Causeda is a sequestered caustic soda solution which keeps down beerstone and is suitable for the CIP. Ideal for hard water areas.
This product is a hazardous material, therefore an additional delivery surcharge will be added to the order.
Causdeta 25 contains Caustic Soda (NaOH), EDTA and a synergic blend of other scale control agents. This makes it
suitable for cleaning soils with a high mineral content where products such as Caustak 25 or Caustak 30 may not be
Causdeta 25 is formulated to be low foaming, enabling it to be used in recirculation applications. It is designed
primarily for applications in Breweries, Beverage, Dairies and Food Processing plants. Causdeta 25 is also suitable
for use in other high care industries.
Causdeta 25 has a very low freezing point (< -10°C); this is much lower than higher strength caustic detergents.
Causdeta 25 is ideal for applications where product is stored outside during the winter or for unheated bulk
In use concentrations of Causdeta 25 are application dependent and should be established during trials.
A 1% solution will give approximately 0.32% w/v causticity (0.32% w/v NaOH) and is compatible with at least 130
ppm of water hardness.
Cleaning temperatures should be optimised during trials. For fatty or heavily carbonised soils, temperatures above
90°C can be used. However, for protein soils, it is often more effective to clean at lower temperatures (up to 70°C).
Causdeta 25 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.
For Cleaning in Place applications, Causdeta 25 is typically circulated for 20 – 30 minutes at 1% to 5% v/v. For soils with a very high mineral content (milkstone etc), it is advisable to validate trial cleans by checking for the presence of free EDTA at the end of cleaning. Ideally at the end of cleaning there should be a minimum of 200 ppm free EDTA present (Test Kits for free EDTA are available from Holchem). Before circulating the detergent, pre-rinsing with water is advisable. After cleaning, the circulation loop should be flushed with water until the pH or conductivity of the rinsings is approximately equal to that of the water. Cooking Vessel Boil-out. Causdeta 25 is used to boil-out cooking vessels to remove carbonised and mineralised product residues. Typically concentrations will be between 1% to 3% v/v at up to 100°C. The cooking vessel is typically boiled for 30 minutes with the detergent.
Fryer Boil-out. Causdeta 25 is used to boil-out oil fryers to remove the carbonised oil and product residues. Typical use strengths are 1% to 5% v/v. The fryer is typically boiled for 1 to 2 hours with the detergent.
Traywashing. Causdeta 25 is used as a traywash detergent at 0.5% to 2% v/v solution.
