Blue 1 Lake
Synthetic
Blue 1 Lake 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 Blue 1 Lake for use in personal care and cosmetic items.
Why do we use Blue 1 Lake in Grandma's Approved bath bombs. This ingredient has one job and that is to make things blue.
