Definitions
- the present invention relates to stick-like oily cosmetics. More particularly, the present invention relates to a stick-like oily cosmetic that can be suitably used for foundation, concealer, tick, eyeshadow, sunscreen and the like.
- Stick-type oily cosmetics generally contain components such as wax and oil.
- a stick-type oily cosmetic that can give luster to the skin and maintain a moist feeling and cosmetic effect (A) 0.5 to 5.0% by mass of an amino acid derivative, (B) an alkyl group having a fluorine atom and a poly A stick-type oily cosmetic containing 0.1 to 30.0% by mass of silicone containing an oxyalkylene group, (C) 7.0 to 12.0% by mass of wax, and (D) 20.0 to 70.0% isostearate A fee has been proposed (see, for example, Patent Document 1).
- the present invention has been made in view of the above-mentioned prior art, and achieves both the prevention of cracks from occurring in stick-shaped oily cosmetics and the prevention of stick-shaped oily cosmetics from adhering to sanitary masks and the like.
- An object of the present invention is to provide a stick-like oily cosmetic that can
- the present invention A stick-like oily cosmetic containing a mixture of hydrogenated polyisobutene with a degree of polymerization of 15 to 50, volatile oil and wax, wherein the content of hydrogenated polyisobutene with a degree of polymerization of 15 to 50 in the mixture is 2 to 30% by mass, a volatile oil content in the mixture is 45 to 85% by mass, and a wax content in the mixture is 10 to 35% by mass.
- the stick-shaped oily cosmetics which can make both the stick-shaped oily cosmetics hard to generate a crack and the stick-shaped oily cosmetics hard to adhere to a sanitary mask etc. are provided. be done.
- the stick-like oily cosmetic composition of the present invention is a stick-like oily cosmetic containing a mixture of hydrogenated polyisobutene having a degree of polymerization of 15 to 50, a volatile oil and a wax (hereinafter simply referred to as "mixture" for convenience).
- Cosmetics the content of hydrogenated polyisobutene having a polymerization degree of 15 to 50 in the mixture is 2 to 30% by mass
- the content of volatile oil in the mixture is 45 to 85% by mass
- One of the features of the present invention is that the content of wax in is 10 to 35% by mass. Since the stick-type oily cosmetic of the present invention has the above constituent elements, cracks are unlikely to occur, and excellent effects such as adhesion to sanitary masks and the like are difficult to achieve.
- Hydrogenated Polyisobutene has the formula (I):
- n is the degree of polymerization of hydrogenated polyisobutene and represents an integer of 15 to 50
- the degree of polymerization of the hydrogenated polyisobutene is 15 or more, preferably 18 or more, from the viewpoint of preventing the stick-like oily cosmetic from adhering to sanitary masks, etc., and prevents the stick-like oily cosmetic from cracking. 50 or less, preferably 46 or less, from the viewpoint of
- the viscosity of the hydrogenated polyisobutene at 25° C. is preferably 10,000 from the viewpoint of preventing the stick-like oily cosmetic from adhering to sanitary masks and the like and preventing the stick-like oily cosmetic from cracking. ⁇ 800,000 mPa ⁇ s, more preferably 20,000 to 600,000 mPa ⁇ s.
- a B-type viscometer manufactured by Tokimec Co., Ltd., product number: B8L was used, and rotor No. 1 was used. 4.
- the viscosity of the hydrogenated polyisobutene can be measured under the condition of 6 revolutions.
- Hydrogenated polyisobutene with a degree of polymerization of 15 to 50 can be easily obtained commercially.
- Examples of hydrogenated polyisobutene having a degree of polymerization of 15 to 50 include Uniqema, trade name: Prisorine (registered trademark) 3758; NOF Corporation, trade name: Pearlream (registered trademark) 18 and Pearlream. (registered trademark) 24, Pearl Ream (registered trademark) 46, etc., but the present invention is not limited only to such examples.
- the content of the hydrogenated polyisobutene in the mixture is 2% by mass or more, preferably 3% by mass or more, from the viewpoint of preventing the stick-like oily cosmetic from adhering to a sanitary mask or the like. From the viewpoint of preventing cracks from occurring and improving the usability of the stick-type oily cosmetic, the content is 30% by mass or less, preferably 28% by mass or less.
- Volatile Oil used in the present invention means an oil having a boiling point of 270° C. or less under 1 atmosphere.
- Volatile oils include, for example, cyclic silicone oils such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane and dodecamethylcyclohexasiloxane; branched chain silicone oils such as methyltrimethicone; n-decane, n-undecane, n-paraffinic hydrocarbon oils such as n-dodecane; isododecane, isodecane, isohexadecane, light liquid isoparaffin, isoparaffinic hydrocarbon oils such as hydrogenated polyisobutene other than hydrogenated polyisobutene having a degree of polymerization of 15 to 50; cyclodecane, Examples include hydrocarbon oils such as cyclic paraffinic hydrocarbon oils such as cyclododecane, but the present invention
