A surfactant of structure (I) is useful as a biodegradable low foaming surfactant: where m is a value in a range of 3 to 10, n is a value in a range of 5 to 20 and z is a value in a range of 10 to 25. 

Branched biodegradable low foam nonionic surfactants

Disclosed are compositions of the formula wherein Rand Rare each independently hydrogen or a linear or branched alkyl group containing from (1) to about (18) carbon atoms, provided that Rand Rtogether contain from about (8) to about (18) carbon atoms, and further provided that less than about 10 mole percent of Ror Ris hydrogen; Ris hydrogen or an alkyl radical containing from (1) to about (6) carbon atoms; Rand Rare each independently hydrogen or an alkyl radical containing from (2) to about (6) carbon atoms, provided that Rand Rtogether contain from (2) to about (6) carbon atoms; m is an average value ranging from (0) to about (10), and n is an average value ranging from about (3) to (about 40), provided that the group containing m and the group containing n may be exchanged with one another as to position; and z is an average value ranging from about (0.5) to about (5). These compositions are conveniently prepared by a process including at least two steps and are useful as surfactants.

Alkylene oxide-capped secondary alcohol alkoxylates useful as surfactants

Novel mixtures of long-chain (C10-C20) olefins are functionalized by conversion to aldehydes using an OXO process, or to sulfates, sulfonates, sulfones, sulfides, or sulfoxides by direct sulfonation. The aldehydes may then be hydrogenated to form alcohols, or aminated to form amines or amides. The olefins starting mixture may be acquired as a byproduct of the tetramerization of ethylene in the presence of certain chromium-containing tetramerization catalysts. The functionalized mixtures, and derivatives prepared therefrom such as alkoxylates prepared from the alcohols, may be useful as surfactants that may offer improved performance in many applications, while their preparation based on a byproduct mixture reduces their cost and also reduces waste-handling issues for this non-targeted stream.

Functionalized long-chain olefin mixtures and uses therefor

Surfactant compositions that include one or more nonionic surfactants derived from seed oils and having a mixture of at least 8, 10 and 12 carbon atom linear alkyl moieties find use in a number of end use applications as substitutes for petroleum derived surfactants.
