Kind Code:
A
Abstract:
To provide a stable water drop-in-oil-type emulsion defoaming agent composition, comprising a mineral oil and water and containing a fatty amide as an active ingredient of the defoaming agent, which does not change with time such as separation and sedimentation of the active ingredient and deactivation of the active ingredient and further does not cause dispersion of the defoaming ingredient in the whole aqueous phase during use thereof.
In this water drop-in-oil-type emulsion composition comprising a mineral oil and water, fine particles of a fatty amide are contained in the water-in-oil-type emulsion which has been stabilized by using a polyoxyalkylene alkyl ether alicyclic carboxylic ester as an emulsifying agent.
