Light Kaolin IP/BP/USP/JP

Appearance: White, fine, odorless powder. Chemical Name: Kaolin, also known as Hydrated Aluminum Silicate. Chemical Formula: AlSiOï(OH)ï (Hydrated Aluminum Silicate). Identification: Solubility: Insoluble in water and alcohol. Reaction with Sulfuric Acid: Produces a gel-like consistency. pH: pH Range: 5.0 to 7.0 (in a 5% aqueous suspension). Moisture Content: <14% (depending on the grade). Heavy Metals: Lead (Pb): <10 ppm. Arsenic (As): <2 ppm. Cadmium (Cd): <1 ppm (depending on the grade). Particle Size: <75 microns (ensures uniform dispersion and effective use in formulations). Loss on Drying: <12%. Applications: Pharmaceuticals: Used as an adsorbent in the treatment of diarrhea, a binding agent in tablets, and a suspending agent in liquid formulations. Cosmetics: Used as a thickening agent in creams, lotions, and powders. Food Industry: Used in small amounts as a clarifying agent and in dietary supplements. Storage: Store in a cool, dry place, away from moisture and sunlight.

Appearance: White, fine powder with a smooth texture. No visible foreign matter or contamination. Identification: Chemical name: Kaolinite (Hydrated Aluminum Silicate). Infrared spectroscopy or X-ray diffraction can be used for identification. Purity: Must contain at least 90% kaolinite. Free from toxic contaminants such as heavy metals, pathogens, and other harmful substances. Physical Properties: Particle Size: Fine, ensuring smooth texture suitable for pharmaceutical use. Moisture Content: Typically less than 14% (by weight). pH: Between 5.0 to 7.0 (in a 5% aqueous suspension). Ash Content: Should meet the specified limit for the material. Heavy Metals: Lead (Pb): Less than 10 ppm. Arsenic (As): Less than 2 ppm. Mercury (Hg) and Cadmium (Cd): Below specified limits (usually less than 1 ppm). Microbial Limits: Must be free from pathogenic microorganisms. Standard limits for Total Aerobic Microbial Count, Yeast and Mould Count, and E. coli. Solubility: Insoluble in water and alcohol. Loss on Drying: Typically, the loss on drying (moisture content) should be less than 14%. Test for Impurities: Free from extraneous matter, including sand, dirt, and other non-kaolinite impurities. Storage: Store in a cool, dry place away from moisture and direct sunlight. Applications: Kaolin JP is used in pharmaceutical formulations, particularly for gastrointestinal treatments (such as anti-diarrheal formulations), topical medications, and as a suspending agent in liquid formulations. It is also used in cosmetics (e.g., face masks, powders) due to its absorbent and gentle properties on the skin.
