The fragrant gel polymer system is a process where a complete fragrance formulation remains whole and is then blended with either a polymer or a cross-linking agent. The non-fragrance carrying polymer is then liquefied and made homogenous with a solvent, including esters. The solvents modify viscosity and ease the mixing of the non-fragrance carrying polymer with the fragrance carrying polymer. The method also provides surfactants and wetting agents for further integration and mixing of the fragrance oils with either the polymer or the cross-linking agent during the steps of the process. Mixing of the fragrance carrying polymer and the non-fragrance polymer results in a gel that sets in less time and with less syneresis than existing processes.

useful as a perfume ingredient.

An olfactory sensory book that is operable to provide an olfactory stimulation that correlates to portions of the content of the book. The invention includes at least one perimeter panel wherein the perimeter panel has formed therein a plurality of scent compartments. The scent compartments have an opening wherein the opening is sealably secured with a removable cap member. The scent compartments include an interior volume wherein disposed within the interior volume is an absorbent material. The absorbent material is operable to be saturated with a volatile compound. Removal of the cap member during use of the book of the invention provides release of the fragrance of the volatile compound saturated on the absorbent material. The scent compartment is further configured with a slot and a screen member wherein the slot facilitates release of the fragrance. A rear access panel provides access to the interior volume of the scent compartment.
