Polyglycerol esters are much milder than anionic surfactants and can be used for the preparation of ethoxylate-free emulsions.
An important attribute of polyglycerol esters is the possibility of producing tailor-made emulsifiers with the desired hydrophile/lipophile balance (HLB) through the appropriate selection of the type of fatty acid and polyglycerol, their ratio, and manufacturing conditions.
Depending upon their HLB, polyglycerol esters can act as water-in-oil (W/O) or oil-in-water (O/W) emulsifiers, or O/W co-emulsifiers.
In several systems, polyglycerol esters have a better surface activity than glycerol (5,6) or homologous polyol esters.
The performance of polyglycerol esters in stabilizing emulsions is strongly dependent on their ability to form lamellar liquid-crystalline phases in water (Fig.
The similarity between these lamellar crystalline phases and the self-organized structures of the natural stratum corneum lipids (7) explains why polyglycerol esters have very good skin fat replenishing properties.
Polyglycerol esters stabilize O/W formulations by decreasing the interfacial tension between the oil and the aqueous phase, and by increasing the viscosity of the external phase, thanks to the formation of a gel network.
