Description

  The present invention relates to a non-solid lip cosmetic, and more particularly to a non-solid oily cosmetic that has no stickiness, is excellent in transparency upon application, imparts gloss, and has a long-lasting makeup.

Oily cosmetics are solid fats such as candelilla wax, liquid oils such as hydrocarbons, and pigments, etc., if necessary. From the viewpoint of affinity with the skin, etc., mainly lipstick, eye shadow, eyeliner and oily Widely used in makeup products such as foundations. There are various dosage forms such as solid, liquid, paste, and emulsion. Although it is required to have good cosmetic properties, sensory characteristics such as spreading and sticking, and storage stability, in recent years, it has been required to be even more moist and transparent (transparency). .
Of these, non-solid lip cosmetics such as liquids, pastes, and emulsions are superior to solid lip cosmetics in terms of maintaining a moist and moist feeling, and they are filled in brush pen containers and tube containers. It is also an advantage that it can be used.

  For example, liquid emulsified lip cosmetics containing dextrin fatty acid ester, hydrogenated polybutene, maltitol, liquid oily substance and water described in Patent Document 1 are known as liquid non-solid cosmetics. Good storage stability, good stretch, smooth and moist feel, gloss, no bleed, kinks, movement, close contact with lips It is said that water retention is also good. However, the transparency, the gloss after being applied to the lips and the persistence of the moist feeling are insufficient.

  Non-solid lip cosmetics that have good gloss, non-stickiness, and long-lasting gloss when applied, and have a moist feeling when applied and excellent durability, such as dextrin fatty acid ester and heavy liquid isoparaffin, which are liquid at room temperature. Although there is a non-solid non-aqueous oily cosmetic containing an oil component (Patent Document 2), stickiness occurs in a system in which the amount of heavy liquid isoparaffin is increased in order to improve the long-lasting makeup and gloss at the time of application. The current situation is that there is a problem.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a non-solid oily cosmetic that has no stickiness, is excellent in transparency and gloss at the time of application, and has excellent makeup.

  As a result of intensive studies to solve the above-mentioned object, the present invention has been found that the intended object can be achieved if a high-viscosity oil component and a specific semi-solid oil component are blended, and the present invention has been completed. .

  That is, the present invention contains a high-viscosity oil component of 25% by mass or more and a semi-solid oil component having an IOB value of 0.3 to 0.6, and the high-viscosity oil component / semi-solid oil component is 100: 1 to 1: 1 ( It is a non-solid lip cosmetic characterized by having a mass ratio).

  Here, IOB (Inorganic Organic Balance) means an inorganic value / organic value, and is based on an organic conceptual diagram of Satoshi Fujita (Satoshi Fujita, Masami Akatsuka, Systematic Organic Qualitative Analysis (mixture) 1974, Published by Kyoritsu Publishing). It represents the polarity of the organic compound. The higher the value, the higher the polarity and the water becomes ∞.

  The non-solid oily cosmetic of the present invention has no stickiness, is excellent in transparency and gloss at the time of application, and long-lasting makeup.

The best mode of the present invention will be described below.
(High viscosity oil)
The high-viscosity oil used in the present invention refers to one having a viscosity at 30 ° C. of 1000 cps or more, preferably 8000 to 500,000 cps. Viscosity here refers to the value measured on BL viscometer rotor No. 3, measuring conditions of 12 rpm. If an oil whose viscosity is too low is used, the makeup lasting time is insufficient.

Such high viscosity oils include diisostearyl malate, dipentaerythritol monoisostearate, sucrose tetraisostearate, diglycerin diisostearate, triglycerin diisostearate, decaglycerin decaisostearate. Isostearic acid esters such as isostearic acid ester of polyglycerol such as rate, hydrogenated products of copolymer of isobutene and n-butene, heavy fluid isoparaffins such as polybutene, high degree of polymerization of dimethylpolysiloxane and cross-linking Preferred examples include high-viscosity silicones such as those having a high degree of polymerization of type methylpolysiloxane or methylphenylpolysiloxane. These can contain only the seed | species, and can also contain it in combination of 2 or more type. Among these, heavy liquid isoparaffin and diisostearyl malate are preferable, and heavy liquid isoparaffin is particularly preferable.
The heavy liquid isoparaffin is preferably a polybutene having an average molecular weight of 500 to 4500, preferably 1000 to 3500, and a viscosity of 15,000 to 500,000 cps at 30 ° C. Moreover, diisostearyl malate has an average molecular weight of 600 to 800 and a viscosity of 1200 to 2500 cps at 30 ° C.

  In the non-solid lip cosmetic of the present invention, the blending amount of the high-viscosity oil must be 25% by mass or more in total with respect to the total amount of the cosmetic, and the upper limit is preferably 80% by mass. A more preferable blending amount of the high viscosity oil component is 25 to 60% by mass. If the high-viscosity oil content is less than 25% by mass, the gloss at the time of application is lacking, and the cosmetic durability tends to be inferior.

(Semi-solid oil)
The semi-solid oil used in the present invention has an IOB value of 0.3 to 0.6. When the IOB value is less than 0.3, the transparency at the time of coating becomes inferior. By using a semi-solid oil, the stickiness at the time of application is suppressed, and the cosmetic durability is improved.
The semi-solid oil component is an oil agent that has a melting point at a temperature exceeding the range of room temperature (15 to 25 ° C.) and that is not completely solidified within this range, and is distinguished from liquid oil and solid fat. The semi-solid oil component preferably has a card meter 800 g load, 5.6Φ, a hardness at 25 ° C. of 5 to 100, and a melting point of 30 to 60 ° C.

  Specifically, lanolin, trilanoline fatty acid glyceryl, soft lanolin fatty acid, branched or hydroxylated fatty acid cholesteryl, dipentaerythritol fatty acid ester (such as dipentaerythritol hexaoxystearate), isostearic acid hydrogenated castor oil, monohydroxystearic acid Hydrogenated castor oil, tri (capryl / caprin / myristin / stearic acid) glyceride, myristyl lactate, dimerlinoleic acid hydrogenated castor oil, dimerlinoleic acid (phytorteryl / isostearyl / cetyl / stearyl / behenyl), phytosteryl oleate, Examples include tetra (behenic acid / benzoic acid / ethylhexanoic acid) pentaerythrityl, hexahydroxystearic acid dipentaerythrityl, and the like, and these can be used alone or in combination.

  Particularly preferred as the semi-solid oil is pentaerythritol benzoate represented by the following general formula (1).

(In the formula, R ¹ and R ² represent a hydrogen atom or a linear or branched fatty acid residue or benzoic acid residue having 1 to 24 carbon atoms.)

Examples of such pentaerythritol benzoate include tetra (behenic acid / benzoic acid / ethylhexanoic acid) pentaerythrityl. In particular, R ¹ is a behenic acid residue and R ² is a 2-ethylhexanoic acid residue in the pentaerythritol benzoate represented by the general formula (1).

  The above pentaerythritol benzoate can be produced by a general synthesis method. For example, pentaerythritol, benzoic acid, linear or branched fatty acid is placed in a suitable reaction vessel (the order of addition is not particularly limited), and the reaction is preferably performed in the presence or absence of an acid, alkali, or other metal catalyst. It can be produced by carrying out the reaction in an inert organic solvent and / or gas while removing water by-produced at 150 to 250 ° C. for several hours to about 30 hours.

  The blending amount of the semi-solid oil used in the present invention is such that the high-viscosity oil / semi-solid oil is 100: 1 to 1: 1 (mass ratio), more preferably the high-viscosity oil / semi-solid oil. = 15: 1 to 2: 1 (mass ratio). If the semi-solid oil content is too high, it becomes inferior in gloss at the time of application, and if it is too low, stickiness at the time of application cannot be suppressed. A preferable blending amount of the semi-solid oil is 1 to 30% by mass, and more preferably 5 to 20% by mass.

  In this invention, it is preferable not to contain a wax, and when it is included, it is preferable that it is 0.1 mass% or less. When more wax is added, stickiness at the time of application can be suppressed, but the transparency tends to be impaired.

  The non-solid lip cosmetic of the present invention can contain a liquid oil at room temperature other than the above. The oily component that is liquid at room temperature is not particularly limited, and any oily component that can be used for cosmetics, quasi drugs, pharmaceuticals, and the like can be used without any problem. For example, hydrocarbons such as liquid paraffin and squalane, liquid synthetic ester oils (for example, tricapryl glycerine caprate, octyldodecyl myristate, isopropyl myristate, 2-ethylhexanoic acid triglyceride, hydroxyethyl stearate 2-ethylhexyl, Cetyl isooctanoate, etc.), vegetable oils (eg olive oil, macadamia nut oil, sesame oil, safflower oil, jojoba oil, soybean oil, camellia oil, etc.), liquid higher alcohols (eg octyldodecanol, oleyl alcohol, isostearyl alcohol) Etc.), liquid higher fatty acids (for example, isostearic acid, linoleic acid, etc.), silicone oil (for example, dimethylpolysiloxane, methylphenylpolysiloxane, etc.) It can be.
