Sodium Coco Sulphate vs. Sodium LaurylSulphate 

I have already posted on sulphates once (previous post) so I won’t go into crazy detail about how sulphates aren’t dangerous.  Yes, that’s right.  Despite the bad reputation they are nothing scarier than an irritant and an allergen.  So, if you aren’t bothered by the harsh stripping qualities of sodium lauryl sulphate, don’t you worry and keep on truckin’!  For those of you looking for a ‘cleaner’ alternative, don’t go looking for sodium coco sulphate.  It ain’t much better.Sodium coco sulphate is exactly the same chemical compound as sodium lauryl sulphate the only difference is the way that the coco sulphate is derived from coconuts.  Before you get up on your high green horse and feel like this is better, think about this: not only are both sulphates coconut derived, they both have exactly the same CAS number 151-12-3.  CAS numbers are unique identifiers given to chemicals by the Chemical Abstracts Service.  Same number means it’s the same chemical.  Sodium coco sulphate is really just a diluted, less pure version of sodium lauryl sulphate.  This means that it won’t lather quite as well, or perform as consistently as the lauryl sulphate.  

What it comes down to? Sodium lauryl sulphate and sodium coco sulphate are just like hard and soft water but they’re both “water”.  If you react to sodium lauryl sulphate you will react to sodium coco sulphate.  Sure, coco sulphate is more dilute, but if you really want to go for something ‘cleaner’ without this stripping agent, keep searching.  And remember: lots of lather doesn’t mean extra clean.
