Bamboo extract, strengthening of hair strength, hairstyle persistence

Description

[0001] The present invention relates to a hair styling composition containing bamboo extract,

The present invention relates to a purifier composition, and more particularly, to a purifier composition that contains bamboo extract to enhance the strength of hair and enhance hair style persistence.

In general, the main function of the hair is as follows. The hair protects the human body from the mechanical and chemical stimuli of the extraterrestrial. That is, it prevents the intrusion of harmful substances and protects the human body from external stimuli such as cold, friction, danger, and direct sunlight. Second, it has a cosmetic effect that decorates the appearance with decorative function. This is an important role that characterizes women and men. Third, it acts to transmit tactile sensation or pain by the sensory function.

The importance of hair in terms of cosmetic effect, which is decorative function, has been emphasized from ancient times. Recently, with the emergence of perms, dyeing, and the like, the hair has become more popular as a means of expression of personality. However, in recent years, due to the frequent chemical treatment and the daily use of the hair dryer using the heat, the hair of the modern people has suffered a lot of damage and the frequent interruption of the mid-break has been a problem.

On the other hand, a cosmetic composition used for temporarily shaping a hair style and continuing the style is a composition for a regular composition, and examples thereof include a hair spray, a mousse, a gel, and a wax. These properties of the stabilizer composition should be such that the desired hair shape can be maintained for a long period of time, that it is useful when there is no stickiness, that it can be easily cleaned, and that the hair has proper gloss and softness And so on.

Examples of the method for fixing and setting the hair of such a cleanser composition include a method using a semi-solid or viscous oil at room temperature, a method using a polymer resin, and a method using a moisturizer. The most commonly used setting agent is a polymer resin type, in which a polymer such as pyrrolidone, acrylic acid, or acrylate is used alone or in the form of a copolymer thereof. This film attaches to the hair and forms a fixing force to the hair to make a desired style. However, the film thus formed has a disadvantage in that the fixing property at the hair is deteriorated over time because the inherent film characteristics are lost at high temperature and high humidity.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a cleanser composition that contains bamboo extract to improve the strength of hair to prevent breakage and improve hair style sustainability.

In order to achieve the above object, the present invention provides a detergent composition containing a bamboo extract.

The composition comprises a setting agent and a solvent which is water or ethanol, and contains 0.1 to 20% by weight of bamboo extract and 0.1 to 30% by weight of a setting agent based on the total weight of the composition.

The present composition contains a bamboo extract, thereby enhancing the strength of the hair to prevent breakage of the hair, which often occurs when a style is produced. In addition, it enhances the sustainability of the hairstyle to maintain the desired hairstyle for a long time.

The present invention contains a bamboo extract, which contains a setting agent and a residual amount of water or ethanol.

In the present invention, bamboo extract means obtained from various organs or parts (for example, leaves, flowers, roots, stems, branches, etc.) of bamboo, and preferably refers to extracts obtained from stems and leaves.

The bamboo extracts of the present invention can be prepared according to conventional methods known in the art, that is, under the conditions of ordinary temperature and pressure, using conventional solvents.

The bamboo extract, which is an active ingredient of the composition of the present invention, can be dissolved in a solvent selected from the group consisting of water, an anhydrous or lower alcohol having 1 to 4 carbon atoms, acetone, ethyl acetate, butyl acetate, propylene glycol, and 1,3- Is preferably used alone or in combination. It is more preferable to use water and propylene glycol mixture for extraction, and the mixing ratio of propylene glycol to water in the mixture may be 0.3 to 1.3 times as much as water, , And more preferably 0.4 to 1.0 times. A suitable amount of the extraction solvent is 10 to 150 times, more preferably 15 to 100 times, the bamboo dry weight.

According to a specific embodiment of the present invention, the extraction process is carried out as follows. First, the raw bamboo is washed, dried and crushed into small pieces. Then, a mixture of water and propylene glycol is added at a ratio of 30 times the dry weight of bamboo, and the mixture is put into an extractor equipped with a cooling condenser. Then, the mixture is allowed to stand at 15 to 35 ° C for 5 days, aged, filtered, and dried in a vacuum evaporator to obtain a bamboo extract.

On the other hand, the bamboo extract of the present invention includes not only the extract obtained by the above-mentioned extraction method, but also the extract obtained through ordinary purification process.
