PROCESS FOR REDUCING MALODOURS

摘要

The use of 2-amino-1,3-propanediol and/or substituted 2-amino-1,3-propanediol for degradation of malodours caused by the presence of acids, thiols, sulphides, amines, aromatics, alcohols and/or heteroaromatics is described. By addition of 2-amino-1,3-propanediol and/or substituted 2-amino-1,3-propanediol to the ambient air or, for example, incorporated into washing compositions, it is possible to reduce corresponding malodours.

主权项

1. A method for degrading off-odors brought about by the presence of acids, thiols, sulfides, amines, aromatics, alcohols, and/or heteroaromatics on hard and/or soft surfaces or room air, wherein 2-amino-1,3-propanediol and/or substituted 2-amino-1,3-propanediol in accordance with formula (I)where in this formula the residues R1, R2, and R3, mutually independently in each case, denote hydrogen or hydrocarbon residues that can be acyclic or cyclic, substituted or unsubstituted, branched or unbranched, and saturated or unsaturated, is delivered onto the hard and/or soft surface or into the room air.
