Determination des deplacements chimiques de 13 C et des effets isotopiques du deuterium。Mise en evidence des interacts non liees sur la distribution decharge。异分异构体 Z 和 E
The present invention concerns compound of formula (I) in the form of any one of its stereoisomers or as a mixture thereof, and wherein Q group represents a —CH=CH—CH3 group or a —C≡C—CH3 group. The use as a perfuming ingredient of the invention's compound and the invention's compound as part of a perfuming composition or of a perfuming consumer product are also part of the present invention.
Described herein is a compound of formula (I)
in the form of any one of its stereoisomers or a mixture thereof, and where the Q group represents a —CH═CH—CH3 group or a —C≡C—CH3 group. Also described herein is a method of using a compound of formula (I), the method including using the compound of formula (I) as part of a perfuming composition or as part of a perfumed consumer product.
A responsive microgel is provided which responds volumetrically and reversibly to a change in one or more aqueous conditions selected from the group consisting of (temperature, pH, and ionic conditions) comprised of an ionizable network of covalently cross-linked homopolymeric ionizable monomers wherein the ionizable network is covalently attached to an amphiphilic copolymer to form a plurality of ‘dangling chains’ and wherein the ‘dangling chains’ of amphiphilic copolymer form immobile micelle-like aggregates in aqueous solution. A responsive microgel is further provided that comprises at least one therapeutic entity and delivers a substantially linear and sustained release of the therapeutic entity under physiological conditions.
