An enzyme-mediated method for the production of 3a-ethyl-6,6,9a-trimethyldodecahydronaphtho[2,1-b]furan, the products of said method, and uses of said products.

An encapsulated perfume composition comprising malodour-counteracting perfume ingredients.

The present invention pertains to novel (alkoxymethylene)octahydro-1H-4,7-methanoindene compounds and their unexpected advantageous use thereof in enhancing, improving or modifying the fragrance of perfumes, colognes, toilet waters, fabric care products, personal products, and the like.

Disclosed is a cyclopropanation process comprising the step of reacting an alkene compound having at least one carbon-carbon double bond with at least one dihaloalkane. The reaction is carried out in the presence of (i) particulate metal Zn, (ii) catalytically effective amount of particulate metal Cu or a salt thereof, (iii) at least one haloalkylsilane, and (iv) at least one solvent.

5,9-dimethyl-9-hydroxy-decen-4-al, having the formula (I) ##STR00001##

The present invention relates to personal care compositions comprising malodor reduction compositions and methods of making and using such personal care compositions. Such personal care compositions comprising the malodor control technologies disclosed herein provide malodor control without leaving an undesireable scent and when perfume is used to scent such compositions, such scent is not unduely altered by the malodor control technology.
