BergaMuls ET 1 is a multifunctional active ingredient based on swellable, soluble, and insoluble natural cereal and fruit fibers. BergaMuls ET 1 thus combines the properties of classic O/W emulsifiers with those of vegetable thickeners - it emulsifies and thickens in a single step. O/W emulsions based on BergaMuls ET 1 are convincing because of their stability, skin compatibility, and lightness and are particularly distinguished by their high electrolyte tolerance and high pH tolerance. BergaMuls ET 1 tolerates all oils - from ester oils (such as Dermofeel Sensolv) to natural vegetable oils and non-polar oils (such as Cetiol Ultimate, squalane). A particular advantage of this emulsifier is that it can be processed both cold and warm. 
 
Application concentration: 
1,5 - 5,0 % 
 
pH range: 
4 - 9 
 
Fields of application: 
Face and body care, sun protection products, decorative cosmetics, and hair care. 
 
Processing: 
In principle, BergaMuls ET 1 can be dissolved in the water phase as well as dispersed in the fat phase. However, the latter is recommended. 
 
Disperse BergaMuls ET 1 in the fat phase and then heat the fat phase to 70 - 80 °C. The water phase should also be heated to 70 - 80 °C. 
Heat the water phase to 70 - 80 °C as well. 
Add the water phase to the fat phase and homogenize at high speed for 1 - 4 min. 
Allow to cool to hand-warm. Continue to stir moderately while cooling. 
Stir the temperature-sensitive ingredients into the hand-warm emulsion, then homogenize at high speed for approx. 1 min.
Preserve and adjust the pH value if necessary. 
After approx. 24 h, stir again at high speed for approx. 1 min.
