The present invention relates to novel compounds of the formula ##STR1## wherein R.sub.1 is an alkyl group, M.sup.+ is a cation, R.sub.2 is an alkylene oxide and n is an integer from 1 to 4. Surfactant compositions containing these novel compounds, the process of preparing these novel compounds as well as the methods of using these surfactant compounds in enhanced oil recovery, as emulsifiers, in emulsion polymerization, as hydrotropes, in foamed drilling fluids, as dye carriers, as textile detergents, as foaming agents for concrete formation and as fiber lubricants are also disclosed.

Alkoxylated alkyl substituted phenol sulfonates compounds and

An anionic silicone defoamer having the following general formula: ##STR1## wherein: R is alkyl;

Anionic silicone defoamer

A defoamer composition comprising a precipitated hydrophylic silica suspended in a water-immiscible inert liquid carrier, and reacted in situ with specific molar proportions of a trichloro-organosilane and a dichloro-organosilane, preferably in this respective order, to yield a stable hydrophobic silica suspension in an inert carrier, useful as a defoaming agent for aqueous systems, being effective at concentrations as low as 0.0005 percent. When one of said chloro-organosilanes contains an unsaturated bond, the composition may be further halogenated or sulfated.
