Steps:
If you are a customer, request it directly from your supplier – they are legally obligated to provide the latest SDS. acticide mkw2 sds updated
Under GHS, in-house labels on secondary containers (squirt bottles, mixing tanks) must match the updated SDS. Ensure your label printer reflects:
If you suspect an SDS is incorrect or outdated:
Do not rely on third-party websites. Always source the SDS from: Do not rely on third-party websites

The most significant changes are in Section 2: Hazards Identification. The updated SDS reflects stricter sensitization thresholds.
| Hazard Class | Previous Version (2020) | Updated Version (2025) | | :--- | :--- | :--- | | Skin Sensitization | Category 1 (Warning) | Category 1A (Danger) – Strong sensitizer | | Aquatic Acute Toxicity | Category 1 (Warning) | Category 1 (Warning – unchanged but stricter M-factors) | | Specific Target Organ Toxicity (STOT SE 3) | Respiratory irritation | Respiratory irritation + additional pulmonary effects | If you are a customer, request it directly
Why the change? The European Chemicals Agency (ECHA) has re-evaluated CMIT/MIT mixtures. New epidemiological data from paint manufacturing plants showed higher-than-expected rates of occupational contact dermatitis and respiratory sensitization (asthma). Hence, the "Danger" signal word is now mandatory.
When an SDS is "updated," the core chemistry rarely changes, but the hazard communication does. Based on the 2024–2025 regulatory cycles (GHS Rev. 9 and EU CLP ATP updates), here are the typical critical updates found in the latest Acticide MKW2 SDS.
When comparing the old vs. new Acticide MKW2 SDS, focus on Section 2 (Hazards Identification) and Section 15 (Regulatory Information).
| Section | What may change | |---------|----------------| | 2 – H&S Statements | Addition of EUH208 (Contains BIT – May produce allergic reaction) or revised P-phrases | | 3 – Composition | Exact % ranges of BIT, MIT, Bronopol (if disclosed) | | 8 – Exposure controls | New occupational exposure limits (OELs) for Bronopol or MIT | | 11 – Toxicology | Skin sensitization category (Cat. 1 or 1A/1B) | | 14 – Transport | UN number or packing group (rare but possible) | | 15 – Regulatory | New restrictions (e.g., EU Biocidal Products Regulation (BPR) update, or MIT concentration limits) |
Example: A 2023–2024 update likely tightens labeling for skin sensitization due to MIT/Bronopol.
