摘要：
The present invention relates to the field of perfumery and flavor. More particularly, it concerns cleavable surfactants of formula (I) having a total hydrophilic-lipophilic balance (HLB) comprised between 3 and 18 and wherein A is a group capable of releasing a flavor or fragrance aldehyde of formula (R1)CHO or a flavor or fragrance ketone of formula (R1)(R2)CO and is of formula (II) wherein the wavy line indicates the location of the bond between L and A； R1 and R2 represent independently from each other a hydrogen atom or a linear saturated or unsaturated C1-C18 hydrocarbon group, optionally substituted with one to three oxygen atoms in the form of a hydroxyl, carbonyl, ether or ester group, or a branched or cyclic, saturated or unsaturated C3-C18 hydrocarbon group, optionally substituted with one to three oxygen atoms in the form of a hydroxyl, carbonyl, ether or ester group or R1 and R2, when taken together, represent a C4-18 linear, branched or cyclic alkanediyl group, optionally substituted with one to three oxygen atoms in the form of a hydroxyl, carbonyl, ether or ester group, provided that at least one of the R1 or R2 groups has 6 consecutive carbon atoms and that both R1 and R2 taken together comprise a maximum of 18 carbon atoms； L is a linear, branched or cyclic, saturated or unsaturated C3 to C40 hydrocarbon group, optionally substituted with one to twelve oxygen atoms in the form of an ether or ester group； and Q is a is a branched, linear, cyclic, saturated or unsaturated C3 to C100 hydrocarbon group different than L, optionally substituted with 1 to 50 oxygen atoms, or with 1 to 50 nitrogen atoms or with 1 to ten sulphur atoms； allowing to solubilize and/or stabilize flavor and fragrance aldehydes and ketones in an aqueous environment and at the same time to control their release by hydrolysis.La présente invention concerne le domaine de la parfumerie et de l'arôme. La présente invention concerne particulièrement des tensioactifs clivables de formul
