Problems solved by technology

However, since the modified guar gum is derived from natural products, it is difficult to obtain a modified guar gum with a certain degree of modification of the substituent, and it is difficult to reduce the concentration of alcohol or viscosity after using the modified guar gum. The physical properties of the gel-like composition remain constant
In addition, since the acquisition of guar gum derived from natural products tends to be unstable, there is a problem that the acquisition of modified guar gum itself tends to be unstable.

Abstract

The present invention addresses the problem of providing a technique for obtaining a highly practical gel composition which employs an alcohol as a solvent to be gelled, and does not require a means for heating or the like. The gel composition is characterized by containing hydroxyalkyl cellulose, hydroxyalkyl alkyl cellulose, an alcohol, and water.

Description

technical field [0001] The present invention relates to an alcohol-based gel composition. More specifically, the present invention relates to an alcohol-based gel composition that can be produced without heating using alcohol as a main solvent and a method for producing the composition. Background technique [0002] Conventionally, in various fields, a gel composition obtained by gelling using water or alcohol as a solvent and using a gelling agent has been widely used. For gels with alcohol as the main solvent, compared with gels with water as the main solvent, the freezing point is lower, and the antifreeze effect can be obtained in low temperature environments, so it can be used even in refrigerators and cold regions. gel composition. In addition, it is useful even when alcohol itself is used as an active ingredient or in an environment where water is avoided. However, practical techniques for gelling alcohols are less reported compared to water. [0003] For example, ...
