Fragrant gel polymer with solvents

Abstract

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.

We claim: 
     
         1 . A process for preparing a fragrant gel comprising the steps of:
 blending a liquid mixture A including a fragrance oil and one of a polymer or a cross linking agent;   wherein said polymer is derived from one of maleinized butadiene, isoprene or chloroprene;   wherein said cross linking agent is derived from one of amine or polyetheramine;   blending a liquid mixture B including the polymer or the cross linking agent omitted from mixture A and a solvent, said mixture B being homogeneous and without any of said fragrance oil;   wherein said solvent is an ester, said solvent modifying the viscosity of mixture B, and functions as a plastifier to provide a fruit like smell to the fragrance oil of mixture A when combined, said ester including one of di-isoheptyl phthalate, 2-tert-butylcyclohexyl acetate, diethyl malonate, ethyl benzoate, benzyl butyrate, methyl benzoate, and benzyl benzoate;   adding a wetting agent to either mixture A or mixture B;   blending said mixture A with mixture B; and,   forming a gel carrying the fragrance following said blending of mixture A with mixture B with reduced syneresis and shortened setting time;   wherein said process reduces premature reaction of said polymer and said cross-linking agent; and   wherein said process produces a fragrance carrying gel that remains together as a whole.   
     
     
         2 . A process for preparing a fragrant gel comprising the steps of:
 blending a liquid mixture A including a fragrance oil and one of a polymer or a cross linking agent (at least 5% and at most 95% by weight);   wherein said polymer is derived from one of maleinized butadiene, isoprene or chloroprene (5%-50% weight by weight);   wherein said cross linking agent is derived from one of amine or polyetheramine;   blending a liquid mixture B including the polymer or the cross linking agent omitted from mixture A and a solvent (10%-90% W/W), said mixture B being homogeneous;   wherein said solvent is an ester, said solvent modifying the viscosity of mixture B, and functions as a plastifier to provide a fruit like smell to the fragrance oil of mixture A when combined, said ester including one of di-soheptyl pthathalate 2-tert-butylcyclohexyl acetae, diethyl molonate, ethyl benzoate, benzyl butyrate, methyl benzoate, and benzyl benzoate (range from 10%-90% W/W);   adding a wetting agent to either mixture A or mixture B, said wetting agent being included between about 1%-50% by weight of said mixture;   blending said mixture A with mixture B; and,   forming a gel carrying the fragrance following said blending of mixture A with mixture B with reduced syneresis and shortened setting time;   wherein said process reduces premature reaction of said polymer and said cross-linking agent; and   wherein said process produces a fragrance carrying gel that remains together as a whole.   
     
     
         3 . A process for preparing a fragrant gel comprising the steps of:
 blending a liquid mixture A (10% to 90%) including a fragrance oil and one of a polymer or a cross linking agent;   wherein said polymer is derived from one of maleinized butadiene, isoprene or chloroprene;   wherein said cross linking agent is derived from one of amine or polyetheramine;   blending a liquid mixture B (90% to 10%) including the polymer or the cross linking agent omitted from mixture A and a solvent, said mixture B being homogeneous and without any of said fragrance oil;   wherein said solvent is an ester, said solvent modifying the viscosity of mixture B, and functions as a plastifier to provide a fruit like smell to the fragrance oil of mixture A when combined, said ester including one of di-isoheptyl phthalate, 2-tert-butylcyclohexyl acetate, diethyl malonate, ethyl benzoate, benzyl butyrate, methyl benzoate, and benzyl benzoate;   adding a wetting agent to either mixture A or mixture B;   blending said mixture A with mixture B; and,   forming a gel carrying the fragrance following said blending of mixture A with mixture B with reduced syneresis and shortened setting time;   wherein said process reduces premature reaction of said polymer and said cross-linking agent; and   wherein said process produces a fragrance carrying gel that remains together as a whole.   
     
     
         4 . The process of  claim 3  and including an antioxidant to the said gel, said antioxidant being included at 0.5-2% by weight of the combined mixtures. 
     
     
         5 . The process for preparing a fragrant gel of  claim 4  wherein said antioxidants include at least one of 2,6-Di-tert-butyl-4(4,6-bis(octylthio)-1,3,5-triazin-2-ylamino)phenol and 2-hydroxy-4 n octyloxybenzophenone had improved or extended color stability longer than without. 
     
     
         6 . The process of  claim 2  and including adding fragrance oil into said mixture B. 
     
     
         7 . The process of  claim 2  wherein said wetting agent is an alcohol. 
     
     
         8 . The process of  claim 4  wherein said antioxidant may be one of 2,6-Di-tert-butyl-4(4,6-bis(octylthio)-1,3,5-triazin-2-ylamino)phenol and 2-hydroxy-4 n octyloxybenzophenone.
