Attorney, Agent or FirmInternational ClassA61K 007/06AbstractBy incorporating an alkyl polyol and a water soluble or emulsifiable silicone based compound into a moderately viscous gel-type hair conditioning composition, a hair conditioning gel formulation is attained which is able to be delivered in a spray mist pattern using conventional small diametered pump spray nozzles. Preferably, the alkyl polyol has a carbon content ranging between 2 and 8, and the hydroxyl ion content ranges between 2 and 7 and are not spaced apart by more than 4 carbon atoms. It has been found that by employing this invention, the resulting gel formulation is able to be dispensed consistently, repeatedly and easily in a liquified spray mist through a pump nozzle having apertures ranging between about 0.010 and 0.030 mm. | |
