What Is Naphtha? Properties, Functions, & Safety Considerations
August 27, 2026
Naphtha is a petroleum-derived solvent valued for strong solvency and fast evaporation. VM&P naphtha, or varnish makers’ and painters’ naphtha, is commonly used in paints, coatings, inks, cleaning, and surface preparation.
Despite its performance advantages, naphtha can present concerns related to VOC emissions, flammability, worker exposure, and environmental impact. For industrial formulators evaluating naphtha uses, understanding these tradeoffs can help identify suitable petroleum-based or bio-based solvent options.
VM&P Naphtha: Composition, Flash Point, and Grade
VM&P naphtha is a refined petroleum solvent made primarily from aliphatic hydrocarbons. It is generally lighter and more volatile than mineral spirits, giving it a faster evaporation rate that suits coatings, thinners, cleaning formulations, and other applications requiring quick solvent release.
Exact properties vary according to grade and supplier. VM&P naphtha typically has a relatively low flash point, making flammability an important consideration during formulation, storage, and use. Chemical formulators should review the product’s technical data and safety data sheet for specific boiling range, flash point, composition, and handling requirements before selecting a grade.
Naphtha Uses in Paint, Coating, and Ink Formulations
Common naphtha uses include thinning resins, adjusting viscosity, supporting application properties, and controlling drying time in paints, coatings, varnishes, and inks. VM&P naphtha’s fast evaporation can be useful in formulations that need rapid solvent release after application.
For formulators, suitability depends on resin compatibility, desired evaporation profile, solvency requirements, and application method. These factors can affect flow, leveling, drying behavior, and the finished coating or printed surface. Testing VM&P naphtha in the complete formulation helps determine its effect on both processing and final product performance.
Fast-Drying Cleaning and Surface Prep Applications
Naphtha’s rapid evaporation makes it useful for degreasing, equipment cleaning, and surface preparation before painting or coating. It can remove oils, grease, and other residues while leaving minimal solvent behind, helping surfaces move quickly to the next production step.
For formulators seeking an alternative to conventional naphtha cleaners, the
VertecBio™ Gold product line offers bio-based solvent options developed for industrial cleaning and degreasing applications. Products in this line can support effective soil removal while helping reduce dependence on petroleum-derived solvents. Performance should be evaluated against the specific soils, substrates, drying requirements, and process conditions involved.
Naphtha vs. Mineral Spirits and Xylene: Key Differences
When comparing naphtha vs. mineral spirits, evaporation rate is one of the main distinctions. VM&P naphtha generally evaporates faster, making it useful for quick-drying coatings, cleaning, and surface preparation. Mineral spirits evaporate more slowly and are often selected when longer working time is preferred.
Xylene is an aromatic solvent that offers strong solvency for certain resins, coatings, and industrial soils. However, its health, VOC, and handling considerations can influence solvent selection. Formulators comparing these solvents should consider solvency strength, evaporation rate, resin compatibility, flash point, and regulatory requirements rather than treating them as interchangeable options.
Naphtha's Environmental Footprint and VOC Emissions
VM&P naphtha is petroleum-derived and typically contains volatile organic compounds (VOCs). During application, cleaning, or drying, these compounds can evaporate into the atmosphere and contribute to VOC emissions from industrial operations.
For manufacturers working toward lower-VOC formulations or reduced reliance on petroleum-derived solvents, these characteristics can make traditional naphtha less attractive. VOC content and regulatory status can vary among solvent grades and applications, so formulators should review applicable requirements alongside performance criteria. Bio-based alternatives may provide another route for meeting solvency needs while supporting environmental and formulation goals.
Safety, Storage, and Handling for Naphtha Users
VM&P naphtha is flammable and can create health risks from vapor inhalation, skin contact, or improper handling. Industrial facilities should use suitable ventilation, control ignition sources, wear appropriate personal protective equipment, and follow established procedures for solvent storage and transfer.
Storage requirements depend on the specific grade and applicable regulations. Users should consult the supplier’s safety data sheet (SDS) for exposure controls, incompatibilities, fire protection, spill response, and disposal information. These factors should be considered alongside solvent performance when evaluating naphtha for a formulation or process.
Bio-Based Alternatives for Naphtha Applications
Formulators looking for a naphtha cleaner substitute can evaluate bio-based solvents that provide suitable solvency and evaporation characteristics while reducing reliance on petroleum-derived materials.
The VertecBio™ ELSOL® product line includes bio-based solvent technologies for industrial formulations and cleaning applications.
VertecBio™ ELSOL® TR and
VertecBio™ ELSOL® XR are individual products in this line that may serve as alternatives in applications traditionally using petroleum solvents such as VM&P naphtha.
Selecting a replacement requires testing for solvency, evaporation rate, compatibility, and finished-product performance. Vertec BioSolvents, now part of Shrieve Chemical, can help formulators evaluate ELSOL® TR or ELSOL® XR for their specific application.
How to Test Vertec BioSolvents in Your Formulation
Replacing VM&P naphtha starts with evaluating the alternative under actual formulation and process conditions. Compare factors such as solvency, evaporation rate, substrate compatibility, drying behavior, and finished-product performance against your current solvent.
Vertec BioSolvents, part of Shrieve Chemical, works directly with formulators to identify products suited to specific performance and sustainability targets. Testing a sample can help determine which Vertec solution fits your formulation before moving toward larger-scale adoption.
