Abstract

The present invention relates to a composition comprising: a) at least one primary, secondary or tertiary amine and b) at least one agent which masks the odor of said at least one amine, said at least one odor-masking agent comprising at least one ether (b1), optionally, but preferably, at least one terpene and/or one terpenoid (b2) and optionally, but preferably, at least one oxime (b3). The invention also relates to the use of an odor-masking agent in order to mask the odor of at least one amine.

First claim

The invention claimed is:

1. A composition, comprising:
(a) at least 90% by weight of at least one primary, secondary or tertiary amine represented by formula (I), relative to the total weight of the composition,

wherein
R 1 , R 2 and R 3 , which may be identical or different, are selected independently of one another from a hydrogen atom, a linear or branched alkyl radical comprising from 1 to 12 carbon atoms, or a cycloalkyl radical comprising from 3 to 12 carbon atoms, or
two of the substituents selected from R 1 , R 2 and R 3 , together and with the nitrogen atom to which they are bonded, form a ring structure comprising from 2 to 12 carbon atoms, and optionally comprising one or more heteroatoms selected from oxygen, nitrogen, sulfur or phosphorus, and being optionally substituted with one or more functional groups selected from hydroxyl, alkoxy, alkylcarbonyl, alkoxycarbonyl, benzyl, fluorine, chlorine, bromine, iodine, sulfur, phosphorus or nitrogen, and
at least one of is R 1 , R 2 and R 3 is not hydrogen; and
(b) an odor-masking agent,

wherein
the composition comprises at most 10% by weight of the odor-masking agent, relative to the total weight of the composition; and
the odor-masking agent comprises at least one ether represented by formula (b1):
R 4 —O—R 5   (b1)

wherein
R 4 and R 5 , which may be identical or different, are selected independently of one another from a linear or branched alkyl radical comprising from 1 to 12 carbon atoms, a cycloalkyl radical comprising from 3 to 12 carbon atoms, an alkenyl radical comprising from 2 to 12 carbon atoms, a cycloalkenyl radical comprising from 3 to 12 carbon atoms, a phenyl radical or a benzyl radical, or
R 4 and R 5 , together and with the oxygen atom to which they are bonded, form a ring structure comprising from 3 to 20 atoms, optionally comprising one or more heteroatoms selected from oxygen, nitrogen, sulfur and phosphorus, wherein the ring structure is optionally substituted with one or more groups selected from hydroxyl, alkoxy, alkylcarbonyl, alkoxycarbonyl, phenyl, benzyl, fluorine, chlorine, bromine, iodine, sulfur, phosphorus or nitrogen.

2. The composition of claim 1 , wherein the odor-masking agent further comprises:
(b2) at least one terpene and/or one terpenoid.

3. The composition of claim 1 , wherein the odor-masking agent further comprises:
at least one oxime represented by formula (b3):

wherein
R 6 is selected from a linear or branched alkyl radical comprising from 1 to 24 carbon atoms, a cycloalkyl radical comprising from 3 to 24 carbon atoms, an alkenyl radical comprising from 2 to 24 carbon atoms, a cycloalkenyl radical comprising from 3 to 24 carbon atoms, a phenyl radical or a benzyl radical, and R 7 is selected from a hydrogen atom, a linear or branched alkyl radical comprising from 1 to 24 carbon atoms, a cycloalkyl radical comprising from 3 to 24 carbon atoms, an alkenyl radical comprising from 2 to 24 carbon atoms, a cycloalkenyl radical comprising from 3 to 24 carbon atoms, a phenyl radical or a benzyl radical, or
R 6 and R 7 , together and with the carbon atom to which they are bonded, form a ring structure comprising from 3 to 20 atoms, and optionally comprising one or more heteroatoms selected from oxygen, nitrogen, sulfur or phosphorus, wherein the ring structure is optionally substituted with one or more groups selected from hydroxyl, alkoxy, phenyl, benzyl, fluorine, chlorine, bromine, iodine, sulfur, phosphorus or nitrogen.
