Product Overview
A-A-59601E Type III ACS Grade is a grade-specific petroleum distillate classified within the Stoddard solvent family. It ships as a clear, colorless liquid with a mild hydrocarbon odor — the kind of solvent that cleans without leaving a residue or fighting you on evaporation rate. This product carries its listed grade designation; confirm the lot-specific COA against your requirements.
This product serves parts-cleaning operations, surface preparation lines, and laboratory extraction work where the solvent itself cannot introduce unknowns. we distribute it in our Taylor, TX warehouse in sizes from 1-quart bottles through 330-gallon totes, and we ship it as DOT-regulated hazmat every business day.
Why This Grade
ACS Grade is the dividing line between a commodity shop solvent and one that belongs in an analytical or quality-critical workflow. A general-purpose mineral spirits will degrease a part just fine — but if you then need to run a residue analysis, an IR scan, or a gravimetric test on what you cleaned, you need a solvent whose impurity profile is controlled and documented. That is what ACS Grade delivers.
For buyers running parts-washing stations, coating prep lines, or print shops where residue specs are looser, a technical-grade mineral spirits does the job at lower cost. Choose ACS Grade when your process has an analytical step downstream, when your customer spec calls it out by name, or when the federal A-A-59601E Type III specification is written into your contract.
Chemical Profile
A-A-59601E Type III ACS Grade is a hydrocarbon mixture (CAS 64742-47-8) — not a single compound, so its molecular weight varies across the distillation cut. It presents as a clear, colorless liquid with a mild petroleum odor. Density runs approximately 0.79 g/mL at 15 °C, and vapor pressure stays below 1 mmHg at 20 °C, which means it evaporates slowly enough to give you working time on a surface but will flash off under moderate heat. It is insoluble in water, so it separates cleanly in aqueous wash systems and does not carry over into water-based rinse stages.
Industrial Applications
A-A-59601E Type III sees daily use across several industries where a controlled-purity hydrocarbon solvent is required.
-
Parts Cleaning and Degreasing — Dissolves petroleum-based greases, cutting oils, and shop soils from machined parts, tooling, and assemblies. The low vapor pressure gives operators adequate soak and wipe time before the solvent evaporates, and the ACS Grade purity means the cleaned surface is free of solvent-contributed contaminants — important ahead of coating, bonding, or inspection steps.
-
Surface Preparation — Used as a final wipe solvent before painting, powder coating, or adhesive bonding in aerospace, defense, and general manufacturing. The A-A-59601E specification is frequently called out in military and federal maintenance procedures for exactly this purpose.
-
Laboratory Extraction Solvent — ACS Grade purity makes this product suitable as an extraction medium in gravimetric oil-and-grease analyses and similar wet-chemistry methods where the solvent must not contribute detectable residue to the result.
-
Chemical Intermediate — Serves as a carrier solvent or reaction medium in formulation and blending operations where a narrow-cut, low-odor hydrocarbon fraction is specified.
-
Printing and Ink Cleanup — Cleans ink from rollers, blankets, and press components in offset and letterpress operations. The controlled evaporation rate prevents premature drying on the press while still allowing a clean wipe-down.
Handling & Storage
This product carries a Danger signal word (per the product's GHS classification). The three hazard statements you need to manage are: H304 — may be fatal if swallowed and enters airways; H336 — may cause drowsiness or dizziness; and H227 — combustible liquid (per the product's GHS classification). The aspiration hazard (H304) is the most acute risk — ingestion or vomiting scenarios can pull liquid into the lungs.
Wear chemical-splash goggles, nitrile or compatible chemical-resistant gloves, and use in a well-ventilated area or under local exhaust. If vapor concentrations build in an enclosed space, respiratory protection rated for organic vapors is necessary.
Store in a cool, dry area away from direct sunlight, ignition sources, and strong oxidizing agents. Compatible container materials include HDPE and glass. Keep containers tightly closed when not in use to minimize vapor accumulation and slow evaporation losses. Ensure your storage area has adequate ventilation — vapor is heavier than air and will settle in low points.
Hazmat & Shipping
Canonical transport status is not regulated. Review the current SDS and carrier requirements before shipment.
Documentation
A Safety Data Sheet ships with every order, available in English, Spanish, French, and Japanese. A lot-specific Certificate of Analysis is available on request, documenting the purity and composition of the specific production lot you receive. A Technical Data Sheet is also available for detailed product specifications. If you need documentation ahead of your purchase — for EHS review or incoming-material approval — contact us and we will send it over.
