[Industrial applications]
TECHNICAL FIELD The present invention relates to an oily solid cosmetic, and more specifically, has a high makeup-preventing function (cosmetic holding function and color transfer preventing function) and a high shape retention, excellent feeling in use, and high-temperature stability and safety. It is intended to provide a novel oil-based solid cosmetic which is excellent in quality.
[0002]
[Prior art]
Conventionally, oil-based solid cosmetics are mainly composed of solid oil, semi-solid oil, liquid oil and colorant, and have various shapes and properties to obtain comfortable usability and feeling of use as cosmetics. Studies have been made on the formulation of oils and coloring agents having the following characteristics.
In order to improve the longevity of oily solid cosmetics, powders such as mica are blended in a high ratio to reduce bleeding and food due to aging caused by the liquid oil content, foods, clothes, etc. In order to improve the adhesiveness to the lips, there were those in which a solid oil component was blended in a high ratio, and those in which the ratio of the colorant was extremely increased. In addition, there is a type that uses a volatile silicone as disclosed in JP-A-61-65809 and volatilizes the volatile silicone after application to make the remaining components only a colorant and a resin component, thereby improving the cosmetic durability. .
[0003]
[Problems to be solved by the invention]
However, those which have a long-lasting effect by adjusting the colorant such as mica and the solid oil content as described above have a drawback that they are inferior in the feeling of use, which is an important factor as an oily solid cosmetic. As a cause thereof, the amount of the liquid oil was inevitably limited by blending the coloring agent such as mica and the solid oil in a high ratio.
In addition, those using volatile silicone are excellent in the function of preventing makeup collapse, but are not suitable for oily solid cosmetics. That is, there is a problem that there is no solid agent capable of simultaneously satisfying shape retention and feeling of use in a system containing volatile silicone. Specifically, when a solid oil is used as a solidifying agent for volatile silicone, a small amount does not form a solid, so it is necessary to mix a large amount of the solid oil. Was not smooth and had poor usability. Furthermore, candelilla wax, carnauba wax, etc., which contain a large amount of high molecular weight ester-based components, have poor compatibility with volatile silicones, so that it has been difficult to form a uniform system.
[0004]
[Means for Solving the Problems]
The present inventors, in view of the problems of the above-described oil-based solid cosmetic, in particular makeup protection, shape retention, the results of extensive research and ¥ those satisfying feeling like simultaneously, certain hydrocarbon It has been found that a compound containing hydrogen wax and volatile silicone as essential components is excellent in the function of preventing makeup collapse, shape retention, and feeling of use, and has completed the present invention.
[0005]
That is, the present invention relates to a component (A) and a component (B):
(A) Carbon fraction 28 to 3 which is a hydrocarbon fraction from candelilla wax
3 to 30% by weight of hydrocarbon wax
(B) 5 to 50% by weight of volatile silicone
(C) High melting point wax having a melting point of 85 to 105 ° C 3 to 30% by weight
The present invention relates to an oil-based solid cosmetic comprising:
[0006]
Hereinafter, the present invention will be described in detail.
The hydrocarbon wax having 28 to 33 carbon atoms, which is the hydrocarbon fraction from the candelilla wax of the component (A) used in the present invention, is obtained by extracting the candelilla wax with a solvent such as hexane. Can be. Candelilla wax is the only plant-based wax that contains these hydrocarbon waxes having 28 to 33 carbon atoms in an amount of about 40 to 50% by weight (hereinafter simply referred to as%).
[0007]
The hydrocarbon wax having 28 to 33 carbon atoms, which is a hydrocarbon fraction from the candelilla wax of the present invention, is blended with the oily solid cosmetic in an amount of 3 to 30%. Within this range, good usability and shape retention can be obtained. If it is less than 3%, sufficient shape retention cannot be obtained, and if it exceeds 30%, the hardness is remarkably increased and the usability is deteriorated, which is not preferable.
[0008]
Examples of the volatile silicone as the component (B) used in the present invention include dimethylpolysiloxane having a low molecular weight represented by the general formula (1) and octamethyl which is a cyclic silicone represented by the general formula (2) Cyclotetrasiloxane and decamethylcyclopentasiloxane are exemplified.
[0009]

n: an integer of 4 to 6
These volatile silicones of the present invention are blended with oily solid cosmetics in a range of 5 to 50%. Within this range, a good makeup holding function and high safety can be obtained. If it is less than 5%, the function of holding makeup cannot be obtained, and if it exceeds 50%, it is not preferable in terms of stability.
[0012]
Furthermore, by blending a high melting point wax having a melting point of 85 to 105 ° C. into the oily solid cosmetic, the stability at high temperatures can be further improved. The high melting point wax used in the present invention is not particularly limited as long as it has a melting point of 85 to 105 ° C. Particularly preferred high melting point waxes include microcrystalline wax, paraffin wax, Fischer-Tropsch wax, polyethylene wax, and polyethylene polypropylene copolymer. And 30 to 30 % . Within this range, sufficient solidified shape retention can be obtained, and a good feeling in use can be obtained. Depending on the raw material used, if it is less than 3%, sufficient high-temperature stability cannot be obtained, and if it exceeds 30%, the hardness is remarkably increased and the feeling of use is unpreferably deteriorated.
[0013]
The oily solid cosmetic of the present invention may be used in ordinary cosmetics in addition to the essential components described above, for example, squalane, liquid paraffin, liquid lanolin, liquid oils such as castor oil, semi-solids such as vaseline and lanolin. Shape oil, organic powder, pearlescent agent, white pigment, extender pigment, inorganic or organic coloring pigment, processed products of these powders (silicone, Teflon (registered trademark) treatment, etc.), acrylic or silicone resin, Dyes, surfactants, high molecular compounds, gelling agents, ultraviolet absorbers, antioxidants, preservatives, polyhydric alcohols, water, fragrances, cosmetic ingredients, microcapsules, etc., as long as the effects of the present invention are not impaired. It can be appropriately selected and used.
The oily solid cosmetic of the present invention includes lipstick, oily eye shadow, oily foundation, pencil eyeliner, pencil eyebrow and the like.
