Abstract: The present invention concerns a method for preparing glycerol ether or glycol ether comprising the reaction of a compound of formula (II) with a compound of formula (III) in the presence of a heterogeneous acid catalyst of formulas (II) and (III).

Abstract: A cosmetic applicator comprises a body defining a handle, the body being arranged to receive the cosmetic product, a rotatable applicator element attached to a distal end of the body, the applicator element extending transversely relative to the body and being located proximate the cosmetic product, and a driving arrangement to rotate the applicator element, thereby loading the cosmetic product for subsequent application. In an embodiment, the body is elongate so as to define a longitudinal axis, with the applicator element extending perpendicular to the longitudinal axis of the body. In an embodiment, the cosmetic applicator comprises an actuating arrangement to allow a user to selectively control the position of the cosmetic product with respect to the applicator element, thereby allowing a controlled quantity of cosmetic product to be loaded onto the applicator element.

Abstract: A method for detecting PrP in a biological human or animal sample that may contain said PrP. The method is characterized in that it uses a molecule containing at least one positive charge and/or at least one glycosidic bond and a ligand other than a protein ligand selected from macrocyclic ligands and glycosaminoglycans.

Abstract: The invention relates to a method for detecting PrP in a biological human or animal sample that may contain PrP. The inventive method is characterised in that it uses a molecule containing at least one positive charge and/or at least one osidic bond and a ligand other than a proteinic ligand selected from macrocyclic ligands and glycosaminoglycanes.
