An ibuprofen-sustained release tablet or tablet layer is formed by making a wet granulation using povidone (PVP) in alcohol as the granulating fluid which is mixed with ibuprofen ethylcellulose, a wicking agent e.g. microcrystalline cellulose, an erosion promoter e.g. pregelatinized starch, then drying and milling the granulation and blending with dry powdered erosion promotor, wicking agent, lubr...

The invention relates to surface-active agents which are produced from byproducts of papermaking. Lignin, modified lignin, resin acid and tall oil fatty acid are reacted with a polyamine in order to obtain an amino condensate, and this amino condensate is reacted with a bisulphite and formaldehyde in aqueous solution in order to obtain the new, surface-active agents.

A gas producer is disclosed for filling a gas cushion restraining device for occupants of vehicles. The gas producer includes a combustion chamber filled with fuel and surrounded by a wall which exhibits apertures for the discharge of the gas produced, said apertures being sealed hermetically by a destructible cover at the start of the burning process of the fuel up to a specific pressure rise in ...
