Light specialty hydrocarbons from Sonneborn are highly refined solvents with high flash points. They are made by fractionating each grade to a narrow boiling range, then catalytically hydrotreating to remove all aromatic and other unsaturated hydrocarbons. The resulting distillate resembles a very light white oil that is used in numerous and diverse applications.
Like white oils, light specialty hydrocarbon grades are hydrophobic, colorless, tasteless, virtually odorless and color-fast. Chemically and biologically stable, they are non-comedogenic and do not support pathogenic bacterial growth.
Light specialty hydrocarbons from Sonneborn are direct substitutes for high-VOC solvents in personal care, consumer and institutional products. They lower the VOCs in such aerosol systems as air fresheners, furniture polishes and insecticides. Non-aerosol uses include: waterless hand soaps; body lotions and creams; floor polishes; nail polish removers; charcoal lighter fluids; and liquid candles.
Light specialty hydrocarbons also have many industrial uses. Applications include: defoaming agents; metal foil; sheet rolling and quench oils; vegetable froth flotation; dust control agents; and the manufacture of paper and board.
PD-23 and PD-28
PD-23 is the lightest specialty hydrocarbon product. It has excellent solvency and a flash point of 230°F (ASTM D-92). The flash point of PD-28 is still higher at 270°F.
These two grades are not classified as combustible under DOT regulations. Neither the International Agency Research on Cancer (IARC), the National Toxicology Program (NTP), nor OSHA lists them as carcinogenic. PD-23 complies with FDA 21 CFR 172.884 and 21 CFR 178.3650 food regulations. PD-28 complies with FDA 21 CFR 172.878 and 21 CFR 178.3620(a) regulations for direct food contact.
PD-23 and PD-28 meet the low vapor pressure-volatile organic compounds (LVP-VOC) exemption criteria under the California Air Resource Board (CARB) Method 310. As such, Sonneborn light hydrocarbons may be considered non-reportable VOCs in calculations of the VOC contents of regulated consumer product categories in the California Consumer Product Regulations.
