What Diisopropanolamine is used for
Diisopropanolamine (DIPA) is a white crystalline solid at room temperature, melting at 42 °C. Structurally it mirrors diethanolamine, but each hydroxyl-bearing carbon carries a methyl branch — the signature of the propylene-oxide-derived isopropanolamine family rather than the ethylene-oxide-derived ethanolamines.
DIPA is used industrially as an emulsifier, a stabilizer, and a general-purpose chemical intermediate. Like its isopropanolamine siblings, it is valued in formulation chemistry for neutralizing fatty-acid and sulfonic-acid-based surfactants and for its ability to dissolve oils and fats.
Where it sits among the isopropanolamines
- Monoisopropanolamine one hydroxyl, one amine — buffers and surfactant neutralization. See that page.
- Diisopropanolamine (this product) two hydroxyls, one amine — emulsifier, stabilizer, chemical intermediate.
- Triisopropanolamine three hydroxyls, no N–H — emulsifier/stabilizer and herbicide-acid neutralizer. See that page.
Appearance and handling character
Public hazard-classification data specific to this molecule is limited. We recommend handling DIPA with the standard precautions used for secondary amines — avoiding skin and eye contact and ensuring adequate ventilation — until your batch SDS confirms the specific classification.

How we supply Diisopropanolamine
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. DIPA's solid-at-room-temperature nature means handling format matters as much as price — that shapes how we manage this line.
We place your order with whichever qualified producer best matches your required grade, your price point and your preferred handling format — molten drum or flaked solid.
We keep a second qualified source on this line, so a single-plant disruption never becomes your production problem.
- Monoisopropanolamine content confirmed before we quote. Co-product carryover matters to downstream formulation performance.
- Molten or flaked solid supply arranged to your setup. We confirm your receiving and storage capability before booking.
- Documentation filed correctly. Every shipment carries correct, confirmed hazard and handling declarations.
- Scheduled call-off scheduling. We hold contracted tonnage and release it against your consumption calendar.
- Batch traceability to the producing plant. Full chain of custody documentation on request.
- Export machinery handled in-house. Classification, approved packing, labelling, freight booking and customs paperwork are ours to manage.

Trial / sample quantities
Small packs dispatched for formulation trials before a commercial order is placed.
Contracted call-off supply
We hold contracted tonnage and release it against your consumption calendar.
Handled with standard secondary-amine precautions
Comprehensive public GHS classification data for this specific molecule is limited; we handle it conservatively pending the SDS for your specific batch, which is the authoritative document.
Handling precautions
PPEChemical-resistant gloves and splash goggles recommended, as for any secondary amine.VENTAdequate ventilation when handling molten material.THERMFlash point of 135 °C — a moderate thermal hazard margin above typical handling temperature.
Always read the SDS issued with your specific batch. Treat skin and eye contact with the same caution used for other secondary alkanolamines until the batch SDS confirms the specific classification.
Storage
Store as a sealed solid at ambient temperature, or molten in heat-traced, insulated containers above its 42 °C melting point. Keep containers tightly closed to limit moisture pickup.
Handling
Use standard industrial hygiene — gloves, splash goggles, adequate ventilation — when handling molten material or dissolving the flaked solid.
Transport
We confirm and document the exact transport classification and any heating requirements for your specific shipment and destination.
Every batch, documented
We verify documentation before dispatch so there are no surprises at your incoming-goods bench.
Specification agreed
Assay and monoisopropanolamine content confirmed against your process requirement before order placement.
Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS and transport paperwork checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How diisopropanolamine is made
Diisopropanolamine belongs to the isopropanolamine family, produced industrially by the reaction of propylene oxide with ammonia — a shared production route that co-produces mono-, di- and triisopropanolamine in proportions controlled by the ammonia-to-propylene-oxide ratio, separated by fractional distillation.
We do not publish operating process parameters here; this is background only. Full technical and safety documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
