摘要
A patch delivers a volatile substance to an environment. The patch provides the volatile substance within a solid layer positioned between a breathable layer and a barrier layer. A release liner is removably adhered to the barrier layer. The solid layer may be formed by mixing the volatile substance with a liquid agent that forms a solid below 40°C. The liquid mixture is applied to the breathable layer and allowed to solidify. The other layers are added thereto.
