Description

  Even when applied to damaged hair, the present invention does not become sticky after drying, is smooth and smooth to the finger, gives the hair a firmness, firmness, and finishes with glossy and coherent hair The present invention relates to a hair cosmetic that can be used.

  Hair is damaged daily by exposure to ultraviolet rays, chemicals in the atmosphere, heat from a dryer or iron, or friction from shampoo or brushing, stress in social life, etc. The unity becomes worse or the luster is lost. Therefore, by using hair cosmetics such as hair conditioners, hair treatments, hair rinses, hair packs, hair milk, hair creams, etc., it improves the condition of fingering and cohesion, and exerts conditioning effects such as imparting gloss, firmness, and elasticity, I am trying to keep my hair healthy.

  Usually, in the hair cosmetics, in addition to the cationic surfactant that smoothes the hair surface, oily components such as hydrocarbons, ester oils, animal and vegetable oils, and highly polymerized silicones are appropriately blended. Oily components such as hydrocarbons, ester oils and animal and vegetable oils can soften the hair and give it a moist feeling, but tend to be sticky when finished and give an unnatural luster. Highly polymerized silicone has low surface tension, excellent lubricity, and can impart good fingering and gloss to hair, but tends to reduce hair volume and prevent firmness and firmness. . For this reason, various hair cosmetics combining an oily component and a highly polymerized silicone have been proposed, but satisfactory products have not yet been obtained, which is sufficient in terms of lack of stickiness, gloss, firmness and firmness. It was not demonstrated.

  On the other hand, with the increase in fashionable thinking in recent years, damage to hair has become serious along with an increase in opportunities for daily decoloring treatment such as hair coloring and bleaching and redox treatment such as perm. In hair that has been decolorized or oxidized / reduced, intercellular lipids and proteins are oxidized and denatured, gradually flowing out during shampooing and other hair washing, the cuticle is partially peeled off, and the hydrophilicity of part of the hair surface increases. . As a result, the hair tends to be charged by friction between the hairs during drying, and the touch is remarkably impaired. For this reason, it is necessary to improve the feel by applying an oily component to the hair.However, the hair with increased hydrophilicity is less compatible with the oily component and the highly polymerized silicone, and provides a sufficient feeling of conditioning such as moist feeling, fingering and cohesion. There was also a problem that it was not possible.

  Therefore, for the purpose of obtaining a high conditioning effect on damaged hair, it is a type of hair cosmetic that does not wash off after being applied to the hair, and is a combination of solid oil, ester oil and silicone oil containing highly polymerized silicone. Hair cosmetics (Patent Document 1) have been proposed. However, since this hair cosmetic composition is highly blended with highly polymerized silicone and an oily component, it feels heavy when applied, and sticky when finished. Therefore, for the purpose of reducing stickiness, a method of combining highly polymerized silicone and an oil component with low molecular silicone or volatile hydrocarbon oil has been proposed (Patent Documents 2 to 4).

  Specifically, Patent Document 2 proposes a hair cosmetic that combines volatile silicone, highly polymerized silicone, and vegetable oil. However, although it gave good fingering to the hair and was not sticky, it was finished with a light and light touch, so that it was not moist and sufficient tension and firmness could not be obtained.

  Therefore, oily hair cosmetics combining volatile hydrocarbon oil, dimethiconol, and vegetable oil (Patent Document 3) and hair cosmetics combining volatile hydrocarbon oil, nonvolatile silicone oil, and vegetable oil (Patent Document 4) are proposed. Has been. However, although there was no stickiness and the finish was coherent, the hair was still crisp and still lacked a moist feeling, and the gloss was not sufficiently imparted, and it was not possible to obtain better fingering. Furthermore, since the hydrocarbon oil having a high content of 2,2,4,6,6-pentamethylheptane (isododecane) has an odor and may cause skin trouble, these hair cosmetics are satisfactory. It was not something that could be used.

Is a hair cosmetic characterized by

  According to the hair cosmetic composition of the present invention, even when applied to damaged hair, it does not become sticky after drying, is smooth and smooth to the fingers, gives the hair a firmness and firmness, The effect of finishing into coherent hair is obtained.

  Embodiments of the present invention will be described below. The hair cosmetic composition of the present invention contains the following component (A), component (B) and component (C). Hereinafter, each component will be described.

[Component (A)]
Component (A) used in the present invention is a mixture of paraffins (saturated hydrocarbons) containing isoparaffin carbon number of 12 (branched saturated hydrocarbons), furthermore, linear saturated 12 to 16 carbon atoms carbide May contain hydrogen. The paraffin mixture of the present invention contains hydrocarbons other than saturated hydrocarbons having 12 to 16 carbon atoms, such as cyclic saturated hydrocarbons and unsaturated hydrocarbons, to the extent that they do not contradict the purpose of the present invention. May be.

  The paraffin mixture of component (A) used in the present invention has a boiling range of 185 to 215 ° C, preferably 186 to 210 ° C. When the boiling point of the paraffin mixture is less than 185 ° C., the flash point becomes low, which is not preferable in terms of safety. When the boiling point exceeds 215 ° C., the volatility decreases and the oil tends to remain, so that the feeling of use when applied to the skin and hair is inferior. The boiling point can be measured by a distillation test according to JIS K2254.

  The paraffin mixture used in the present invention has a content of 2, 2, 4, 6, 6-pentamethylheptane (isododecane) of less than 10% by mass, preferably less than 8% by mass, and more preferably 5% by mass. %. If the content of isododecane in the mixture is 10% by mass or more, the boiling point is lowered and the flash point is lowered, which is not preferable in terms of safety, and the odor becomes strong and the feeling of use on the skin and hair is lowered. Use as raw materials is limited. Specifically, the paraffin mixture used in the present invention preferably has a flash point in the range of 61 to 70 ° C., preferably 62 to 67 ° C. in a sealing test according to JIS K2265, in terms of safety and odor. . For example, commercially available isododecane (2,2,4,6,6-pentamethylheptane content of 95% by mass or more) has a boiling point as low as 177 ° C. and a flash point of about 48 ° C., so care must be taken when handling fire. And strong odor. On the other hand, when the flash point exceeds 70 ° C., the drying property is deteriorated and the feel may be heavy.

The paraffin mixture used for this invention can be manufactured through the process containing the following processes 1-4, for example.
Step 1 (polymerization reaction): The paraffin mixture used in the present invention is a normal and iso-butene (co) polymer and is a C4 fraction in the fraction obtained by cracking of naphtha. It is obtained by polymerizing a mixed gas of butene and 2-butenes (cis-2-butene and trans-2-butene) by a known method. The composition ratio of isobutene, 1-butene and 2-butenes in this mixed gas is in the range of (isobutene / 1-butene / 2-butenes) = (15-80 / 10-40 / 10-60) by mass ratio. More preferably (15 to 70/15 to 40/15 to 60), particularly preferably (15 to 60/15 to 40/15 to 40), and particularly preferably (20 to 50/18 to 25 /). 18 to 40), more preferably (20 to 33/18 to 25/18 to 25). The mixed gas may contain isobutane or n-butane gas as an inert gas.

  The polymerization reaction of the C4 fraction containing isobutene is usually carried out at 40 to 120 ° C. using aluminum chloride, acidic ion exchange resin, sulfuric acid, boron fluoride and a complex thereof as a catalyst. It is also possible to control the polymerization reaction by adding a base to the catalyst.

  Step 2 (Hydrogenation reaction): Most of the polymer obtained in Step 1 has a double bond remaining at the terminal, and thus it is desirable to stabilize it as a hydride by hydrogenation reaction. The hydrogenation reaction is carried out by an ordinary method, and hydrogenation catalyst such as nickel or palladium is used for the polymer, and hydrogen is brought into contact with the reactor at a high temperature and high pressure in a fixed bed and fluidized bed type reactor. The degree of hydrogenation for obtaining the paraffin mixture used in the present invention is preferably an iodine value of 10 or less, more preferably 1 or less, and still more preferably 0.1 or less.

  Step 3 (adsorption treatment): Since the paraffin mixture obtained in step 2 may be mixed with trace metal compounds that cause coloring and odor, the paraffin mixture is adsorbed for the purpose of suppressing coloring and odor. It is desirable to perform adsorption treatment with an agent.

  As the adsorbent, inorganic and organic adsorbents are used. For example, clay, kaolin, talc, calcium carbonate, diatomaceous earth, zeolite, bentonite, acid clay, activated clay, vermiculite, silica gel, molecular sieve, and activated carbon are used. In particular, activated clay and clay are effective. These adsorbents can be used alone or in combination of two or more. The particle size of the adsorbent to be used is not particularly limited. However, when one kind of adsorbent is used, it is preferable to combine two or more adsorbents having different particle sizes. The combination of adsorbents is appropriately selected according to the dispersion of pressure in the column packed with the adsorbent and efficient processing. When two or more kinds of adsorbents are used, it is more effective in terms of production to pack 50 to 80% by volume of the smallest particle size with respect to the column volume.

  Step 4 (adsorption treatment): In the present invention, unreacted gas and high-boiling components having 20 or more carbon atoms are removed from the reaction product, and 2,2,4,6,6-pentamethylheptane is made less than 10% by mass. Therefore, it is desirable to purify by a general distillation method. Specifically, a simple distillation method, a continuous distillation method, a steam distillation method, a thin film distillation method, and the like can be combined. In addition, as for the theoretical plate number which shows the separation power of a distillation column, when obtaining the paraffin mixture of (A) component, 10 or more steps are desirable. Moreover, the boiling point range and flash point of the paraffin mixture can be adjusted by appropriately setting the distillation rate by distillation. For example, it is 15% by mass or more, preferably 25% by mass or more, preferably 40% by mass or less, and more preferably 35% by mass or less, with respect to the charged amount before performing vacuum distillation.

  As a specific product of the component (A), NOF Corporation "Pearl Ream 3" may be mentioned. “Pearl Ream 3” is a paraffin mixture containing isoparaffin having 12 carbon atoms, has a boiling range of 185 to 215 ° C., a flash point of 64 ° C., and an isododecane content of 0.4 mass%.

[(B) component]
The component (B) used in the present invention is silicone or a silicone derivative. Silicone means dimethylpolysiloxane, and the silicone derivative is a modified group such as an amino group, an alkyl group, a polyether group, or a cationic group in the dimethylpolysiloxane skeleton. It means various modified silicones introduced with. Hereinafter, silicone or silicone derivatives are collectively referred to as silicone compounds.

  The silicone compound is a silicone or a silicone derivative having an average degree of polymerization of 1000 to 5000, preferably a silicone or a silicone derivative having an average degree of polymerization of 2000 to 5000, from the viewpoint of improving the fingering of the hair during drying. If the average degree of polymerization is less than 1000, sufficient fingering may not be obtained. On the other hand, if the average degree of polymerization exceeds 5,000, sufficient tension and stiffness may not be obtained, and compatibility with the oil component may be deteriorated, so that sufficient stability over time may not be obtained. One type selected from these silicone compounds may be used, or two or more types may be used in combination.

  In general, these average degree of polymerization silicone compounds are difficult to use as they are because of their high viscosity and low workability (handling properties). Therefore, those diluted with linear or cyclic silicone or hydrocarbon oil having a polymerization degree of 3 to 100 are usually used. Specific examples of such silicone compounds include “KF-8020” and “KF-9028” manufactured by Shin-Etsu Chemical Co., Ltd.

* 8 "SIMULGEL EG" (manufactured by SEPPIC) (SIMULGEL EG composition: (sodium acrylate / acryloyldimethyltaurine sodium) copolymer: 37.5%, isohexadecane: 22.5%, polysorbate 80: 7.5%, Water: 32.5%)

  From the results of Examples 6 to 10, all of the hair cosmetics of the present invention did not become sticky after drying even when applied to damaged hair, and were smooth and smooth to the fingers. It can be seen that it gives a moist feeling and, further, produces an effect of finishing the hair with gloss and cohesion.

  On the other hand, in Comparative Examples 6-9, sufficient performance is not obtained. That is, in Comparative Example 6, since the mass ratio (A) / (B + C) is below the lower limit specified in the present invention, the hair is sticky and insufficient for fingering and firmness. In Comparative Example 7, since the component (A) is not blended, the hair is sticky and is insufficient in terms of finger feeling, moist feeling, gloss, and unity. In Comparative Example 8, since the content of the component (B) exceeds the upper limit specified in the present invention, the hair is sticky, and the firmness, firmness, moist feeling, and gloss are insufficient. In Comparative Example 9, a paraffin mixture whose boiling range and isododecane are outside the scope of the present invention is blended instead of the component (A), and different from the component (C) instead of the component (C). Since the beeswax is blended, the hair is sticky, and it is insufficient in terms of finger feeling, moist feeling, gloss, and unity.
