>Does anyone know where I can purchase magnesium stearate and sericite?

The INCI name for Sericite is Mica. Does that help?

Would it be safe to " assume " that it is a white or off-white mica,

or is it a specific mica?

I think we're talking about the same stuff.

21 CFR 73.1496 Mica.

(a) Identity. (1) The color additive mica is a white powder obtained from the

naturally occurring mineral, muscovite mica, consisting predominantly of a

potassium aluminum

silicate, K2Al4(Al2Si6O20)(OH)4 or, alternatively, H2KAl3 (SiO4)3. Mica may be

identified and semiquantitatively determined by its characteristic X-ray

diffraction pattern and

by its optical properties.

(2) Color additive mixtures for drug use made with mica may contain only those

diluents listed in this subpart as safe and suitable for use in color additive

mixtures for

coloring drugs.

( Specifications. Mica shall conform to the following specifications and shall

be free from impurities other than those named to the extent that such other

impurities may be

avoided by good manufacturing practice:

Fineness, 100 percent shall pass through a 100-mesh sieve.

Loss on ignition at 600-650 deg.C, not more than 2 percent.

Lead (as Pb), not more than 20 parts per million.

Arsenic (as As), not more than 3 parts per million.

Mercury (as Hg), not more than 1 part per million.

Mica is a series of silicate minerals of varying chemical composition but with

similar physical properties. Mica has well-defined cleavage, and splits into

very thin sheets.
