Q. We would like to have neutral foaming cleaning agent to clean fish oil and gelatin residue. We will also need a validatable method to test residue.
A. I recommend you evaluate Liquinox® Critical Cleaning Liquid Detergent. Liquinox is a neutral pH range, high foaming concentrated cleaner. You dilute it 1:100 or 10 mL/L to use it. For fish oil and gelatin I would use a hot solution to clean with followed by a hot rinse. I am sure you are aware that fish oil can have a very persistent odor.
Using a neutral range cleaner to remove fish oils, you may need to clean more than once, or you may need to clean once very thoroughly. You may need to use a very hot water solution for the best results. Be sure your first rinse is as hot or hotter than your cleaning solution so as to avoid hitting the surface with a cold rinse that will break the emulsion of residual oil and cause it to redeposit.
For automated cleaning requiring a low foaming detergent, we would recommend Alcojet® Low Foaming Powdered Detergent or Detojet® Low Foaming Liquid Detergent, depending on your needs for a powder or liquid concentrate respectively. These detergents employ oxidation cleaning mechanisms to help eliminate lingering organoleptic (odor) residues.
We are happy to discuss your process needs and provide residue detection methods for your specific needs at any time.
