If you have actual benzoin, use it as opposed to your tincture of benzoin. Unless you know the strength of your benzoin tincture, you could go from there. 1-3% might be a good start. How about 1.5%. eg: 98.5% perfumers' alcohol, 1.5% benzoin.
You can use a solvent like ethanol to separate benzoin from benzil. Benzoin is more soluble in ethanol compared to benzil, allowing for their separation. By manipulating the solubilities of the two compounds, you can dissolve benzoin first and then precipitate benzil out of the solution.
