SODIUM METHYLNAPHTHALENESULFONATE

Safety grade: A

This is a chemical compound made in the laboratory that helps cosmetic products achieve a gel-like texture and keeps all the ingredients mixed together smoothly. It works similar to soap in helping oils and water blend.

It thickens products into gels, helps dissolve ingredients that normally don't mix well together, and acts as a gentle cleanser to improve product texture and stability.
