Caustic Soda = Volatile Price & Volatile Chemistry.


Caustic Soda is a HIGHLY CORROSIVE CHEMICAL listed on the Special Health Hazard Substance List. Caustic Soda on contact can burn the skin and the eyes and can cause permanent lung damage through inhalation. Caustic soda in contact with water can create enough heat to ignite combustibles and the resulting fire will produce poisonous gases. THIOGUARD® and THIOGUARD® ΩMEGA-S technical grade magnesium hydroxide is an effective, non-hazardous alternative to Caustic Soda. By converting to THIOGUARD®, wastewater utilities are able to eliminate hundreds of hazardous bulk tanker truck deliveries, thereby reducing insurance costs.

In addition, Caustic Soda freezes at a temperature of 52 degrees, rendering it useless for water treatment purposes, and creating additional hazards by creating increased pressure at valves with the potential unexpected eruptions or spills. When it comes to safety, Thioguard and Thioguard Omega-S technical grade magnesium hydroxide is clearly superior.

  • Caustic Soda (Sodium Hydroxide) is hazardous to use, detrimental to personnel safety and biological processes
  • Sodium addition to wastewater upsets flocculation, settling, clarification and dewatering processes, driving up needs for polymer or metal salt use.


Caustic Soda is pricing is subject to a variety of pressures, from basic supply and demand issues to market manipulation – even international trade can cause price fluctuations. THIOGUARD® technical grade magnesium hydroxide offers greater “price reliability,” and delivers a safe and effective alternative to Caustic Soda.

  • Budget Uncertainty
  • Challenging Contract Management when driven to force majeure re-pricing

THIOGUARD® is a better, safe alternative to Caustic Soda.
