ABSTRACT:
Compositions of fragrance oils are stabilized with respect to potency and aesthetic quality toward the effects of heat and age by including in the formulations a quantity of alkylphenol ethers of polyethylene glycol, or more specifically, alkyl phenoxy polyethoxy ethanols wherein the polyether chain averages from 5 to 13 moles of ethylene oxide, and the alkyl portion of the molecule ranges from 6 to 20 carbon atoms. The alkyl portion of the molecule may be branched, unbranched, saturated or unsaturated. The oils are stabilized in respect to durability or intensity of odor with time and are rendered relatively insensitive to the deleterious effects of heating and/or aging in the presence of air. The presence of the stabilizers also eliminates the phenomenon of the "migration" of the perfume oil caused by repeated vaporization and condensation within an enclosed space. In addition, the inclusion of the stated stabilizers, when judiciously used, tends to "round out" or "smooth out" the overall perception of the odor characteristics of the particular oils utilized, often increasing the aesthetic value of the fragrance composition when so used.
