Description

  The present invention relates to a hair styling composition that can effectively bring out the flexibility-imparting action specific to a cationic surfactant and has good setting properties.

  Current hair styling products can be broadly categorized from the viewpoint of required functions. Those that place emphasis on setability, those that place emphasis on texture-improving effects such as flexibility and smoothness of the hair after treatment, and setability and texture improvement. It can be divided into those that have both action and action.

  By the way, the setting property and the texture improving effect are contradictory functions, and it is one of the difficult problems in developing a hairdressing material to achieve both of them.

  For example, in order to impart setability to a hairdressing material, blending a hairstyling polymer called a set resin is generally performed. There are various types and functions of the set resin. For example, acrylic polymers such as alkyl acrylate copolymers and acrylic acid / acrylic acid amide / ethyl acrylate copolymers are known as set resins having excellent setability and ability to maintain hairstyles. However, since these acrylic polymers have a hard film formed on the hair surface, they cause hair stiffness after applying a hairdressing agent, and sometimes cause flaking.

  On the other hand, cationic polymers such as celluloses and vinylpyrrolidone-alkyldialkylamino (meth) acrylate copolymers not only provide set properties but also set resins that can provide antistatic properties and a smooth feel to the hair. Known as. However, such a cationic polymer has a drawback that it cannot impart flexibility to the hair.

  In addition, nonionic polymers such as polyvinylpyrrolidone and vinyl acetate / vinylpyrrolidone copolymers are known as set resins that can impart an appropriate harshness to the hair because they can form a thin and hard film on the hair surface. It has been. However, the nonionic polymer has not only a deficiency in imparting flexibility to hair, but also has a drawback of lacking moisture resistance.

  Under such circumstances, a wax-like hair styling using microcrystalline wax or candelilla wax, which is also used as a hair fixative, in order to impart setability without forming the hard film found in set resins. Has been developed (Patent Document 1).

JP 2003-113054 A

  According to the hair styling described in Patent Document 1, good setability can be imparted without forming a hard film on the hair surface, but from the flexibility of the hair after application, that is, from slipping and smoothness on the hair surface. Not about the softness that is felt, but the softness that feels soft from the core of the hair is not always sufficient.

  It is known that it is effective to add a cationic surfactant to the hair styling agent in order to give the hair a softness that feels soft from its core. It is known from experience that even if a hairdressing composition is composed by blending an agent and the set resin, it is impossible to achieve both the setability and the effect of improving the flexibility of the hair.

  For this reason, there is a need for the development of a hair styling agent that has a good setting property and can impart softness that feels soft from the core to the hair.

  The present invention has been made in view of the above circumstances, and its purpose is to effectively bring out the flexibility-imparting action specific to the cationic surfactant, and has good setting properties. To provide things.

  The hair styling composition of the present invention that has achieved the above object is an emulsified hair styling composition in which at least a cationic surfactant, an oil component and water are blended, wherein the cationic surfactant is blended. The amount is 0.5 to 6% by mass, and at least a higher alcohol, a branched fatty acid and a wax are blended as the oil component.

  ADVANTAGE OF THE INVENTION According to this invention, the hair-styling composition which can draw out the softness | flexibility provision effect | action specific to cationic surfactant effectively, and has favorable set property can be provided.

  The hair styling composition of the present invention is an emulsified hair styling composition containing at least a cationic surfactant, an oil component and water. The cationic surfactant stably maintains the emulsified state of the hairdressing composition, and softens the hair that has been applied with the hairstyling composition from the core (hereinafter simply referred to as “flexibility”). It is a component for imparting "."

  There are no particular limitations on the cationic surfactant, but examples include monovalent compounds such as lauryltrimethylammonium chloride, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, lauryltrimethylammonium bromide, cetyltrimethylammonium bromide, and stearyltrimethylammonium bromide. Alkyl-type quaternary ammonium salts; dialkyl-type quaternary ammonium salts such as distearyldimethylammonium chloride, dicocoyldimethylammonium chloride, dicetyldimethylammonium chloride; benzalkonium type 4 such as benzalkonium chloride and stearyldimethylbenzylammonium chloride Grade ammonium; etc. are mentioned, Only 1 type of these may be used and 2 or more types may be used together. The cationic surfactant contributes to improving the flexibility of the hair, but also has an effect of impairing the setting properties of the hairdressing composition. However, monoalkyl quaternary ammonium such as cetyltrimethylammonium chloride and stearyltrimethylammonium chloride is more difficult to reduce the setting properties of the hairdressing composition compared to other cationic surfactants. Of these cationic surfactants, these are preferably used. Among the above-mentioned cationic surfactants, dialkyl quaternary ammonium slightly impairs the setting properties of the hairdressing composition compared to monoalkyl quaternary ammonium, but has the effect of imparting flexibility to the hair. It is preferable in terms of strength.

  The compounding amount of the cationic surfactant in the hairdressing composition allows the effects of the use of the cationic surfactant (stabilization of the emulsified state of the hairdressing composition and imparting flexibility to the hair) to be exhibited well. From a viewpoint, it is 0.5 mass% or more. Moreover, when there is too much amount of cationic surfactant in a hairdressing composition, while irritation | stimulation with respect to skin will become strong, it will become difficult to adjust the viscosity of a hairdressing composition and it will become difficult to provide set property. Therefore, the compounding quantity of the cationic surfactant in a hairdressing composition is 6 mass% or less. In addition, in order to make the hairdressing composition particularly an emulsion that is easy to adjust to hair, the amount of the cationic surfactant in the hairdressing composition is preferably 0.8% by mass or more, and 2 It is preferable that it is below mass%.

  In the hairdressing composition, at least a higher alcohol, a branched fatty acid and waxes are blended as an oil component. By using these materials as an oily component and forming a hairdressing composition together with the cationic surfactant, the cationic surfactant can be used without impairing the flexibility imparting action to the hair unique to the cationic surfactant. It is possible to secure a good setting property by suppressing the effect of lowering the setting property.

  By using higher alcohol as the oil component, the viscosity of the hairdressing composition can be adjusted, and by combining higher alcohol with the cationic surfactant, the softness unique to the cationic surfactant is imparted to the hair. It is possible to draw out the action to be better.

  The higher alcohol that can be used in the hairdressing composition is not particularly limited, and examples thereof include alcohols having 8 to 24 carbon atoms such as lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, oleyl alcohol, and behenyl alcohol. Only one of these may be used, or two or more may be used in combination.

  The blending amount of the higher alcohol in the hairdressing composition may vary depending on the drug substance required for the hairdressing composition.For example, when emphasizing ease of handling when applying the hairdressing composition to the hair, It is preferable that it is 1.5 mass% or more, and it is preferable that it is 7 mass% or less. Furthermore, from the viewpoint of further enhancing the synergistic effect between the higher alcohol and the cationic surfactant (the effect of effectively bringing out the flexibility imparting action to the hair by the cationic surfactant), the blend of the higher alcohol in the hairdressing composition. The amount is more preferably 2% by mass or more, and more preferably 5% by mass or less.

  Examples of the branched fatty acid used in the hairdressing composition include isononanoic acid, isooctanoic acid, isostearic acid, neopentanoic acid, neodecanoic acid, and 12-hydroxystearic acid, and only one of these is used. Or two or more of them may be used in combination. Among these branched fatty acids, isostearic acid and 12-hydroxystearic acid are preferable in that the unpleasant odor is very low, and isostearic acid is more preferable in that the viscosity stability over time of the hairdressing composition is higher. .

  The amount of the branched fatty acid in the hairdressing composition is not particularly limited as long as the emulsified state of the hairdressing composition is not impaired, so that better setability can be ensured in the hairdressing composition. From this viewpoint, the content is preferably 0.001% by mass or more. Further, if the amount of the branched fatty acid in the hairdressing composition is too large, the stickiness of the hairdressing composition becomes strong and the effect of imparting setability may be reduced. Therefore, the blending amount is 2% by mass. The following is preferable. In addition, since the flexibility imparting action to the hair by the hairdressing composition and the setability can be compatible at a higher level, the blended amount of the branched fatty acid in the hairdressing composition is 0.005 mass. % Or more, and more preferably 1% by mass or less.

  Examples of the waxes used in the hairdressing composition include carnauba wax, candelilla wax, sugar cane wax, beeswax, etc., and only one of them may be used, or two or more of them may be used in combination. Also good. Among these waxes, candelilla wax is preferable in that the setting property of the hairdressing composition can be improved satisfactorily by using a smaller amount.

  The amount of waxes in the hairdressing composition is not particularly limited as long as the emulsified state of the hairdressing composition is not impaired, but it is possible to ensure better setability in the hairdressing composition. From the viewpoint, it is preferably 0.001% by mass or more. In addition, if the amount of waxes in the hairdressing composition is too large, the stickiness of the hairdressing composition becomes strong and the effect of imparting setability may be reduced, so the blending amount is 2% by mass or less. It is preferable that

  The hairdressing composition of the present invention is an emulsion, and water is used as a dispersion medium. A part of the constituents of the hairdressing composition may be dissolved in water. It is preferable that the compounding quantity of the water in a hairdressing composition is 55-75 mass%, for example.

  In addition to the above-mentioned components, the hair styling composition of the present invention may be blended with various components blended in known hair cosmetics and other cosmetics, as long as the effects are not impaired. it can. Examples of such components include nonionic surfactants, amphoteric surfactants, alcohols other than higher alcohols, silicones, oils, esters, waxes other than waxes, fatty acids other than branched fatty acids, metals Examples include ion sequestering agents, antioxidants, pH adjusting agents, and fragrances.
