Zusammenfassung:	The invention relates to the use of solid betaine for de-icing and/or preventing slipperiness. The solid betaine comprises at least one non-betaine compound affecting water and/or moisture movement in said solid betaine. The invention further relates to a process for the manufacture of solid betaine. A suspension comprising betaine crystals is prepared from a feed liquid and the betaine crystals are separated and washed. The amount of wash liquid is adjusted in order to leave 0.5 to 10 w-% of at least one non-betaine compound in said solid betaine.
