An oil-in-water dispersion (I) has an oil phase comprising: (A) at least one water insoluble, room-temperature solid, oxygen containing organic substance comprising a long chain alcohol having at least one 12C atom hydrocarbon residue optionally containing S, SO or SO2, distillation residue arising from the production of aliphatic alcohols having at least 14C atoms, mono-, di or triglycerides of fatty acids, fatty acid esters of at least 12C aliphatic alcohols and/or fatty acid esters of 1-11C alcohols; (B) at least one amide compound of formula Z-X-B-N(R )-A-N(R )-C(=O)-R (1) and/or a product of the reaction of at least one amide compound of formula (1) having at least one reactive group (RG) comprising an alcoholic OH-group and amine NH- or NH2 groups, with at least one crosslinking compound having at least bifunctional reactivity with the groups (RG) and/or a reaction product of an amino group containing polymer with an aliphatic carboxylic acid R-COOH; and optionally (C) known defoaming agents; (D) at least one hydrocarbon having a b.pt. greater than 200 deg C (normal pressure).

    Abstract: A defoaming agent and/or deaerator for aqueous foamable media based on oil-in-water dispersions. The oil phase contains at least one compound from fatty alcohols, fatty acid monoglycerides, diglycerides, and triglycerides, fatty acid ester of fatty acids and monovalent to trivalent alcohols, 3-thiaalkane-1-ole, 3-thiaoxide alkane-1-ole, 3-thiadioxide-alkane-ole, and thiaalkane esters in combination with (i) at least one polyglycerine that is obtained by esterification of at least 20 percent of polyglycerine with 12 to 36 C carboxylic acid, and (ii) at least one bisamide consisting of ethylene diamine and 10 to 36 C atom carboxylic acids, while the aqueous phase thereof contains at least one stabilizer, water, and an optional thickener, for aqueous media that tend to foam. Also disclosed are methods of controlling foam by adding the dispersions to a process, particularly during cellulose boiling, cellulose washing, grinding of paper pulp, paper production, and dispersion of pigments used for paper production.
