An absorbent composition including an amino-siloxane is presented. The amino- siloxane includes structure (I): wherein R1 is independently at each occurrence a C1-C6 aliphatic or aromatic radical; R2 is independently at each occurrence a C2-C10 aliphatic or aromatic radical; and R3 is independently at each occurrence a C1-C18 aliphatic or aromatic radical or R4, wherein R4 comprises structure (II): wherein X is independently at each occurrence an electron donating group; and n is at least 1. Methods of reducing an amount of carbon dioxide in a process stream using the absorbent composition are also presented.
