Patent number: 11344493Abstract: 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 (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 a hydrogen atom or a saturated or unsaturated C1-C18 hydrocarbon 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; and L is a linear, branched or cyclic, saturated or unsaturated C3 to C40 hydrocarbon 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.Type: GrantFiled: January 22, 2018Date of Patent: May 31, 2022Assignee: FIRMENICH SAInventors: Eric Lutz, Nicolas Giuseppone, Andreas Herrmann, Vera Tchakalova, Daniel Benczedi

Patent number: 10894934Abstract: The present invention relates to the field of liquid solubilizing systems. More specifically, the present invention relates to a ringing gel composition, one that is a self-thickened composition having a viscoelastic behavior and a viscosity comprised between 0.1 and 1000 Pa·s at 20° C. at 0.01 s?1 shear rate. The ringing gel has an aqueous phase, a surfactant system of one or more non-ionic surfactant(s), a linker and an oil phase that includes a hydrophobic active ingredient such as a perfume. Consumer products that contain the ringing gel composition, such as a self-thickened liquid laundry scent booster are also part of the present invention.Type: GrantFiled: October 17, 2017Date of Patent: January 19, 2021Assignee: Firmenich SAInventors: Vera Tchakalova, Claudie Bellouard
