Q2: Can I store NALCO 77225 in a stainless steel tank?

A: The UPD indicates 316 stainless steel is acceptable for storage, but 304 SS may pit over time. Use polyethylene for long-term storage.

Q3: My old SDS says “Irritant,” but the UPD says “Danger – Corrosive.” Why?

A: Nalco may have increased the concentration of sodium hydroxide or added a more aggressive polymer to improve performance. The UPD reflects the new formulation and its more severe hazard profile.

8. Frequently Asked Questions (FAQ) About Nalco 77225 SDS UPD

Q: Is Nalco 77225 considered hazardous?
A: Yes. According to the UPD SDS, it is a skin and eye irritant/corrosive and toxic to aquatic life.

Q: Does the “UPD” change the storage requirements?
A: Possibly. Always cross‑check Section 7. Some updates add temperature limits or specific incompatibility warnings.

Q: Can I use an older SDS if I still have the old formula bottle?
A: No. Even legacy inventory requires the current SDS, because the hazard communication standard applies to the product identifier, not the batch date. Product Identification : Product name, synonyms, and CAS

Q: How often does Nalco release UPD SDSs for 77225?
A: On average, every 18–24 months, but significant regulatory changes (e.g., EU CLP update) can trigger an earlier revision.
