Abstract: The present invention relates to a malodour counteracting composition as well as to a perfuming composition, a packaging material, and a consumer product comprising the malodour counteracting composition according to the invention. Further, the present invention relates to a method for limiting, reducing or eliminating the perception of malodours associated with plastic materials, comprising the step of adding the malodour counteracting composition according to the invention to a plastic material.

Abstract: The aqueous composition sensorial impact determination method (100), comprises: —a step (105) of inputting at least one fragrant molecule digital identifier, —a step (106) of associating a value representative of a quantity of the associated fragrant molecule to be input, —a step (107) of inputting at least one surfactant molecule digital identifier —a step (110) of computing, by a computing device, a relative concentration of at least one fragrant molecule of the formula in the water phase and in the micellar phase, —a step (115) of retrieving, by a computing device, a liquid-gas partition coefficient of at least one said fragrant molecule, —a step (120) of computing a gas phase concentration of at least one said fragrant molecule, —a step (125) of estimating a psychophysical sensorial intensity for at least one fragrant molecule and —step (130) of outputting the psychophysical sensorial intensity for at least one fragrant molecule of the formula.

Abstract: The present disclosure relates to the field of malodour counteraction. More particularly, it concerns compositions that limit, decrease or eliminate the perception of malodours associated with soaps or soap bases. Such compositions include (i) a malodour antagonist system associated with perfuming ingredients performing as malodour counteractant, and (ii) at least one malodour neutralizing system, in a combination that significantly reduces the perception of malodours associated with soaps or soap bases. Such compositions, their use in combination with delivery systems and their applications in consumer products are objects of the present disclosure.
