Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid bar cosmetic containing candelilla resin,
The present invention relates to a pencil-shaped or fed-out solid bar-shaped cosmetic material having excellent adhesion to skin and lips, dispersibility of pigments, ease of use, and water resistance of a cosmetic film, and reduced odor peculiar to a resin.

[0002]

2. Description of the Related Art Conventionally, in the case of a solid or bar-shaped cosmetic such as a pencil or a dispenser, waxes for maintaining the shape, liquid oils and paste oils for sensory adjustment, organic and inorganic pigments for producing a color tone, and radiance. It has been composed of a pearl agent, a lame agent, and the like, which produce properties. Recently, in addition to these,
For the purpose of improving adhesion to skin and lips, dispersibility of pigments, and water resistance of a cosmetic film, a resin component such as a rosin acid ester has been frequently added.

[0003]

However, when these resin components are blended in a large amount for the purpose of further improving adhesion and water resistance, the flexibility at room temperature is poor, so that the usability may be deteriorated. there were. Furthermore, these resin components often have a peculiar odor and tend to increase over time, which is disadvantageous in terms of fabric odor.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, a solid bar-like cosmetic containing candelilla resin has been found to have an adhesive property to the skin and lips and a pigment dispersing property. The present invention was also found to be excellent in stability over time, to improve the water resistance of the decorative film, to have no odor peculiar to the resin, and to be excellent in usability, and to complete the present invention. That is, the present invention provides a solid bar cosmetic containing a candelilla resin.
