it's our aim to provide notes for pharmacy student without any charge.so that we make pharmacy education easier. किसी भी शुल्क के बिना फार्मेसी छात्र के लिए नोट्स प्रदान करना हमारा लक्ष्य है।ताकि हम फार्मेसी शिक्षा को आसान बना दें।

1. Emulsion
# Coarse dispersion.
# One phase dispersed as a glubules
in another phase.
#Thermodynamically unstable.

2. Types of Emulsion
01、o/w
Oli dispersed
phase water
continuous
phase .
02、w/o
Water dispersed
phase oil
continusoues
phase .
03、Multiple
emulsion
04、Micro
Emulsion

3. Multiple Emulsion
# It is a complex system
# Simple emulsion dispersed in other
liquid medium .
O/w/o
W/o/w

4. Micro Emuslion
#Simple emulsion-:
Partial size of d.p. 0.1
micrometer to 100
micrometer .
*Multiple emulsion
partial size of d.p. less
than 0.1 micrometer.

5. Dye test
Fluroscence test
Conductivity test
Dilution test
Test for identification of
emulsion

6. Dilution test
Emulsion
Water
Break -: w/o
Stable -: o/w

7. Emulsion
Bulb Not Glow
Electrode W/o
Conductivity
Test

8. Emuslion
Bulb
Electrode O/w
Glow

9. Fluroscence test
Emulsion
Exposure to uv lights
W/o O/w
# Emulsion on exposure to ultra
boiler radiation show continuous
florescence W/o
* Emulsion on exposure to uv
radiation show spotty
florescence under microscope
O/w

10. Dye test
W/o O/w
#Scarlet red dye is
mixed with emulsion
place a drop of
emulsion on slide and
examine under
microscope .

11. #If the dispersed
globule appear red and
background is
colourless it is o/w
emulsion.
# If background appear
red in colure and
globules colourless it is
w/o emulsion.
