The invention relates to a compound of following formula (I): ##STR00001##
a preparation process, uses thereof and compositions containing the same, wherein R.sub.1 and R.sub.2, represent, independently of one another, a linear, branched or cyclic, saturated or unsaturated hydrocarbon-based group comprising from 1 to 6 carbon atoms, where the sum of the carbon atoms of the groups R.sub.1 and R.sub.2 ranges from 2 to 7, and where R.sub.1 and R.sub.2 may also form, together and with the carbon atom bearing them, a 6-, 7-, or 8-membered ring; n is an integer of between 1 and 100, limits included; A represents a sequence of one or more units chosen from ethylene oxide, propylene oxide, butylene oxide units and mixtures thereof; the group formed by R.sub.1, R.sub.2 and the carbon atom to which R.sub.1 and R.sub.2 are attached has a degree of branching equal to 0, 1 or 2.

A wetting agent according to Formula (I): ##STR00001## wherein R.sup.1 is selected from a branched alkyl group or linear alkyl group or a cycloaliphatic group or an aromatic group, each having 6 to 15 carbon atoms; R.sup.2 is selected from hydrogen, methyl, or ethyl; R.sup.3 is selected from hydrogen, methyl, or ethyl; R.sup.4 is selected from hydrogen, methyl, or ethyl; R.sup.5 is selected from methyl or ethyl; x ranges from 0 to 5; y ranges from 0 to 10; z ranges from 1 to 10; with the proviso that when x ranges from 1 to 5, R.sup.2 is different from R.sup.3; and with the proviso that when x=0, R.sup.3 is different from R.sup.4. The wetting agent also imparts anti-foam properties to aqueous solutions while reducing surface tension.

A method of producing a reduced glycol fatty alcohol ethoxylate material may include removing at least a portion of glycol in the fatty alcohol ethoxylate material. A method of producing a reduced glycol sulfate ethoxylated sulfate surfactant may include, removing at least a portion of glycol in an ethoxylated fatty alcohol raw material before the ethoxylated fatty alcohol raw material is sulfated to produce the reduced glycol sulfate ethoxylated sulfate surfactant. A surfactant including an ethoxylated fatty alcohol with 100 ppm or less by weight of free glycol. A surfactant including a sulfated ethoxylated alcohol with 100 ppm or less by weight of diethylene glycol monosulfate sodium.

A higher secondary alcohol alkoxylate precursor is obtained by reacting a long-chain olefin with a (poly)alkylene glycol. The precursor has a content of (poly)alkylene glycol of 0.2% by mass or lower with respect to the total mass of the higher secondary alcohol alkoxylate; a higher secondary alcohol alkoxylate adduct which is an alkylene oxide adduct of the higher secondary alcohol alkoxylate precursor; and a higher secondary alkyl ether sulfate ester salt which is a sulfated product of the higher secondary alcohol alkoxylate precursor or the higher secondary alcohol alkoxylate adduct.

Method for lowering aldehyde content in a mixture comprising (i) diethylene glycol (DEG) and/or triethylene glycol (TEG) and (ii) aldehyde are disclosed. An ion exchange resin is soaked in monoethylene glycol. The mixture comprising 5 to 200 ppm aldehyde is then flowed to make contact with the soaked ion exchange resin to produce a product comprising DEG and/or TEG and less than 15 ppm aldehyde.
