Description

  The present invention relates to a cleansing material for removing cosmetics such as makeup cosmetics and UV-proof cosmetics. More particularly, the present invention relates to a cleansing material that is familiar with makeup stains quickly, is easy to wash off, has a clean feel after washing, has an emollient feeling after washing, and maintains a moist feeling after washing.

  In modern society, cleansing materials are indispensable for removing makeup cosmetics and UV-proof cosmetics. When cleansing is inadequate, makeup cosmetics and UV-preventive cosmetics contain a large amount of oily components, inorganic pigments, etc., and therefore clog the skin pores and prevent metabolism. Further, since the cosmetic itself and sebum are oxidized and cause skin troubles, a cleansing material that effectively removes cosmetic dirt and sebum dirt is desired.

  Therefore, the cleansing material contains an oily component that is well-suited to the above-mentioned dirt, a surfactant for cleaning and preventing recontamination, and a moisturizing component that supplements moisture that may be lost by cleansing. . As the oil component, nonpolar oils such as hydrocarbons and silicones, and polar oils such as ester oils and triglycerides are used. For example, Patent Document 1 discloses a cleansing cosmetic containing light liquid isoparaffin. However, the cleansing cosmetic of Patent Document 1 does not have a sufficient emollient feeling after washing.

  On the other hand, non-ionic surfactants such as polyglycerin fatty acid esters and polyoxyethylene alkyl ethers and ionic surfactants such as acyl amino acid salts are used as surfactants, and sugars, polyhydric alcohols, Amino acids, water-soluble polymers and the like are used. As a cleansing agent using an oily component, a surfactant and a moisturizing component in combination, for example, Patent Document 2 discloses a liquid oil such as tri-2-ethylhexanoic acid glyceride, a hydrophilic nonionic surfactant having an HLB exceeding 9, A cleansing composition containing a branched fatty acid and water is disclosed. Patent Document 3 discloses an oily component such as isododecane, a nonionic surfactant of HLB8 or higher, and a water-soluble solvent such as 1,3-butylene glycol. And a cleansing composition containing water, Patent Document 4 contains liquid oil such as liquid paraffin, polyoxyethylene glycerin fatty acid ester, polyoxypropylene diglyceryl ether, polyhydric alcohol and the like. An oily cleansing fee is disclosed. However, the cleansing composition of Patent Document 2 may be difficult to wash away, and the clean feeling after washing off is not satisfactory. The cleansing composition of Patent Document 3 may become easy to dry after washing. The oily cleansing material of Patent Document 4 did not have a clean feel after washing.

  In view of the above-mentioned problems, the present invention provides a cleansing material that is familiar with makeup stains quickly, is easy to wash off, has a clean feel after washing, has an emollient feeling after washing, and maintains a moist feeling after washing. Objective.

  As a result of repeated researches by the present inventors in order to solve the above-mentioned problems, a specific paraffin mixture, a specific nonionic surfactant, and a specific dihydric alcohol are combined in a specific ratio to achieve the object. I got a cleansing fee.

That is, the present invention is a cleansing material comprising 1 to 50% by mass of the following component a, 3 to 60% by mass of component b, and 1 to 30% by mass of component c.
a. A paraffin mixture comprising isoparaffins having 12 to 16 carbon atoms, having a boiling range of 185 to 215 ° C. and a content of 2,2,4,6,6-pentamethylheptane of less than 10% by weight b. One or more nonionic surfactants selected from polyoxyethylene fatty acid glycerin and fatty acid polyoxyethylene glycerin c. Dihydric alcohol having 3 to 6 carbon atoms

  According to the cleansing material of the present invention, it is possible to obtain an effect that it quickly adapts to makeup stains, is easily washed away, has a clean feel after washing, has an emollient feeling after washing, and maintains a moist feeling after washing.

  Embodiments of the present invention will be described below. The cleansing material of the present invention contains the following a component, b component and c component. Hereinafter, each component will be described.

[Component a]
The component a used in the present invention is a mixture of paraffin (saturated hydrocarbon) containing isoparaffin (branched saturated hydrocarbon) having 12 to 16 carbon atoms, and further linear saturated carbonization having 12 to 16 carbon atoms. 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 point 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 after washing is not clean. 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. %. When the isododecane content in the mixture is 10% by mass or more, the emollient feeling after washing is weakened, and the moist feeling after washing is not maintained. Moreover, since the boiling point is lowered and the flash point is lowered, it is not preferable in terms of safety, and the odor becomes strong, so that use as a cosmetic raw material is restricted. 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, the number of theoretical plates showing the separation ability of the distillation column is preferably 10 or more when obtaining the paraffin mixture of component a. 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 component a, “Pearl Ream 3” manufactured by NOF Corporation 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%.

[Component b]
The component b used in the present invention is at least one nonionic surfactant selected from polyoxyethylene fatty acid glycerin and fatty acid polyoxyethylene glycerin. Polyoxyethylene fatty acid glycerin is a compound obtained by, for example, esterifying glycerin and a fatty acid and then adding ethylene oxide. Fatty acid polyoxyethylene glycerin is a compound obtained by, for example, adding ethylene oxide to glycerin and then esterifying it with a fatty acid.

  The fatty acid constituting the component b is preferably a saturated or unsaturated fatty acid having 6 to 22 carbon atoms, and more preferably a saturated or unsaturated fatty acid having 8 to 18 carbon atoms. For example, single fatty acids such as caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, oleic acid, and behenic acid, mixed fatty acids derived from animal and vegetable oils such as coconut oil fatty acid and beef tallow fatty acid, etc. Can be used. When the number of carbon atoms of the fatty acid is less than 6, the lipophilicity is low, so that the familiarity with the makeup stains is deteriorated and the cleansing power may be lowered, and an irritating odor may be generated. If the fatty acid has more than 22 carbon atoms, it may be difficult to obtain a clean feeling after washing.

  In any of polyoxyethylene fatty acid glycerin and fatty acid polyoxyethylene glycerin, the average added mole number of ethylene oxide per mole of glycerin is preferably 5 to 100, more preferably 5 to 70, and particularly preferably 5 to 50. is there. When the average number of added moles of ethylene oxide is less than 5, the hydrophilicity is low, so that the compatibility with water is deteriorated and it may be difficult to obtain a clean feeling after washing. On the other hand, when the average number of added moles exceeds 100, the lipophilicity is lowered, so that the familiarity with makeup stains is deteriorated and the cleansing power may be lowered.

Moreover, it is preferable that HLB of b component used for this invention is 10-18, More preferably, it is 11-16. The HLB used in the present invention is a value according to the following calculation formula of Griffin.
HLB = 20 (1-S / A), where S: saponification value of ester, A: acid value of fatty acid.
When the HLB is less than 10, the hydrophilicity is low, so the compatibility with water is poor, and it may be difficult to obtain a clean feeling after washing. On the other hand, when the HLB exceeds 18, the lipophilicity is lowered, so that the familiarity with the makeup stains is deteriorated and the cleansing power may be lowered.

Specifically, polyoxyethylene fatty acid glycerin is polyoxyethylene (7 mol) mono coconut oil fatty acid glycerin (HLB = 13.0), polyoxyethylene (8 mol) mono (capryl / capric acid) glycerin (HLB = 15. 0), polyoxyethylene (12 mol) glycerol monolaurate (HLB = 15.0), polyoxyethylene (20 mol) glycerol monooleate (HLB = 15.4), polyoxyethylene (30 mol) monococonut oil fatty acid Examples include glycerin (HLB value = 17.4).
Specific examples of fatty acid polyoxyethylene glycerin include polyisoethylene monoisostearate (8 mol) glycerin (HLB = 12.2), polyoxyethylene monoisostearate (20 mol) glycerin (HLB = 15.4), tri And polyoxyethylene isostearate (30 mol) glycerin (HLB = 12.3).
Among these, polyoxyethylene (7 mol) monococonut oil fatty acid glycerin (HLB = 13.0), polyoxyethylene (8 mol) mono is preferable from the viewpoint of ease of compatibility with makeup stains and a clean feeling after washing off. (Capryl / Capric acid) Glycerin (HLB = 15.0), Polyisoethylene monoisostearate (8 mol) Glycerin (HLB = 12.2).

[Component c]
The c component used in the present invention is a dihydric alcohol having 3 to 6 carbon atoms. Specific examples include propylene glycol, 1,3-butylene glycol, pentanediol, dipropylene glycol and the like. One or more of these dihydric alcohols can be used. Of these, 1,3-butylene glycol and dipropylene glycol are preferred because of the effect of maintaining a moist feeling after washing.

  In this invention, content of said a component is 1-50 mass% in a composition whole quantity, Preferably it is 1-30 mass%, More preferably, it is 2-20 mass%. If it is less than 1% by mass, familiarity with makeup stains is delayed, the feeling of cleanliness after washing is weak, the emollient feeling after washing is weakened, and the moist feeling after washing is not maintained. If it exceeds 50% by mass, it will be difficult to wash off, and the moist feeling after washing will not last.

  Content of said b component is 3-60 mass% in a composition whole quantity, Preferably it is 3-40 mass%, More preferably, it is 3-30 mass%. If it is less than 3% by mass, familiarity with the makeup stains will be delayed, it will be difficult to wash off, and the clean feeling after washing will be weak. If it exceeds 60% by mass, the emollient feeling after washing is not sufficient, and the moist feeling after washing is not maintained.

  Content of said c component is 1-30 mass% in the composition whole quantity, Preferably it is 2-20 mass%, More preferably, it is 3-15 mass%. If it is less than 1% by mass, familiarity with makeup stains will be delayed, making it difficult to wash away, and a moist feeling after washing will not last. When it exceeds 30% by mass, the refreshing feeling after washing is not sufficient.

The total content a + b + c of the a component, the b component and the c component can be appropriately adjusted according to the dosage form / use method of the cleansing material and the required cleansing performance. Usually, water is added as another additive or the balance. The cleansing material is prepared at 100% by mass. The total content a + b + c in the cleansing material is preferably 5 to 80% by mass, more preferably 5 to 60% by mass, from the effect of maintaining a moist feeling after washing away.
Additives commonly used in cosmetics can be further blended into the cleansing material of the present invention as long as the performance of the cleansing material of the present invention is not impaired.
