Acacia, in very fine powder 125 g

Alcohol 60 mL
Purified Water, a sufficient quantity to make 1000 mL
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.
