» Prepare Mineral Oil Emulsion as follows:

Mix the Mineral Oil with the Powdered Acacia in a dry mortar, add 250 mL of Purified Water all at once, and emulsify the mixture. Then add, in divided portions, triturating after each addition, a mixture of the Syrup, 50 mL of Purified Water, and the Vanillin dissolved in the alcohol. Finally add Purified Water to make the product measure 1000 mL, and mix.

The Vanillin may be replaced by not more than 1 percent of any other official flavoring substance or any mixture of official flavoring substances. Sixty mL of sweet orange peel tincture or 2 g of benzoic acid may be used as a preservative in place of the Alcohol.

For other permissible modifications, see Emulsions 1151.
