Comparison of a num- ber of market emulsifiers using the same technology showed the analysed emulsifier brand to have a phosphate content that was anything from 3 to 84 times lower than the comparisons. The study demonstrated that with the emulsifier, ethanol concentrations between 0% and 15% can be stabilised and that it outperformed similar market tech- nologies for pigment compatibility. The test results also revealed that market products using potassium cetyl phosphate technol- ogies with the highest levels of phosphate showed phase separation after a few weeks, whereas others with medium to high phos- phate levels showed a dramatic increase in viscosity over time. In contrast, with the tested emulsifier, tests with pigment con- centrations up to 10% showed that viscos- ity remained stable over the 3-month test period compared to competition. Using cut- ting-edge technology known as freeze-frac- ture Transmission Electron Microscopy, DSM has for the first time visualised that the emulsifier uniquely forms the rarely seen micro-domains in emulsions, which are sup- posed to stabilise the so-called liquid crys- talline vesicular structures. www.dsm.com BIO-SURFACTANTS EVONIK | After five years of research, Evonik now uses bio- tech methods for producing industrial-scale quantities of sur- factants. These products contain sophorolipids, which are produced in nature by a yeast and which can be found in the honey produced by bumblebees, among other sources. The company also plans to develop and market rhamnolipids with exceptional foam-forming properties as another class of biosurfactants. For the production of rhamnolipids through fermentation bacteria will be used instead of yeasts. Up to now, surfactants have been produced almost exclusively through synthetic processes. www.evonik.com Bio-­ surfactants can to be produced without petroleum or tropical oils INGREDIENTS NEWS www.cossma.com  l  39 a.com RHEOLOGY MODIFIER COATEX | Rheostyl 85 L dedicated to natu- rally preserved cleansing products is a rheology modifier which allows the claim “free of” all types of synthetic preservatives.
