Abstract

1,198,310. Collagen. ETHICON Inc. 22 Dec., 1967, No. 58360/67. Heading C3H. A process for preparing a dispersion of swollen collagen in an aqueous acid medium comprises treating finely divided collagen for a period of 4 to 18 hours with a solution of a borohydride at a temperature within the range of 7‹ to 36‹ C. and then swelling the collagen in the aqueous acid medium. Sodium, potassium and tetramethylammonium borohydrides are mentioned. The acid may be acetic or cyanoacetic acid.
