Biodegradable active delivery systems: IFFLast 5 Years Research Landscape

Fragrance and flavor molecules volatilize or degrade prematurely without core-shell architectures that provide controlled release while meeting environmental biodegradability requirements.

What technical problems is IFF addressing in Biodegradable active delivery systems?

Prepolymer shell biodegradation failure

(24)evidences

Isocyanate-functionalized prepolymers often fail to achieve complete environmental degradation while maintaining core-shell integrity for high-impact fragrance ingredients.

Polyurea wall aldehyde instability

(27)evidences

High concentrations of aldehyde fragrances cause premature polyurea wall rupture or chemical degradation in personal care formulations.
