A composition for purifying a liquid, such as used cooking oil, unrefined edible oils, or biodiesel fuel, that comprises at least one purifying material, such, as magnesium silicate, and at least one binder material that is a solid or a semi-solid at room temperature, or is water or a glycol. When the composition is placed in a liquid, and the liquid is heated, the solid composition disintegrates and the at least one purifying material is released in the liquid. Such composition minimizes or eliminates contact with the dust associated with solid adsorbent materials, and provides for a controlled release of the at least one purifying material into the liquid to be purified. L'invention concerne une composition pour purifier un liquide, tel qu'une huile de cuisson usagée, des huiles comestibles non raffinées, ou du carburant biodiesel, qui comprend au moins un matériau de purification, tel que du silicate de magnésium, et au moins un matériau liant qui est un solide ou un semi-solide à température ambiante, ou est de l'eau ou un glycol. Lorsque la composition est placée dans un liquide, et lorsque le liquide est chauffé, la composition solide se désintègre et l'au moins un matériau de purification est libéré dans le liquide. Une telle composition réduit au minimum ou élimine le contact avec la poussière associée à des matériaux adsorbants solides, et permet une libération contrôlée de l'au moins un matériau de purification dans le liquide à purifier.
