Description

High-flexible Hairspray Compositions

The present invention relates to a high elastic hairspray composition. More specifically, the present invention improves the flexibility and elasticity of the film by modifying the properties of the setting polymer by containing a certain amount of a higher fatty acid component in the hairspray composition, especially among hair fixative compositions using aerosol or compression pump. It relates to a hairspray composition of aerosol and compression pump formulations characterized in that the hair feels softer and more pliable compared to previous products after spraying, while maintaining the set state for a long time.

Humans have a desire to keep their hair in various forms and are trying various changes to their hair to meet these needs. These changes can be largely classified into permanent and temporary methods. First of all, the morphological change of hair forms permanently changing the shape of the hair or changing the color of the hair through a chemical reaction such as a permanent agent or a dye. Methods using the physical properties of heat, such as perm, are being used.

On the other hand, the temporary shape change of the hair is using physical methods using hair fixation products such as hairspray, hair mousse, hair gel, or using a weak heat of dry.

The present invention aims to provide a more improved feel quality to the hairspray products used for the temporary shape change among these various methods of hair shape change.

Typical hairspray compositions consist of other components such as solvents, setting polymers, plasticizers, fragrances, and moisturizers, and their contents are aerosol products that are sprayed by pulverizing from liquefied or compressed gases, depending on how they are sprayed, and by hand pressure It can be roughly divided into a pump type that is sprayed to the hair in the form of fine particles by a conventional compression mast pump using the to exhibit its action. In these compositions, ethanol is mainly used as the solvent, but it may contain water in some cases, and plasticizers such as 2-amino-2-methyl-1 propanol or neutralizing agents, moisturizing ingredients such as propylene glycol, and fragrances are used. In addition, in the case of aerosol products, liquefied petroleum gas (LPG) such as propane and butane or hydrochlorofluorocarbons or hydrofluorocarbons or dimethyl ether may be used alone or in combination, or carbon dioxide, nitrogen oxide, Compress gas such as nitrogen gas and use alone or mixed.

Setting polymer, one of the most important compositions, 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. However, in this case, when the setting polymer is used alone without using a plasticizer, a neutralizing agent, or a moisturizing component, the polymer film is too hard and the elasticity and flexibility of the polymer film itself are poor, resulting in unnatural hair after use and external physical impact. As the polymer film is easily broken, the polymer film may not be maintained for a long time.

In order to prevent such a phenomenon, plasticizers such as neutralizers, moisturizing components, and silicones are added as components for softening the polymer film formed on the hair and improving the hair feeling after use. However, the addition of such a plastic component has the effect of softening the polymer film, but exhibits a reverse function such as a problem that the setting force is lowered and the time for which the setting is maintained is limited, so the content thereof is extremely limited, and accordingly, a certain level. While maintaining the setting of the film has been limited to soften the film or increase the elasticity. In addition, when the cationic surfactant is applied, the elasticity is increased without decreasing the setting force.However, when applied to the aerosol, the aerosol is applied due to the problems related to compatibility with liquefied petroleum gas (LPG) or dimethyl ether such as propane and butane as a propellant. The application of the product was found to be impossible.

Accordingly, the present inventors show excellent compatibility with conventional propellants such as LPG and dimethyl ether while reducing the setting force and reducing the effect of maintaining the state of the conventional plasticized additives. While exploring various methods for applying to products and providing a natural feel to hair after use by providing flexibility and elasticity to polymer films, oily ingredients in cosmetic raw materials are typically Focusing on the fact that it is being used, various oil-based raw materials have been studied and examined.As a result, by containing a certain amount of higher fatty acids in the hair spray stock solution, polymer film can be minimized while minimizing the problem of lowering the setting force and shortening the setting time caused by the existing plasticizer. Flexibility and burnt in Have sex and at the same time out utilizing a hair conditioning benefits of fatty acids found that you can get a hair spray composition which can give a sense of flexibility to the hair, thereby completing the present invention.

The present invention contains a polymer for setting of 0.1 to 10% by weight of the active content in the composition and at 1 to 40 with respect to the active content of the polymer, in order to make the polymer film of the hairspray flexible and elastic, and exhibit an excellent setting retention effect. A hairspray composition, characterized in that it contains, alone or in combination, by weight higher fatty acid components.

The main composition of the present invention is methacryloylethylbetaine / methacrylate copolymer, octylacrylamide / acrylate / as a polymer for setting while using ethanol which is a solvent used in a conventional hair spray as a main solvent. Amphoteric polymers such as butylaminoethyl methacrylate copolymers or polyvinylpyrrolidone, PVP / VA copolymers, PIV / dimethylmethylethyl methacrylate copolymers (P

Nonionic polymers such as VP / Dimethylaminoethylmethacrylate Copolymer) and anionic polymers such as acrylate methacrylate copolymers, V / crotonate / vinyl neodecanoate copolymers (VA / Crotonates / Vinyl Neodecanoate Copolymer) It can be used alone or mixed so as not to form a precipitate with respect to ionicity so as to be 0.1 to 10% by weight of the active content, more preferably methacryloylethylbetaine / methacrylate copolymer alone or Mixing may be used such that its active content is from 4 to 6% by weight. In general, cationic polymers such as polyquaternium-11 have low setting powers, and thus are mainly used as setting polymers for hair mousse and hair gel products. However, their use in hair spraying applications is extremely limited.

The hairspray composition of the present invention may contain a fragrance, a neutralizer, a silicone component, and the like used in a conventional hair spray in addition to the setting poly-component. However, in the present invention, by containing a certain amount of saturated or unsaturated higher fatty acid component in such a composition to modify the properties of the setting polymer to improve the flexibility and elasticity of the film to give a softer hair compared to the previous products after using hair spray It feels flexible, but keeps it set longer.

Spray prescription features for this purpose are saturated or unsaturated fatty acids having 8 to 22 carbon atoms in the alkyl moiety caprylic acid (CH ₃ (CH ₂ ) ₆ COOH), capric acid (CH ₃ (CH ₂ ) ₈ CO OH), lauric acid (CH ₃ (CH ₂ ) ₁₀ COOH), myristic acid (CH ₃ (CH ₂ ) ₁₂ COOH), palmitic acid (CH ₃ (CH ₂ ) ₁₄ COO

H) or stearic acid (CH ₃ (CH ₂ ) ₁₆ COOH), arachidic acid (CH ₃ (CH ₂ ) ₁₈ COOH) or behenic acid (CH ₃

And (CH ₂ ) ₂₀ COOH). In addition, higher fatty acids may be contained in an amount of 1 to 40% by weight alone or in combination with respect to the polymer active content used in the prescription. When the content of higher fatty acids is used in less than 1% by weight relative to the polymer active content, the film elasticity and softening effect do not appear to be recognizable, and when used in excess of 40% by weight, the setting force decreases and the setting holding time It causes problems such as shortening, solubility in ethanol as a main solvent, compatibility with LPG or DME gas as a propellant, and white powder generation at the sprayed part after injection.

Hereinafter, the present invention will be described in detail with reference to Examples, but these Examples do not limit the technical scope of the present invention.

Test Example

The setting effect test for Comparative Examples 1 to 4 and Examples 1 to 12 prepared by the above manufacturing method was carried out by drying the hairspray undiluted hair on spiral spirals and drying the separated hairs from spirals. It is measured by the method of relative comparison of the setting effect by the usual curl retention method, which is a method of comparing the degree of curling with time as it is put in a constant temperature and humidity chamber (25 ° C, 90 RH%). (

J.Soc. Cosmetic Chemists. Dex 9. 1968), the equation used to calculate the percent retention is:

In the comparative test of the flexibility and elasticity of the polymer film for Comparative Examples 1 to 4 and Examples 1 to 12, the stock solution was evenly applied to the wool fibers of the same size having similar characteristics to the hair, and dried and the bending force The bending force and hysteresis were measured and compared by using a bending tester, and the judgment of the test result was determined that the larger the tension value at 25 ° C. and 90 RH%, the higher the setting force was. The smaller the value of the bending force measured by the experimenter, the weaker the hardness, and the smaller the value of the hysteresis measured by the bending force tester, the film was judged to be more elastic and flexible.

In the case of using only a small amount of propylene glycol alone as a plasticizer as in Comparative Examples 1 and 3, the setting force was found to be strong but no flexibility and elasticity, and on the contrary, it was used as a plasticizer for general hair spray as in Comparative Examples 2 and 4. As a result of using the cyclomethicone in an amount of 20% by weight based on the polymer active content, the elasticity and flexibility were improved while the setting force was greatly decreased. On the other hand, as in the case of Examples 1 to 4 and Examples 7 to 10, while using a nonionic amphoteric methacryloylethylbetaine / methacrylate copolymer or FV / V copolymer as the setting polymer, When the higher fatty acid component was used in an amount of 20% by weight based on the active content of the polymer, it showed a high level of elasticity and flexibility while showing a similar level of setting force as in the case of using only each polymer. In this case, too, when the excess fatty acid is contained in an amount of 50% by weight based on the polymer active content as in Examples 5 and 11, the elasticity and flexibility are increased while the setting force is greatly decreased and white powder is generated when used in the hair. The phenomenon was shown. In addition, as in Examples 6 and 12, a mixture of stearic acid having 16 carbon atoms in the higher fatty acids and lauric acid having 10 alkyl carbon atoms in the higher fatty acids was also used in combination so as to be 20% by weight based on the polymer active content. In the same manner as the case of using only the polymer, but showed a level of setting power, the elasticity and flexibility was excellent.

This elasticity and flexibility improvement effect is formed by forming a hydrophobic binding between the hydrophobic portion of the polymer and the hydrophobic portion of the higher fatty acid by the hydrophobic portion of the polymer and the hydrophobic portion of the higher fatty acid. The formation of the film imparts the oily properties of the higher fatty acids to the film, making the film more flexible and elastic, which is believed to be the hydrophobic part of the polymer and the minority of the cationic surfactant, which is the interaction between the polymer and the surfactant. The affinity of the moieties results in the formation of mixed micelle structures of cationic surfactants in the minor part of the polymer, changing the orientation of the polymer chains to a more parallel structure and as the properties of the oriented surfactants are imparted to the polymer film The fixing force of the polymer itself does not change, but the film It is presumed to exhibit a flexible and similar to the phenomenon that elastically changes in behavior (see:. Principles of Polymer Science and Technology in Cosmetics and Personal Care Edited by E. Desmond Goddard, [. P 242])
