影片是說 這成份仍含有50%SLS 還是會刺激皮膚
In summary: sodium coco sulfate contains SLS as a predominant component, with all the concerns that are linked to that chemical. Basically it is just another way to hide SLS in formulations with yet another name. Both sodium coco sulfate and SLS are synthetic detergents and should never be part of any natural cleanser. Natural products that are kind to your skin, and environmentally friendly, will not contain lauryl sulfate, laureth sulfate, coco sulfate or any of the long list of other synthetic detergents.
