A fiber-treating agent including a condensate formed from the following components (A) and (B), and a component (C). A total content of a constituent element derived from the component (A) and a constituent element derived from the component (B) is more than 1 mass %, and a turbidity is 1,000 NTU or less: (A): formaldehyde or a hydrate thereof, (B): triazine or a derivative thereof of formula (1):

##STR00001## where R.sup.1 to R.sup.3 are the same or different, and each represent a hydrogen atom, a hydroxymethylamino group, an amino group, a hydroxy group, a halogen atom, a phenyl group, a linear or branched alkyl group or alkenyl group having 1 or more and 6 or less carbon atoms, or a linear or branched alkoxy group or alkenyloxy group having 1 or more and 6 or less carbon atoms, and (C): water.

The invention relates to a method for releasing an aldehyde or ketone of formula (2) by allowing a hydrolase to act on a compound of formula (1). The compound of formula (1) is used as a flavor or fragrance precursor. In formula (1), each of R.sup.1, R.sup.2 and R.sup.3 independently represents a hydrogen atom, an alkyl group which may have a substituent, a cycloalkyl group which may have a substituent, an alkenyl group which may have a substituent, an aryl group which may have a substituent, or an aralkyl group which may have a substituent. R.sup.1 and R.sup.2 or R.sup.1 and R.sup.3 may form a ring. Ar represents an aryl group which may have a substituent. In formula (2), R.sup.1, R.sup.2 and R.sup.3 have the same definitions as those in formula (1). R.sup.1 and R.sup.2 or R.sup.1 and R.sup.3 may form a ring:
