Description

  The present invention comprises palmitic acid / 2-ethylhexanoic acid dextrin having an acyl substitution degree of less than 2.0, tetraester oil of pentaerythritol and a branched fatty acid having 14 to 22 carbon atoms, and silicic anhydride having an average particle size of less than 50 nm. More specifically, it is related to a liquid oily lip cosmetic, and more specifically, it has a light, glossy, glossy, excellent adhesion and durability, and does not discharge oil on the surface of the cosmetic. It is about.

Conventionally, in oily lip cosmetics, oily cosmetics have been used as a dosage form having a high makeup sustaining effect. Hydrocarbons, esters, higher alcohols, silicone oils and the like are used as liquid oils for liquid oily lip cosmetics. Moreover, in order to improve the dispersion stability of the powder color material in the liquid oily lip cosmetic, a method of blending solid oil or semi-solid oil or a gelling agent has been employed. In addition, since the lip is a part with particularly large movement, it is common to add a large amount of highly polymerized hydrocarbon oil such as heavy fluid isoparaffin or polybutene in order to maintain the adhesive effect and improve the gloss.

In recent years, liquid oily lip cosmetics are required not only for film uniformity and good adhesion properties, but also for a feeling of use such as good spread and no stickiness, and cosmetic effects such as gloss. Non-solid, transparent, non-sticky, glossy, and long-lasting by containing highly polymerized hydrocarbon oils such as dextrin fatty acid ester and heavy liquid isoparaffin, and liquid oil components at room temperature Non-aqueous oily cosmetic techniques are disclosed. (For example, refer to Patent Document 1). Also disclosed is a technique containing a dextrin fatty acid ester having an acyl substitution degree of 2.0 or less and an oil having a specific solubility parameter. (For example, see Patent Document 2)
