3. INTRODUCTION
An eutectic mixture is a mixture of several components is a
particular ratio, which melts sharply below the melting point of
any individual component..
Eutectic Mixture:
Eg-Menthol, Thymol.

4. Melts below
the melting
point of
individual
component
During
formation, the
components
are miscible in
liquid state
but
immiscible in
solid state
The
melting
point is
always
fixed

5. PRINCIPLES OF EUTECTIC MIXTURE
Be
of the two mixture of the two substances will
exist as a solid..
While above it the mixture will convert into a
liquid.

6. C

7. FACTORS AFFECTING THE FORMATION
OF EUTECTIC MIXTURE
Th
imbalance to the mixture and throw all the solidification point.
It is necessary to adjust the ratio of the components in the mixture.
It is also necessary to closely control the components of
impurities

8. Uses
It becomes necessary to identify the formation of eutectic mixture
between components of formulation to avoid the problems of
manufacturing.
It is commonly used in drug designing and delivery processes for
various routes of administration

9. Example
Some eutectic mixture are :
Curcumin
-Nicotinamide(1:2)
Ibuprofen –Thymol (2:3)
Borneol –Menthol(1:9)
