Caustic 32% - 30kg

Caustic 32% - 30kg

Caustic 32% is a concentrated caustic solution formulated to be low-foaming, enabling it to be used in recirculation applications. It is designed primarily for use in Breweries, Beverage, Dairy, and Food Processing plants, but it is also suitable for use in other high-care industries. Caustic 32% is suitable for adjusting the pH of effluent streams. It can also be used in conjunction with various Adhol products to provide a customised CIP detergent in Food, Beverage, and Dairy environments. Caustic 32% has a high freezing point (approx 5°C), so it must be protected from frost and wind chill during cold periods. Bulk tank systems must have trace heating, and pipework should be lagged and trace heated. Caustic 32%is produced using Food Codex Grade Sodium Hydroxide.

USE INSTRUCTIONS

• In-use concentrations of Caustic 32% are application-dependent and should be established during trials.
• Cleaning temperatures should be optimised during trials. Temperature above 90°C can be used for fatty or heavily carbonised soils.
• Caustic 32% is not suitable for direct food contact.
  

The following are typical example applications. Users should refer to Cleaning Instruction Cards for specific guidance. Other applications should be discussed with your Holchem Consultant.

CIP. For Clean in Place applications, Caustic 32% is typically circulated for 20 – 30 minutes at 0.5% to 3% v/v. The exact concentration is dependent on water hardness and soil type/level. Before circulating the detergent, pre-rinsing with water is advisable. After cleaning, the circulation loop should be flushed with clean water until the pH or conductivity of the rinsing is approximately equal to that of the water.
Occasionally, CIP cleans need to be boosted with additives such as Holchel or Adhol No.10. Caustic 32% is compatible with Adhol No. 10, but your Holchem consultant should advise on procedures.

Bottle Washing. Caustic 32% can be a bottle-washing detergent at a 0.75% to 1% v/v solution. Typical use at this temperature is around 80°C. Use with an Adhol additive will improve compatibility with hard water, label pulping, and soil suspension.

pH Adjustment. Caustic 32% is an economic means of adjusting the pH of acidic effluent streams. It is recommended that dosing be controlled automatically by an appropriate probe and pump system.

Other Applications. Caustic 32% is a versatile product. Other applications should be discussed with your Holchem Consultant.
