  • Diatomaceous earth composition with a low endotoxin content
    Patent number: 11911741
    Abstract: The present invention relates to a diatomaceous earth composition with a low endotoxin content, comprising an agglomerated mixture of calcined diatomaceous earth particles and water, wherein the mass ratio of calcined diatomaceous earth particles and water is in the range of 1:1.0 to 1:2.0, and wherein the endotoxin content of the diatomaceous earth composition is equal to or less than 0.5 EU/mL. In a further aspect, the present invention relates to a method for producing the diatomaceous earth composition with a low endotoxin content. In another aspect, the present invention relates to the use of the diatomaceous earth composition with a low endotoxin content as a precoat agent for the precoat filtration in biopharmaceutical applications.
