Sodium Hydroxide (Lye / Caustic Soda)
Not used — health & safety concerns
Sodium hydroxide — lye, caustic soda — is a strong base used as the active ingredient in drain cleaners, oven cleaners, and some heavy-duty degreasers. It causes severe chemical burns on contact with skin, eyes, and mucous membranes. This page covers what sodium hydroxide is, where it appears in household products, safety considerations, and why Natural Flower Power does not use it in any formulation.
