FOAMING AGENT

摘要

A foaming agent comprising a blend of alkyl sulfates and alkyl ether sulfates having an improved foaming performance. The blend has the general formula: Rx- (OCH2CH2)y-OSO3M wherein at least 90% of x is between 8 and 10. The Rx forms an alkyl chain that is either linear and/or branched and the average y is between 0.4 and 1.3. M is a cation producing a water soluble surfactant. A method of using these foaming agents in the making of gypsum products and in the resulting gypsum products is also disclosed. The foaming agents may also be used for other purposes, for instance, as fire fighting foams.
