Description

  The present invention relates to an oily cosmetic.

Conventionally, oily cosmetics having excellent color durability using a solid wax, nonionic silicone, or the like have been studied.
For example, Patent Document 1 discloses a lip cosmetic containing a specific surface-treated organic pigment, silicone having a nonionic hydrophilic group, liquid ester oil / higher alcohol, and suppresses a change in color upon heating.
