Technical and Regulatory Statement

Applications are indicative and subject to the selected grade’s chemical composition, particle-size distribution, surface treatment and processing characteristics. Carbocore’s technical team supports customers in selecting the appropriate grade for their formulation and manufacturing process.

Food, feed, pharmaceutical, cosmetic, medical and potable-water applications require separately evaluated and approved grades. Compliance should not be claimed unless the relevant certification and regulatory documentation are available.

Frequently asked questions

Practical answers for your next material decision.

Discuss your requirement
Does an application listing mean that every grade is suitable?
No. The guide describes potential material uses and selection questions. Confirm suitability through the current grade specification, relevant documents and application trials. Specialty or regulated uses require grade-specific evidence.
