Shandong Tianli Pharmaceutical Co., Ltd Vitamin C: Physical Characteristics and Product Details

What is Vitamin C from Shandong Tianli Pharmaceutical?

Vitamin C delivered by Shandong Tianli Pharmaceutical Co., Ltd defines the substance known chemically as ascorbic acid. With a molecular formula of C6H8O6 and a molar mass near 176.12 g/mol, the white substance appears as powder, crystalline solid, or occasionally fine flakes. The appearance tends to shift from bright white to light yellow, depending on purity and particle size. This essential ingredient plays an important role as an antioxidant and supports vital physiological processes in both human and animal nutrition. Talking about raw material quality, Shandong Tianli employs strict control over procurement, so each batch holds a well-defined assay, minimal impurity traces, and stable shelf life, something that end users often look for in food additives, fortification, and supplement manufacturing.

Product Structure and Specifications

Each crystal of ascorbic acid reveals a six-carbon backbone, naturally inclined to form monoclinic crystals. The dry-density averages about 1.65 g/cm³ at room temperature, giving just enough mass for uniform dispersion in wet and dry solutions. Vitamin C from Shandong Tianli usually comes as loose powder, but other forms such as granular, pearlized, and flake cuts serve distinct application needs. The product melts near 190–192˚C. Water solubility remains high, with saturation in cold water leading to fully transparent solutions. Specific rotary power of the product, ranging from +20.5° to +21.5° (20°C in water), demonstrates purity and structural conformity. These specification checkpoints frame product integrity, which almost every user checks for in high-value vitamin C—especially when mixing in pharmaceuticals or fortified foods for infants.

Molecular Features and Chemical Properties

The ascorbic acid molecule houses multiple hydroxyl groups that can donate hydrogen, acting promptly to neutralize free radicals. Acidic character shines through with a pKa of 4.2, which allows it to function as a reducing agent. That’s why vitamin C features prominently in pharmaceutical, food, and feed material lists. White, almost odorless, and slightly tart to the taste, the chemical maintains stability under dry, cool conditions—directly affecting shelf life and practical handling. The melting point and loss on drying remain critical for factories, as these influence blending and stability in different formulations. Wet-process and fermentation techniques define the nature of the finished product, giving flexibility in downstream processes. Each batch runs through several spectroscopic and chromatographic tests to confirm these characteristics before shipping.

Physical Appearance: Flakes, Crystals, Powder, and Solutions

Shandong Tianli Vitamin C stands out most commonly in powder or crystalline form, both of which offer advantages. Fine powder dissolves rapidly in water, leaving a clear to slightly opalescent solution depending on concentration and solvents used. Crystals and flakes provide advantages in direct tablet pressing or as a visible fortification in food. The powder type flows free, thanks to precise drying and milling steps. Typical bulk density averages between 0.5–0.7 g/ml for powder, 0.8–1.2 g/ml for flakes or crystals, which directly impacts storage, transport, and blending steps for manufacturers. Samples do not clump readily, due to stringent moisture control. For food and pharmaceutical applications, each variant minimizes dust and airborne particles, which increases safety on the production line. Most industrial or laboratory users request the product in high-concentration solutions, especially for injection-grade or beverage fortification; the prepared solutions display near-complete transparency, unchanged odor, and stable pH over reasonable storage time.

HS Code, Safety, and Hazard Considerations

From the standpoint of cross-border trade and regulatory control, Shandong Tianli’s Vitamin C presents under HS Code 29362700—a designation aligned with ascorbic acid and its salts. Product safety draws attention in both production and end use. Safety instructions stress storage in cool, dry, well-ventilated areas, away from direct sunlight and sources of contamination. With an acute oral LD50 reported in rats at around 11,900 mg/kg, the risk of toxicity at typical exposure remains extremely low, supporting claims for safety in food-grade and pharmaceutical operations. Skin or eye contact may trigger mild irritation if product mishandling occurs—protective gloves and eyewash stations always sit close by during bulk handling in plants I have visited. Although not classified as hazardous under GHS standards, facilities always keep local chemical hazard sheets on hand, and regular staff training focuses attention on correct bag opening, weighing, and finished product transfer.

Raw Material Sourcing and Material Safety

The raw material chain starts with glucose sourced from non-GMO corn, treated and fermented using specialized microorganisms. Repeated purification ensures ascorbic acid comes out without solvent residues or microbial threats, with the final inspection establishing microbial counts far below industry limits. Every batch features an attached certificate showing assay, heavy metal levels, arsenic, lead, and less-common contaminants—something I have seen buyers carefully check, especially for applications in infant and medical nutrition. Packaging integrity forms the last leg of the safety protocol; multi-layered bags and nitrogen-flushed drums prevent oxidative loss and contamination during global transport. No synthetic dyes, preservatives, or unknown excipients—traceability starts at the glucose farm and runs through each tank, mill, and drying oven until shipment leaves the facility with a final QC stamp.

Practical Uses and Industry Outlook

Shandong Tianli Pharmaceutical’s Vitamin C flows into food fortification, dietary supplements, animal feed, cosmetics, and pharmaceutical APIs. Food producers keep close tabs on purity, especially given demand for non-GMO and allergen-free status in American and European markets. Beverage makers add it to everything from juices to functional waters, relying on stability under acidic and pasteurized conditions—a fact that shapes their formulations. Nutraceutical firms mix the material for tablets or capsules, depending on both solubility and compressibility. Feed-grade material winds up in powdered premixes or direct sprinkling in industrial-scale blending lines, supporting growth in pigs, poultry, and aquaculture. Chinese-made ascorbic acid—especially from Shandong Tianli—commands confidence across continents for consistent assay, low impurity profile, and prompt technical support during new product development or trouble-shooting. As new uses arise—such as antioxidant preservation in natural beauty products, or as stabilizers in food oils and ready-to-eat snacks—the role held by quality, traceable vitamin C only grows larger, reflecting the importance of physical purity, hands-on transparency, and strict material science.
