10 Questions
What information does the melting range of fatty suppository bases provide?
The temperature at which the fat is completely melted
Why do fatty suppository bases not have sharp melting points?
Due to the presence of triglycerides
What does the solid-fat index (SFI) help determine in fatty bases?
Molding character and surface feel
Why might manufacturers of fatty bases use different methods for determining melting characteristics?
To align with international standards
What does the hydroxyl value measure?
The measure of unesterified positions on glyceride molecules
What does the saponification value indicate?
The milligrams of potassium hydroxide required to neutralize the free acids and saponify the esters in 1 g of fat
What does the solidification point value allow prediction of?
Time required for solidifying a molded base
What does the solidification point value indicate when there is a reduced differential between mold temperature and mass temperature?
Brittle base if molded too quickly
What does the solid-fat index (SFI) measure?
The rate of solidification of a fatty base
What does the saponification value represent in terms of chemical content?
Ester content
