The range can serve as emulsifiers (o/w, w/o and co-emulsifiers), co-surfactants (non-ionic), solubilizers and rheology modifiers. They are both water and oil soluble in addition to being cold processable. In addition to being naturally derived, the line is PEG-free and non-nitrosamine forming. According to the company, the polyglycerol esters can enhance skin texture and contains ingredients that are known to be beneficial to cosmetic formulations.
