Moisture Content
We use the Brabonder Semi-Automatic Moisture Tester (manufactured by the Brabender Corporation of Rochelle Park,New Jersey) for routine determina tion of all moisture contents. -
This procedure, involves drying a ten gram sample in a forced-draft oven maintained at 105C. for ap proximately one hour. This instrument has the ad vantage of reading per cent moisture directly.
BON-03150

Moisture can be determined by a simple loss in weight procedure. For example:
Weigh 2-3 grams of sample into a fared weighing dish and phee in an oven maintained at 105C. for one to two hours. Remove the weighing dish from ' the oven and place in a desiccator to cool. Weigh the sample when cool.

Melting Point Determination
The capillary method is used to determine the soften ing point and melting point of metallic soaps.
A melting point capillary tube with one closed end is filled to a height of approximately 5 mm. with sam ple. The material is shaken down info the end of the capillary tube by gentle tapping. The tube is fastened to the bulb end of nn accurate centigrade thermometer by small gum bands. The thermometer, so fixed, is. inserted in a Thiele melting-point tube containing glyc erine or mineral oil. Heat is applied to the Thiele tube so that the temperature.-pf the heating medium, is raised at the rate of 2CC. permin. in the melting range.
The temperature at which the sample shrinks away front the. walls of the capillary lube is recorded as the softening point.. "" '
Thetempeiature at which the sample becomes clear or liquefies is recorded as the melting point.
NOTE: While the techniques and apparatus used in the melting point determination are commonly em ployed throughout industry, metallic soaps present certain difficulties.
Most metallic soap's have fairly broad ranges for softening points and melting points. In addition, some metallic soaps, such as calcium and magnesium stea rates, do not liquefy. Instead, th^y shrink to a sod-like mass and become clear. We define this temperature as the melting point. It is sometimes difficult to observe this phenomenon.
Other devices, such as the Fisher-Johns Melting Point Apparatus, can also be used. We find, however, that the softening point is difficult to determine with this instrument.
Arsenic Deferminalion The procedure for the determination of arsenic in 2-mc
stearate is given in the U.S. Pharmacopeia XVII. To determine arsenic in calcium stearate, use the
same procedure given for the determination of arsenic in magnesium stearate in U.S.P. XVI.
Lead Defermirtafion
The procedure for the determination of lead in mag nesium stearate and zinc stearate is given in the United States Pharmacopeia XVII.
Lead can be determined in calcium stearate using
the same procedure.
Hulk Delerminaf/on
Our laboratories follow the procedure outlined by the Toilet Goods Association Method 12, requiring a specifically constructed dropping box. The stearate is thoroughly Huffed up, 10 grams weighed out and trans ferred to a 250 nd. graduate. The graduate is stop pered and dropped 100 times through a height of 2 inches. The height of stearate in the graduate is read in mis. and calculated to fluid ounces per pound, or to pounds per cubic foot.
Calculations:
fl. 07.s. per lb. --- mis. per gin. X 15.3 lbs. percu. ft. -- 62.4 X g'as. per ml.
It .should be noted that the measure of apparent density, even when following a prescribed method is, to some extent, manipulative. Consequently, it cannot be expected that published figures by all manufactur ers will be comparable on the same basis. When com paring grades, it is well for the prospective user to compare-them himself. '
Our laboratories have constructed a motor driven instrument which conforms to T.G.A. Method No. 12. but which minimizes the possibility of variation in.an operator's technique.
Screen Analysis
A 10 gram sample of stearate is weighed out accu- . rately and transferred to a-400 ml. beaker. Add 3.00 ml.-of "Solox" (U.S.I. proprietary solvent). Carefully- mix the stearate in the alcohol to eliminate all lumps.
The wetted stearate is carefully poured in small por tions onto a' tared 3 inch diameter 325-mesh screen. Wash the screen with "Solox" after each addition of wetted stearate. The screen may be gently tapped with a spatula to decrease the screening time.
Continue until all the wetted stearate has been transferred to the screen.
The residue on the screen may be very gently brushed with a camel's hair brush to break up any agglomerates. The residue is then washed with "Solox" until no stearate passes through the screen.
Place the screen in an oven at 105C. for one hour. Cool the screen and weigh.
