  • Carboxymethylcellulose sodium
  • Food Blue No. 1
  • Parfume
  • Fatty acids, coco
  • Lipase

Ingredient Analysis


✅ Septic-Safe or Generally Acceptable Ingredients:

  • Sodium Sulphate – Common filler; water-soluble and typically safe in small amounts.

  • Sodium hydrogencarbonate (baking soda) – Mild, natural cleaner and deodorizer; septic-safe.

  • Carboxymethylcellulose sodium – Biodegradable thickener; generally safe.

  • Fatty acids, coco – Plant-based surfactant; biodegradable and generally septic-friendly.

  • Lipase, Subtilisin, Cellulase, Amylase – Enzymes that help break down organic matter; these can support digestion within a septic tank.

  • Triacylglycerol – Naturally occurring in fats; not harmful to the system.

⚠️ Ingredients of Concern:

  • Sodium dodecylbenzenesulfonate – A synthetic surfactant that is harsh and not easily biodegradable. It’s toxic to aquatic organisms and can disrupt septic tank bacteria, especially with repeated use.

  • Food Blue No. 1 – Synthetic dye; not biodegradable and can accumulate in the tank.

  • Parfume – A vague term often indicating synthetic fragrance blends, which may contain non-biodegradable compounds or small amounts of antimicrobials.

Verdict: Safe or Unsafe for Septic Systems?


⚠️ Use With Caution — Not Ideal for Regular Septic System Use

While Vacplus contains several septic-friendly enzymes and natural surfactants, its use of sodium dodecylbenzenesulfonate, synthetic dyes, and fragrance additives means that frequent or excessive use may harm your septic system. Additionally, its tablet form delivers a constant release of these compounds into your tank, increasing the risk to bacterial health over time.

It’s best to steer clear of automatic toilet tablets—especially those with unclear ingredient lists or formulas that haven’t been reviewed or approved by septic system experts. While convenient, these tablets often release harsh compounds continuously, which can disrupt the bacterial balance in your tank. Opt for liquid, plant-based, biodegradable cleaners with fully disclosed ingredients and no synthetic surfactants or antibacterial agents.
