B. Effectiveness of the Composition

Use of Solid Phase Microextraction (SPME) to Demonstrate Malodor Material Reduction in the Presence of the Above-Described MOC Composition

[0079]First of all, a 20% solution of butylamine in EtOH was prepared. 0.005 ml of this solution were transferred with a pipette onto a watch glass at the bottom of two 3 L desiccators. 3 g of the MOC composition prepared in part A were placed on a cellulose pad in a Petri-dish, which was placed in one of the desiccator, on a tray above the watch glass containing the butylamine solution. The desiccator...

Abstract

The present invention relates to the field of perfumery and more particularly to the field of malodor counteractancy. In particular, it relates to a 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.

Description

TECHNICAL FIELD[0001]The present invention relates to the field of perfumery and more particularly to the field of malodor counteractancy. In particular, it relates to 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.BACKGROUND OF THE INVENTION[0002]The prior art richness in reports of methods and compositions to counteract and / or mask malodors is such that a complete review of all the methods and compositions prior reported in this context is impossible here. It is clear however that there still exists a need to continue searching alternative ways of solving the malodor problem, as evidenced by the constant publications in this field.[0003]Some prior publications relate to the use of aldehydes, ketones and / or alcohols in deodorizing compositions in order to neutralize malodors.
