Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an oily cosmetic containing a solid dialkyl ketone and a liquid oil having an IOB value of 0 to 0.5 (excluding silicone oil). The present invention relates to an oil-based cosmetic composition which has excellent properties and is excellent in usability and feeling on skin and lips, adhesiveness and stability over time.

[0002]

2. Description of the Related Art Conventionally, oily cosmetics include waxes for maintaining shape, liquid oils and paste oils for sensory adjustment, organic and inorganic pigments for producing color tone, and pearl and lame agents for producing luster. Etc. In particular, waxes are indispensable raw materials for maintaining the shape, and hydrocarbons, waxes, hardened oils and fats, higher fatty acids, etc. have been widely used as the main ones.

[0003]

However, although waxes are excellent in that they solidify liquid oils of highly polar esters and retain their shape, they are not suitable for low polar oils such as hydrocarbons. It may be difficult to solidify or maintain the shape, especially when a large amount of low-polarity oil is mixed in the product, for example, in the case of stick-shaped cosmetics, the breaking load value is significantly reduced, and the like. In pasty or liquid products, phenomena such as separation of low-polarity oil with time may occur.

[0004]

Means for Solving the Problems As a result of intensive studies for solving the above-mentioned problems, the present inventors have found that by containing a solid dialkyl ketone and a low polar oil having a specific IOB value, the shape-retaining property is improved. The present invention has been completed based on the finding that it is excellent in smoothness, lightness, spreadability and spreadability, improved stickiness-free feeling, and good adhesion and stability over time. That is, the present invention provides an oily cosmetic containing a solid dialkyl ketone and a liquid oil having an IOB value of 0 to 0.5.
