for the purpose of trimming the hair together with pseudoceramides, preventing static electricity, and providing shine, and are 40 wt% to 80 wt% with respect to the total weight of the composition. It is preferable to include, less than 40% by weight does not have a hair trimming effect, if the content exceeds 80% by weight has a disadvantage in that the feeling is greatly damaged.

The volatile oil may be a volatile hydrocarbon oil or a silicone oil.

For the purposes of the present invention, the term "volatile oil" means an oil capable of evaporating in less than one hour at room temperature and atmospheric pressure (760 mmHg) when in contact with keratin materials.

The volatile organic solvent (s) and volatile oils of the invention have a non-zero vapor pressure at room temperature and atmospheric pressure (760 mmHg), in particular in the range from 0.13 Pa to 40,000 Pa (10 ^-3 to 300 mmHg), in particular 1.3 Pa to 13 000 Volatile organic solvents or cosmetic oils that are liquid at room temperature, having a vapor pressure in the range of Pa (0.01 to 100 mmHg), more particularly in the range of 1.3 Pa to 1300 Pa (0.01 to 10 mmHg).

The oil may be a hydrocarbon-based oil, a silicone oil or a fluoro oil, or a mixture thereof.

In particular, volatile oils which may be mentioned are volatile hydrocarbon-based oils, in particular volatile hydrocarbon-based oils having a flash point of 80 ° C. or less (flash points are measured in particular according to ISO standard 3679), for example hydrocarbons containing 8 to 14 carbon atoms. System oils, in particular, include:

Branched C8-C14 alkanes such as C8-C14 isoalkanes of petroleum origin (also known as isoparaffins) such as isododecane (also known as 2,2,4,4,6-pentamethylheptane), Isodecane and oils sold for example under the trade names Isopar or Permethyl,

Linear alkanes such as n-dodecane (C12) and n-tetradecane (C14) sold by Sasol under the reference Parafol 12-97 and Parafol 14-97, respectively, and also mixtures thereof, undecane-tridecane Mixtures, mixtures of n-undecane (C11) and n-tridecane (C13) obtained in Examples 1 and 2 of patent application WO2008 / 155 059 by Cognis, and mixtures thereof.

The volatile solvent is preferably selected from volatile hydrocarbon oils and mixtures thereof containing from 8 to 14 carbon atoms.

As other volatile hydrocarbon oils, in particular, volatile hydrocarbon oils having a flash point of 80 ° C. or lower include ketones which are liquid at room temperature, such as methyl ethyl ketone or acetone; Short-chain esters (comprising 3 to 8 carbon atoms in total), such as ethyl acetate, methyl acetate, propyl acetate or n-butyl acetate; Ethers that are liquid at room temperature, such as diethyl ether, dimethyl ether or dichlorodiethyl ether; Mention may be made of alcohols, in particular linear or branched lower monoalcohols comprising 2 to 5 carbon atoms, such as ethanol, isopropanol or n-propanol.

A volatile hydrocarbon oil having a flash point above 80 ° C. is isohexadecane.

Preferred volatile oils in the present invention include volatile hydrocarbon oils, among them, isododecane and isohexadecane.

As the volatile oil, a branched hydrocarbon having _{8 to 8} carbon atoms may be selected and used according to the purpose of the hair cosmetic. These may be used individually by 1 type and may use 2 or more types together.

The higher fatty alcohol is used for the solubilization of ceramide, preferably 10 to 40% by weight based on the total weight of the composition. If less than 10% by weight, similar ceramides are precipitated at a low temperature, and if more than 40% by weight, the hairs aggregate and reduce the trimming effect.

Higher fatty alcohols usable in the present invention are isocetyl alcohol, isostearyl alcohol, isostearyl alcohol, chimyl alcohol, C16-17 isoalcohol, hexyldecanol, octyl Dodecanol (Octyldodecanol), butyloctanol (Butyloctanol) and cetyl arachidol (Cetylarachidol) is characterized in that at least one member selected from the group consisting of.

The alcohol imparts a refreshing feeling to the hair and helps to improve the stability of the dissolved pseudo-ceramide, and it is preferably included in an amount of 5% to 20% by weight based on the total weight of the composition, and less than 5% by weight If this is insufficient, and if it exceeds 20% by weight, the compatibility with the oil is lowered and the formulation becomes unstable. Among the alcohols, ethanol is preferably used.

In the present invention, as the volatile oil, C _8-16 branched hydrocarbon and the higher fatty alcohol are preferably used in a weight ratio of 1: 1 to 3: 1. If the branched hydrocarbon is included as a relatively small amount out of the range as compared to the higher fatty alcohols as the volatile oil, the hair is agglomerated and the trimming effect is lowered, and if it is included in a relatively large amount, the similar ceramide is not stabilized and precipitated, which is not preferable.

According to one embodiment of the present invention, the hair cosmetic composition is excellent in formulation stability, and can be formulated into a convenient formulation, and may be composed of a mist type and a serum type.

In the present invention, the hair surface strengthening hair cosmetic composition may further comprise 1% by weight or more of the fragrance.
