Description

Hair cosmetics

The invention relates to a hair cosmetic.

Hair will be damaged due to living environment (ultraviolet rays or heat generated by sunlight), daily hair care behavior (friction caused by shampooing or combing), and chemical treatment (coloring, perming, etc.). If the damaged hairs rub against each other, a large frictional force will be generated on the surface, resulting in tangles. "Tangle of hair" becomes the cause of all stress in hair care behaviors. The "complexity of hair" was felt due to poor combability in the operation of foaming the hair cleanser such as shampoo during shampooing, and poor combability of the hair after washing the hair after washing. As a method of untangling hair after shampooing, when using hair cosmetics such as conditioner or treatment, apply the hair cosmetics to the hair and apply on one side Comb your fingers through the tangled area to fuse them, so that the lubricating ingredients spread over the surface of the hair and untie the hair. In the prior art, in order to improve the combability or combability of the hair, cationic surfactants, higher alcohols, polysiloxanes, etc. are blended in hair cosmetics such as conditioners or repairing agents.

Patent Document 1 discloses a hair cosmetic using a polyetheramine-modified polysiloxane and a cationic surfactant. By suppressing the dryness of the hair in the water flow during cleaning, the softness or smoothness is improved, which can prevent the cleaning. Damage caused by the tangles of time hair. Patent Document 2 discloses that a combination of amine-modified polysiloxane in a specific dynamic viscosity range, amino-polyether-modified polysiloxane, dimethyl polysiloxane in a specific dynamic viscosity range, specific The alkyl cations and specific higher alcohol hair cosmetics can improve the moisture retention of the hair and improve the combability during use, thereby giving a soft and hydrated modification, and preventing dryness under low humidity. Moisture. In addition, Patent Document 3 discloses that co-modified polysiloxane and volatile polysiloxane co-modified with an amino polyether of a specific structure in hair cosmetics used for post-hair washing, adsorption of sticky components on hair The amount becomes smaller, and the bulky adhesive component is not easy to adhere to the hair. As a result, the wet hair after the treatment is easily dispersed and the drying speed is increased. [Prior Technical Literature] [Patent Literature]

The present invention relates to a hair cosmetics which contains or is formulated with an amine-based polyether-modified polysiloxane (A) having a polyoxyalkylene structure in the side chain part and a polyoxyalkylene group in the main chain part Amino polyether modified polysiloxane (B).

[Hair cosmetics] The hair cosmetic of the present invention is characterized in that it contains or is blended with an amine-based polyether-modified polysiloxane (A) having a polyoxyalkylene structure on the side chain (hereinafter, also referred to as "component (A) "), and an amine polyether modified polysiloxane (B) (hereinafter, also referred to as "component (B)") having a polyoxyalkylene structure in the main chain portion. The amine group in the component (A) and the component (B) may be any one of primary to tertiary amine groups. In addition, the amine may be present based on any of the main chain part and the side chain part of the component (A) and the component (B), and it is preferably present in the side chain part. The hair cosmetic of the present invention contains or mixes the above-mentioned component (A) and component (B) together, and when applied to the hair, it can solve the tangles without performing operations such as combing the hair by hand. Furthermore, the drying speed of the treated hair can be increased, and smoothness can be imparted to the hair during washing. In addition, "contained component (A) and component (B)" here also means "made up of component (A) and component (B)".

For the hair cosmetics described in Patent Documents 1 to 3, although the smoothness, combability, and drying speed of the hair during use are improved, it does not reach the situation where no operation such as combing the hair by hand is performed Next, spontaneously unravel the degree of tangles in hair. The present invention relates to a hair cosmetic. If it is applied to hair, the tangles can be disentangled without combing by hand, etc., and the drying speed of the treated hair can be increased. Gives smoothness.

The inventors found that hair cosmetics containing or blending two kinds of amino polyether modified polysiloxanes with specific structures can solve the above problems. If the hair cosmetic of the present invention is applied to hair, the tangles can be solved without performing operations such as combing the hair by hand. In addition, the hair applied with the hair cosmetics dries faster, and the smoothness of the hair during washing is also good.

The reason why the effect of the present invention is exerted by the hair cosmetic of the present invention as described above is not clear, but it is presumed as follows. It can be considered that it is important to reduce the friction force acting between the hairs in order to achieve a state where the tangles of hairs generated during shampooing or the tangles of hairs existing after shampooing spontaneously unravel. It may be considered that although polysiloxane is blended as an effective ingredient in hair cosmetics, if it is used as a component (B) which is a highly water soluble amino polyether modified polysiloxane, it can be reduced from the hair to the hair. The frictional force exerted therefore exhibits the effect of untangling the hair. In addition, by using the component (A), the drying speed of the hair treated with the hair cosmetics can be increased, and smoothness can also be imparted to the hair during washing. Furthermore, the present inventors found that by using the component (A) and the component (B) together, it is possible to solve the tangles of hair more effectively than when the component (B) is separately formulated.

Examples of the hair cosmetics of the present invention include: conditioner, conditioning agent, repairing agent (including no-rinse type), styling agent, hair cleanser, hair dye, hair growth Agent. Among these, the conditioner, hair conditioner, repair agent, styling agent, or hair cleanser are preferred, and the conditioner, hair conditioner, or repair agent is more preferred. The dosage form of the hair cosmetics is not particularly limited, and for example, it can be made into any dosage form such as liquid, foam, paste, paste, solid shape, and powder. From the viewpoint of the spreadability of hair, it is preferably made into a liquid, paste or paste form, and more preferably made into a liquid or paste form. In addition, the hair cosmetic of the present invention may be diluted with water according to the usage form and used in the state of an aqueous solution.
