関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a liquid crystal type external base material, and more specifically, a liquid crystal structure composed of a specific component containing a higher alcohol is used to provide a transparent feeling and hardness. The present invention relates to a liquid crystal type external base material which has a low temperature dependency, excellent stability over time, and is free from stickiness during application and provides a refreshing feeling of use.

知られている。[Prior Art] Higher alcohols are widely used as a base for external use. For example, in an emulsified ointment such as a water-absorbent ointment or a hydrophilic ointment, the effect of enhancing the viscosity of the system and enhancing the stability of the ointment can be expected by adding a higher alcohol to give a refreshing feeling. It is also well known that this effect is due to the higher alcohol taking a liquid crystal structure in the ointment.

した使用感が得られない。[Problems to be Solved by the Invention] However, higher alcohols are used only as an emulsion stabilizing aid, and the liquid crystal structure of higher alcohols is very unstable. This resulted in problems such as poor temperature resistance, especially around 40 ° C, which is the high temperature side, and precipitation of crystals with a pearly luster due to the destruction of the liquid crystal structure and a decrease in viscosity.
As a method to solve these drawbacks, the amount of higher alcohol is reduced and paraffin, petrolatum, and other solid hydrocarbons are blended at room temperature, and water-soluble polymers such as gum arabic, carboxyvinyl polymer, and hydroxypropyl cellulose are used. However, when these additives are used, the liquid crystal structure becomes cloudy and the transparency characteristic of the liquid crystal is lost. Furthermore, when a large amount of these additives is used in order to improve the stability of the system, the stickiness increases and a refreshing feeling is not obtained.
