GEL COMPOSITION AND PRODUCTION METHOD THEREFOR, AND SHRINKAGE IMPROVING AGENT AND SHRINKAGE IMPROVING METHOD FOR GEL COMPOSITION

摘要

The present invention addresses the problem of providing a technique for obtaining a gel composition which shrinks so as to maintain geometric similarity when volatilization of a solvent or an active ingredient occurs, and of which the end point of the effect can be easily visually recognized. The gel composition according to the present invention having solved the problem is characterized by containing the following components (A)-(D): (A) a gelling agent; (B) glycerin; (C) an alcohol; and (D) water, wherein the gelling agent as component (A) contains the following component (a1) or (a2): (a1) hydroxypropylated guar gum; or (a2) hydroxyalkyl cellulose and hydroxyalkyl alkyl cellulose.
