Abstract: A melt feed device for an injection molding apparatus having at least one nozzle element connected both to a first hot runner and a second hot runner for feeding both the first melt and the second melt into an injection molding mold. The nozzle has three substantially concentrically arranged feed passages, wherein the innermost and the outermost feed passage are in communication with the first hot runner and the central feed passage is in communication with the second hot runner. A closure element is provided that can be reciprocated between a first position in which the closure element closes all feed passages, a second position in which the closure element opens the outermost feed passage but closes the other two feed passages and a third position in which the closure element opens all feed passages. The invention also includes process and molds using the device.

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.
