Hydrophilic

The hydrophilic-lipophilic balance of a surfactant is a measure of the degree to which it is hydrophilic or lipophilic determined by calculating values for the different regions of the molecule as described by Griffin in 1949 and 1954 Other methods have been suggested notably in 1957 by Davies Griffin's method Griffin's method for non-ionic surfactants as described in 1954 works as follows:

Results and Discussion of the Characteristics of Emulsion

06 11 2015We obtain this result based on which HLB value resulted in the longest time for phase separation to reach 1 cm From the result mostly the HLB for stable emulsions are less than 10 So the resultant surfactant characteristic is lipophilic The emulsions from tube 7 and tube 8 have the lowest stability as we can see the phase separation took the shortest time This is because the absence of

US Patent for Medicament with a delayed release of active

In addition to the active ingredient the capsules contain a nonionic surfactant consisting of a polyglycol ester or ether having hydrophilic and lipophilic portions and an organic polymer which is capable of forming a free-flowing composition with the active ingredient and the surfactant The essential point for the delay in release is the matching of the water-solubility of the active

Emulsions and the HLB System

Emulsions and the HLB System All creams and lotions have one thing in common They are both emulsions An emulsion is a system of two (or more) immiscible materials (usually liquids) in which one material (the dispersed/internal phase) is suspended or dispersed throughout another material (the continuous/external phase) in separate droplets Most emulsions fall into two different classes oil
