20250326884 · 2025-10-23 ·

A composition includes at least one of: (a) an amino acid isocyanate adduct of Formula I:

##STR00001##

and salts thereof, and (b) an amino acid epoxide adduct of Formula II:

##STR00002##

and salts thereof. R.sub.1 is a moiety of a monomer or prepolymer including two NCO functional groups, which have reacted to form urea linkages; R.sub.2 is a moiety of a monomer or prepolymer including two glycidyl ether epoxide functional groups, which have reacted to form amino alcohol groups; R.sub.6, R.sub.7, R.sub.20 and R.sub.21 are independently (CH.sub.2).sub.n, n is 1-6; R.sub.8, R.sub.9, R.sub.10 and R.sub.11 are independently hydrogen or CH.sub.2X; R.sub.12, R.sub.13, R.sub.14 and R.sub.15 are independently hydrogen, alkali metal cation, or X; R.sub.16 and R.sub.17 are independently hydrogen or X; R.sub.18 and R.sub.19 are independently hydrogen, SiO.sub.3 or X; and each X is independently hydrogen or a substituent. Controlled release particles, consumer products and methods including the composition are also disclosed.
