  • Patent number: 9925194
    Abstract: The solubility of kinetin and/or of zeatin is increased when either or both are combined in a formulation that includes a polyoxyalkylene-n-glycerol dicarboxylate component and a fatty acid component. These two components provide a synergistic increase in the solubility of kinetin and/or zeatin that is greater than that which would be expected based on the solubility of kinetin and zeatin in the individual components.
