Claims
- 1. A method for making intermediate quality snow comprising the steps of:a) incorporating an amount of organopolysiloxane surfactant into water to produce a snow property enhancingly effective composition; and b) spraying said composition in the form of droplets into a fan-generated large volume, unidirectional mechanical movement of air at substantially atmospheric pressure and at a temperature below about 0° C., thereby to effect at least partial crystallization of the droplets of the composition in said spray to form the intermediate quality snow.
- 2. The method of claim 1 wherein the organopolysiloxane is corporated into the water at a concentration of from about to about 50 ppm.
- 3. A method for making intermediate quality snow comprising the steps of:a) incorporating into water an amount of organopolysiloxane surfactant to produce a snow property enhancingly effective composition, the organopolysiloxane surfactant being of the formula: MDyD′xM wherein M=Me3SiO0.5 D=Me2SiO D′=Me R SiO Me=CH3 R=CnH2nO(C2H4O)a(C3H6O)bR′ wherein n is from 2 to 4; a is from 3 to 25; b is from 0 to 25; wherein the oxyalkylene groups are random, block or mixtures of oxyalkylene units; R′=hydrogen, an alkyl group having 1 to 4 carbon atoms, or an alkyl ester group wherein the alkyl group of the ester has 1 to 4 carbon atoms y=0 to 5; and x=1 to 5; and b) spraying said composition into a fan-generated large volume, unidirectional mechanical movement of air at substantially atmospheric pressure and at a temperature below about 0° C., thereby to form droplets and to effect at least partial crystallization of the droplets of the composition in said spray to form intermediate quality snow.
- 4. The method of claim 3 wherein the organopolysiloxane is corporated into the water at a concentration of from about to about 50 ppm.
