Emulsion
Emulsion — A mixture of two immiscible liquids where one is dispersed as droplets in the other, used in peptide delivery systems for sustained release applications.
What Is an Emulsion?
An emulsion is a mixture of two immiscible liquids (oil and water) stabilized by surfactants. In peptide formulation, emulsions serve as vaccine adjuvants (MF59, Freund's), oral delivery vehicles (self-emulsifying systems), and peptide encapsulation platforms.
Types
- O/W: Oil-in-water. Aqueous continuous phase. MF59 vaccine adjuvant
- W/O: Water-in-oil. Freund's adjuvant. Longer antigen retention at injection site
- W/O/W: Double emulsion for PLGA microsphere peptide encapsulation
- SEDDS: Self-emulsifying drug delivery systems for oral peptide absorption
