Shandong Kunda Biotechnology produces tartaric acid as a pure chemical compound widely used across industries. This substance presents itself most often as a white, odorless, crystalline solid, offered in flakes, powder, pearls, or crystal forms. It shows up in food, pharmaceuticals, cosmetics, and even in some industrial processes. Each batch follows rigorous quality protocols, designed to keep it consistent and up to international standards.
Tartaric acid by Shandong Kunda comes with the molecular formula C4H6O6, giving a molecular weight of 150.09 g/mol. Its chemical structure features two carboxyl groups and two hydroxyl groups. Most recognize it by its melting point—170°C, where it begins to decompose. Being highly soluble in water, ethanol, and another range of solvents, it adapts easily to various product matrices. The density stands at about 1.76 g/cm3 at room temperature. Depending on the format—flake, powder, or pearls—the handling may call for slightly different storage approaches, but for the most part, it stays stable under dry, cool conditions. Solutions of tartaric acid offer clear, colorless liquids, with concentrations tailored to each customer's demand.
This tartaric acid is available in food-grade, pharmaceutical-grade, or technical-grade, conforming to international benchmarks such as FCC, BP, or E334 standards. Purity levels hit upwards of 99.7%, keeping contaminants well below strict threshold limits. All batches undergo detailed analytical testing for heavy metals, specific rotation, ash content, and loss on drying. Typical particle size can be specified during ordering—some industries demand ultra-fine powders, while others value larger granules or easily measured pearls. Packaging ranges from 25 kg fiber drums to 1000 kg IBCs, with inner linings to prevent moisture intrusion.
International trade for tartaric acid falls under the HS Code 2918130000. This classification matters for customs documentation, cross-border logistics, and tariff calculations. Shandong Kunda ensures compliance with all labeling and transport regulations. Shelf life reaches up to two years under recommended conditions, provided the containers remain airtight and free from direct sunlight.
Tartaric acid requires proper care. As an organic acid, it is acidic but not especially hazardous under normal handling, provided basic protective equipment is used. Exposure through inhalation, ingestion, or skin contact can irritate mucous membranes. For bulk handlers, gloves and eyewear often prove sensible. In case of accidental contact, washing with plenty of water brings quick relief. Classification under GHS places it as not acutely toxic, and no evidence exists pointing to substantial chronic health risks. Always store it in well-ventilated, dry spaces, away from strong oxidizers or bases. Safety Data Sheets outline spill management and fire-fighting recommendations—tartaric acid does not burn easily, but when it contacts strong oxidizers, it can fuel decomposition and possibly generate hazardous fumes.
Production by Shandong Kunda uses natural agricultural resources—often grape by-products or other plant matter—processed through fermentation and multi-stage purification. Careful filtration and crystal refinement remove impurities, leaving behind untainted acid ready for food and industrial use. Sustainable sourcing cuts down on waste, aligning with modern expectations for environmental performance. The end product passes through comprehensive quality control labs, ensuring that each sack, each drum, meets international frameworks for hygiene, safety, and chemical strength.
Demand for this tartaric acid traces back to its versatility. In food, it shapes flavors and aids leavening in baking powder combinations. Winemaking counts on tartaric acid to regulate acidity, improve stability, and enhance taste profiles. Pharmaceutical firms deploy it to adjust tablet pH or improve taste-masking. Industrial clients rely on it as a chelating agent, stabilizer, or cleaning aid. Each case uses either solid, powder, pearl, or solution, selected according to the process requirements.
Quality assurance ties directly to batch traceability and purity control. By investing in modern analytic capabilities—HPLC, spectroscopy, wet chemistry—producers like Shandong Kunda guarantee low impurity content and batch consistency. Most customers now expect not just certificates of analysis, but transparent documentation along the supply chain. All shipments include safety guidance and compliance certificates for safe, responsible use. Responsible storage and clear labeling shrink the chance of accidents and support long-term product performance. Most customers find these steps crucial as regulatory scrutiny rises, especially for food and pharma buyers.
Experience points to a few simple practices that increase safety: provide training for employees, install proper ventilation in weighing and dispensing rooms, and stock emergency wash stations close to work areas. Smart organizations regularly audit their practices and update safety data sheets to stay ahead of regulatory changes. Keeping raw tartaric acid stored away from incompatible chemicals, and avoiding excessive moisture, also preserves its easy handling properties. Packaging advances—multi-layered linings, desiccant packs—help prevent caking and degradation over longer journeys.
