Abstract: Described herein is a process for a preparation of microcapsules based on cleavable multi-alcohols. Also described herein are cleavable multi-alcohol-based microcapsules. Also described herein are perfuming compositions and consumer products including such capsules, in particular perfumed consumer products in the form of home care or personal care products.

Abstract: The present invention relates to polyamide microcapsules. A process for the preparation of polyamide microcapsules is also an object of the invention. Perfuming compositions and consumer products comprising said microcapsules, in particular perfumed consumer products in the form of home care or personal care products, are also part of the invention.

Abstract: The present invention relates to the field of perfumery. More particularly, it relates to compounds of formula (I) that are able to provide a long-lasting or substantive odor to the environment. Moreover, the present invention relates to a method of imparting a long-lasting odor to environment or to surfaces, such as hard surfaces, fabric, skin or hair. Furthermore, the present invention relates to the use of said compounds in perfumery, as well as the perfuming compositions or perfumed articles comprising the invention’s compounds.

Abstract: The present invention relates to water-dispersable microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile polymer comprising ?-ketoacid or ?-ketoester group capable of generating a gas upon exposure to light. The gas is able to cause an extension or the breaking of the microcapsule allowing the release of the oil phase and thus increasing the long-lastingness of the odor perception. The present invention concerns also the use of said microcapsules in perfumery as well as perfuming compositions or perfumed articles comprising the invention's microcapsules to provide a prolonged release of fragrant molecules.

Abstract: Compounds consisting of indan derivatives of the formula: ##STR1## Wherein X or Y represents an aldehyde or an acetal group and the other represents a hydrogen, and R represents a hydrogen or a methyl group and the t-butyl group is at the 5 or 6 position of the phenyl ring. Where these compounds are useful as perfuming ingredients for the preparation of perfuming compositions and perfumed articles to which they impart floral odor notes.

Abstract: The compounds of formulaa. ##STR1## wherein symbol X represents a --CHO group or a group of formula ##STR2## in which symbols R', taken separately, represent each a C.sub.1 to C.sub.4, linear or branched, saturated or unsaturated alkyl radical, or taken together represent a substituted or unsubstituted C.sub.2 to C.sub.4 alkylene radical; symbol R.sup.2 represents a hydrogen atom or a methyl radical; and R.sup.1 and R.sup.3 are different and represent each a hydrogen atom or a methyl radical;or of formulab. ##STR3## wherein the tert-butyl radical is located in position 5 or 6 of the aromatic ring and, either Y represents hydrogen and X and R.sup.2 have the meaning indicated above, or X and R.sup.2 represent each a hydrogen atom and Y represents a --CH.sub.2 CHO group or a group of formula ##STR4## in which R' is defined as in a.; or of formulac. ##STR5## wherein X and R.sup.
