Title: A dusting powder including carboxymethyl dextran salts
Inventor: NOVAK LEO J
IPC: C08B37/02
Filed: 1959-01-20
Abstract: The invention comprises a free-flowing, mobile dusting powder comprising one or more of (a) alkali metal salts of carboxymethyl dextran, (b) alkaline earth metal salts of carboxymethyl dextran, and (c) the ammonium salt of carboxymethyl dextran, and mixtures thereof, the particles having an average size of 40 to 300 microns.  The metal salts may be the sodium, potassium, lithium, magnesium, calcium and strontium salts, or mixtures of the salts may be used.  Preferred salts are derived from native, unhydrolysed high molecular weight, water-soluble or water-insoluble dextran and contain an average of 2,0 to 3,0 carboxymethyl groups per anhydroglycose unit.  Blends may comprise from 5 to 95% of a watersoluble salt with 95 to 5% of a water-insoluble relatively non-hygroscopic salt.  The carboxymethyl dextran salts may be mixed with the free carboxymethyl dextran ether or with other dusting powders such as talc, mica, di-calcium phosphate, magnesium carbonate, and various forms of starch.  The alkali metal salts may be obtained as initial products in the preparation of carboxymethyl dextrans. For example when dextran is reacted with an excess of sodium or potassium perchloracetate in aqueous solution or dispersion containing excess sodium or potassium hydroxide at 50 DEG  to 100 DEG C. for 10 minutes to 2 hours, the reaction product is an alkali metal salt of a carboxymethyl dextran which can be precipitated by a water-miscible alcohol or ketone.  The salt is then ground or pulverized to a particle size of 40 to 300 microns.  Alkaline earth metal or ammonium salts may be obtained by recovering the free ether from the alkali metal salt and then reacting it, in aqueous medium with the appropriate base.ALSO:A free-flowing mobile dusting powder comprises one or more of (a) alkali metal salts of carboxymethyl dextran, (b) alkaline earth metal salts of carboxymethyl dextran and (c) the ammonium salt of carboxymethyl dextran, and mixtures thereof, the particles having an average size of 40 to 300 microns.  The metal salts may be the sodium, potassium, lithium, magnesium, calcium and strontium salts. The sodium and magnesium salts are water-soluble, highly hydrophilic or hygroscopic, whereas the calcium and strontium salts are water-insoluble, non-hydrophilic or non-hydroscopic.  By varying the relative proportions of the salts, dusting powders having varying moisture pick-up and retention capacities are provided.  These characteristics can also be varied by selection of the starting dextran and the degree of substitution thereof by carboxymethyl groups.  The carboxymethyl dextran salts may be mixed with the free carboxymethyl dextran ether or with other dusting powders such as talc, mica, dicalcium phosphate, magnesium carbonate and various forms of starch.
