COSA PUR 83 is a pigment-removal cleaner with strong dispersing performance. It can be used as the sole cleaning agent or as an additive to alkaline cleaning solutions for pharmaceutical and cosmetic CIP applications.
Key features and benefits
- Developed for pigment-containing process residues.
- High dispersing capacity based on organic-derived complexing agents.
- Can be used alone or as an additive to an alkaline COSA CIP cleaner.
- Surfactant-free and non-foaming.
- Can be controlled using conductivity and is supported by Ecolab validation documentation.
Applications
- General CIP for homogenisers, pipelines and tanks.
- Typically 1-3% COSA PUR 83, with an optional 1-3% COSA CIP solution.
- Typical temperature is 45-95 C when combined with COSA CIP, ideally 60-80 C; the stated standalone range is 5-95 C.
- Contact time depends on the type and degree of soiling.
