Multiple emulsions are emulsions where the disperse phase is itself an emulsion containing drops of another phase. Even quintuple emulsions were studied by Zeifritz, where snapshots of the drops are presented. Most common are double emulsions, where the disperse phase contains drops of the dispersion medium Multiple Emulsionen können u.a. zur Flüssigmembran-Permeation genutzt werden, bei der die mittlere Phase (Membranphase) als Filter zwischen innerer und äußerer Phase dient Multiple emulsions are complex polydispersed systems where both oil in water and water in oil emulsion exists simultaneously which are stabilized by lipophillic and hydrophilic surfactants respectively.

Nonspherical colloidosomes with multiple compartments are generated using water‐in‐oil‐in‐water double emulsions with controlled morphology as templates (see image). Double emulsions are prepared using a glass capillary microfluidic device that provides a precise means to control the number of internal aqueous droplets and the volume ratio of oil and aqueous phases Multiple emulsion stability also correlated with the interfacial film strength (measured by interfacial elasticity) of the hydrophobic surfactant at the mineral oil/external continuous aqueous phase interface. The formation of the metastable dimpled structures and the long-term stability of the multiple emulsions were dependent on the osmotic pressure of the inner droplets and the Laplace.

Multiple emulsions (W 1/O/W 2) with a long-term stability of at least 12 months were prepared in order to encapsulate low molecular weight bioactive substances (M r < 2000 g/mol). The influence of the emulsifying procedure, i.e. the variation in energy input for dispersing W 1/O in W 2, and the influence of the emulsion compositi on were investigated in relation to emul-sion stability and. The preparation of emulsions requires energy to disperse the organic phase (solvent or solution) in water. In order to get an idea about the thermodynamics the change in the Gibbs free energy of the system (∆G), provided by the particular dispersing procedure at constant composition and pressure, can be expressed by: ∆G =∆H−T⋅∆S The entropy (∆S) is a measure of the extent of.

Multiple emulsions are also known as emulsions of emulsions, liquid membrane system or double emulsion. These have been proposed to have numerous uses including their use for enhancement of bioavailability or as a prolonged drug delivery system. Multiple emulsions are often stabilized using a combination of hydrophilic and hydrophobic surfactants An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid (the dispersed.

Multiple emulsions spontaneously form when there is a conflict between the formulation and composition effects. In such systems the most external emulsion is found to be unstable when the formulation effect is produced by a single surfactant. The use of a proper surfactant−polymer mixture allows one to strongly inhibit the mass transfer and to considerably lengthen the equilibration between. Further, they can form multiple emulsions, such as water in oil in water. Most emulsions are unstable, with components that won't mix on their own or remain suspended indefinitely. Emulsifier Definition . A substance that stabilizes an emulsion is called an emulsifier or emulgent. Emulsifiers work by increasing the kinetic stability of a mixture. Surfactants or surface active agents are one.
