Abstract: A method for preparation of a semitransparent colloidal solution of bismuth sodium tartrate generally comprises producing an aqueous solution of bismuth sodium tartrate; extracting a magma of bismuth sodium tartrate from the aqueous solution at a pH of approximately 2.2; and then dissolving the magma into a salting-in mixture. After addition of preservative and strength testing, the base solution is diluted to elixir strength. The elixir is then buffered to a pH range of about 7.2 to about 7.3 in order to maintain for an extended duration the semitransparent nature of the elixir.

Abstract: A method for preparation of a semitransparent colloidal solution of bismuth sodium tartrate generally comprises producing an aqueous solution of bismuth sodium tartrate; extracting a magma of bismuth sodium tartrate from the aqueous solution at a pH of approximately 2.2; and then dissolving the magma into a salting-in mixture. It is critical that the magma be extracted at a pH of at least 2.2 but not more than 2.3. As a result, the magma is extracted by washing with a wash liquor comprising an addition of distilled water; allowing the magma to settle out of the wash liquor; measuring the pH of the wash liquor after the magma has settled; and then decanting the wash liquor from the magma. This process is then repeated as necessary to arrive at a magma within the critical pH range, whereafter the magma is air dried in preparation for salting-in. After addition of preservative and strength testing, the base solution is diluted to an elixir strength.
