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.

A cologne comprising particles of a composition consisting essentially of (a) from about 1 up to 10 parts by weight of a non-confined fragrance oil substance selected from the group consisting of non-confined hydrophobic fragrance oils and aqueous emulsions of fragrance oils; (b) from about 2 up to about 10 parts by weight of an entrapped fragrance oil capable of being released hydrolytically or by means of application of mechanical pressure, said fragrance oil being physically entrapped in a particulate material selected from the group consisting of gelatin, dextrin, gum acacia, urea formaldehyde polymers, modified food starch and synthetic polymers capable of being dissolved or decomposed hydrolytically, said solid material having a particle size of from about 3 microns up to about 400 microns, said physically entrapped fragrance oil being organoleptically compatible with said non-confined hydrophobic fragrance oil or fragrance oil emulsion; and (c) from about 0.1 up to about 10 parts by weight of a suspending agent selected from the group consising of hydroxypropyl cellulose having a molecular weight of from about 50,000 up to about 800,000; xanthan gum, ethyl cellulose, silica, suspensions of finely divided clay in water, suspensions of an aqueous fluid-absorbing composition comprising water in soluble alkali salts of aqueous alkali saponified, gelatinized-starch-polyacrylonitrile graft polymers which contain gelatinized starch (GS) and saponified polyacrylonitrile (HPAN) in molar ratios of from about 1:1.5 to about 1:9 GS:HPAN, whereby after the cologne is intimately admixed with ethanol and water a fragrance is released at high fragrance intensity substantially evenly and uniformly over an extended period of time.
