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
