Light Kaolin (Natural) BP
Action and use: Antidiarrhoeal.
DEFINITION
Light Kaolin (Natural) is a native hydrated aluminium silicate, freed from most of its impurities by elutriation and dried. It does not contain a dispersing agent.
CHARACTERISTICS
A light, white powder free from gritty particles; odourless or almost odourless; unctuous. Practically insoluble in water and in mineral acids.
IDENTIFICATION
A. To 0.5 g in a metal crucible add 1 g of potassium nitrate and 3 g of sodium carbonate and heat until the mixture melts. Allow to cool. To the residue add 20 ml of boiling water, mix and filter. Wash the residue with 50 ml of water, add to the residue 1 ml of hydrochloric acid and 5 ml of water, mix and filter. To the filtrate add 1 ml of strong sodium hydroxide solution, filter and add to the filtrate 3 ml of ammonium chloride solution. A gelatinous white precipitate is produced.
B. 0.25 g yields the reaction characteristic of silicates.
C. Triturate 2 g with 2 ml of water. The resulting mixture does not flow.
TESTS
Coarse particles; Arsenic; Heavy metals; Chloride; Loss on drying; Loss on ignition; Soluble matter: Complies with the requirements stated under Light Kaolin.
Fine particles: Disperse 5 g in 250 ml of water containing 50 mg of sodium pyrophosphate by shaking vigorously for 2 minutes in a stoppered flask, pour immediately into a glass cylinder 5 cm in diameter and transfer 20 ml to a glass dish using a pipette. Evaporate to dryness and dry to constant weight at 105C. Allow the remainder of the suspension to stand for 4 hours at 20C and withdraw a second 20 ml portion using a pipette with its tip exactly 5 cm below the surface and without disturbing the sediment. Transfer the second portion to a glass dish, evaporate to dryness and dry to constant weight at 105C. The weight of the residue from the second portion is not less than 70% of the weight of the residue from the first portion.
Light Kaolin BP
Action and use: Antidiarrhoeal.
DEFINITION
Light Kaolin is a native hydrated aluminium silicate, freed from most of its impurities by elutriation and dried. It contains a suitable dispersing agent.
CHARACTERISTICS
A light, white powder free from gritty particles; odourless or almost odourless; unctuous. Practically insoluble in water and in mineral acids.

B. 0.25 g yields the reaction characteristic of silicates.
C. Triturate 2 g with 2 ml of water. The resulting mixture flows.
TESTS
Coarse particles: Transfer 5 g to a stoppered cylinder (about 16 cm × 35 mm), add 60 ml of a 1% w/v solution of sodium pyrophosphate, shake thoroughly and allow to stand for 5 minutes. Using a pipette, withdraw 50 ml from a point about 5 cm below the surface of the liquid. To the remaining liquid add 50 ml of water, shake, allow to stand for 5 minutes and withdraw 50 ml in the same manner as before. Repeat the operation until a total of 400 ml of suspension has been withdrawn under the prescribed conditions. Transfer the remainder to an evaporating dish and evaporate to dryness on a water bath. The residue, after drying at 105C, weighs not more than 25 mg.

The weight of the residue from the second portion is not less than 70% of the weight of the residue from the first portion.
Arsenic: 0.50 g dispersed in 25 ml of water complies with the limit test for arsenic, (2 ppm).
Heavy metals: To pass the test
Chloride: Boil 1.0 g with 80 ml of water and 20 ml of 2M nitric acid under a reflux condenser for 5 minutes, cool and filter. 15 ml of the filtrate complies with the limit test for chlorides, (330 ppm).
Loss on drying: When dried to constant weight at 105C, loses not more than 1.5% of its weight. Use 1 g.
Loss on ignition: When ignited at 600C, loses not more than 15.0% of its weight. Use 1 g.
Soluble matter: Boil 2 g with 100 ml of 0.2M hydrochloric acid under a reflux condenser for 5 minutes, cool, filter and evaporate 50 ml of the filtrate to dryness. The residue, after ignition at about 600C for 30 minutes, weighs not more than 10 mg.
