Kaolin USP

Kaolin USP meats current United States Pharmacopoeia regulations and is ideal for use in cosmetic and phansaceutical applications. 

Kaopolite SF la a fine, dry powder that is inert, insoluble, non-hygroscopic, and will not deteriorate in dry storage. Its fine particle size proaotes good suspension in aost liquid systeas, and allows it to pass easily through aerosol valves. Mien incorporated into a product, Kaopolite SF s closely controlled water and oil deaand properties yield consistent and econoaical coapounds. 

Kaopolite SF exhibits low absorptivity and is coapatible with aalne-functional silicones. Mien coabined with harsher abrasives, Kaopolite SF shows a pronounced and beneficial gentling effect.

Kaolin USP hydrated aluBin im silicate is a specially processed fine particle size kaolin designed specifically for use in formulations whore high purity/ bacteria control, and good color are desired. 

Kaolin is practically insoluble in water and organic solvents. It is also insoluble in mineral acids and solutions of alkali hydroxides. Unless sterilized, it may be heavily contaminated with pathogenic microorganisms, such as bacillus anthracis, clostridium tetani and clostridium welchii. It can be sterilized by maintaining the whole at a temperature not less than 160°C for not less than one hour. The primary applieations of Kaolin USP in the pharmaceutical industry are as an adsorbent at eoneentrations of 7.5 to 55%, dusting powders at 25%, and poultices at a level of 53%. Kaolin has also been used as a diluent in tablet and capsule formulations. Kaolin Mixture with Pectin (Gennaro, 1990), an example of a pharmaceutical adsorbent formulation, is shown below. 

In addition to the ICDD, publications dealing solely with the powder patterns of drugs appear occasionally [12-15], In 1971, Sadik et al. pointed out that the identification test for kaolin (in NF XIII) was a test for the presence of aluminum, and therefore both kaolin and bentonite gave positive results [16]. Since the two compounds have different crystal structures, their x-ray diffraction patterns are different, and therefore XPD was recommended for identification of these compounds. In the current edition of USP, the identification of bentonite is based on its powder x-ray pattern [3].

The improvement in stability is achieved by coating the AN particles with a compn consisting of a major amt of a clay (such as attapulgite, kaolin or diatomaceous earth), and a minor amt of an oil-sol alk-earth metal salt of petroleum sulfonic acids (sucb as Ca petroleum sulfonate)]...

The USP 28 describes kaolin as a native hydrated aluminum silicate, powdered and freed from gritty particles by elutriation. The BP 2004 similarly describes light kaolin but additionally states that it contains a suitable dispersing agent. Light kaolin (natural) BP contains no dispersing agent. Heavy kaolin is described in the BP 2004 and PhEur 2005 as a purified, natural hydrated aluminum silicate of variable composition. The JP 2001 describes kaolin as a native hydrous aluminum silicate.
