Name other examples of aromatic waters:

Strong Rose Water, USP Orange flower water Camphor water 3.

Determine the amount of ingredients needed to prepare 10 mL of Peppermint Water, NF:

Talc: (2 mL/ 1000 mL) (x g/ 10 mL)= 0.02 g Peppermint oil: (15 g/ 1000 mL) (x g/ 10 mL)= 0.15 g

4.

Give the use of each ingredient in the preparation:

Talc- breaks volatile substances into minute particles thereby exposed to solvent; it removes excess of the volatile substance and is insoluble in water, therefore easy to remove. It is also a dispersing agent. Peppermint oil- the gives flavor and taste Substitutes for talc- kielseghur, siliceous earth (clay), charcoal, chalk, magnesium carbonate

5.

What are the two methods of preparing aromatic waters:

Distillation- is the most ideal way for efficiency and quality of yield. It is slow and decomposition of essential oils and it may volatilize due to heat. Solution- more convenient in terms of time and equipment but the excess oils may be drawn off  by water.

6.

Quality control parameters:
