Pharmaceutical Chemistry
Glycerin 99.7%
Formula:
C₃H₈O₃
GOST/CAS:
CAS 56-81-5 / USP / EP / FCC
Glycerin 99.7% (highly purified, distilled) is a high-grade organic chemical intermediate that meets the strict requirements of international pharmacopoeias (USP, EP). It is a clear, colorless, odorless, viscous, syrupy liquid with a sweet taste and high hygroscopicity. Due to its versatility, safety, and stability, glycerin serves as an indispensable baseline raw material for the pharmaceutical, cosmetic, and food industries.
Applications
Pharmaceutical Formulations: Used as a solvent, humectant, and plasticizer in the production of cough syrups, elixirs, ointments, creams, suppositories, and capsules. It is also an essential component in intravenous and infusion solutions.
Cosmetics & Personal Care: Functions as a key moisturizing and softening agent in creams, lotions, toothpastes, shampoos, and liquid soaps. It effectively protects the skin against dryness by restoring its natural moisture barrier.
Food Industry (E422): Utilized as a thickener, emulsifier, and humectant in confectionery, bakery goods, and alcoholic beverages. It improves product texture, consistency, and extends shelf-life freshness.
Laboratory Research & Biotechnology: Acts as a cryoprotectant for the freezing and long-term storage of biological samples (cell cultures, enzymes, DNA), and serves as a mounting medium in microscopy.
Key Advantages
Maximum Purity (99.7%+): Full compliance with stringent USP/EP standards guarantees the absence of harmful impurities, heavy metals, diethylene glycol, and ethylene glycol.
High Biocompatibility: As a natural metabolite of the human body, it is completely safe (GRAS standard), non-toxic, and does not cause irritation to the skin or mucous membranes.
Excellent Technical Properties: Features superior miscibility with water and alcohol, high hygroscopicity, and the ability to stabilize emulsions, preventing final products from drying out.
GMP Standards & Stability: Manufactured at facilities with certified quality management systems, ensuring strict adherence to physical and chemical parameters from batch to batch.
Storage & Transportation
- Store in dry, cool, well-ventilated warehouses in tightly sealed original packaging.
- The product is highly hygroscopic, making it crucial to prevent exposure to atmospheric moisture and direct sunlight.
- Recommended storage temperature: +15°C to +25°C. Viscosity may increase when stored at lower temperatures.
- Transportation is permitted by all types of covered transport vehicles, provided container airtightness is maintained. The material is classified as non-hazardous cargo. Shelf life — 2 years.
