• Titanium Dioxide

Ingredient Analysis

✅Septic-Safe or Generally Acceptable Ingredients:

• Sodium Carboxymethyl Cellulose – A biodegradable thickener often used in cleaning and food products; septic-safe.

• Titanium Dioxide – An inert whitening agent; not biodegradable, but generally considered safe in small amounts due to low toxicity.

⚠️Ingredients of Concern:

• Sodium Hydrosulfite – A strong reducing agent used for rust removal; not ideal for septic systems as it may harm beneficial bacteria.

• Sodium Lauryl Sulfate (SLS) – A harsh surfactant; biodegradable but can disrupt septic bacteria with frequent exposure.

• Amides – A broad class of compounds; depending on the specific type, may range from mildly irritating to environmentally persistent.

• Bicyclo[2.2.1]heptan-2-ol – Likely used as a fragrance carrier or solvent; limited safety data and unclear impact on septic systems.

• Fragrance – Unspecified synthetic compounds can include antimicrobials or non-biodegradable elements.

Methanol – A toxic alcohol; harmful to aquatic life and can inhibit septic tank microbes even in small amounts.
