Claims29
A composition, comprising
- the product of contacting
- a) a partial or full dispersion, emulsion, suspension, or sol comprising hydrophobic particles and a continuous phase,
- wherein the particles comprise
- from 0.1 to 99.9 wt % of at least one saturated or unsaturated, monocarboxylic aliphatic hydrocarbon or derivative thereof having a linear, branched, and/or cyclic chain of from 8 and 24 carbon atoms, a dimer thereof, a trimer thereof, or mixtures thereof based upon the total weight of the particle;
- from 0.1 to 99.9 wt % of at least one rosin acid compound selected from the group consisting of natural resin-based acids obtained from residues of distillation of natural oils, amine carboxylates and ester and nitrile compounds of these acids based upon the total weight of the particle;
- and
- not more than 60 wt % of unsaponifiable material based upon the total weight of the particle;
- with b) a partial or full foam comprising water.

A method of inhibiting, reducing, and/or preventing the presence of foam in a media, comprising
- contacting a) a partial or full dispersion, emulsion, suspension, or sol comprising hydrophobic particles and a continuous phase,
- wherein the particles comprise
- from 0.1 to 99.9 wt % of at least one saturated or unsaturated, monocarboxylic aliphatic hydrocarbon or derivative thereof having a linear, branched, and/or cyclic chain of from 8 and 24 carbon atoms, a dimer thereof, a trimer thereof, or mixtures thereof based upon the total weight of the particle;
- from 0.1 to 99.9 wt % of at least one rosin acid compound selected from the group consisting of natural resin-based acids obtained from residues of distillation of natural oils, amine carboxylates and ester and nitrile compounds of these acids based upon the total weight of the particle;
- and
- not more than 60 wt % of unsaponifiable material based upon the total weight of the particle;
- with b) a partial or full foam comprising water.
- wherein the amount of foam present in the media is reduced by at least 5% relative to the amount of foam present in the media when a) is not contacted with b).
