    • Disclosed is a surfactant composition and its use in the production of a gypsum product. Also disclosed is a method of producing gypsum plasterboard, as well as gypsum plasterboard that is formed from foamed slurry comprising the surfactant composition. The surfactant composition comprises from 60 to 99 wt.% by total surfactant weight of an alkyl sulphate component having the structure: R 1 -OSO 3 " + M 1 , in which R 1 is an alkyl having from 9 to 11 carbon atoms and M 1 is a cation. The surfactant composition also comprises from 1 to 40 wt.% by total surfactant weight of an alkyl ether sulphate component having the structure: R 2 -(OCH 2 CH 2 ) y OSO 3 - + M 2 , in which R 2 is an alkyl having from 8 to 10 carbon atoms, y has an average value of 0.1 to 5 and M 2 is a cation.
