摘要

The present invention relates to a slow-release gel composition for a volatile substance, comprising a volatile substance, a poly-N-vinylcarboxylic acid amide-base cross-linked resin, a surfactant, water and, if desired, an alcohol. The invention has the following advantages: (1) the gel composition can be manufactured at room temperature; (2) a solution containing a surfactant for dispersing and solubilizing the volatile substance and an alcohol can be gelled by liquid absorption; (3) and the gel composition has excellent light stability.
