Claim:
A method for scavenging airborne formaldehyde, the method comprising: providing an article that emits airborne formaldehyde into its environment; contacting the airborne formaldehyde with a formaldehyde scavenger such that the airborne formaldehyde reacts with the formaldehyde scavenger to form a conjugate compound, wherein the formaldehyde scavenger is of the formula I: or salt thereof, in which R A is a bond or is C(R 7 R 8 ); R 1 is H, OH or C 1 -C 6 alkyl; R 2 is H, OH or C 1 -C 6 alkyl; R 3 , R 4 , R 5 , and R 6 are independently H, or C 1 -C 6 alkyl; and R 7 and R 8 are independently H, OH or C 1 -C 6 alkyl; wherein alkyl in R 1 -R 8 is optionally independently substituted with OH, NR 9 R 10 , C 1 -C 6 alkyl, or phenyl, and wherein R 9 and R 10 are independently H or C 1 -C 6 alkyl, provided that if neither R 7 nor R 8 is OH, then at least one of R 1 and R 2 is OH.
