Guest guest Posted October 5, 2003 Report Share Posted October 5, 2003 Hi, does someone know the use of magnesium sulphate in cosmetic formulations. I've read that it was used to stabilize and I've also read that it is used to thicken. RJ Quote Link to comment Share on other sites More sharing options...

Here are a few formulations that use MgSO4 for seemingly others uses. ------------------- From USPAT#6514485 The cosmetic compositions of the invention can also comprise other conventional components, for example emulsion stabilizers such as sodium chloride or citrate, magnesium sulfate and analogs, in amounts ranging from about 0.1 to about 5% of the composition weight; ___________________ From USPAT#6267975 Example 9 Prepare liquid cleansing component.

Guest guest Posted October 6, 2003 Report Share Posted October 6, 2003 Can't think why its used in the cleansing product, but mangnesium sulfate is used to stabilise water in oil emulsions, as you will see in many W/O formulations. I was once told this by a Croda rep, who couldn't offer an explanation as to the stabilising mechanism.
