The present invention relates to the field of perfumery. More particularly, it concerns malodor masking compositions and/or ingredients, as well as method for counteracting or masking malodors and perfuming compositions having odor masking properties.

Macrocyclic ketone as malodor counteracting ingredient

The present invention relates to the field of perfumery and more particularly to the field of malodor counteractancy. In particular, it relates to a method for application of malodor counteracting (MOC) compositions capable of neutralizing in an efficient manner, through chemical reactions, malodors of a large variety of origins and which can be encountered in the air, on textiles, bathroom or kitchen surfaces, and the like. The composition may be applied as is or in the form of a perfuming composition or in a consumer product or article containing the compound or perfume composition.

Malodor counteracting compositions and method for their use

The present invention is drawn to a device for perfuming ambient air or closed spaces.An active volatile substance, like a perfume, an insect repellent or a deodorizing or sanitizing agent, is evaporated from a device.Thesaiddevice comprises water or an appropriate hydrophilic solvent containingsaid volatiletheactiveingredient and an absorbing material chosen from superabsorbents, starch based systems, chemically modified cellulose and natural gum andvolatile substance and a superabsorbent substancewhichareiscapable of forming a gel with water orsaidthehydrophilic solvent, both components being adapted to be mixed with each other in order to achieve the diffusion ofsaidthe activevolatileingredientsubstancefrom thesaidgel. The components are mixed with each other to formsaidthegel from which theperfume or a deodorizing or sanitizing agent, or an insect repellent,active volatile substancediffuses uniformly and over a prolonged period of time into the surrounding air.

Gel type vapor release device

The present invention is drawn to a device for perfuming ambient air or closed spaces. The said device comprises water or an appropriate hydrophilic solvent containing said volatile active ingredient and an absorbing material chosen from superabsorbents, starch based systems, chemically modified cellulose and natural gum and which are capable of forming a gel with water or said hydrophilic solvent, both components being adapted to be mixed with each other in order to achieve the diffusion of said volatile ingredient from the said gel. The components are mixed with each other to form said gel from which the perfume or a deodorizing or sanitizing agent, or an insect repellent, diffuses uniformly and over a prolonged period of time into the surrounding air.
