Coalescence stability of emulsions containing globular milk proteins.

This review summarizes a large set of related experimental results about protein adsorption and drop coalescence in emulsions, stabilized by globular milk proteins, beta-lactoglobulin (BLG) or whey protein concentrate (WPC). First, we consider the effect of drop coalescence on the mean drop size, d32, during emulsification. Two regimes of emulsification, surfactant-rich (negligible drop coalesc...

Stability of Nonaqueous Emulsions

We examined the stability of emulsions of oil in several nonaqueous polar liquids using commercially available nonionic surfactants. Stable nonaqueous emulsions were only obtained with formamide and dimethylsulfoxide. Hydrogen bonding, and not polarity, appears to be the important factor determining the emulsifying power of a solvent. Ostwald ripening plays a much more important role in the sta...

Multiple Emulsions – Preparation and Stability

Multiple emulsions (W1/O/W2) with a long-term stability of at least 12 months were prepared in order to encapsulate low molecular weight bioactive substances (Mr < 2000 g/mol). The influence of the emulsifying procedure, i.e. the variation in energy input for dispersing W1/O in W2, and the influence of the emulsion composition were investigated in relation to emulsion stability and encapsulatio...

Pickering emulsions with controllable stability.

We prepare solid-stabilized emulsions using paramagnetic particles at an oil/water interface that can undergo macroscopic phase separation upon application of an external magnetic field. A critical field strength is found for which emulsion droplets begin to translate into the continuous-phase fluid. At higher fields, the emulsions destabilize, leading to a fully phase-separated system. This ef...

Stability and sensory assessment of emulsions containing propolis extract and/or tocopheryl acetate

The prevention of skin aging has been one of the main aims of cosmetic products. Propolis and tocopheryl acetate can be promising substances because of their antioxidant properties. In this study, propolis extract was obtained and associated with tocopheryl acetate in a cream formulation, which then underwent stability and sensory assessment. The formulation containing propolis extract and toco...
