Part 16: Other Information (Revision Date & Key to Abbreviations)
Ensure the MSDS you have is no more than 3 years old. Current Nalco Water SDS documents are updated to reflect changes in GHS classifications or formulation adjustments.
- Acidic – requires PPE during handling
- Moderate aquatic toxicity – cannot be discharged directly into rivers/ponds
- Can degrade at very high temperatures (>150°F) to form orthophosphate (potential calcium phosphate scale)
- Proprietary formula – difficult to substitute or blend with other chemicals without compatibility testing
⚠️ Disclaimer: This review is based on publicly available and typical SDS information for Nalco 73385. Always obtain and read the actual SDS provided by Nalco/Ecolab for the specific batch you are using, as formulations can change without notice.
