TCP – Tricresyl Phosphate (industrial)
Lubricant/coatings • handle with care
| Parameter | Typical | Spec |
|---|---|---|
| Assay (TCP) | ≥ 99.0% | ≥ 98.5% |
| Acid value | ≤ 0.20 mg KOH/g | ≤ 0.30 mg KOH/g |
| Water | ≤ 0.10% | ≤ 0.20% |
| Color (APHA) | ≤ 80 | ≤ 150 |
| Chlorine (as Cl) | ≤ 100 ppm | ≤ 200 ppm |
| Odor | characteristic, mild | — |
| Parameter | Typical | Spec |
|---|---|---|
| Assay (TCP) | ≥ 99.5% | ≥ 99.0% |
| Acid value | ≤ 0.10 mg KOH/g | ≤ 0.15 mg KOH/g |
| Water (Karl Fischer) | ≤ 0.05% | ≤ 0.10% |
| Color (APHA) | ≤ 50 | ≤ 80 |
| Ortho isomers (Σ‑o‑TCP) | low‑ortho (typ. ≤ 0.10%) | program‑/supplier‑specific |
Low‑ortho programs limit ortho‑substituted TCP content; exact limits depend on supplier and region. If you need a specific Σ‑o‑TCP or TOCP threshold, specify it in the RFQ.
| Framework | Status | Notes |
|---|---|---|
| Substance class | Aryl phosphate | not a phthalate |
| REACH | Registered/Notified (supplier‑specific) | confirm tonnage/uses for dossier coverage |
| Toys/Childcare | Not supplied | use prohibited or unsuitable |
| Food‑contact/Cosmetic | Not supplied | not intended for these applications |
| Other regional rules | Program‑dependent | provide end‑use and jurisdiction for review |
Regulatory status varies by region and end‑use. Some jurisdictions limit ortho‑isomer content or TCP use in consumer products. Provide your application and location so we can confirm eligibility.
| Item | Status | Notes |
|---|---|---|
| DG classification | Typically non‑DG liquid | verify per route/carrier |
| Handling | avoid skin contact and aerosols | use closed transfers; local exhaust ventilation |
| Incompatibilities | strong oxidizers; strong bases | see SDS |
| PPE | chemical‑resistant gloves, goggles, protective clothing | follow SDS and IH guidance |
| Toxicology note | ortho isomers | TOCP is associated with delayed neurotoxicity; manage exposure and specify low‑ortho grades as needed |
| Spills/Disposal | absorb with inert material | prevent release; dispose per local regulations |
Always consult the SDS. Store sealed, cool, and out of sunlight. Record acid/water/color and, where relevant, Σ‑o‑TCP on receipt; maintain traceability.
| Applications | Packaging | Storage & Handling |
|---|---|---|
|
• Antiwear/extreme‑pressure additive for lubricants.
• Flame‑retardant plasticizer in specialty coatings/adhesives. • Other industrial uses where allowed by law and SDS. |
• 200 kg coated steel drums; 1,000 kg IBCs.
• 20–25 kg pails for sampling/R&D. • Custom packaging and nitrogen blanketing on request. |
• Store cool, dry; protect from light.
• Keep containers tightly closed; use closed transfers. • Maintain compliance records (end‑use, region, Σ‑o‑TCP spec if applicable). |
