Solubility of colloidal silicon dioxide
WebParteck ® SLC excipient is an innovative silica drug carrier that enhances drug solubility thanks to its unique surface structure, which can stabilize the amorphous state. This is especially relevant for poor glass forming APIs, which can be difficult to stabilize with other formulation technologies. Parteck ® SLC is also emerging as a first-in-class excipient to … WebFeb 24, 2024 · It is derived from the fatty alcohol, stearyl alcohol by ethoxylating it and thus making the molecule a little water-soluble. This version has only a small amount of ethoxylation and thus the molecule is still largely oil soluble. It is often mixed with more water-soluble emulsifiers (such as Steareth-20) to create stable emulsion systems.
