White oils are highly refined mineral oils that consist of saturated aliphatic and alicyclic nonpolar hydrocarbons. They are hydrophobic, colorless, tasteless, odorless, and do not change color over time. As a leading white mineral oil supplier to multiple industries, our white oils are chemically and biologically stable, non-comedogenic, and do not support pathogenic bacterial growth. These properties make white oils the standard in many industries.
White oils make an ideal blending base for personal care and pharmaceutical products. Their inert nature makes them easy to use, as they lubricate, smooth, soften, extend and resist moisture in many formulations. You can find our USP and NF grade white oils in products ranging from baby oils and lotions to sunscreens, tissues and antibiotics. The plastics industry uses our Hydrobrite line of low-volatility white oils in the production of plastics such as polystyrene, polyolefins, thermoplastic elastomers, and various other polymers to improve and control the melt flow rate of the finished polymer to provide release properties, or change the physical characteristics.
Our food grade mineral oils have proven themselves in food applications as wide ranging as dough divider and pan oils to dust suppression in grain silos. They lubricate food-handling equipment, impregnate wrapping paper to keep foods crisp, control foam in beet sugar and vinegar production, and enhance the leather tanning process. As one of the leading hot melt adhesive manufacturers, our low pour-point naphthenic grades improve hot melt adhesives and lubricate air conditioner and refrigerator compressors.
Sonneborn supplies USP, NF, and technical white oil grades and will custom-blend to meet customer specifications. USP and NF grades meet FDA 21 CFR 172.878 and 21 CFR 178.3620(a) regulations for direct food contact, and USDA H1 food processing lubricant standards. Our USP mineral oil grades have viscosities that range from 35cSt to 420cSt, and pour points that range from -10°C to less than -35°C for our naphthenic grades. Our NF light food grade mineral oils have lower viscosities, ranging from 7cSt to 30cSt, and pour points as low as -25°C for our 40 oil grain dust suppressor.
