Heavy Kaolin IP/BP/EP

Heavy Kaolin BP

Chemical Name: Hydrated Aluminum Silicate (AlSiOï(OH)ï). Appearance: A fine, white or off-white powder, odorless and tasteless. Purity Requirements: Must primarily consist of kaolin (hydrated aluminum silicate). Impurities such as heavy metals, arsenic, lead, and iron must be within specified limits. Moisture Content: The loss on drying is usually specified, with limits typically around 10-15% moisture. pH: The pH of an aqueous suspension (usually at 1-2% w/v) is typically 4.5 - 5.5 (slightly acidic). Microscopy: It should meet specified requirements for microscopic examination, which can verify the presence of kaolin and the absence of contaminants. Microbial Contamination: Must comply with limits for total microbial count, and there should be no pathogenic organisms present. Heavy Metal Content: Limits on heavy metals, typically not exceeding 20 ppm for lead and other metals as specified by BP standards. Ash Content: Ash value is typically specified to check the inorganic content, generally around <1%. Application: Primarily used in pharmaceutical formulations for its absorbent properties (e.g., in antacid preparations and diarrhea treatments) and for topical use in cosmetics.
