Description

  The present invention relates to an emulsified hair cosmetic composition, and more specifically, when applied to hair and then washed away, the hair composition can impart a soft and coherent feeling to hair. Emulsified hair cosmetic composition that, when used in cosmetics that do not wash off after being applied to hair, such as cosmetics, can impart an appropriate setting force in addition to a soft and coherent feeling to the hair It is.

  In recent years, it has been common to repeat a chemical treatment such as applying a permanent treatment after the hair color, but by applying such a treatment, the hair state becomes a texture that is crisp, It becomes very difficult to make a desired hairstyle due to poor fit and poor hair mass.

  Currently, most hair cosmetics on the market contain a surfactant. A surfactant is, for example, an emulsifier for finely and uniformly dispersing a plurality of components that are difficult to mix with each other, such as water and oil, and a component that is inherently insoluble or hardly soluble in a solvent. As a solubilizer for dissolving in a solvent so as to become, further, it is used as a dispersant for uniformly and stably dispersing a component such as a pigment or a powder cake that tends to form a lump in a medium. .

  Surfactants can be broadly divided into anionic surfactants, cationic surfactants, nonionic surfactants, and amphoteric surfactants. Among them, cationic surfactants are positively charged in water. Therefore, it has high adsorptive power to hair, and can be expected to have the effect of imparting smoothness and softness to hair, which is one of the characteristics of cationic surfactants, so it can be used for hair treatments and hair conditioners. Many are included in cosmetics.

  However, even if hair cosmetics containing a cationic surfactant are applied to hair that has been repeatedly subjected to the chemical treatment as described above, the hair has a sense of unity to make it easier to make a desired hairstyle. It was difficult to give to.

  At present, in order to give the hair a feeling of unity, for example, a styling agent containing an anionic resin is used. In this case, the finished hair is soft. It usually has a problem that it tends to be stiff. Also, when a negatively charged anionic resin or the like is used in combination with a hair treatment or hair conditioner containing a cationic surfactant, an insolubilization phenomenon occurs due to the ionic bond between the two and the formation of a complex. Therefore, there arises a problem that the stability of the preparation is lowered. Therefore, in preparing hair cosmetics, it has not been possible to easily mix a cationic surfactant and an anionic resin.

  When seeking a current hair design, it is important to make the hair have a soft texture and a sense of unity, but usually the pursuit of a soft texture tends to impair the sense of unity, while the sense of unity These are in conflict with each other so that the soft texture is likely to be lost when pursuing. Currently, hair cosmetics including various hair treatments and styling agents are on the market. For example, because of the various problems described above, hair has a soft texture and a sense of unity. The current situation is not necessarily satisfactory in that it can be easily made into a state.

  Under such circumstances, as a cosmetic for hair that can give a unity so that a good hairstyle can be formed while enhancing the feel of the hair, it has a pH of 5 or less in which polyacrylamide is blended in Patent Document 1. A two-part hair treatment agent comprising a first agent and a second agent containing a cationic compound has been proposed.

JP 2006-124278 A

  However, the hair treatment agent described in Patent Document 1 is a two-component type, and the treatment process is complicated, such as applying the first agent to the hair and then applying the second agent, so that the hair salon or home When used in a bathroom or the like, there is a complexity in use that takes much time. Moreover, while the hair treatment agent described in Patent Document 1 is suitable for use in a type of washing away after being applied to hair, such as a hair treatment or a hair conditioner, it is applied to the hair like a hair conditioner. If it is applied to a type of application that will not be washed away later, the hair will become sticky.

  As described above, the hair treatment agent described in Patent Document 1 can have a good effect, but still has room for improvement in the above points.

  This invention is made | formed in view of the said situation, The objective is to provide the cosmetic composition for emulsification type hair which can also give a feeling of unity, providing softness to the hair after a process. .

  As a result of intensive studies to achieve the above object, the present inventors have used polyacrylamide as an anionic resin together with a cationic surfactant, a higher alcohol and a polyhydric alcohol, When the amount of acid amide and the amount of cationic surfactant are in a specific ratio, it can be formulated stably by suppressing the formation of impurities such as complex, and it has a cationic property such as a softening effect on hair. The present inventors have found that an emulsified hair cosmetic composition capable of imparting a sense of unity to hair while effectively exhibiting the action specific to a surfactant has been completed, and the present invention has been completed.

  That is, the emulsified hair cosmetic composition of the present invention contains a cationic surfactant, a higher alcohol, a polyhydric alcohol, and a polyacrylic amide, and the cationic surfactant with respect to the mass of the polyacrylic amide. The mass ratio is 3.5 or more.

  ADVANTAGE OF THE INVENTION According to this invention, the emulsification-type hair cosmetic composition which can also provide a unity feeling can be provided, providing softness. Moreover, since the emulsified hair cosmetic composition of the present invention is a one-component cosmetic, it is easy to treat the hair.

  The emulsified hair cosmetic composition of the present invention can be suitably used for hair cosmetics that are washed off after being applied to hair, such as hair treatments and hair conditioners, and suppresses stickiness of the hair after application. Therefore, it can be preferably used for hair cosmetics that are not washed off after being applied to hair, such as hair styling agents. In this case, a good setting power can be imparted to the hair.

  The cationic surfactant used in the emulsified hair cosmetic composition of the present invention is not particularly limited, and examples thereof include lauryl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, and lauryl trimethyl ammonium bromide.
