This Face Cream with AEROSIL® R 974 is a water-in-oil Pickering emulsion.
The formulation features AEROSIL® R 974 which is a moderately hydrophobic treated fumed silica that is efficient in the thickening and thixotropy of low and non-polar emollients. This ingredient is commonly used in w/o Pickering emulsions and also aids in the anti-settling of particles in liquid formulations.
TEGOSOFT® Liquid is a medium-viscosity cosmetic ester, similar to natural preen gland fat. This ingredient acts as an emollient with good spreading properties and low occlusivity.
