Description

  The present invention provides a hair styling composition capable of imparting a soft touch and luster to the hair when used on hair, having good hair cohesiveness, and having excellent set retention, and the hair styling composition The present invention relates to a hair foam using the composition.

  Currently, there are various types of hair styling agents in the beauty market, such as sprays, foams, gels, waxes, liquids, creams, and emulsions.

  Such a hair styling agent usually contains a set resin, a solid wax having a relatively high melting point, or the like in order to maintain a finished hairstyle. For example, in the case of a spray-like hair styling agent, the sprayed contents are uniformly attached to the surface of the prepared hair, and a thin film made of a set resin or a solid wax with a high melting point is formed to maintain the hairstyle. There are a lot of things. According to such a hair styling agent, a strong set holding force can be obtained, but there is also a problem that a finger cannot be passed through the hair.

  In the case of a cream-like or gel-like hair styling agent, it is often applied evenly to the hair using the hand, so that it is desired to make the agent easy to extend. Therefore, generally, the viscosity is often set low. Moreover, since it is cream-like or gel-like, it is easy to mix water-insoluble silicones and oils, and therefore, it is possible to easily give the hair after application, such as gloss and softness. However, since the dosage form contains a lot of moisture, the set holding power is relatively weak, and it tends to be difficult to make a desired hairstyle.

  In the case of a wax-like hair styling agent, many of them have a stronger set retention force depending on the agent shape. However, since the agent is hard, there is a drawback that the elongation at the time of application to hair is bad or the hair after application is sticky.

  In the case of a liquid or emulsion hair styling agent, it is difficult to apply it to the hair after it has been stretched once on the palm and then applied to the hair. There is a problem that it cannot be maintained.

  Since the foam-like hair styling agent is applied so as to wrap the entire hair during use, it can be uniformly applied to the entire hair, and is particularly suitable for maintaining the style of hair having a permanent wave shape. However, there is also a drawback that the set holding force is relatively weak because it contains a lot of moisture as compared with, for example, a spray-like styling agent.

  In hair styling agents, inorganic powders such as kaolin and talc are often blended in order to compensate for various drawbacks due to the above-mentioned dosage forms. For example, Patent Document 1 proposes a hair styling composition, particularly a cream-like and wax-like hair styling composition, which contains a solid wax, a water-soluble polymer, a liquid oil at room temperature, a powder such as silica or kaolin, and water. Yes. Patent Document 2 proposes a hair foam that uses a stock solution containing dimerisolinic acid diisostearate, kaolin, and polyethylene glycol, and a propellant.

  For example, the hair foam disclosed in Patent Document 2 can reduce the mass of the hair after use, has good hair cohesiveness, and can impart luster like hair to the hair. Various problems due to the dosage form of the hair styling agent as described above can be solved to some extent.

  However, with a hair styling agent using inorganic powder, it is easy to ensure a good set holding power, but there is a tendency that the harsh feel on the hair after application tends to be strong. Recently, there is also a demand for the development of a hair styling agent that can increase the gloss of the hair after application. For this reason, there is still room for improvement in the hair foam disclosed in Patent Document 2.

  The present invention has been made in view of the above circumstances, and its purpose is to impart good gloss and fluffy soft touch to the hair after application, good hair cohesiveness, and excellent set retention. The object is to provide a hairdressing composition having strength and a hair foam containing the hairdressing composition.

  As a result of intensive studies, the present inventors have given a good gloss to the hair after application if it is a hairdressing composition composed of a specific amount of sterols and a specific amount of inorganic powder in combination. In addition, it suppresses the harsh feel of hair that can occur when using inorganic powders, making the hair feel soft and soft, and the hair can be bundled well, and the hair style is improved. As a result, the present invention has been completed.

  That is, the hairdressing composition of the present invention is characterized by containing at least 0.01 to 0.5% by mass of sterols and 0.01 to 2% by mass of inorganic powder. .

  Moreover, the hair foam of the present invention contains the hair styling composition of the present invention and a propellant. The “hair foam” as used in the present invention means that the hair styling composition becomes a foam when ejected from a container by the action of a propellant.

  According to the present invention, a hair styling composition capable of imparting a good gloss and soft touch to the hair after application, having good hair cohesiveness, and having excellent set holding power, and the hair styling composition Hair foams containing the composition can be provided. With the hair foam of the present invention, it is possible to obtain a foamy foam having a fine texture and a beautiful appearance.

  The hairdressing composition of the present invention contains at least sterols and inorganic powder.

  Examples of the sterols according to the present invention include fucosterol (melting point 124 ° C.), ditosterol (melting point 140 ° C.), cholesterol (melting point 149 ° C.), campesterol (melting point 157 ° C.), stigmasterol (melting point 170 ° C.). Etc. Moreover, the phytosterol which contains a campesterol as a main sterol component can also be used preferably.

  The reason is not clear, but among the above-exemplified sterols, sterols having a melting point of 145 to 160 ° C. are preferable because the hair becomes less sticky after the hairdressing composition is applied. Moreover, cholesterol and campesterol (phytosterol) are more preferable in that the effect of the hairdressing composition of the present invention is better, and cholesterol is more preferable in terms of particularly excellent effect.

  Examples of commercially available cholesterol products include those manufactured by Nippon Seika Co., Ltd. Examples of commercially available products of phytosterol include “Phytosterol (trade name)” manufactured by Eisai Co., Ltd. and “Phytosterol-S (trade name)” manufactured by Tama Seikagaku Co., Ltd.

  The content (blending amount) of sterols in the hairdressing composition is 0.01% by mass or more and 0.5% by mass or less. In this way, the amount of sterols in the hair styling composition is used to eliminate the unnatural appearance such as matte feeling and dry feeling caused by inorganic powder after applying to the hair, and to maintain the set holding power. It will be possible to impart the firmness and stiffness to the hair. That is, if the amount of sterols in the hairdressing composition is too small, sufficient hair and firmness cannot be given to the hair, and in particular, when the hairdressing composition is applied to soft hair, the set holding power is poor. It becomes enough and cannot maintain a hairstyle. Moreover, when there is too much quantity of sterols in a hairdressing composition, it will give excessive stickiness to hair and the fingering of hair will worsen.

  In addition, it is preferable that content (blending amount) of sterols in a hairdressing composition is 0.1 mass% or more, and it is preferable that it is 0.5 mass% or less. In the case of a hairdressing composition containing sterols in such an amount, when the dosage form is made into a foam (details will be described later), it can be made into a fine foam with fine texture.

  Examples of the inorganic powder according to the present invention include inorganic powders used in ordinary cosmetics. Among them, those obtained by grinding clay minerals such as kaolin and talc, and aluminum magnesium silicate obtained by purifying by leaving only the colloid-forming component from the slurry of smectite / clay mineral are applied to the hairdressing composition. The hair can be raised gently, and when used in combination with sterols, it can more effectively suppress matting and dryness without reducing the holding power of the set, and it is also excellent in safety. To preferred. As the inorganic powder, those exemplified above may be used alone or in combination of two or more.

  In addition, as a particle size of inorganic powder, it is preferable that it is 4-10 micrometers by an average particle diameter, for example. If it is an inorganic powder of such a particle size, the effect by this invention can be ensured more favorably.

  The content (blending amount) of the inorganic powder in the hairdressing composition is 0.01% by mass or more and 2% by mass or less. By setting the amount of the inorganic powder in the hairdressing composition in this way, the hair coated with the hairdressing composition can adhere the inorganic powder to the surface relatively uniformly and appropriately. The hair is caught between the hairs, the holding power of the set is improved, and the hairstyle can be maintained well. That is, if the amount of the inorganic powder in the hairdressing composition is too small, it becomes difficult for the hair and hair to get caught after application, the set holding power becomes insufficient, and the hairstyle becomes difficult to maintain. Further, if the amount of the inorganic powder in the hairdressing composition is too large, even if sterols are used in combination, the hair after application cannot be given a soft and soft feel, and the hair feels stiff. .

  The content (blending amount) of the inorganic powder in the hairdressing composition is preferably 0.05% by mass or more, and more preferably 0.5% by mass or less. In the case of a hairdressing composition containing inorganic powder in such an amount, smoother fingering can be obtained in the hair after application.

  In addition, hair styling compositions containing sterols and inorganic powders include I.V. O. It is preferable to further blend a liquid ester oil having a B value of 0.1 or more and 0.4 or less. In this case, the cohesiveness and gloss of the hair can be further improved. I. O. When a liquid ester having a B value that is too small is used, the oiliness of the hairdressing composition may become strong and stickiness may occur. O. When a liquid ester having an excessively large B value is used, water-like weight tends to appear on the hair coated with the hairdressing composition, and the hairstyle tends to collapse.

  The above-mentioned I.I. O. Liquid esters are preferred as ester oils having a B value. When ester oils that are not liquid, for example, ester oils that are solid at room temperature, are used, the elongation of the hairdressing composition on the palm or hair is reduced. This is because the hair mass after finishing tends to decrease.

  In the hair styling composition of the present invention, I. O. The ester oil having B value and the solid ester are not excluded. As will be described later, such an ester can also be blended within a range not impairing the effects of the present invention.
