The life of acrolein in an aqueous medium is increased by incorporation into the aqueous medium of an effective amount of a buffered acid preferably selected from the class consisting of: (1) H.sub.x A.sub.y, wherein H is hydrogen, A is an inorganic radical, and x and y each are positive integers whereby H and A are valence balanced; (2) RA, wherein R is one of hydrogen, an alkyl or an aryl group, and A is one of CO.sub.2 H, OPO.sub.3 H.sub.2, PO.sub.3 H.sub.2, OSO.sub.3 H, and SO.sub.3 H; and (3) ##STR1## wherein N is zero or a positive integer from one through three, M is a positive integer of at least one, and A is a member selected from the class consisting of CO.sub.2 H, OPO.sub.3 H.sub.2, PO.sub.3 H.sub.2, OSO.sub.3 H, and SO.sub.3 H.
