Abstract (en)
[origin: WO2004099117A1] The invention relates to a method for producing a benzoate by reacting a benzoic acid constituent, selected from a benzoic acid and a benzoic acid ester, with alcohol in the presence of a catalyst. Tin (II) oxide, which is combined with a phosphorous (I) compound, in particular phosphoric (I) acid or a salt thereof, is used as the catalyst. The method is particularly suitable for the esterification of benzoic acid with fatty alcohols or hydroxy-fatty alcohols. The resultant products can be used as constituents in cosmetic preparations.
