Caustic Soda Pearl - 25kg

Caustic Soda Pearl - 25kg

Caustic Soda Pearl is designed for CIP, Soak and bottle-washing applications in Breweries, Dairies and Food Processing plants; it is also suitable for use in other high-care applications. For optimum performance, it is blended with an additive from the Adhol range or Holchel. These additives contain sequestrants that inhibit and dissolve mineral scale and enhance the performance of the Caustic Soda solution. It is not suitable for use on Aluminium, Zinc, Copper or their alloys.

USE INSTRUCTIONS

• In use concentrations of Caustic Soda Pearl are application dependent and should be established during trials.
• A 1% w/v solution gives approximately 1% w/v causticity (1% w/v NaOH).
• Cleaning temperatures should be optimised during trials. Temperature above 90°C can be used for fatty or heavily carbonised soils. However, for protein soils, it is often more effective to clean at lower temperatures (up to 70°C).
• Caustic Soda Pearl 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.
NOTE: When Caustic Soda Pearl is dissolved in water, heat is generated, and at high strengths, an acrid vapour can be released.

CIP. For Clean in Place applications, 1% to 5% w/v solutions of Caustic Soda Pearl are typically circulated for 20 – 30 minutes. 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 by additives such as Adhol No.10. Caustic Soda Pearl is compatible with Adhol No.10, but advice on procedures should be sought.
In hard water areas, or for soils with a high mineral content such as Milkstone or Beerstone, it is advisable to use in conjunction with an additive such as Holchel.

Bottlewashing. Caustic Soda Pearl can be used as a bottle-washing detergent at 0.4% to 0.5% w/v solution, depending on the nature of the soiling. An Adhol additive or Holchel will improve compatibility with hard water and soil suspensions.
