Description

  The present invention relates to an oily cosmetic containing a high molecular weight 1-butene polymer and a specific hydrocarbon oil, and more specifically, by blending a high molecular weight 1-butene polymer while having a low melting point, The present invention provides an oily cosmetic having both gloss and non-stickiness, high transparency, good adhesion to the skin, and excellent cosmetic film uniformity and makeup effect sustainability.

Conventionally, in oily cosmetics, methods of using heavy liquid isoparaffin and a specific gelling agent (for example, Patent Documents 1 and 2) have been studied in order to improve transparency, gloss, and makeup sustainability. However, these technologies can provide transparency and makeup sustainability, but the characteristics of the formulated oil agent are directly reflected in the feeling of use, so increasing the blending amount of heavy fluid isoparaffin to obtain a gloss It has been difficult to achieve a balance between non-stickiness and gloss, such that stickiness occurs and gloss is lost when trying to eliminate stickiness.
On the other hand, as a technique for obtaining a gloss, a method using a resin component having a film property such as trimethylsiloxysilicic acid (for example, Patent Documents 3 and 4) is also disclosed.

  However, with the conventional technology using oil agents and resin components, a glossy feeling is obtained, but due to compatibility problems with other oily components, there are difficulties in the transparency and uniformity of the decorative film, The feeling of use such as stickiness and film feeling was not satisfactory. In addition, when there is stickiness, the non-stickiness is an important quality in cosmetics, such as the spread at the time of application becomes heavier, the discomfort after application and secondary adhesion to clothes, etc. occur. For this reason, it has been desired to develop an oily cosmetic material having both glossiness and non-stickiness, high transparency, good adhesion to the skin, and excellent uniformity of the cosmetic film and durability of the cosmetic effect.

  In view of the above situation, the inventor has conducted intensive research and has focused on a 1-butene polymer that has not been used in cosmetics and is solid at room temperature, and has been identified as a high molecular weight 1-butene polymer. By using this hydrocarbon oil in combination, it realizes an oily cosmetic with good compatibility and excellent uniformity, has both gloss and non-stickiness, high transparency, good adhesion to the skin, and a cosmetic film The present invention has been completed by finding that an oily cosmetic material having excellent uniformity and makeup effect durability can be provided.
