2. Description of the Related Art Conventionally, many oily solid cosmetics have been proposed and used, but most of them have drawbacks in usability such as oiliness and stickiness and strong oil film feeling.
Also in the finish, there is a problem that gloss due to the oil component in the oily cosmetics comes out, and it is not satisfactory in makeup such as swelling and bleeding after application. There is a method of blending a large amount of powder in order to improve this defect, but the spread at the time of application becomes heavy, the usability is reduced, and the viscosity at the time of heating and melting is increased, so that the melt filling property is reduced. However, there is a problem that it is not possible to form a cake having a smooth surface, a rod shape, or a three-dimensional shape by ordinary casting, or a stick is broken or a shape is damaged during use or transportation. there were. In particular, when a pearlescent pigment such as titanium mica is blended in order to enhance the makeup effect, there is a remarkable decrease in the melt filling property.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a resin composition which does not decrease the usability such as spreading at the time of coating, and has a melt filling property.

These powders may be used alone or in combination of two or more, and are subjected to a surface treatment by a known method using a fluorine compound, a silicone compound, a metal soap, a surfactant, a polymer, or the like. May be done.

[0006] The compounding amount of the powder component is 50 to 90%, preferably 55 to 85% in the oily solid cosmetic of the present invention. If it is less than 50%, a powdery feeling cannot be obtained, and if it is more than 90%, the melt-filling property deteriorates, which is not preferable. Among these powders, pearlescent pigments,
It is particularly preferable to add 30 to 60% in order to enhance the makeup effect.

[0007] The sucrose fatty acid ester in the oily component used in the present invention has an HLB value of 12 or less. As long as the sucrose fatty acid ester is included in this range, a mixture of a plurality of types of sucrose fatty acid esters can be used. Good. If the HLB value exceeds 12, the solubility in the oily base is insufficient, and it is difficult to obtain sufficient melt filling properties and shape retention, which is not preferred. The ratio of the sucrose fatty acid ester blended in the oil component is preferably 0.1 to 40%, more preferably 1.0 to 35%, based on the total oil component. When the ratio of the lipophilic sucrose fatty acid ester is less than 0.1%, sufficient fluidity cannot be obtained at the time of melt filling, and when the ratio of the sucrose fatty acid ester exceeds 40%, the ratio of other solid oils decreases, In some cases, sufficient shape retention cannot be obtained.

[0008] The solid oil in the oily component used in the present invention is not particularly limited as long as it is generally used for cosmetics, and hydrocarbons, waxes, oils and fats, fatty acids, higher alcohols , Esters, hardened oils, silicone waxes, fluorine waxes and the like can be used as appropriate. More specifically, for example, polyethylene wax, paraffin wax, ceresin wax, microcrystalline wax, ethylene propylene copolymer, carnauba wax, candelilla wax, beeswax, rice wax, hydrogenated castor oil, stearic acid, palmitic acid, 12-hydroxystearin Examples include acids, cetyl alcohol, stearyl alcohol, hydrogenated jojoba oil, and stearyl-modified polysiloxane. The ratio of the solid oil containing the sucrose fatty acid ester is 15 to
60%, preferably 25-55%. If this ratio is less than 15%, sufficient shape retention cannot be obtained, and 60%
If the amount exceeds the above range, sufficient fluidity cannot be obtained at the time of melt filling, and the spread during use is undesirably reduced.

As the oily component other than the solid oil in the oily component, any liquid or semi-solid oil commonly used in cosmetics can be used. Regarding liquid and semi-solid oils, volatile oils are also included in liquid oils regardless of the origin of animal oils, vegetable oils, synthetic oils and the like. Specific examples include hydrocarbons, lanolin and lanolin derivatives, oils and fats, hardened oils, ester oils, fatty acids, higher alcohols, silicone oils, fluorine-based oils, and the like. For example, petrolatum, liquid paraffin, squalane, polyisobutylene, polybutene, lanolin, castor oil, olive oil,
