Process for producing liquid loaded powders. |
摘要 |
<p>The specification describes a process for producing liquid-loaded powders which are capable of releasing their liquid load when subjected to shearing forces. A cellulosic polymer and a liquid load are dissolved in a polar solvent to form a solution. The solvent is then dispersively evaporated from the solution to form a liquid loaded powder. Dispersive evaporation of the solvent in a spray drying tower is described. Cellulosic polymers exemplified in the specification include cellulose triacetate, an ethyl cellulose and a cellulose propionate. Solvents exemplified include methylene chloride, ethyl acetate and acetone. Uses of the liquid loaded powder described include a carrier for fragrances used in toilet soap formulation, a sunscreen formulation in powder form, an insect repellent in powder form, a baby oil and a moisturizer in powder form.</p> |
