Method of deodorizing a formulation containing at least one compound bearing a thiol group and deodorized formulation thus obtained

Method of deodorizing a formulation containing at least one compound bearing a thiol group and deodorized formulation thus obtained

Method of deodorizing in order to remove malodorous compounds which are present in or formed from a liquid formulation containing at least one compound bearing a thiol functional group, of formula: HS-A-Y-B (I) in which: 1) the liquid formulation is placed in contact with an inert membrane which is...

Zusammenfassung:Method of deodorizing in order to remove malodorous compounds which are present in or formed from a liquid formulation containing at least one compound bearing a thiol functional group, of formula: HS-A-Y-B (I) in which: 1) the liquid formulation is placed in contact with an inert membrane which is permeable to the malodorous compounds and impermeable to the compound(s) of formula (I); and 2) the malodorous compounds which have passed through the membrane are placed in contact with at least one chemical substance reacting with the said malodorous compounds and/or with at least one physical adsorption substance having a large specific surface area which binds the said malodorous compounds.
