What is Fuugu made from, and is it bleach-free?

Fuugu is a foaming toilet bowl cleaning powder packed in individually sealed, pre-measured bags. It is formulated without chlorine bleach, ammonia, and quaternary ammonium compounds, also known as quats. It is also septic-safe when used as directed.

The formula also uses a natural dye engineered to reduce the likelihood of leaving residue on porcelain during normal use.
