D100 Dearomatized Solvent · European B2B Sourcing
D100 is typically evaluated when buyers need a flash point clearly above 100°C, and where D80's ~74°C minimum is not sufficient for the site, process or regulatory requirement. The key questions are commercial as well as technical: is the grade available, does the specification support approval, and is the supply route workable for your destination and volume.
Availability, pricing and grade positioning can shift quickly depending on refinery output, seasonal demand and market conditions. Buyers typically validate early to avoid requalification or supply disruption.
Used by purchasing managers, formulators and distributors who need a fast commercial answer before moving into approval or reformulation.
Comparing with a lighter option? See the D80 page (~min 74°C) or the D-cuts guide. Need an even higher flash point? See the D120 page (~min 110°C) or the D140 page (~min 129°C).

What you typically want from a D100 enquiry
A good first response should immediately tell you whether the requirement is workable, what the real market position is, and whether the grade can actually be supplied under current conditions.
At a glance
Product fit
D100 is usually considered when D80 does not provide enough flash-point headroom for the site, process or regulatory framework. The indicative specification points to a minimum flash point of ~101°C and a distillation window from ~230°C initial boiling point up to ~270°C final boiling point. In practice, that makes D100 relevant for metalworking fluids, mold release and industrial process applications where a very high-flash dearomatized solvent is a hard requirement.
In practice, most wrong solvent selections start from the grade name instead of the operational constraint, validating this early typically avoids requalification delays, internal rejection or unnecessary formulation work.
Choose D100 when
Your site, formulation or compliance framework requires a flash point clearly above ~100°C and D80's ~74°C minimum is not sufficient.
Think twice when
D80 already meets your flash-point requirement. Moving to D100 without a clear technical reason adds cost without proportional benefit. Also check aromatic content, D100's ~0.9 wt% max is higher than D80's ~0.20 wt%.
Move to D120 when
Even ~101°C is not enough. D120 pushes the flash point to a minimum of ~110°C with a heavier distillation profile for the most demanding applications.
Always verify
Final fit depends on formulation, process, compliance and the actual specification being quoted. D100 should never be approved on grade name alone.

Grade context
This is not a producer specification table. It is a commercial buying guide to help frame whether D100 is the right discussion for your requirement.
| Decision point | D100 | D80 | D60 |
|---|---|---|---|
| Typical buying logic | Very high flash, very slowWhen D80 is not heavy enough and a flash point above ~100°C is a hard requirement. | High flash, controlledOften chosen when a clearly high flash point is needed but ~101°C is not strictly required. | Moderate flashOften the starting point when a flash point above ~60°C is acceptable and faster evaporation is tolerated. |
| Flash-point direction | Indicative spec ~min 101°C, clearly above 100°C. | Indicative spec ~min 74°C. | Commonly above ~60°C. |
| Evaporation direction | Very slow, heavier distillation range than D80. | Slow, slower than D60, faster than D100. | Faster than D80 and D100. |
| Aromatic content | ~max 0.9 wt%, higher than D80. | ~max 0.20 wt%. | ~max 0.10 wt% (sales spec). |
| Typical buyer question | "Does our site or process specifically require a flash point above ~100°C?" | "Is ~74°C enough, or do we need the extra headroom that D100 provides?" | "Is D60 heavy enough, or does our compliance framework require more?" |

Applications
D100 is most relevant where flash-point compliance drives the grade selection rather than evaporation speed or odour profile alone. Application suitability is the buyer's responsibility to verify.
Metalworking
Metalworking fluids and process oils
Frequently discussed for metalworking fluid formulations where a very high flash point is a safety or regulatory requirement and D80 falls short of the threshold.
Mold release
High-flash release-agent formulations
Relevant in release-agent systems where processing temperatures or site rules require a solvent carrier clearly above ~100°C flash point.
Cleaning
High-flash industrial cleaning
Process cleaning and maintenance applications review D100 when a very high-flash, low-aromatic dearomatized route is specifically required.
Coatings
Slow-drying coatings and process fluids
Used in coatings and formulation discussions where a very high flash point and slow evaporation are both relevant selection criteria.
Blanket wash
High-flash blanket-wash discussions
Can appear in blanket-wash discussions where the press environment or fire safety rules push the flash-point requirement above what D80 can provide.
Aerosols
Process and aerosol-system discussions
Less common than lighter grades but can appear in aerosol or delivery-system discussions where process temperature or safety rules require a very high flash point.
Consumer products
Consumer and maintenance formulations
Can appear in consumer-product discussions, always subject to suitability, compliance and documentation review for the intended market and jurisdiction.
General
General industrial blending
Also used by distributors and formulators who need a reliable very high-flash D100 sourcing route for ongoing European industrial demand.
Buying checklist
The fastest route to a good D100 decision is to confirm the flash-point requirement first, then check distillation fit, aromatic tolerance and documentation before going deep into price discussions.
Most incorrect solvent selections come from starting with the grade name instead of the process constraint, validating this early typically avoids requalification delays, internal rejection or unnecessary formulation work.
Supply logic
The most useful quotation discussions are the ones where packaging format is aligned with actual usage, delivery geography and unloading reality.
Bulk tanker
Usually the most economical route for larger industrial demand and recurring consumption. Best when the site is equipped for unloading and the requirement is commercially large enough to justify tanker logistics.
IBC supply
Makes sense for mid-range volumes, qualification work, multi-site demand or buyers who want flexibility without immediately committing to full bulk handling.
Drums
Relevant for smaller volumes, more fragmented demand or sites where access, storage or handling rules make drums more practical than IBC or tanker supply.
FAQ
Is D100 the same from every supplier?
No. D100 refers to a recognizable grade band, but exact aromatic content, distillation behaviour and documentation can vary by source and supply route. Always review the current sales specification for the quoted material.
What is D100 usually used for?
Common discussions include metalworking fluids, mold release, industrial cleaning and coatings where a flash point clearly above ~100°C is a hard requirement and D80 does not provide sufficient headroom.
Can D100 be supplied in bulk, IBC and drums?
Yes, depending on volume, route and current supply position. Bulk is often the most logical for larger quantities. IBC and drum options can be discussed where the route and packaging format make sense.
What flash point and boiling range should buyers expect?
The indicative D100 snapshot on this page shows a minimum flash point of ~101°C, minimum initial boiling point of ~230°C and maximum final boiling point of ~270°C. Actual quoted documentation always governs.
How does D100 compare to D80 and D120?
D100 sits between D80 (~min 74°C flash point) and D120 (~min 110°C flash point). If D80 meets your flash-point requirement, D100 may not be necessary. If ~101°C is still not sufficient, D120 is the next grade to review. See the full D-cuts guide for the complete picture.
Do you provide SDS and current specification?
Yes. Current sales specification and SDS can be shared during the quotation process, subject to the actual supply route and available producer documentation.
Is D100 always available in Europe?
No. Availability depends on refinery output, seasonal demand and allocation. In tighter markets, D100 can become limited or shift significantly in price week-to-week. Buyers typically validate availability early rather than assuming continuity.
What is the price of D100 in Europe?
D100 pricing depends on refinery output, availability, volume, delivery location and packaging format. Prices can move weekly. Most buyers request a current quotation rather than relying on historic price levels.
