Description

Hair cosmetic composition for maintaining freshness and bracing durability on the scalp}

The present invention relates to a hair cosmetic composition that maintains freshness and freshness, and more specifically, to a hair by preparing an encapsulated powdery fragrance that can provide freshness and freshness to the scalp with a water-insoluble or poorly water-soluble coating. In the process of rinsing with water after washing, the speed of washing is slower than general synthetic or natural fragrances which are dissolved. As a result, the time for contacting the scalp is enhanced, and thus the powdered flavor capsules are prepared to have the effect of maintaining the freshness and freshness of the scalp. It relates to a hair cosmetic composition.

Generally, hair products such as shampoo, rinse and treatment are hair cosmetics used to remove the contamination of the scalp and hair and to keep the hair clean and beautiful.In addition to the purpose of cleaning, it is easy to comb, softness, smoothness and gloss. It is used for additional purposes such as imparting, lowering the friction of the hair surface, antistatic and protecting the hair. The purpose of blending the fragrance in such a hair cosmetic composition is to give the scalp a refreshing feeling and freshness, and for this purpose, a fragrance called menthol is used. However, the fragrances currently used are present in the form of solubilized by water and surfactant in the formulation, so that when the rinse starts to be used on the hair, it is quickly washed off, which makes it difficult to maintain the freshness and freshness as the initial use.

Recently, techniques for encapsulating them using various polymers have been developed to maintain the effects of various perfume ingredients. For example, Korean Laid-Open Patent Publication No. 2003-83161 discloses a hydrogel containing a microcapsule and a gelling agent containing a fragrance component and having a nasal congestion effect, and Korean Laid-Open Patent Publication No. 2005-31235 A spray type shampoo is disclosed that can be easily cleaned without the need for water washing and is not irritating to the skin.

In addition, US Patent Publication No. 2004-0087477 discloses a flavor capsule prepared by capturing a flavor component in an aminoplast including urea-formaldehyde or melamine-formaldehyde and a secondary polymer, and US Patent Publication No. 2004-0087477 -0072720 discloses polymer capsule flavors encapsulated inside polymer capsules in which the fragrance component is coated with a mixture of cationic polymers.

However, no research has been conducted on the process of encapsulating the fragrance or its use to maintain the freshness and freshness of the hair cleanser composition.

Accordingly, the present inventors encapsulate a powder fragrance having a relatively low solubility in water and surfactant with a water-insoluble or poorly water-soluble coating, and then blending it in a hair cosmetic composition so that the capsule is struck between the hair and the finger when used directly and rinsed with water. The powder fragrance adheres to the scalp and hair while being broken by the physical force of the back, so that the freshness and freshness can be sustained for a long time.

Accordingly, it is an object of the present invention to provide a hair cosmetic composition that maintains scalp freshness and freshness.

In order to achieve the above object, the present invention provides a hair cosmetic composition containing a powdered fragrance capsule prepared by encapsulating a powdered perfume that can provide a refreshing feeling of the scalp with a water-insoluble or poorly water-soluble coating.

The hair cosmetic composition according to the present invention contains powdered perfume capsules in which a powdered perfume having a relatively low solubility is encapsulated with a water-insoluble or poorly water-soluble coating agent, compared to a liquid perfume, so that the hair cosmetic composition contains water and a surfactant for a long time. When using it while ensuring that the coating was broken by physical force, the powdered fragrance adhered to the scalp and hair, and it was able to maintain the freshness and freshness for a long time.

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

Powder fragrance used in the present invention is menthol (Menthol), vanillin (Vanillin), 2-isopropyl-N, 2,3-trimethylbutyric amide (2-Isopropyl-N, 2,3) in a solid state at room temperature -trimethylbutyramide) and N-ethyl-p-methane-3-carboxamide can be used alone or in combination.

The coating agent used in the present invention is a material that is insoluble or poorly soluble in water and has a rigid structure that is destroyed by mechanical stimuli. For example, polyethylene glycol, methyl cellulose, hydroxypropyl cellulose, ethyl cellulose, hydroxyethyl cellulose, poly Vinyl alcohol, vinylpyrrolidone, vinyl acetate polymer, polyvinyl acetal dimethylamino acetate, polymethyl methacrylate, polystyrene, bees wax, paraffin wax, carnauba wax, petroleum wax and At least one selected from the group consisting of starch may be used.

In addition, the powder fragrance coating method is coated with a coacervation (spray drying), spray drying (spray drying), spray cooling (spray cooling), crystallization (co-crystallization) and fluidized bed (fluidized bed) method And the fluidized bed method is the most preferable. The fluidized bed method consists of a unit process of raw material conveying, mixing, coalescing, granulation and drying. That is, the powdered perfume capsule can be prepared by spraying the coating solution through the spray nozzle while flowing the powdered perfume by flowing air using a fluidized bed coater.

Powder fragrance capsule of the present invention prepared by the above method has a particle size of 100-1000㎛ in the form of a sphere, preferably has a particle size of 300-600㎛.

The hair cosmetic composition according to the present invention preferably contains the powdered flavor capsules in an amount of 0.01 to 10% by weight based on the total weight of the total composition. When the content of the powdered flavor capsules exceeds 10% by weight scalp stimulation or eye irritation may be expressed, if less than 0.01% by weight because it does not feel the refreshing effect.

The hair cosmetic composition of the present invention may have a conventional formulation and may be formulated, for example, as a shampoo, rinse, pomade, hair treatment and hair lotion. The hair cosmetic composition of each of these formulations may include various ingredients formulated into conventional hair cosmetic compositions according to the various formulations described above or as appropriate for the end purpose, and the types and amounts of these ingredients may be easily selected by those skilled in the art.

In addition, the freshness and persistence increased with the amount of added powder menthol capsules. Comparative Example 1 containing the same amount of menthol and Comparative Example 2 encapsulating liquid menthol obtained similar results.

Experimental Example 2 Evaluation of Powder Menthol Stability in Shampoo Formulations and Changes of Menthol Content in Capsules Over Time

The following tests were carried out to evaluate the stability of the powder menthol in the shampoo formulations rich in anionic surfactant and the change over time of the menthol content in the capsule.

First, the shampoo contents of Formulation Example 1 and Comparative Formulation Example 1 were stored in a constant temperature room for one week, one month, and three months at 0 ° C., 30 ° C., 40 ° C., and 50 ° C., respectively. It was. For Example 1, the stability and menthol content of the powdered menthol capsules were confirmed through visual observation and gas chromatography analysis, and the results are shown in Table 3 below. The menthol content is expressed in weight percent relative to the initial blending amount. In the case of Comparative Formulation Example 1, powder menthol was not confirmed even by appearance and touch, which was dissolved in the shampoo formulation of anionic surfactant immediately after preparation.
