How do I make a suspension with: precipitated sulfur 6 g, zinc oxide and talc AA 15 g, menthol 0.5%, glycerin 15 g, alcohol and water AA AD 100 ml.

Bring in a small mortar 0.5 g hydroxypropylcellulose and mix   with the other powders (except menthol) and then rub with glycerin. Pour the contents into a bell-shaped measuring glass and determine the volume. Calculate the remaining volume and divide it into equal parts over alcohol and water. Add the water to the contents of the size glass.   Dissolve Methhol in the alcohol and mix this solution with the mixture in the size glass.
