The physical characteristics of the O/W
microemulsion made from the surfactant
cetyltrimethylammonium bromide (CTAB), cold liver oil,
water, and lauryl alcohol (LA) as a non-ionic
cosurfactant were investigated using Electrical
conductivity and hydrodynamic viscosities at various
temperature and different oil additions. The range of
concentration CTAB ranged from 1× 10-3 M to 2 × 10-2 M.
Through the aid of the level of the critical micelle
concentration (CMC) and the typical free energy of
m) dissociation () micellization was assessed.
Also discovered is that the growth of the CMC of CTAB
is gradually accompanied by a starting at 25 °C to 55 °C.
It is obvious to see that the CMC of CTAB continues to
rise when more cold is introduced. increased by liver oil.
In light of the findings from this study, it can the usage of
CTAB is advised for micellization in watery medium and
the creation of optical or water emulsions or
microemulsions would have many applications in the
future, especially in the production of pharmaceuticals
