Abstract: A process of preparing an essentially pyrogen-free gelatin solution from cattle hides and/or tanner's stock is described. The essentially pyrogen-free gelatin solution and the use of the pyrogen-free gelatin solution for various pharmaceutical, surgical and medical uses are also described.

Abstract: The invention provides a sprayable plant care composition which, in its preferred aspects, comprises a continuous aqueous phase comprising gelatin hydrolysate, urea, dissolved phosphorus and potassium salts, and an amount of preservative effective to prevent microbial growth in the composition; a dispersed phase comprising orange peel wax and glycerol as a diluent for the wax; and an emulsifier comprising polyoxyethylene (20) sorbitan monostearate in an amount effective to provide a stable emulsion and provide a cleansing action when the composition is applied to the foliage of a plant. When applied as a spray to plant leaf surfaces, the composition produces an attractive shine and an appealing aroma, provides plant nutrients absorbable by the leaf, and serves as an effective rinse to cleanse the leaf.
