Abstract: The present invention relates to a method of producing mineral oil from underground mineral oil deposits, in which an aqueous formulation comprising at least a mixture of alkyl ether carboxylate and corresponding alkyl ether alcohol, where the alkyl ether carboxylate has been prepared from the alkyl ether alcohol and the molar ratio in the mixture of alkyl ether carboxylate:alkyl ether alcohol is from 51:49 to 92:8, is injected through at least one injection well into a mineral oil deposit, where the deposit has a deposit temperature of 55°C to 150°C, a crude oil having more than 20° API and a deposit water having more than 100 ppm of divalent cations, and crude oil is withdrawn through at least one production well from the deposit. The invention further relates to the preparation of the mixture and to a concentrate comprising the mixture.

Abstract: The present invention relates to low-foam surfactant mixtures comprising esters of the general formula (I) (see formula I) and alcohols thereof of the general formula (Ia) (see formula Ia) where R is a branched or unbranched alkyl radical having from 8 to 22 carbon atoms; R a, R1 are each independently hydrogen or a branched or unbranched alkyl radical having from 1 to 5 carbon atoms; R2 is a branched or unbranched alkyl radical having from 5 to 17 carbon atoms; I, n are each independently from 1 to 5 and m is from 38 to 70,and where the ratio of the molar amounts of the esters (I) to the alcohols (Ia) is at least 17:3. The invention further relates to the process for preparing them and to their use and to washing and cleaning composition formulations comprising them.
