Sodium coco sulfate (SCS) –This is a relatively ‘new’ sulfate that has surfaced on labels as companies try to get away from SLS and SLES in their ingredient lists or try to claim a milder sulfate. Sodium Coco Sulfate guarantees the fatty alcohol was extracted from coconut (rather than petroleum or palm oil). However, all lauric fatty acids have always been derived from one of these three oil origins, so really this name specifies which oil source the end sulfate was originated from. Whatever kind of oil it starts with, the process to make any of the sulfates is –through a number of chemical processes- to extract lauric fatty acid, transform it into lauric fatty alcohol, which is then treated with sulfuric acid (makes sulfate), then finally neutralize to produce the specific form sodium salt. SCS ends up with the same chemical number as SLS, and the same statement on it’s Material Safety Data Sheet; it’s a skin and membrane irritant. AKAs for Sodium coco sulfate - monococoyl ester sodium salt sulfuric acid; sodium salt sulfuric acid, monococoyl ester; sulfuric acid, monococo alkyl esters, sodium salts; sulfuric acid, monococoyl ester, sodium salt.
Other sulfate names –Sodium caprylic sulfate, Sodium capric sulfate, Sodium oleic sulfate, Sodium stearyl sulfate, Sodium myreth sulfate, Sodium dodecanesulfate, Sodium monododecyl sulfate., etc
