Important Notice Regarding "MSDS" vs. SDS: Under the Globally Harmonized System (GHS), Material Safety Data Sheets (MSDS) have been replaced by Safety Data Sheets (SDS). Regulatory bodies like OSHA (in the US) and ECHA (in the EU) now require the 16-section SDS format. Therefore, while this report references historical MSDS data, it is structured as a modern SDS compliance report.

Action item: Verify that your on-site SDS binder has a revision date within the last 3 years. As of 2025, the latest revision for NALCO 77352 is likely dated 2023 or 2024.
While the exact proprietary formulation is confidential, the SDS for Nalco 77352 will list hazardous ingredients above their reporting thresholds. Typical components include:
| Chemical Name | CAS Number | Typical % (Range) | Function | |---------------|------------|-------------------|-----------| | Phosphoric acid, (1-hydroxyethylidene)bis- (HEDP) | 2809-21-4 | 10-30% | Corrosion inhibitor | | Phosphonic acid, (nitrilotris(methylene))tris- (ATMP) | 6419-19-8 | 5-15% | Scale inhibitor | | Acrylic copolymer | Proprietary | 5-20% | Dispersant | | Sodium hydroxide (pH adjuster) | 1310-73-2 | 1-5% | Corrosive potential |
Note to industrial hygienists: The exact percentages are trade secrets. However, the SDS must disclose any ingredient classified as hazardous and its approximate concentration.
A spill of Nalco 77352 requires immediate action due to its corrosive nature.
Small Spill: Absorb with inert material (sand, vermiculite, diatomaceous earth). Neutralize with sodium bicarbonate or soda ash if available. Place in sealed, compatible chemical waste container.
Large Spill: Evacuate non-essential personnel. Wear full PPE (neoprene or butyl rubber gloves, chemical splash goggles, face shield, acid-resistant apron and boots). Dike far ahead of spill to prevent entry into sewers, waterways, or groundwater. Neutralize carefully. Contact environmental authorities if release enters waterways.
Environmental precautions: This product is toxic to aquatic life. Do not allow to enter storm drains or surface waters. Chemical Safety Compliance Report: Nalco 77352 Date: October
