The invention relates to new oil gelling polyurethanes useful for preparing clear gels in organic media (oils, solvents) and to a process for their preparation. The invention also relates to the gels formed from these gelling polyurethanes and to compositions containing them, in particular cosmetic compositions.

Polyurethane gelling agent

Cleavable surfactants of formula (I) having a total hydrophilic-lipophilic balance (HLB) of between 3 and 18 and wherein A is a group capable of releasing a flavor or fragrance aldehyde of formula (R)CHO or a flavor or fragrance ketone of formula (R)(R)CO and is of formula wherein the wavy line indicates the location of the bond between L and A; Rand Rrepresent a hydrogen atom or a saturated or unsaturated C-Chydrocarbon group, provided that at least one of the Ror Rgroups has 6 consecutive carbon atoms and that both Rand Rtaken together comprise a maximum of 18 carbon atoms; and L is a linear, branched or cyclic, saturated or unsaturated Cto Chydrocarbon group. These surfactants 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.
