1. A process for obtaining a mixture of C4-C8 alkyl monoether of saccharide and/or of saccharide derivative and of C9-C18 alkyl monoether of saccharide and/or of saccharide derivative, said saccharide derivative being a glycosylated and/or hydrogenated and/or dehydrated saccharide, said process comprising:

  • a) a first step of acetalization or trans-acetalization of a saccharide, of saccharide derivative or of mixtures thereof with a C4-C8 aliphatic aldehyde or the acetal thereof,b) a second consecutive or simultaneous step of acetalization or trans-acetalization of the product obtained in a), of the saccharide, of the saccharide derivative or of mixtures thereof, with a C9 to C18 aliphatic aldehyde or the acetal thereof,c) a step of catalytic hydrogenolysis of the acetals of saccharide and/or of saccharide derivative obtained in b), andd) a step of recovery of a mixture of C4-C8 alkyl monoether of saccharide and/or of saccharide derivative and of C9-C18 alkyl monoether of saccharide and/or of saccharide derivative.
