Description

Hair spray composition for hair setting

The present invention relates to a hairspray composition for hair, which is sprayed directly onto the hair to fix the hair so as to fix the hair. More specifically, the present invention includes a predetermined amount of a cationic surfactant component in a general hair spray composition including a setting polymer, a solvent, a plasticizer, a humectant, a fragrance, and the like to modify the properties of the setting polymer. The present invention relates to a hairspray composition, which increases flexibility and elasticity to a polymer film to be formed, so that the hair feels soft and supple after use, while maintaining the set state for a long time.

Humans have a desire to keep their hair in a variety of forms, and in order to satisfy these needs, various changes are being made to the hair. These changes can be roughly classified into permanent form changes and temporary form changes.

Permanent morphological changes of hair, such as permanent or semi-permanent changes in hair morphology or hair color through chemical reactions such as permanent agents or dyes, and physical properties of heat such as ironing perm. Methods are being used. This permanent morphology occurs through the degeneration of the protein. In other words, in chemical change, the cysteine bond (the bond between the sulfur atoms in the molecules constituting the protein) of the protein is temporarily cut to form a desired shape, and then the cleaved portion is bonded to the cysteine bond to maintain the modified form. For example, the physical change that utilizes the physical properties of heat is to use the degeneration of the protein by heat, to form the desired shape of the hair in the process of denatured protein by heating, and then to room temperature For example, to maintain the state deformed by natural cooling. However, all of the methods described above can deform the hair in a desired form and maintain it for a long time, but can cause severe damage to the hair both by cleavage and reconnection of cysteine bonds constituting the protein or by heat degeneration. There was this. In addition, there is a disadvantage that there are considerable restrictions to freely modify the shape of the hair from time to time.

In contrast, the temporary shape change of the hair is being performed using a hair setting product such as hairspray, hair mousse, hair gel, or physical methods using a weak heat of dry.

The general compression pump hairspray composition is composed of a setting polymer, a solvent, a plasticizer, a humectant and a fragrance, and the contents thereof are sprayed onto the hair in the form of fine particles by a conventional compression mist pump using a hand pressing pressure. Will be displayed. Setting polymer, one of the most important components, is used for the purpose of forming a film on the surface of the hair as a solvent such as ethanol or water evaporates after being injected into the hair and fixing the hair by the strength of the film. In addition, although ethanol is mainly used as a solvent, it may contain water in some cases, and as a plasticizer, a silicon compound or 2-amino-2-methyl-1-propanol (2-amino-2-methyl-1- propanol) and propylene glycol is mainly used as a moisturizing agent. However, in this case, when the setting polymer is used alone without using a plasticizer, a neutralizing agent, or a moisturizing agent, the polymer film is too hard and the elasticity and flexibility of the polymer film itself are poor. As the polymer film is easily broken by the impact, there is a problem in that it does not maintain the set state for a long time.

In order to prevent such a phenomenon, it is possible to soften the film of the polymer formed on the hair by the addition of a neutralizer, a humectant and a plasticizer, and to improve the feeling of hair after use. However, the addition of these plasticizers has the effect of softening the polymer film, but there is a problem that the setting force is reversed by the plasticizer and the time for which the setting is maintained is reduced.

Therefore, in the present invention, while minimizing adverse effects such as lowering of setting force and decreasing setting state of conventional plasticizers, the polymer film has been searched for various methods for providing a natural feeling to the hair after use by providing flexibility and elasticity to the polymer film. Among them, studies have focused on adding a certain amount of a cationic surfactant for the purpose of providing a hair conditioning effect to a hair shampoo, rinse, etc., and as a result, a conventional plasticizer by containing a predetermined amount of a cationic surfactant in the hairspray composition It gives flexibility and elasticity to the polymer film while minimizing the problem of lowering the setting force and shortening the setting time caused by the inclusion, and at the same time, it gives the hair shine and smoothness by utilizing the hair conditioning effect of the cationic surfactant. Compression Pump Hairs It confirmed that the ray can be obtained composition, thereby completing the present invention.

It is an object of the present invention to provide a hairspray composition which can provide a more improved feeling to a spray product by including a cationic surfactant in a hairspray composition in the form of a general compressed pump that does not use a propellant.

Another object of the present invention is to provide a hairspray composition which can improve the setting force and the setting holding time while providing flexibility and elasticity of the setting polymer.

Another object of the present invention is to provide a hairspray composition capable of imparting a conditioning effect on hair of a cationic surfactant.

Hair spray composition according to the present invention, 0.1 to 10% by weight of the active ingredient of the nonionic or amphoteric setting polymer with respect to the total composition, 1 to 40% by weight of the active ingredient content of the polymer for setting the cationic surfactant And a solvent as a residual amount.

The setting polymer may be a nonionic polymer such as polyvinylpyrrolidone, PVP / V copolymer, PVP / dimethylaminoethylmethacrylate copolymer, or the like. Or amphoterics such as methacryloylethyl betaine / methacrylate copolymer, octylacrylamide / acrylate / butylaminoethyl methacrylate copolymer (Octylacrylamide / acrylates / butylaminoethyl methacrylate copolymer) Polymers or mixtures of two or more of these may be used.

The cationic surfactant is an alkyl trimethyl ammonium halide having 16 to 22 carbon atoms in the alkyl portion, an alkyl dimethyl ammonium halide having 16 to 22 carbon atoms in the alkyl portion, and an alkyl portion having 16 carbon atoms. Trialkylmethyl ammonium halide of from 22 to 22 or a mixture of two or more thereof may be used.

Hereinafter, the present invention will be described in detail with reference to specific embodiments.

The hairspray composition according to the present invention is characterized by including a cationic surfactant in the setting polymer so as to impart the flexibility and elasticity of the film formed by the polymer and at the same time provide a conditioning effect on the hair. .

The setting polymer serves to set the hair by forming a film on the surface of the hair by removing the solvent when spraying the hair. The setting polymer is a nonionic or amphoteric polymer, and may include 0.1 to 10 wt. When the content of the setting polymer is less than 0.1 weight, there may be a problem that the amount of the polymer forming the hair setting force is too small to form an effective film. On the contrary, when the content exceeds 10 weight, the polymer is excessively used. There may be a problem that is not included enough injection by the compression pump. As the polymer for setting, nonionic properties such as polyvinylpyrrolidone, PVP / VA copolymer, PVP / dimethylaminoethylmethacrylate copolymer, etc. Both polymers or methacryloylethyl betaine / methacrylate copolymers, octyacrylamide / acrylates / butylaminoethyl methacrylate copolymers, and others such as octylacrylamide / acrylates / butylaminoethyl methacrylate copolymers. One selected from the group consisting of sex polymers or mixtures of two or more thereof can be used. Anionic polymers, such as V / crotonates / vinyl neodecanoate copolymers, may be restricted in terms of ionicity with the cationic surfactant mixed therein, Cationic polymers such as Polyquaternium-11 are generally used for setting polymers such as hair mousse and hair gel products due to their low setting power.However, application to hair spray is limited. There may be a problem.

In order to increase the flexibility and elasticity of the setting polymer, the cationic surfactant used in the present invention is replaced with the plasticizer in the conventional hair spray in an amount of 1 to 40 weight based on the active ingredient content of the setting polymer. It may be included in the composition. The cationic surfactant may improve the flexibility and elasticity of the setting polymer to prevent the lowering of the setting force, and increase the setting holding time, thereby providing a conditioning effect to the hair. The cationic surfactant is an alkyl trimethyl ammonium halide having 16 to 22 carbon atoms in the alkyl portion, an alkyl dimethyl ammonium halide having 16 to 22 carbon atoms in the alkyl portion, and an alkyl portion having 16 carbon atoms. Trialkylmethyl ammonium halide of from 22 to 22 or a mixture of two or more thereof may be used. When the cationic surfactant is included in an amount less than 1 wt.% Based on the active ingredient content of the setting polymer, there may be a problem in that the film formed on the surface of the hair by the setting polymer does not sufficiently exhibit elasticity and flexibility effects. On the contrary, even if it exceeds 40 weight, there may be a problem of decreasing the setting force and shortening the setting holding time, causing the occurrence of temporary fine bubble phenomenon in the sprayed part after the injection.

The setting polymer and the cationic surfactant are dissolved in the remaining solvent and put into a container equipped with a manual compression pump. The solvent keeps the setting polymer in a flow state and is pumped by a manual compression pump, and then easily evaporated after being applied to the hair. Only the non-volatile setting polymer remains on the surface of the hair to form a film. The film remaining on the surface of the hair supports the hair and fixes it to exhibit the hair setting force. At this time, the non-volatile cationic surfactants are mixed with the setting polymer and remain on the surface of the hair together with the setting polymer, thereby improving the flexibility and elasticity of the setting polymer and giving the hair a conditioning effect. Preferably, as the solvent, lower alcohols having 1 to 4 carbon atoms such as ethanol may be mainly used, and more preferably ethanol may be used.

In addition to the above-described setting polymer, cationic surfactant, and solvent, the hairspray composition according to the present invention may further contain silicone compounds for fragrance to increase user's feeling, such as neutralizing agent and gloss, etc. And the addition of such additional ingredients is well known to those skilled in the art.

In addition, although the use of conventional aerosol propellants such as propane, butane, dimethyl ether (DME) can be considered, the solubility of the cationic surfactant components used in the present invention in these propellants is generally low. There may be a problem that can form a precipitate during distribution, storage, thereby making it difficult to form a suitable film.

Setting Effect Test Example

Preparation of test sample

In the case of Comparative Examples 1 and 3, a fibpy / V copolymer or a methacryloylethylbetaine / methacrylate copolymer was added to ethanol and dissolved with stirring until completely dissolved, and propylene glycol, Incense was added sequentially to prepare a stock solution.

In the case of Comparative Examples 2 and 4, a fibpy / V copolymer or a methacryloylethylbetaine / methacrylate copolymer was added to ethanol and dissolved with stirring until complete dissolution, and then cyclomethicone was added to the solution. , Propylene glycol, flavor was added sequentially to prepare a stock solution.

In Examples 1 to 12, the cationic surfactants such as cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, disetyldimethylammonium chloride, and distearyldimethylammonium chloride were quantitatively added to ethanol, followed by stirring. After completely dissolving, the solution was added with a fip / V copolymer or a methacryloylethylbetaine / methacrylate copolymer and dissolved with stirring until completely dissolved, and then dissolved in this solution. To prepare sequentially the stock solution.

The stock solution of Comparative Examples and Examples prepared as described above was put into a container equipped with a conventional manual compression pump to prepare a product.

Setting effect test

The setting effect test by the product of the comparative examples and examples prepared as described above was performed as follows. First, the hairspray stock solution was evenly applied to the hair. Subsequently, uncoated hair is wound on a spiral spiral and dried, and the dried hair is separated from the spiral and placed in a thermo-hygrostat (25 ° C, 90 RH) to increase curl as time passes. It was measured by the method of comparing the setting effect by the conventional curl retention method (see J. Soc. Cosmetic. Dec. 9, 1968). Was calculated according to the following equation (1).

Crr () = {(Lo-Lt) / (Lo-Ls)} * 100

Where

Crr () is the curl-retention rate,

L _o is the length of hair used in the experiment,

L _t is the length of hair after t hours,

L _s is the initial length (t = 0) of the hair wound in a spiral.

For comparative tests of the flexibility and elasticity of the setting polymer films for Comparative Examples 1 to 4 and Examples 1 to 12, the stock solution was evenly applied to wool fibers of the same size similar to that of hair, and dried and bent. Bending force and hysteresis (hysteresis) were measured and compared using a bending tester, respectively.

Judging from the test result, in the case of the setting effect test, it was determined that the larger the value of the curl-retention rate was, the higher the setting force was, and in the case of flexibility, the smaller the value of the bending force measured by the bending tester, the harder the hardness was. It was judged to be weak, ie flexible, and in the case of elasticity, the smaller the value of hysteresis measured by the bending force tester, the more elastic and flexible the film was judged.

Three test results of curl-retention rate, bending force, and hysteresis by the test method as described above are shown in Table 3 below.

Curl-Retention Rate () Bending force (gfcm ² / cm) Hysteresis (gf · cm ² / cm) Example 1 83.5 0.38 0.88 Example 2 83.1 0.35 0.86 Example 3 85.2 0.32 0.82 Example 4 84.1 0.37 0.83 Example 5 77.2 0.18 0.63 Example 6 84.3 0.40 0.87 Example 7 91.5 0.46 1.16 Example 8 92.0 0.2 1.13 Example 9 91.8 0.46 1.18 Example 10 92.5 0.45 1.15 Example 11 84.7 0.22 0.72 Example 12 91.9 0.46 1.17 Comparative Example 1 85.3 0.61 1.58 Comparative Example 2 75.1 0.42 0.87 Comparative Example 3 92.6 0.72 1.70 Comparative Example 4 82.6 0.45 1.02

When only a small amount of propylene glycol alone was used as the plasticizer as in Comparative Examples 1 and 3, the setting force was strong, but the flexibility and elasticity were not found. On the contrary, the plasticizer of the general hair spray was used as in Comparative Examples 2 and 4. As a result of using the cyclomethicone in an amount of 20 weight based on the content of the polymer active ingredient, the elasticity and flexibility were improved while the setting force was greatly decreased. In contrast, as in the case of Examples 1 to 4 and Examples 7 to 10, a nonionic fibrous V / B copolymer or an amphoteric methacryloylethylbetaine / methacrylate copolymer is used as the setting polymer. While the cationic surfactant was used in an amount of 20% by weight based on the content of the polymer active ingredient, it showed that the elasticity and flexibility were excellent while showing a similar level of setting force as in the case of using only each polymer. In this case, as in Examples 5 and 11, when the cationic surfactant was contained in an excess of 50 wt.% Based on the polymer active ingredient content, the elasticity and flexibility were increased while the setting force was greatly decreased. In addition, as in Examples 6 and 12, when cationic surfactant components such as alkyltrimethylammonium chloride and dialkyldimethylammonium chloride were mixed to each other to be used in an amount of 20 wt. As in the case, the elasticity and the flexibility were excellent while the level of the setting force was similar to that of the polymer alone.

This elasticity and flexibility improvement effect is due to the affinity between the hydrophobic portion of the polymer and the hydrophobic portion of the cationic surfactant in the stock solution to form a mixed micelle structure of the cationic surfactant in the hydrophobic portion of the polymer, the orientation of the polymer chain By changing to a more parallel structure, the fixing force of the polymer itself does not change, but it is considered to change the film more flexibly and elastically.

Therefore, according to the present invention, by including a cationic surfactant in the hairspray composition comprising the setting polymer, the setting polymer can be applied to the hair to improve the flexibility and elasticity while simultaneously providing a conditioning effect. It is effective to provide a more improved form of the hairspray composition.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
