[Ester Composition and HLB ( Sucrose Stearate )]
[The functional properties of SURFHOPE SE PHARMA]
<Hydration>
<Fat crystal control>
The affinity of SURFHOPE SE PHARMA for the water
phase in an emulsion is derived from the hydroxyl groups (A) of the sucrose part
of the molecule. Consequently SURFHOPE SE PHARMA yield emulsions which are exceptionally
heat stable because the hydration of hydroxy groups is far stronger than the hydration
of ether groups(B) in ethoxylated emulsifiers. SURFHOPE SE PHARMA can be used
for heat stabilization and produce emulsions that are more heat stable than competing
products,especially at higher temperatures.
Low HLB SURFHOPE SE PHARMA can modify the crystalline
structure of solid triglycerides with useful benefits to the physical properties
of the product.
<Oil in water emulsion>
<Tablet manufacturing>
SURFHOPE SE PHARMA, with medium-high hydrophilic-lipophilic
balance(HLB), tend to form liquid crystal structures in aqueous solutions.
Because of their compact structure, SURFHOPE SE PHARMA coats the interfaces of
emulsions very efficiently.
Low-medium HLB SURFHOPE SE PHARMA are not alkaline
and are practically taste-free, a great advantage over magnesium stearate.
