Alkyl sulfate / alkyl ether sulfate gypsum foamer
A surfactant composition is disclosed comprising a first alkyl sulfate surfactant, optionally a second alkyl sulfate surfactant, and optionally an alkyl ether sulfate. The first and second alkyl sulfate surfactants have Formula (1):R1—OSO3−+M1 (1)and the alkyl ether sulfate has Formula (2):R2—(OCH2CH2)yOSO3−+M2 (2)in which R1 and R2 are independently selected linear or branched alkyl or a combination thereof having from 6 to 14 carbon atoms, y has an average value from 0.1 to 5, and M1 and M2 are cations independently selected from sodium, calcium, ammonium, or a combination of two or all of these. Use of the composition as a foaming agent for gypsum slurries, and of the gypsum slurries for formation of gypsum boards, are disclosed.
