Abstract
A diffusing device containing a fragrance or deodorant material includes a gel of a water swellable/water absorbing resin carrying the fragrance and/or deodorant components. The fragrance or deodorant release device can be readily produced on an industrial scale, is easy for a user to handle, and employs a water swellable/water absorbing resin. The gel is produced by enclosing a water swellable/water absorbing resin in a water resistant container, such as a packet, having a water permeable portion and immersing the packet into an aqueous medium containing the fragrance and/or deodorant components whereby the resin absorbs the fragrance and/or deodorant components.
