Aromatic Solvents · European Industrial Supply
A high-solvency C10 aromatic fluid for coatings, agrochemical formulation, foundry resin systems, fuel additive packages, and oilfield chemistry. Available in two grades: standard and naphthalene-depleted (ND). Choosing the wrong grade has direct CLP labelling and formulation consequences. The distinction is covered in detail on this page.
Two Distinct Grades
Standard and ND variants have different naphthalene content, regulatory classification and CLP hazard profiles. Grade selection matters.

Naphthalene Content Is the Key Variable
The standard grade carries around 7 wt% naphthalene and a Carcinogenicity Cat. 2 classification (H351). The ND grade reduces this to below 1 wt% and avoids that classification. This affects labelling, formulation approval, and downstream compliance, not a minor difference.
High Flash Point, Class 3 Flammable Liquid
Both grades have a flash point above 60°C, classifying them as Flammable Liquid Category 3 under CLP. Transport as UN 3082 Class 9, Packing Group III. Marine pollutant status applies to both grades.
C10 Aromatic, Higher Boiling Than the 100 Grade
The 150 grade family is a heavier C10 aromatic cut than the C9-based 100 grade. Higher boiling range, slower evaporation, and higher density. The right grade family depends on the application's solvency, evaporation, and flash point requirements.
SDS and TDS Provided Before Supply
Current, CLP-compliant Safety Data Sheets and Technical Data Sheets for both variants are available at inquiry. Handled across established European supply routes, Belgium, the Netherlands, Germany, France, and the United Kingdom.
Product Overview
Aromatic solvent naphtha 150 is a high-solvency C10 aromatic fluid used in coatings, agrochemical formulation, foundry resin binder systems, fuel additive packages, and oilfield chemistry. It sits above the 100 grade in boiling range and evaporation speed, with a flash point above 60°C that places it in a different transport category from its lighter counterpart.
The commercially and regulatorily significant decision for buyers is not which product family to use, it is which grade within that family. The standard grade contains around 7 wt% naphthalene, which drives a Carcinogenicity Category 2 classification under CLP. The naphthalene-depleted (ND) grade reduces this well below 1 wt% and does not carry that classification. This is not a minor difference.
The ND grade is increasingly preferred in European coatings and agricultural formulation markets where the H351 classification creates formulation, labelling, or downstream compliance complications. The standard grade remains relevant where naphthalene content is not a constraint, including foundry chemistry and certain oilfield applications.
If your question is which aromatic grade family fits your application, our aromatic solvent naphtha 100 page covers the lighter C9 grade. For the broader regulatory context, see our aromatic solvents and cumene regulation guide.
Standard Grade
High-solvency C10 aromatic fluid. Naphthalene content approximately 7 wt%. Carries Carcinogenicity Cat. 2 (H351) under CLP. Used where naphthalene content is not a formulation or regulatory constraint. Foundry resin, oilfield chemistry, and certain coatings applications remain active end-use sectors.
Naphthalene-Depleted (ND) Grade
Naphthalene-depleted variant of the same product family. Naphthalene content below 1 wt%. Does not carry Carcinogenicity Cat. 2 classification. Preferred in coatings, agricultural formulation, and any application where H351 classification creates downstream labelling or formulation constraints under EU or UK regulatory frameworks.
Where Caution Is Needed
Both grades are aromatic solvents with a different hazard profile than dearomatised alternatives. The choice between standard and ND requires a deliberate regulatory assessment, it is not a default decision. Buyers should confirm the appropriate grade with their EHS or regulatory function before specifying at scale.
Sourcing Both Grades
Both variants are handled within our established network. When submitting an inquiry, specify which grade variant is relevant, or ask us to confirm which is the more commercially available option for your volume, delivery location, and timeline. We will answer directly.
Technical Specifications
Typical reference data for both grades shown together. All values are indicative; they are not specification limits. The naphthalene column is the critical differentiator for regulatory and formulation decisions.
All values are indicative typical properties drawn from producer reference documentation. They are not specification limits and may vary by source, batch, and producer. The naphthalene content figures in particular should always be verified against the current Certificate of Analysis and Safety Data Sheet for the specific supply parcel under consideration. Some grades in this family may contain a stabiliser additive (BHT); confirm with the relevant supplier documentation.
Regulatory Classification
The two grades share most of their CLP classification. The critical difference is the Carcinogenicity Cat. 2 classification carried by the standard grade due to its naphthalene content. This affects labelling, downstream formulation obligations, and workplace risk assessments.
Standard Grade, CLP Classification
Aspiration Toxicity Cat. 1 (H304)
STOT Single Exposure Cat. 3, narcosis (H336)
Carcinogenicity Cat. 2 (H351) Carc. 2
Aquatic Chronic Cat. 2 (H411)
EUH066
Signal word: Danger. The H351 classification arises from the naphthalene content of approximately 7 wt%. This has direct implications for labelling, downstream formulation, and workplace health risk assessment obligations.
Naphthalene-Depleted Grade, CLP Classification
Aspiration Toxicity Cat. 1 (H304)
STOT Single Exposure Cat. 3, narcosis (H336)
Aquatic Chronic Cat. 2 (H411)
EUH066
No H351
Signal word: Danger. The Carcinogenicity Cat. 2 classification does not apply. The ND grade is otherwise handled with the same hazard precautions applicable to aromatic solvent fractions in this boiling range. Always verify against the current SDS for the specific offered source.
Transport Classification, Both Grades
UN Number 3082 (Environmentally Hazardous Substance, liquid, n.o.s.). Packing Group III. ADR/IMDG Class 9. Marine Pollutant: Yes. Both grades carry marine pollutant status. Transport documentation must reflect this when applicable. Classification Code: M6.
Why the Naphthalene Distinction Matters
Naphthalene is classified as a Carc. 2 substance under Annex VI of CLP. When present above the generic concentration limit in a mixture, it triggers the Carc. 2 label element on the finished formulation. For buyers producing coatings, crop protection formulations, or consumer-adjacent products under EU or UK frameworks, this creates direct labelling obligations and may prevent the product's use in certain formulations. The ND grade was developed to address this constraint directly.
REACH Compliance
Both grades are handled within supply chains operating under REACH. Substances are registered where required; Safety Data Sheets are prepared in accordance with Regulation (EC) No 1907/2006 and current CLP classification. For buyers operating under UK REACH, documentation is aligned to UK regulatory requirements rather than EU equivalents.
Regulatory Verification
The classification information above is based on producer reference documentation current at the time of this page's preparation. Classification is subject to change and must always be verified against the current, source-specific Safety Data Sheet before use in any regulated application. Current SDS for both variants is supplied by the source at the inquiry stage.
Applications
Both grades serve similar application sectors. Grade selection within the family is driven by the regulatory and formulation constraints of the specific application rather than by solvency or performance differences.
Industrial and Protective Coatings
High aromatic solvency for alkyd, epoxy, and chlorinated rubber systems where medium-slow evaporation and strong resin compatibility are relevant. The ND grade is increasingly preferred in EU coatings formulation where H351 creates labelling or formulation constraints under VOC and CLP frameworks.
Grade note: ND preferred where H351 is a constraint. Standard grade applicable where naphthalene content is not regulated in the end-use context.
Agricultural Chemical Formulation
Carrier solvent in emulsifiable concentrate (EC) formulations for crop protection products. Aromatic solvency, viscosity behaviour, and emulsification compatibility are the principal formulation parameters. The ND grade avoids H351 labelling obligations that complicate downstream classification in EU markets.
Grade note: ND generally preferred in agrochemical formulation under EU regulatory frameworks.
Foundry Resin Binder Systems
Solvent component in phenolic and furan resin binder systems used in sand casting operations. The standard grade is frequently cited in foundry applications where solvency profile, resin compatibility, and naphthalene content are specifically handled within the occupational health and safety framework of the foundry environment.
Grade note: Standard grade historically used in foundry chemistry. Verify current occupational exposure requirements for naphthalene before specifying.
Fuel and Combustion Additive Packages
Aromatic solvent carrier in fuel additive concentrates where aromatic compatibility and a controlled flash point above 60°C are operational requirements. Packaging, transport classification, and marine pollutant labelling must be addressed in the supply chain documentation.
Grade note: Confirm grade-specific requirements with the additive package formulator. Both variants discussed at inquiry.
Oilfield and Refinery Chemistry
Applied in production chemical packages, pipeline treatment chemistry, and refinery process applications where aromatic solvency, compatibility with hydrocarbon streams, and a higher flash point than lighter aromatic grades are relevant parameters. Documentation requirements are typically more extensive in this sector.
Grade note: Both grades discussed at inquiry. Confirm grade preference and document requirements when submitting.
Printing Inks and Specialist Industrial Chemistry
Applicable in publication gravure and specialty inks where resin solubility and evaporation balance are commercially more important than low-odour positioning, and where the boiling range of the 150 family provides a better match than the lighter 100 grade.
Grade note: Application suitability is system-specific. Confirm which grade variant is appropriate before specifying at scale.
Working With Us
The fastest path to a commercially useful answer is a specific inquiry. Here is what helps.
Specify the Grade Variant
If you know whether you need the standard or the naphthalene-depleted grade, say so directly in your inquiry. If you are not yet sure which applies to your formulation or end-use context, tell us the application and we will help frame the question, but the regulatory decision belongs with your technical or EHS team.
What to Include
Target volume and frequency, delivery country or specific site, pack format preference where relevant, application context if you can share it, and any documentation your supplier approval or onboarding process requires. If the inquiry is at an early evaluation stage, say so, we respond to qualification inquiries directly.
What You Receive
A direct commercial reply from the relevant supplier in the network confirming whether supply can be arranged for the grade variant and volume in question, what documentation is available, an indicative pricing position where we are able to offer one, and any information we still need to progress to a formal offer.
What We Do Not Do
We do not recommend grade selection on behalf of buyers where the choice has regulatory consequences. We provide the commercial and product-family context. The formulation and compliance decision belongs with the buyer's technical and EHS function and must be made against the current SDS for the specific source offered.
Procurement FAQ
These are the recurring questions around the 150 grade family. The naphthalene question comes up in most serious inquiries.
What exactly is the difference between the standard and ND grade?
The primary difference is naphthalene content. The standard grade contains approximately 7 wt% naphthalene and carries a Carcinogenicity Cat. 2 classification (H351) under CLP. The ND grade reduces naphthalene to below 1 wt% and does not carry this classification. Both grades have otherwise similar solvency characteristics and boiling ranges. The ND grade has a slightly narrower distillation cut.
Which grade should we specify for European coatings or agricultural applications?
The ND grade is increasingly the default in European coatings and agrochemical formulation markets precisely because H351 creates downstream classification, labelling, and compliance complications. That said, grade selection must be confirmed with your EHS or regulatory team against the specific application and the current SDS for the offered source. We can provide the documentation; the compliance decision belongs with you.
Is this the same as the 100 grade family?
No. The 150 family is a heavier C10 aromatic cut. It has a higher flash point (above 60°C vs. approximately 50°C for the 100 grade), a higher boiling range, slower evaporation, and higher density. The two grades are used in overlapping but distinct application contexts. If you are deciding between them, the flash point classification difference (Class 3 vs. Class 3 but at different temperatures) and the evaporation rate are often the deciding factors.
Can we receive SDS and TDS for both variants before committing to an order?
Yes. Current Safety Data Sheets and Technical Data Sheets for both grades are provided during the inquiry and qualification stage. Documentation is not held back until after an order is confirmed.
