Abstract:

An open-pored mesoporous silica (OSMS) was successfully prepared by emulsion method. Its microstructure was analyzed using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and nitrogen adsorption-desorption tests (BET). The results showed that, the OSMS particles were monodisperse, and the particle size was 0.40 μm; the product had open channel structure and uniform mesopore size distribution (pore diameter of 24.4 nm); OSMS had high specific surface area (162 m2/g) and large pore volume (1.12 cm3/g). The results of performance study indicated that, in the oil absorption value test for 10 different oils and fats, OSMS demonstrated superior adsorption performance. Its oil absorption values were 1.3-1.9 times that of porous silica 150H, 3.3-6.3 times that of silicone elastomer KSP-100, and 6.0-7.5 times that of the starch-based TAPIOCA, respectively. Human skin oil-control experiments indicated that OSMS had the features of rapid and long-lasting adsorption, and the oil-control effect was linearly and positively correlated with the dosage (R2>0.95). In vitro SPF value tests showed that OSMS had sun-screening synergistic effect, and just 0.3% (w/%) OSMS could increase the SPF value of a sunscreen. This work might provide experimental support for the application of OSMS as an oil-control raw material and a sun-screening synergist in cosmetics.

Key words: emulsion method, open pore structure, mesoporous silica, adsorption performance, synergistic sun-protection effect
