Sodium ethyl xanthate Sodium ethyl xanthate Sodium ethyl xanthate (SEX) is an organosulfur compound with the chemical formula CHCHOCSNa. It is a pale yellow powder, which is usually obtained as the dihydrate. Sodium ethyl xanthate is used in the mining industry as a flotation agent. A closely related potassium ethyl xanthate (KEX) is obtained as the anhydrous salt. As with most xanthates, sodium ethyl xanthate can be prepared by treating sodium ethoxide with carbon disulfide: Sodium ethyl xanthate is a pale yellow powder. It is relatively stable in water at high pH if not heated. It rapidly hydrolyses at pH <9 at 25
Ethyl macadamiate similar to that of some silicone derivatives, however, Ethyl Macadamiate is non-volatile. Ethyl macadamiate is used in cosmetics, especially in skincare, haircare and suncare formulation. The dry skinfeel and high spread make ethyl macadamiate well suited for increasing sunscreen coverage. Ethyl macadamiate is an alternative to cyclomethicone and dimethicone as a skinfeel modifier where a botanical, nonvolatile and/or lipid-soluble substance is preferred.
