DSM Personal Care presented new research findings on robust emulsification at the Sunscreen Symposium in September.
The presentation highlighted DSM’s Amphisol K, an oil-in-water emulsifier capable of delivering outstanding sunscreen stability combined with ease of product development. Using comparative science the presentation showed formulators how to overcome current challenges posed by high UV filter and pigment loads over a broad viscosity range. It also illustrated the potential for development of a new generation of highly sophisticated sunscreens and day care products which combine a high level of protection, while delivering sensorial attributes that promote consumer compliance.
Research has shown that Amphisol K provides stability through its ability to form mainly lamellar structures of very densely packed layers of water and liquid crystalline lipid phases. Hitherto the micro-domains thought to be responsible for stabilising emulsions have rarely been seen, but freezefracture Scanning-Electron-Microscopy has recently enabled DSM to identify these micro-domains.
