Frequently Asked Questions

What grades of glycerin are available for industrial and food-grade applications in Texas?▾

Chemical & Filtration Products of Texas supplies glycerin in Industrial-grade, USP-grade, and FCC Food Grade formulations. USP-grade glycerin meets United States Pharmacopeia standards for pharmaceutical, personal care, and nutraceutical applications. FCC Food Grade glycerin meets Food Chemicals Codex standards for direct food use — including as a humectant, sweetener, and solvent in food and beverage products. Industrial-grade glycerin is used in antifreeze formulations, chemical synthesis, and manufacturing. Every order ships with SDS documentation and lot traceability. Contact us at 855-TEX-CHEM for current pricing.

What is the difference between USP glycerin and FCC Food Grade glycerin?▾

USP glycerin meets the purity standards of the United States Pharmacopeia and is the specification required for pharmaceutical manufacturing, personal care products, and topical applications. FCC Food Grade glycerin meets the Food Chemicals Codex standard required for direct use in food and beverage formulations. In practice, many glycerin products meet both standards simultaneously — the relevant specification depends on your application's regulatory requirements. We supply both with full grade certification and lot traceability. Contact us at 855-TEX-CHEM to confirm the right grade for your process.

Can I source bulk glycerin in Texas for food and beverage production?▾

Yes. We supply FCC Food Grade glycerin in quantities from single drums through bulk deliveries to food and beverage manufacturers across Texas, including Houston, Dallas-Fort Worth, San Antonio, and Austin. Each shipment includes full lot traceability and SDS documentation to support your food safety program and compliance audits. Contact us at [email protected] or 855-TEX-CHEM to request pricing for your required volume.

What is glycerin used for in industrial manufacturing?▾

Glycerin has a broad range of industrial applications including use as a humectant in personal care and food products, as a plasticizer in pharmaceutical tablet coatings, as a base for antifreeze formulations, as a feedstock for chemical synthesis (including propylene glycol and polyols), and as a raw material in the production of resins and explosives. Refined glycerin is also a co-product of biodiesel production. We supply glycerin to manufacturers, blenders, and formulators across Texas with full documentation. Contact us at 855-TEX-CHEM.

What is glycerin's role in the biodiesel industry?▾

Glycerin (glycerol) is the primary co-product of the transesterification process used in biodiesel production — approximately 10 pounds of crude glycerin is produced for every 100 pounds of biodiesel. This crude glycerin must be refined to reach industrial, USP, or FCC Food Grade quality for resale into other markets. We work with biodiesel producers and chemical refiners and can discuss supply and sourcing arrangements. Contact us at 855-TEX-CHEM to discuss your glycerin requirements.

Does glycerin require special handling or storage conditions?▾

Glycerin is a non-flammable, non-toxic, hygroscopic liquid that absorbs moisture from the air. Storage containers should be kept tightly sealed to prevent moisture absorption and contamination. USP and FCC Food Grade glycerin must be stored away from materials that could cause contamination, including non-food-grade chemicals. Chemical & Filtration Products of Texas provides a current SDS with every shipment documenting proper storage, handling, and safety requirements. Contact us at 855-TEX-CHEM for guidance.
