COSA PUR 88 is a specialist CIP additive for silicone oil and fatty process residues. It is used with alkaline cleaning solutions to improve removal and suspension of difficult silicone contamination in pharmaceutical and cosmetic equipment.
Key features and benefits
- Specialist performance against silicone oil residues.
- Effective against fatty and hard-to-clean silicone soils.
- High soil-suspending power.
- Designed as an additive for alkaline cleaning solutions.
- Supported by Ecolab validation and residue-analysis documentation.
Applications
- General CIP for homogenisers, pipelines and tanks.
- Typically 1-2% alkaline COSA CIP solution plus 1-2% COSA PUR 88.
- Typical temperature range is 65-85 C; below 65 C, foam may form.
- Final rinsing is most effective below 40 C using water of minimum drinking-water quality.
