Cleavable surfactant

A compound of formula

• having a total hydrophilic-lipophilic balance comprised between 3 and 18 being calculated using the Effective Chain Length model 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
• 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 OC6H4CR32CR32 group or a (OCH2CHR3)q group, wherein R3 represents a hydrogen atom or a methyl group and q is an integer varying between 3 and 10;
• and
• Q is a polyimine, a poly(ethylene oxide), a poly(propylene oxide), a polypeptide, or a polysaccharide.
