Abstract

The present invention relates to defoaming compositions comprising compounds having the formula C 5 H 11 CH(CH 2 CH 2 CH 3 )CH 2 O(CH 2 CH(X)O) n H (I) where X═(CH 2 ) a CH 3 where a=0 or 1 and where n=0.5-5; and one or more hydrotropes selected from the group consisting of branched or linear C4-C10 alkyl glycosides and optionally one or more anionic hydrotrope selected from the group consisting of fatty acid soaps where the acyl group contains 10-22 carbon atoms, and which could be saturated or unsaturated, linear or branched; or a sulfonate chosen from the group cumene sulfonate and xylene sulfonate, and the use of such compositions as defoaming and/or antifoaming agents. The invention also pertains to a composition comprising a) a compound C 5 H 11 CH(CH 2 CH 2 CH 3 )CH 2 O(CH 2 CH(X)O) n H (I) where X═(CH 2 )aCH 3 where a=0 or 1 and n=0.5-5 b) one or more hydrotrope selected from the group consisting of branched or linear C4-C10 alkyl glycosides, c) optionally one or more anionic hydrotrope selected from the group consisting of fatty acid soaps where the acyl group contains 8-22, preferably 9-18 carbon atoms, and which could be saturated or unsaturated, linear or branched; or a sulfonate chosen from the group cumene sulfonate and xylene sulfonate, and d) N,N-bis(3-aminopropyl)dodecylamine.

Claims (6)

1. A composition comprising a compound of formula (I):

C 5 H 11 CH(CH 2 CH 2 CH 3 )CH 2 O(CH 2 CH(X)O) n H  (I)

where X═(CH 2 ) a CH 3 where a=0 or 1 and where n=0.5-5; one or more hydrotropes selected from the group consisting of branched or linear C4-C10 alkyl glycosides; and N,N-bis(3-aminopropyl)dodecylamine.

2. A composition according to claim 1 where the hydrotrope is n-hexyl glucoside or 2-ethylhexyl glucoside.

3. A composition according to claim 1 which contains less than 0.01 wt % of, N,N-bis(3-aminopropyl)dodecylamine.

4. The composition of claim 1 , wherein said composition is an alkaline Cleaning In Place (CIP) formulation, hard surface cleaning formulation, a biocide formulation, a laundry formulation, a household cleaning formulation, a metal working formulation, or in a paint or coating formulation.
