Description

  The present invention relates to a lip cosmetic.

  In order to prevent lipstick color transfer, cosmetics combining a fluorine-based oil and a non-fluorine-based oil are being studied. For example, Patent Document 1 describes that a solid cosmetic containing a gelling agent in which a fluorinated oil is dispersed in a non-fluorinated oil is superior in terms of stability over time, feeling of use, makeup lasting, and prevention of color transfer. Patent Document 2 describes that a lipstick composition containing a fluorinated polymer in which a fluorinated oil is dispersed in a non-fluorinated oil has good emulsification stability and an excellent anti-color transfer effect. Document 3 describes that a liquid ester oil, a fluorine-based oil that does not dissolve therein, and a cosmetic that combines a fluorine-based oil that dissolves therein are excellent in the effect of preventing color transfer.
