A series of experiments were conducted to evaluate HEU = hydroxyethyl urea release and prolonged scent generation of typical components of a perfume mixture. Samples were prepared by mixing 10% 0.165 Vaporization of all fragrance components for the of scent boosting agent (Substituted urea and/or dihydrox combination of 5% GQ/5% HEU were better, and in some ypropyl quaternary ammonium salt) in water along with instances exceptionally better than the water base. With just a 0.05% Deep Moisture perfume oil. This oil is a mixture of few exceptions, the combination of GQ/HEU provided a bet components including but not limited to limonene, dihy terresult than GQ or HEU separately. From these results, it is dromyrcenol, gamma terpinene, benzyl acetate, linalool, evident that a combination of dihydroxypropyltrimonium pinene, isomethyl ionone and others. chloride and hydroxyethyl urea (GQ/HEU) operated to boost 0163 Samples were analyzed by gas chromatography scent into the headspace above the aqueous base formula.
