<p>PURPOSE:Title coating film preparation that is composed of an aqueous emulsion of sorbitan diester with fatty acid and wax with an emulsifier and readily spreads on the surface of agricultural products to form coating films with adeaquate moisture and air permeability, thus keeping the freshness and promoting the rootage and growth. CONSTITUTION:Title coating film preparation is prepared by mixing 3-15wt%, based on the total weight of the preparation, of sorbitan diester with 12-22C fatty acid, 1-7wt% of wax of 25-60 carbon atoms, 1-7wt% of emulsifier selected from soaps of fatty acids of 12-18 carbon atoms, when necessary morpholine salt with fatty acid of 12-22 carbon atom to form an aqueous emulsion with an average particle size of 1-100mu.</p> |
