Category of Cinnamon Water
Non-medicated Aromatic Water
Synonyms of Cinnamon Water
Aqua Cinnamon, Saigon cassia
Description of Cinnamon Water
clear, colorless, saturated aqueous solution with characteristic odor and taste of cinnamon
Use of Cinnamon Water
Flavoring vehicle
Are clear, aqueous solutions saturated with volatile oils or other aromatic or volatile substances
Aromatic Waters
Aqueous preparation should be free from…
Empyreumatic (smoke-like) and other foreign odor
Aqueous preparation are generally used as…
flavored and perfumed vehicle
The most satisfactory method of preparation but the slowest and most expensive of two methods.
Distillation
Example of distillation
Strong Rose Water
Is the process of repeatedly using the distillate to distill with fresh portions of flowers/ plant materials to minimize loss of water soluble components.
Cohobation
Example of cohobation
Orange/ Rose flowers
Aromatic waters may be prepared by repeatedly shaking 2g or 2 ml (if liquid) of the volatile substance with 1000 ml of purified water. Set aside for 12 hours, filtered through wetted filter paper, and made to volume by adding purified through the filter.
Direct Solution Method
Advantage of Direct Solution Method
more convenient in terms of time and equipment than distillation
Most frequently employed where aromatic waters may be prepared by incorporating the volatile oil with 15 of talc or with a sufficient quantity of purified siliceous earth or purified filter paper. Purified water (1000 ml) is added, and the mixture is agitated for 10 mins. Then water is filtered and its volume if adjusted to 1000 ml by passing purified water through the filter.
Alternate Solution Method
Talc is used in alternate solution method is the…
dispensing agent that increases the surface of volatile substance ensuring more rapid saturation of water and forms an efficient filter bed thus producing a clear solution
How should be the Cinnamon Water be stored and why?
It should be stored in a tight and light resistant container to protect it from light and excessive volatilization
Aromatic waters may be prepared by one of two official processes:
Distillation and Solution
Category of Concentrated Peppermint Water
Medicated Aromatic Water
Synonyms of Concentrated Peppermint Water
Aqua Menthos Piperitas, Brandy water
Description of Concentrated Peppermint Water
clear, saturated solution of peppermint oil in purified water. A colorless aqueous solution with a characteristics odor and taste of peppermint
Use of Concentrated Peppermint Water
Used as carminative and flavored vehicle
Method of preparation of Concentrated Peppermint Water
Alternate Solution Method
Ethyl alcohol and talc in Concentrated Peppermint Water was used to
dissolve peppermint and dispersing agent, respectively
liquid preparation that contain one or several soluble chemical substance dissolve in suitable solvent or mixture of mutual miscible liquid

solvent
prepared by dissolving the solute in a suitable solvent
simple solution
examples of simple solution
NaCl solution, Strong Iodine solution
prepared by reacting two or more solute with each other in a suitable solvent
Chemical reaction
Example of Chemical reaction
Aluminum subacetate solution, Magnesium citrate solution, sulfurated lime solution

maceration
submerging the solute using percolator
percolation
with the aid of gentle heat
digestion
“blanching,” addition of hot water
Infusion
boiling for 15 minutes
decoction
