Natura - Tec Emulactive W - Oil in Water

Natura-Tec Emulactive W - Oil in Water
INCI :
Cetearyl Alcohol (and) Glyceryl Stearate (and) Potassium Palmitoyl Hydrolyzed Wheat Protein
Characteristics:



Pellets
Soluble in oil phase
Forms lamellar liquid crystal system
PEG free
Fluid viscosity emulsion (can be adjusted with thickeners)
Light skin feel, highly spreadable
Process in Formulation/ Hot Process :
Prepare aqueous and oil phases at room temperature.
Add Natura-Tec Emul-active W to the oil phase at room temperature.
Heat the oil phase up to 60 °C (be careful not to overheat the emulsifier due to the presence of hydrolyzed Wheat
protein).
Heat at the same time the water phase up to 70°C.
At temperature, add the oil phase to water phase under high speed agitation and then shear with a rotor stator
system (Ultra turrax, Silverson, etc).
Operating with “reverse phase” (oil phase added to water phase during the process) can also be done.
Cool at room temperature under slow agitation.
Add the sensitive phase (actives, perfume, preservatives etc) below 40°C.
Adjust pH.
Main parameters controlling stable emulsifying performance






% of the emulsifier – from 4 % to 10 %
Composition of the oil phase : excellent affinity with vegetable emollients (vegetable oils, etc)
% of the oil phase : 5% to 30%
At low percentage of use an addition of a rheological modifier is recommended (Xanthan Gum ,
Sclerotium Gum, etc) to improve stability.
Consistent emulsions can be achieve by using a thickener (Cetearyl Alcohol, Stearic Acid, Beeswax, etc)
Optimal pH range of the final emulsion: 5,5 - 8,0
Sensorial Profile
Emulsions obtained with Natura-Tec Emul-Active W present very special sensorial benefits:

Light and smooth texture

Highly spreadable

Medium absorption

Smooth and pleasant after feel
