Food grade glycerin 99.5% (CAS 56‑81‑5) supplied by Global Optimals is a high‑purity, color‑less liquid that meets FCC and USP specifications. Glycerin is a trihydroxy polyol derived from the hydrolysis of fats and oils, which explains its strong affinity for water and its ability to form extensive hydrogen‑bonded networks. This molecular structure makes glycerin an excellent humectant, preserving moisture in dry mixes, confectionery glazes, and pharmaceutical syrups, thereby extending shelf life. In the confectionery sector glycerin is frequently used as a plasticizer in chewing gums, where it softens the texture and prevents sugar crystallization, and in bakery applications it contributes to crumb softness and prolongs freshness of breads and cakes. When combined with polysaccharide coatings such as gelatin or agar‑agar, glycerin improves flexibility and elasticity of the film, a valuable property for candy shells and edible coatings. In non‑alcoholic beverage formulation glycerin serves as a solvent for flavor oils and sweeteners, enabling uniform distribution of aroma compounds without the need for ethanol. In cosmetics it is often paired with plant oils (jojoba, almond) and emulsifiers (cetyl alcohol, polysorbate 80) to create stable creams and lotions that deliver long‑lasting hydration. In pharmaceutical manufacturing glycerin appears in capsules, topical ointments, and injectable solutions; its low toxicity and neutral pH effect allow it to be compatible with a wide range of active ingredients. The viscosity of about 1 800 cP at 20 °C provides predictable rheology, facilitating precise control of mixing speed and shear forces during production. For storage, sealed stainless‑steel or corrosion‑resistant polymer containers kept at 5‑25 °C, away from direct sunlight and heat sources, are recommended to maintain product integrity. Although glycerin is classified as a non‑hazardous material, transport should follow Class 9 dangerous‑goods guidelines to prevent accidental spills. When an ultra‑pure fraction is required—for high‑precision pharmaceutical or cosmetic formulas—the material can be filtered through 0.2 µm membrane filters, yielding a clear, particle‑free glycerin suitable for sensitive applications.

Food‑grade glycerin 99.5% should be stored in a dry, well‑ventilated area, protected from direct sunlight and heat sources. Recommended storage temperature is between +5 °C and +25 °C; higher temperatures may increase evaporation and alter viscosity. Shelf life is typically 24 months when the packaging remains intact. Use protective gloves and safety glasses during handling, avoiding skin and eye contact. Ensure the polyethylene or glass container is tightly sealed and free of damage to prevent contamination and moisture loss.
