ABSTRACT:
Methods of forming clear fragrances and formulations are described herein. The method includes providing a commercial fragrance formulation including a first concentration of a fragrance component and a second concentration of a nonessential component. The method further includes identifying the nonessential component, wherein the nonessential component includes an alcohol, an ester, a hydrocarbon, an aldehyde, a resin, other crystalline aroma chemicals, a first essential oil or combinations thereof, determining the second concentration and removing at least a portion of the nonessential component from the commercial fragrance formulation to form a first formulation, wherein the portion of the nonessential component is from about 5 wt. % to about 95 wt. % of the commercial fragrance formulation. The method further includes adding an essential component to the first formulation to form a second formulation, wherein the essential component is added to the first formulation in an amount substantially equal to the portion of the nonessential component removed from the commercial fragrance formulation. The method can further include preparing a second composition from the second formulation and processing the second composition to form the clear fragrance, wherein the processing comprises mixing, heating to a temperature of from about 20° C. to about 68° C. or combinations thereof, and wherein the clear fragrance is adapted to enhance solubility, enhance functional compatibility, enhance performance, reduce sweating or combination thereof, of the clear fragrance when added to an article.
