Description

hair cosmetics

The present invention relates to a hair cosmetic.

Hair can be damaged by living environment (ultraviolet rays or heat generated by sunlight), daily hair care behaviors (friction caused by shampooing or combing), and chemical treatments (coloring, perming, etc.). If damaged hair is rubbed against each other, greater friction will be generated on the surface, resulting in tangles. "Hair tangles" become the cause of all stress in hair care practices. "Hair tangles" are perceived due to poor combability when washing hair with shampoo and other hair cleansers, and poor combability when washing hair after shampooing. As a method to untangle hair after shampooing, when using hair cosmetics such as conditioner or treatment, apply the hair cosmetics to the hair while using it Use your fingers to comb through the tangled area to fuse it, so that the lubricating ingredients spread over the surface of the hair and untangle the hair. In the prior art, in order to improve the combability or combability of hair, cationic surfactants, higher alcohols, polysiloxanes, etc. were blended into hair cosmetics such as conditioners or repair serums.

Patent Document 1 discloses a hair cosmetic using polyetheramine-modified polysiloxane and a cationic surfactant. It suppresses the dry feeling of hair in the water flow during washing, improves softness or smoothness, and can prevent washing-related problems. Damage caused by hair tangles. Patent Document 2 discloses a combination of amine-modified polysiloxane in a specific kinematic viscosity range, amino-polyether-modified polysiloxane, dimethylpolysiloxane in a specific kinematic viscosity range, and a specific Hair cosmetics with alkyl cations and specific higher alcohols can improve the moisture retention of hair and improve combability during use, thereby giving a soft and moist feeling, and preventing dryness under low humidity. Moisture. Furthermore, Patent Document 3 discloses that adhesive components on the hair are adsorbed by combining amino polyether co-modified polysiloxane and volatile polysiloxane with a specific structure in a hair cosmetic that is used after rinsing after applying to the hair. The amount is reduced, and the bulky adhesive components are less likely to adhere to the hair. As a result, the wet hair after treatment is easily spread out and the drying speed is increased.

The present invention relates to a hair cosmetic, which contains or is formulated with an amino polyether-modified polysiloxy (A) having a polyoxyalkylene structure in the side chain part, and a polyoxyalkylene group in the main chain part. The structure is made of amino polyether modified polysiloxane (B).

[Hair cosmetics] The hair cosmetic of the present invention is characterized in that it contains or is formulated with amino polyether-modified polysiloxane (A) having a polyoxyalkylene structure in the side chain portion (hereinafter also referred to as "ingredient (A)"). ”), and amino polyether-modified polysiloxane (B) having a polyoxyalkylene structure in the main chain part (hereinafter, also referred to as “component (B)”). The amine group in component (A) and component (B) may be any one of primary to tertiary amine groups. Moreover, the amine may be present in either the main chain part or the side chain part of the component (A) and the component (B), and it is preferably present in the side chain part. By containing or blending the above-mentioned component (A) and component (B) together, the hair cosmetic of the present invention can detangle the hair without having to comb the hair with hands when applied to the hair. Furthermore, it can increase the drying speed of the treated hair and provide smoothness to the hair during washing. Furthermore, "containing component (A) and component (B)" here also means "comprising component (A) and component (B)."

Regarding the hair cosmetics described in Patent Documents 1 to 3, although the smoothness, combability, and drying speed of the hair during use are improved, they do not reach the point where operations such as combing the hair by hand are not required. Spontaneously untangles hair. The present invention relates to a hair cosmetic. If it is applied to hair, it can untangle the hair without combing it through by hand, thereby increasing the drying speed of the treated hair and improving the hair quality during washing. Gives smoothness.

The present inventors discovered that a hair cosmetic containing or blending two types 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, tangles can be untangled without having to comb the hair with hands. In addition, the hair applied with this hair cosmetic dries quickly, and the hair has good smoothness when washed.

The reason why the hair cosmetic of the present invention exhibits the effects of the present invention due to the above-mentioned constitution is not yet clear, but it is presumed as follows. It is considered that it is important to reduce the frictional force acting between the hairs in order to achieve a state in which the tangles of hair generated during shampooing or the tangles of hair existing after shampooing are spontaneously undone. It is considered that although polysilicone is sometimes blended as an active ingredient in hair cosmetics, the use of component (B), which is an amino polyether-modified polysilicone with high water solubility, can reduce the risk of generation between hairs. The friction force acting on it shows the effect of untangling the hair. In addition, by using ingredient (A), the drying speed of hair treated with hair cosmetics can be increased, and smoothness can be imparted to hair during washing. Furthermore, the present inventors discovered that by using component (A) and component (B) together, hair can be detangled more effectively than when component (B) is prepared alone.

[Number 1]

(comb load measurement) Using Japanese straight hair, make a hair bundle for evaluation with a mass of 20 g, a length of 30 cm, and a width of 5.5 cm (the hair bundle is damaged due to bleaching treatment with the following bleaching agent). Wash the hair bundle with the following ordinary shampoo, comb through it with your hands to untangle it, and fully moisten it with warm water at 35 to 40°C. Apply ordinary shampoo to the hair strands again, clamp the ends and roots of the hair in the palms of your hands and rub them together in a circular motion to tangle the hair and create foam. Wash the hair bundle with warm water for 30 seconds without combing it through with your hands, squeeze out the water with your hands, and then immerse it in 1 L of the hair cosmetic of each example added to a 1 L beaker. Vibrate the hair bundle about 5 times in the beaker and then lift it up. When the moisture content of the hair bundle reaches 20 g, measure the load applied to the hair bundle when it is first combed with a comb according to the following points. The above-mentioned hair bundle was set on a combing force measuring device ("KOT-0303" manufactured by Utunomiya Seiki Co., Ltd.), and two combs (rib combs, 2.5 cm in width and 9.0 cm in length were used to comb the hair lengthwise at intervals of 5 mm). Arrange 5 rows of comb teeth (pins) with a diameter of 1 mm and a length of 2 cm) and set it so that the uppermost part of the hair bundle is clamped, and measure the load (gf) exerted when the comb reaches the tip of the hair. The load is measured in units of 1.5 mm for a hair bundle with a length of 30 cm, and the maximum value of a total of 200 measured values is used as the combing load. The smaller the value of the combing load is, the higher the effect of spontaneously untangled hair is. In addition, when purified water is used instead of hair cosmetics, the detangling load is the upper limit of measurement of 2055 gf.
