So not all the ingredients that contain the word 'sodium' in their name are the same. Some are salts like 'sodium chloride' or a strong surfactant like 'sodium laureth sulfate' but it can also be a milder surfactant like' Sodium Cocoyl Isethionate' or even 'Sodium PCA' that is a humectant. The bottom line is, you can't draw any conclusion when you see an ingredient that has 'sodium in the name'. And even if sometimes the name of 2 ingredients is almost exactly the same, their effect and risks can be completely different. That's why we provide the blacklist ingredient and scanner to help you navigate the chemistry of your products without having to pull your hair out wondering about each individual ingredient. Regarding "Sodium Myristoyl" it's likely not the full name of the ingredient. It would be either Sodium Myristoyl Glutamate or Sodium Myristoyl Sarcosinate. These ingredients are not blacklisted.
