High-purity kaolin excipient for pharmaceutical formulations

Sree Sai Mineral Industries supplies a high-purity kaolin used strictly as an inactive pharmaceutical excipient — a filler, carrier and anti-caking agent that supports the physical structure of tablet, topical and oral suspension formulations.

Our kaolin is processed under controlled conditions to deliver consistent particle size, low iron content and reliable purity, with every batch tested in our in-house quality laboratory and issued a Certificate of Analysis. This kaolin carries no therapeutic or medicinal function and is supplied purely for its formulation and excipient properties, subject to the customer's own regulatory qualification.

FAQ's

Pharmaceutical Kaolin Excipient — Common Questions

Kaolin is used as an inactive excipient — a bulking filler, anti-caking agent and carrier — in tablet, topical and oral suspension formulations. It is not an active pharmaceutical ingredient and carries no therapeutic claim.

Our pharma-grade kaolin is processed to a high purity level with tightly controlled iron content and moisture, and every batch is tested in our in-house QC lab against customer specifications before dispatch.

We supply in 25 kg and 50 kg HDPE bags, 1-tonne jumbo (FIBC) bags, and bulk container loading, each accompanied by a Certificate of Analysis.
