Correlation of fumed silica
1, fumed silica and nail polish
Among the nail varnishes, AEROSIL fumed silica ensures uniform distribution of the pigment in the brightener, prevents pigmentation, and provides rheology of the final product to improve coatability. If the refractive index of the solvent system used is the same as that of AEROSIL fumed silica (1.48), transparent nail polish formulations such as base color and face color can be formed. Otherwise, when the concentration is higher, it has a matting effect, which in turn reduces the desired gloss. Both hydrophilic and hydrophobic AEROSIL fumed silica products can be used in nail polish. It is recommended that AEROSIL be used at concentrations between 0.25 and 4.0%.
2, fumed silica and lipstick
In the lipstick, AEROSIL fumed silica can evenly distribute the pigment, and can greatly improve the temperature resistance and prevent the softening of the lipstick when the temperature rises. After applying the lips, AEROSIL can prevent the lipstick from transferring to the small lip lines. In the middle, there is bleeding, so that the lipstick does not decolorize for a long time. When the concentration is higher, the gloss will decrease.
AEROSIL 200 or AEROSIL R972 can be used at a concentration of 0.25-4% depending on the desired product characteristics. Up to 10% of AEROSIL R972 can be used in certain special formulations, such as foundations or lip balms.
3, fumed silica and eye care
Many eye and face make-up products, including powder, foundation, rouge, mascara and eyeliner, use only AEROISL fumed silica to achieve the desired characteristics and the necessary stability. AEROSIL fumed silica is a highly effective anti-caking agent and free-flowing agent that improves storage stability and dispersion of powdered products. AEROSIL also enables the use of pigments in cosmetics, especially in the case of high solids content. Finally, AEROSIL can be used as an efficient processing aid for grinding and filtering powders.
