Acid Purified Light Alkanes (Petroleum Hydrocarbons, Light Paraffinic)

Acid purified light alkanes (CAS 64742-14-9) is a hydrotreated paraffinic petroleum fraction used as a secondary carrier solvent in car care formulas. The acid purification process removes aromatic and polar impurities, producing a cleaner, lower-odor petroleum cut than standard naphtha.

At 1–5% concentrations in consumer polishes, this ingredient contributes modestly to VOC content and provides a light carrier medium that helps spread the product and evaporate cleanly after application. Toxicologically it is mineral-oil-adjacent — low acute hazard, with skin defatting as the primary concern for prolonged or repeated contact.

Not aquatically toxic at product dilution levels. Biodegrades slowly (longer-chain alkanes degrade faster than short-chain aromatics but slower than oxygen-containing solvents).
