JP5669423B2 - Foam cleansing cosmetic - Google Patents

Description

  The present invention relates to a foam-type cleansing cosmetic, and more specifically to a so-called aerosol type cleansing cosmetic in which foam is formed by a propellant.

  For removing oily makeup cosmetics, it is most effective to use foams of oily ingredients. However, since the oil component does not have foaming properties, it has been difficult to obtain a stable foam. By using various foaming aids, an aerosol type cleansing cosmetic that stably forms foam is obtained. Proposed. For example, Japanese Patent Application Laid-Open No. 07-277954 (Patent Document 1) discloses a foam aerosol composition using an oil component and a dextrin fatty acid ester as a foaming aid. Japanese Patent Application Laid-Open No. 2004-203847 (Patent Document 2) discloses a foamy aerosol cleansing cosmetic comprising a stock solution containing a sucrose fatty acid ester, a diglycerin fatty acid ester, and a liquid oil component, and a propellant. Japanese Patent Application Laid-Open No. 2010-24202 (Patent Document 3) discloses a foamy aerosol cleansing cosmetic containing a liquid oil composed of fats and oils and / or an ester oil and a diglycerin fatty acid ester having a hydroxyl group having a different ester residue. Is disclosed. JP-A-2006-347896 (Patent Document 4) discloses a foamy aerosol cleansing cosmetic containing polyglycerin alkyl ether and liquid oil.

  However, when foaming aids such as dextrin fatty acid esters and sucrose fatty acid esters are used as disclosed in Patent Documents 1 to 4, the formed foam has insufficient sustainability and immediately after being taken out by hand. In addition, although the viscosity did not decrease so as to be struck from the hand, the foam was crushed and formed into a paste at the time of application, and it was not possible to cleanse with the desired foam.

  On the other hand, JP-A-2009-286769 (Patent Document 5) discloses a foamy aerosol composition having a stable emulsification state and good foamability, in which inulin laurylcarbamate is blended as a surfactant. It is disclosed.

  However, inulin laurylcarbamate used in Patent Document 5 is used as an emulsifier, and the emulsifier improves the stability of a non-emulsifying foamable aerosol composition whose main component is an oil component. There is no suggestion.

  The present invention has been made in view of the above-mentioned background art, and an object thereof is to provide an aerosol-type foam cleansing cosmetic mainly composed of an oil component that has good foaming, stable foam, and excellent detergency. And

  The foam cleansing cosmetic of the present invention is mainly composed of a liquid oil that is a basic skeleton of oil-based cleansing, and has thickening (tribehenic acid / isostearic acid / eicosanedioic acid) glyceryl, and further diglycerin monolaurate and diester. Aerosol-type oily foam cleansing cosmetic containing a stock solution and propellant containing any one or more selected from the group consisting of glycerin monocapric acid ester and decaglycerin trilauric acid ester and alkyl carbamate inulin It is.

  According to the present invention, a foaming cleansing cosmetic having good foaming properties and excellent foam stability and cleanability is provided.

  The present invention is an aerosol-type foam cleansing cosmetic comprising a stock solution and a propellant. The stock solution according to the foam cleansing cosmetic composition of the present invention comprises liquid oil in an amount of 65% by mass to 95% by mass, and (tribehenic acid / isostearic acid / eicosanedioic acid) glyceryl in an amount of 0.01% by mass to 5% by mass. 2 or more and 30% by mass or less of one or two or more selected from the group consisting of diglycerin monolaurate, diglycerin monocaprate and decaglycerin trilaurate, and 0. 01 mass% or more and 2 mass% or less. In this specification, “%” and “part” mean “% by mass” and “part by mass”, respectively, unless otherwise specified.

  The liquid oil performs a cleansing function. In the present invention, the liquid oil is an oily component that is liquid at the time of foaming, specifically, an oily component that is liquid at 15 ° C., and is particularly limited as long as it is used as a known cleansing cosmetic. It is not something. The liquid oil may be derived from vegetable oils, animal oils, mineral oils, synthetic oils and the like, and oily components such as hydrocarbons, fatty acids, higher alcohols, silicones, esters and the like are used in addition to fats and oils. For example, avocado oil, camellia oil, turtle oil, macadamia nut oil, corn oil, mink oil, olive oil, rapeseed oil, egg yolk oil, sesame oil, persic oil, wheat germ oil, sasanqua oil, castor oil, flaxseed oil, safflower oil , Cottonseed oil, eno oil, soybean oil, peanut oil, tea seed oil, kaya oil, rice bran oil, cinnagari oil, Japanese kiri oil, jojoba oil, germ oil, palm oil, palm kernel oil, trioctanoic acid glycerin, triisopalmitic acid Triglycerides such as glycerin, fats and oils such as glyceryl tri-2-ethylhexanoate and cholesterol fatty acid esters, hydrocarbons such as liquid paraffin, squalene and squalane, cetyl isooctanoate, isopropyl myristate, hexyldecyl isostearate, diisopropyl adipate, sebatin Di-2-ethylhexyl acid , Cetyl lactate, diisostearyl malate, ethylene glycol di-2-ethylhexanoate, neopentyl glycol dicaprate, glycerin di-2-heptylundecanoate, glycerin tri-2-ethylhexanoate, tri-2-ethylhexane Synthetic ester oils such as trimethylolpropane triacid, trimethylolpropane triisostearate, pentane erythritol tetra-2-ethylhexanoate, cetyl octoate, isopropyl myristate, isopropyl palmitate, hexyl laurate, oleyl oleate, olein Decyl acid, octyldodecyl myristate, hexyl decyl dimethyloctanoate, diethyl phthalate, dibutyl phthalate, diglycerin tetraoleate, diglycerin diolate, diglycerin trioleate , Diglycerin tetraisostearate, diglycerin triisostearate, diglycerin diisostearate, triglycerin pentaoleate, triglycerin tetraoleate, triglycerin trioleate, triglycerin dioleate, triglycerin pentaisostearate, tri Fatty acid esters such as glycerin tetraisostearate, triglycerin triisostearate, triglycerin diisostearate, higher alcohols such as lauryl alcohol, oleyl alcohol, isostearyl alcohol, octyldodecanol, dimethylpolysiloxane, methylphenyl poly Chain polysiloxane such as siloxane, diphenylpolysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, Examples include silicone oils such as cyclic polysiloxanes such as decamethylcyclohexanesiloxane, higher fatty acids such as oleic acid and isostearic acid, or those obtained by subjecting the oil component to treatment such as hydrogenation and fractionation. One or more liquid oils are used.

  The blending amount of the liquid oil is 65% or more and 95% or less in the stock solution. When the blending amount is more than 95%, not only foam formation (foaming property) becomes insufficient, but also the feeling after use becomes extremely oily. Further, if the content of the oil component is less than 65%, sufficient detergency cannot be obtained.

  In the stock solution in the present invention, (tribehenic acid / isostearic acid / eicosanedioic acid) glyceryl is blended. The substance is an oligomeric ester of tribehenic acid and eicosanedioic acid, isostearic acid and glycerin, which increases the viscosity of the stock solution and facilitates foam formation as well as improving foam quality and enhancing foam stability. For example, a substance marketed under the trade name Nom Coat SG (Nisshin Oillio Group) is used.

  The compounding amount of the substance is 0.01% or more and 5% or less in the stock solution. If it is less than 0.01%, the viscosity of the undiluted solution does not sufficiently increase, and there is a strong possibility that bubbles will flow down when taken out by hand. On the other hand, if it exceeds 5%, the viscosity of the undiluted solution becomes too high and foaming becomes worse.

  The stock solution contains one or more selected from the group consisting of diglycerin monolaurate, diglycerin monocaprate, and decaglycerol trilaurate.

  These substances are used as foaming agents and have a function of foaming oily components by the action of the propellant. The blending amount of these substances is 2% or more and 30% or less in the stock solution. If it is less than 2%, foam formation is insufficient, and if it exceeds 30%, the persistence of the foam will be weakened, which is not preferable.

  Furthermore, 0.01% or more and 2% or less of inulin alkylcarbamate in the stock solution is added to the stock solution. Inulin alkylcarbamate is a compound that stabilizes emulsification by forming a steric barrier around oil droplets. In the present invention, the function of not only forming fine bubbles but also maintaining the generated bubbles stably. To play a role in improving the quality of foam produced. Also, the incorporation of inulin alkylcarbamate improves detergency. If the blending amount is less than 0.01%, these functions are not sufficiently exhibited, and even if blending more than 2%, further effects cannot be expected.

  Inulin alkylcarbamate can be synthesized by reacting inulin with alkyl isocyanate. Inulin is a kind of polysaccharide, in which D-fructofuranose is linked in a β2 → 1 bond, and fructose at the hemiacetal type end is linked to D-glucose and α-glucopyranoside. The alkyl group of the alkyl isocyanate may be either a straight chain or a branched chain, and those having about 2 to 18 carbon atoms are used, preferably inulin laurylcarbamate having 12 carbon atoms.

  As described above, in the present invention, (tribehenic acid / isostearic acid / eicosanedioic acid) glyceryl, diglycerol monolaurate, diglycerol monocaprate, and decaglycerol trilaurate are selected. One type or two or more types and inulin alkylcarbamate are used as foaming aids, and other foaming aids or surfactants such as dextrin fatty acid esters, dextrin fatty acid esters and sucrose fatty acid esters are used. Without any problem, good foaming property and stable foam formation are possible.

  However, in the cleansing cosmetic composition of the present invention, in addition to the above-mentioned essential components, as needed, common ingredients used in cleansing cosmetic compositions are used as optional components. For example, pH adjusters such as citric acid, phosphoric acid, sodium bicarbonate, polyethylene glycol, glycerin, 1,3-butylene glycol, erythritol, sorbitol, xylitol, maltitol, propylene glycol, dipropylene glycol, diglycerin, 1, Polyhydric alcohols such as 2-pentanediol, 1,2-hexanediol, 1,2-octanediol, moisturizing ingredients such as sodium pyrrolidonecarboxylate, lactic acid, sodium lactate, plant extract, guar gum, quince seed, carrageenan, Galactan, gum arabic, pectin, mannan, starch, xanthan gum, curdlan, methylcellulose, hydroxyethylcellulose, carboxymethylcellulose, methylhydroxypropylcellulose, chondroit Sulfuric acid, dermatan sulfate, glycogen, heparan sulfate, hyaluronic acid, sodium hyaluronate, tragacanth gum, keratan sulfate, chondroitin, mucoitin sulfate, hydroxyethyl guar gum, carboxymethyl guar gum, dextran, keratosulfate, locust bean gum, succinoglucan, caronic acid , Chitin, chitosan, carboxymethyl chitin, agar, polyvinyl alcohol, polyvinyl pyrrolidone, carboxyvinyl polymer, sodium polyacrylate, polyethylene glycol, bentonite, etc. Liquid lower alcohols, vitamin A or derivatives thereof, vitamin B6 hydrochloride, vitamin B6 tripalmitate, vitamin B6 dioctanoate, Min B2 or derivatives thereof, vitamin B such as vitamin B12, vitamin B15 or derivatives thereof, vitamin E such as α-tocopherol, β-tocopherol, γ-tocopherol, vitamin E acetate, vitamin D, vitamin H, pantothene Various vitamins such as acid, pantethine and pyrroloquinoline quinone, fragrances and the like can be used as long as the effects of the present invention are not impaired. Further, the cleansing agent of the present invention is a non-emulsifying cleansing agent and is usually a cosmetic that does not contain water. However, cosmetics such as moisture used for dissolving the above-mentioned additive components and moisture in raw materials, etc. Depending on the properties of the raw material components used in the material, a small amount, specifically 0.5% or less, and at most 1.0% or less may be contained.

  The stock solution is prepared by mixing and stirring the above components in a conventional manner. The prepared stock solution is filled in an aerosol container together with a propellant at a predetermined ratio to obtain the cleansing cosmetic of the present invention. A propellant will not be restrict | limited especially if it can be used for the aerosol of cosmetics. For example, hydrocarbons such as liquefied petroleum gas (LPG) mainly composed of propane, n-butane, i-butane, etc., ethers such as dimethyl ether, methyl ethyl ether, diethyl ether, carbon dioxide gas, nitrogen gas, oxygen gas Compressed gas such as These propellants may be used alone or in admixture of two or more, and the blending amount is 2% or more and 90% or less, preferably 3% or more, based on the total amount of the stock solution and the propellant. It is 70% or less, more preferably 5% or more and 20% or less.

  The foam cleansing cosmetic is well shaken and discharged as a foam by the action of a propellant, used for washing the skin such as a face wash, and then washed away with water. Further, after washing with the discharged foam, it is wiped off with cotton or the like.
