the fragrant gel polymer system is a process where a fragrance formulation is divided and blended with a polymer and a cross - linking agent . the polymer is then liquefied and made homogenous with a solvent , including esters . the solvent modifies viscosity and later eases the mixing of the polymer with the cross - linking agent . the cross linking agent is then liquefied and blended with water and aliphatic alcohol reducing steric hindrance . mixing of the fragrance carrying polymer and the cross linking agent results in a gel that sets in less time and with less syneresis than existing processes . the resulting gel achieves a near transparent form and receives dyes while attaining various molded shapes .
