    摘要: Compounds having formula (I) in which n is 1, 2 or 3 and R1 to R6 represent, independently, branched or unbranched, substituted or unsubstituted alkyl-, alkenyl-, alkinyl-, cycloalkyl-, cycloalkenyl- or aromatic-radicals or hydrogen wherein these radicals may in addition contain one or more —O— and/or (a)—groups, whereby one or two rings can be built by the combination of the respective R1 to R6 and this/these ring(s) can be further substituted by an alkyl-group, in which X is either O and R7 represents a radical of an alcohol or phenol R7OH, or X is N and R7 represents the radical of an amine R7′R7″NH, whereby R7′ and R7″ represent independently, branched or unbranched, substituted or unsubstituted alkyl-, alkenyl-, alkinyl-, cycloalkyl-, cycloalkenyl- or aromatic radicals or either R7′R7″ may be hydrogen, whereby the amine is a fragrant amine or the amine has more than 9 C atoms, whereby R7 of the alcohol or phenol and R7′ and/or R7″ of the amine, respectively, may further contain at least one remaining part C(OH)R1R2—CR3R4—(CR5R6)n—CO— of formula (I), are useful as precursors for the delivery of odoriferous and/or antibacterial compounds in cosmetic compositions, cosmetic products, air fresheners, hard surface cleaners or laundry products.

    摘要: The invention relates to fragrance precursors, In particular, the invention relates to the use of several classes of compounds which may act as fragrance precursors, e,g., in cosmetic products such as deodorants and antiperspirants and in laundry products such as detergents and fabric softners. These compounds are odorless, but upon contacting the skin as example, in skin care compositions or in personal care compositions, produce fragrances. The compounds also produce fragrances when used in the presence of lipases, e.g. as used in (laundry) detergents, thus providing a prolongation of the fabric scenting effect. The compounds under consideration are compounds of the formula I: The substituents are defined in the specification.

    摘要: The invention is concerned with the 7R/7S-diastereoisomer mixture of the formula ##STR1## in pure form, essentially free of the corresponding (4R)-isomers. The invention also concerns the 2R/2S-diastereoisomer mixture of the formula ##STR2## in pure form which is useful as an intermediate for producing I. In addition, the invention concerns a process for obtaining I by subjecting II to isochromane ring closure. Odorant compositions containing I and the use of I as an odorant are also described.

    摘要: Organosilicon compounds having at least one unit of the general formula ##STR1## in which R represents alkyl, R' is a divalent alkylene, oxyalkylene, alkenylene or oxyalkenylene, Z represents an alkyl, alkoxy or hydroxyl group, a has a value of 0, 1, 2 or 3 and c is 0 to 1, wherein at least one of Z and R' is linked to the multivalent aryl group via an ether linkage, are useful for absorbing UV radiation. Especially if polymeric (with e.g. diorganosiloxane units) they can be incorporated in sunscreen preparations to improve their substantivity to the skin. A process for preparing the compounds is also disclosed.
