Investigation of the Release of Bioactive Volatiles from Amphiphilic Multiarm Star-Block Copolymers by Thermogravimetry and Dynamic Headspace Analysis

John Christopher Plummer, Céline Ternat, Harm-Anton Klok

Amphiphilic multiarm star-block copolymers with a hydrophobic inner and a hydrophilic outer shell have been used to encapsulate hydrophobic bioactive volatiles in aqueous media under realistic application conditions. The release rates of the bioactive comp ...

Amphiphilic multi-arm star-block copolymers for encapsulation of fragrance molecules

John Christopher Plummer, Céline Ternat, Harm-Anton Klok

Novel amphiphilic multi-arm star-block copolymers with a hyperbranched core, a hydrophobic inner shell, and a hydrophilic outer shell have been prepared from a commercial hyperbranched polyester macroinitiator by ring-opening polymerization of -caprolacton ...

NMR diffusion and relaxation studies of the encapsulation of fragrances by amphiphilic multiarm star block copolymers

John Christopher Plummer, Céline Ternat, Harm-Anton Klok

Self-diffusion NMR spectroscopy and relaxometry have been employed to study fragrance encapsulation in water-soluble, amphiphilic star block copolymers. Diffusion coefficients of four different fragrance molecules in the free form and in the presence of th ...

Design of amphiphilic nanocapsules based on hyperbranched star-block copolymers for the encapsulation and the controlled release of olfactory compounds

Céline Ternat

Effective encapsulation of small, volatile, weakly water-soluble molecules such as flavors and fragrances is necessary to protect them from degradation, to increase their lifetime, and to improve their water dispersion and fixation depending on the substra ...

Water-soluble, unimolecular containers based on amphiphilic multiarm star block copolymers

John Christopher Plummer, Céline Ternat, Harm-Anton Klok

A new class of water-soluble, amphiphilic star block copolymers with a large number of arms was prepared by sequential atom transfer radical polymerization (ATRP) of n-butyl methacrylate (BMA) and poly-(ethylene glycol) methyl ether methacrylate (PEGMA). A ...
