    Abstract: Methods of recovering cannabinoids from cell cultures include methods comprising steps of separating the cell culture at a temperature above the melting point of the cannabinoid to separate a light phase comprising liquid state cannabinoid from a heavy phase; and methods comprising treating the cell culture at a temperature below the melting point of the cannabinoid to separate a light phase from a heavy phase comprising solid state cannabinoid. Other methods include contacting the culture with a water-miscible solvent to form a water-miscible phase and an aqueous phase, separating the two phases and recovering the cannabinoid. Other methods include contacting the culture with a water-immiscible solvent to form a water-immiscible phase and an aqueous phase, separating the two phases, and recovering the cannabinoid. Other methods include washing the inner surface of a fermentation vessel with alkaline solution to recover cannabinoid attached to the vessel surface. Various methods make use of aqueous solvent systems comprising no organic solvent, aqueous solvent systems comprising added water-miscible organic solvent, and dual-phase aqueous/water-immiscible solvent systems.

    Abstract: The disclosure provides embodiments directed to a composition comprising a 1,3-butylene glycol (1,3-BG; such as but not limited to, bioBG) and one or more fragrance ingredients, which form a fragrance component of the composition. 1,3-BG demonstrates exemplary qualities and characteristics of being natural, sustainable, and substantially non-odorous, for use in fragrance compositions. Methods of using or applying such 1,3-BG fragrance compositions provide a cost-efficient, sustainable composition, since 1,3-BG does not mask or alter the fragrance notes of the fragrance ingredients allowing for the use of smaller quantities of fragrance ingredients. The 1,3-BG fragrance compositions of the disclosure also improve fragrance performance and reduces greenhouse gases, while avoiding any irritation, sensitization, or allergic reaction in humans.
