· Stimulate your Scents with Rose Oil — Sigma-Aldrich, a brand of MilliporeSigma Vanderbilt Co. Inc. has introduced a natural bentonite clay that is recommended as a suspension stabilizer, emulsion optimizer and rheology modifier for topical personal care products. Vanatural (INCI: Bentonite) was specifically created for formulation into natural personal care products and it is water
· Bentonite clay loading may influence the gas separation efficiency of MMMs; therefore, it is pondered as a one influential parameter in this analysis. Figure 9 shows the CO 2 permeance of the synthesized membrane with increasing filler concentration. It is observed that with the addition of bentonite, the permeability exhibited a decreasing trend at 2 bar pressure. This decreasing trend showed
