Red Lake 40
Synthetic
Red Lake 40 is a stable salt. This is a synthetic ingredient we use but this ingredient has undergone safety testing in both the US and European Union (EU). In fact both the FDA and EU have approved Red Lake 40 for use in personal care and cosmetic items.
Why do we use Red Lake 40 in Grandma's Approved bath bombs. This ingredient has one job and that is to make things red.
