Title: Improvements in the manufacture of dispersing agents
IPC: C11C3/02
Filed: 1946-03-13
Abstract: Products useful as dispersing and stabilising agents in water-in-oil emulsions are obtained by re-esterifying a polymerised and possibly oxidised drying or semi-drying fatty acid triglyceride with 10 to 20 per cent of glycerol, calculated on the weight of triglyceride.  In a modification, the triglyceride may be replaced by a corresponding mixture of polymerised and possibly oxidised fatty acid and glycerol, and in either case the product may be further polymerised and, if desired, oxidised.  In further modifications, the polymerised and possibly oxidised triglyceride may be replaced by the untreated triglyceride or a corresponding mixture of fatty acid and glycerol, in either of which events the product is polymerised and, if desired, oxidised.  An example is given of the re-esterification of polymerised soya bean oil, and reference is made also to the treatment of linseed oil, sunflower-seed oil, cotton-seed oil, wood oil, whale oil and fish oil.  Specifications 455,540 and 474,717 are referred to.ALSO:Products useful as dispersing and stabilising agents in water-in-oil emulsions are obtained by re-esterifying a polymerised and possibly oxidised drying or semi-drying fatty acid triglyceride with 10-20 per cent of glycerol, calculated on the weight of triglyceride.
