CAS 56-81-5Pharmacopoeia grade
USP Glycerin
Water-white glycerol exceeding 99% assay with minimal MONG and moisture, released against USP/NF, EP or BP monographs for cosmetics, personal care and pharmaceutical formulations.
What Is USP Glycerin?
USP glycerin is refined glycerol meeting United States Pharmacopeia (USP/NF) or equivalent European (EP) and British (BP) monographs. It is colourless, transparent and virtually odourless, the benchmark for regulated personal care, OTC pharma and high-purity chemical synthesis.
Upstream production mirrors other glycerin grades: biodiesel transesterification or oleochemical splitting, followed by concentration and vacuum distillation. Additional polishing, ion exchange, activated carbon and microfiltration, achieves compendial chloride, sulphate and heavy-metal ceilings.

Typical USP glycerin specification
Compendial targets; acceptance per supplier CoA.
| Parameter | Typical | Limit | Method |
|---|---|---|---|
| Glycerol content | ≥ 99.0–99.7% | USP/EP typical | EN 14199 |
| Water | < 0.5% | per monograph | Karl Fischer |
| Colour (APHA) | ≤ 10 | water-white | ASTM D1209 |
| Chlorides | < 10 ppm | tighter on request | USP |
| MONG | < 0.5% | n/a | residue |
| CAS | 56-81-5 | n/a |
Regulatory positioning
- USP glycerin meets pharmacopoeia limits, not assumed from technical grade CoA.
- Food use may additionally require E422 food-additive compliance pack.
- Not a direct HVO lipid feedstock; chemical identity CAS 56-81-5 across all grades.
Applications
- Personal care. Humectant in creams, serums, toothpaste and oral care.
- Pharma. Excipient in syrups, capsules and topical dosage forms.
- Food E422. Upgrade path to food additive grade with E-number documentation.
- Medical devices. Formulation component where biocompatibility testing applies.
Frequently Asked Questions
What is USP glycerin?
Pharmacopoeia-grade glycerol min. 99% for cosmetics, pharma and personal care, stricter than technical grade on MONG, colour and ion limits.
USP vs technical glycerin?
USP exceeds 99%, water-white, compendial release. Technical is 90–99.5% with greyish tone and higher MONG, lower cost for industrial chemistry.
Which monographs?
USP/NF, EP, BP and IP variants aligned to your QA specification.
Packaging?
ISO, IBC, 250 kg drums with heated transport option in cold climates.
Kosher and Halal?
Available on request with supplier certificates for downstream certification.
Price quote?
Send monograph, volume and destination to sales@suatfuels.com.
What is the HS code for glycerin?
29054500 (glycerol) is commonly used for refined glycerin in international trade; confirm with your customs broker for formulation-specific codes.
What does the USP glycerin monograph require?
Minimum glycerol content, limits on water, chlorides, sulphates, heavy metals and MONG per USP/NF; Suat Fuels maps CoA to your specified monograph.
What should a pharmaceutical glycerin CoA include?
Batch identity, glycerol assay, impurity panel, appearance, density/refractive index where applicable, and compendial conformance statement.
