Amines and amine derivatives that improve the buffering range, and/or reduce the chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules to form polyamines with differing pKa's extend the buffering range resulting in polyamines that have the same pKa yields a greater buffering capacity. Derivatives that result in zwitterionic buffers improve yield by allowing a greater range of stability.

The present invention addresses the problem of providing a novel additive for surface activation and an emulsion composition using same, in which an excellent emulsion stability is obtained. The present invention also addresses the problem of improving the usage feel in a cosmetic and the lubrication performance in a lubricant. This additive for surface activation is one in which the following components (A) and (B) are compounded. (A) An amine or ammonium compound having a hydroxyaliphatic hydrocarbon group that contains one or more hydroxy groups and optionally contains an oxygen atom unassociated with the hydroxy groups; and (B) an unsaturated or branched aliphatic acid having 8 to 22 carbon atoms or a salt thereof. In addition, this emulsion composition is one in which the above additive has been added.

A carbon dioxide absorbent composition is described, including (i) a liquid, nonaqueous silicon-based material, functionalized with one or more groups that either reversibly react with CO.sub.2 or have a high-affinity for CO.sub.2, and (ii) a hydroxy-containing solvent that is capable of dissolving both the silicon-based material and a reaction product of the silicon-based material and CO.sub.2. The absorbent may be utilized in methods to reduce carbon dioxide in an exhaust gas, and finds particular utility in power plants.

An absorbent solution is provided for removing acid compounds contained in a gaseous effluent and a method of removing acid compounds contained in a gaseous effluent contacts the gaseous effluent with the absorbent solution. The absorbent solution includes at least one of the following two nitrogen compounds belonging to the family of tertiary diamines: 1-dimethylamino-3-(2-dimethylaminoethoxy)-2-propanol ##STR00001## 1,1-oxybis[3-(dimethylamino)-2-propanol] ##STR00002##
and water.
