Compounds having protected hydroxy groups

The present invention relates to compounds with protected hydroxy groups of formula (I) These compounds are precursors for organoleptic agents, such as fragrances, and masking agents and for antimicrobial agents. When activated, the compounds of formula (I) are cleaved and form one or more organoleptic and/or antimicrobial compounds.

When activated, the compounds of formula (I) are cleaved and form one or more organoleptic and/or antimicrobial compounds.

Precursor compounds

The compounds of the formula I are precursors for organoleptic and antimicrobial compounds. The latter are generated in the presence of skin bacteria, enzymes or acidic or alkaline conditions. One precursor molecule can provide one or more different compounds.

Fragrance precursor compounds

Organosiloxane fragrance precursor compounds having at least one organosiloxane unit of the formula or a mixture thereof and if any other siloxane unit(s) in the said organosiloxanes being present this/these is/are of formula wherein R represents a substituted or unsubstituted C1-8alkyl group or a substituted or unsubstituted aryl group; R″ represents a hydrogen atom, a monovalent C1-8hydrocarbon group or a monovalent C1-8halogenated hydrocarbon group; R1represents a hydrogen atom or a substituted or unsubstituted C1-8alkyl group or a substituted or unsubstituted aryl group or a bond connecting CR1and CR3; R3represents a hydrogen atom or a substituted or unsubstituted C1-8alkyl group or a substituted or unsubstituted aryl group; represents (CR42)nwhereby R4represents a substituted or unsubstituted C1-8alkyl group or a substituted or unsubstituted aryl group or a hydrogen atom and whereby n is from 0-20 and each R4is the same or different; OR2represents the residue of an olfactive alcohol or of the enol form of an olfactive aldehyde or olfactive ketone; is 0, 1 or 2; and is 0, 1, 2 or 3. The compounds can be used in the manufacture of odorant compositions used in the preparation of cosmetic and laundry products.

Process for perfuming textiles

We describe a process for perfuming fabrics washed in the presence of a lipase-containing detergent and, optionally, subsequently treated with a fabric softener, said process being characterized in that said detergent and/or said fabric softener contains a compound of formula STR1 wherein a. R represents a radical derived from an fragrant alcohol of formula ROH and Y represents a C7 to C24 linear or branched, saturated or unsaturated alkyl radical, or a --(CH2)n COOR group wherein R is defined as above and n is an integer from 0 to 6; or p1 b. Y represents a C7 to C24 linear or branched, saturated or unsaturated alkyl radical and R represents a group of formula STR2 wherein, either R1 represents hydrogen and R2 represents an alkylidene radical derived from a fragrant aldehyde of formula STR3 or R2 represents an alkylidene radical and R1 an alkyl radical, R1 and R2 being then derived from an fragrant ketone of formula STR4 and, optionally, being part of a ring such as indicated by the dotted line which contains 5 to 18 carbon atoms and can be substituted. The process has the advantage of providing an effect of slow diffusion ("slow release") of said fragrant alcohol, aldehyde or ketone, thus prolonging the odor effect of the latter on fabrics.
