Abstract
Described are hydro-alcohol compositions of matter including, but not limited to, colognes, after-shave lotions, after-bath preparations and splash lotions, which yield continuously high fragrance intensity release, evenly and uniformly over an extended period of time and which can be adapted to yield differing aromas from a qualitative and quantitative standpoint in a controllable manner containing a mixture of (i) a non-confined fragrance composition; (ii) one or more fragrance oils which are physically entrapped in one or more types of solid particles and (iii) a suspending agent such as hydroxypropyl cellulose, silica, xanthan gum, ethyl cellulose or combinations of the previously mentioned four substances; the non-confined fragrance substance, the entrapped fragrance oil and the suspension agent being premixed prior to the subsequent creation of the hydro-alcohol compositions of matter.
