Choline Bitartrate Coated is a specialized form of choline salt, carefully engineered to protect the choline core through a unique outer layer. Manufacturers turn to this coated variant to extend shelf life and preserve product integrity during storage and transport. Choline, an essential nutrient, plays a key role in cell membrane health, signaling, and fat metabolism. Coated choline bitartrate arrives as a stable compound, often chosen over uncoated forms because it resists caking, absorbs less moisture from the air, and allows easier mixing into food or feed matrices. The coated surface often feels smooth to the touch, reflecting uniform encapsulation achieved in modern chemical plants.
The composition stands out for its dual layers: the active choline bitartrate core (C9H19NO7) surrounded by a protective coating, typically made from a food-safe or feed-grade material. Physical form can vary between fine powder, small flakes, free-flowing pearls, crystalline solid granules, or re-dispersible beads, depending on the method used for encapsulation during manufacture. This adaptability enables formulation into a wide range of product types — from animal feed pellets to micro-encapsulated nutritional supplements. Choline bitartrate is known for its distinctive bitter taste and faint, grassy aroma, masked by the outer layer. The coated nature prevents premature degradation from humidity, light, and oxygen, giving a substantial edge in terms of stability. Most coated versions present a density in the range of 0.5–0.9 g/cm³, though value may shift based on coating thickness or internal porosity.
As a salt of choline and tartaric acid, choline bitartrate sports a molecular structure featuring quaternary ammonium in choline and the familiar dicarboxylic acid groups of bitartrate. The molecular formula stands at C9H19NO7, with a typical molecular weight of about 253.25 g/mol. Chemists identify the HS Code for choline bitartrate as 2923900090, placing it under “other quaternary ammonium salts and hydroxides.” High-purity grades guarantee choline content not less than 41.1%, with tartaric residue making up the balance. Standard particle size distribution ranges from fine micronized powders under 250 microns to larger beadlets up to two millimeters in diameter — material selection depends on desired application precision, whether quick dissolution in liquid or controlled-release in pelleted formulations.
Choline bitartrate coated enjoys flexible manufacturing options, making possible a breadth of formats. Powdered grades offer rapid dispersal in aqueous solutions, particularly useful for laboratory or beverage applications. Flake and pearl versions provide reduced dust exposure, essential in large-scale automated blending environments. The crystalline solid displays sharp, angular prismatic shapes under magnification, while some formulations yield near-sphere uniformity for smoother distribution in feed mills or supplement plants. Though pure choline bitartrate avoids water, some coated versions can be suspended as stable solutions, extending utility into liquid feed or concentrated nutrient drinks. In most settings, the product remains stable at room temperature, with minimal solubility losses or agglomeration, especially if stored in sealed, moisture-free containers.
Down-to-earth handling is essential with choline bitartrate coated, since its raw chemical nature can irritate eyes, skin, and mucous membranes if mishandled. Standard material safety data sheets classify it as non-hazardous under normal handling, yet recommend avoiding unnecessary exposure through gloves, goggles, and dust masks — an everyday routine on professional manufacturing floors. The coatings commonly employ edible-grade cellulose or food waxes, cutting down dust, bitterness, and accidental inhalation. Uncoated choline bitartrate has a mild hygroscopic tendency, but coatings minimize clumping and extend product lifespan. Bulk shipments rely on robust inner linings for bags or drums to keep the product dry and safe. As a derivative of crude bitartrate and synthetic or plant-based choline sources, the raw materials feed through strict quality controls, ensuring contaminant-free finished products, free of heavy metals, pesticide residues, or microbiological spoilage.
Choline bitartrate coated plays a direct role in supporting animal nutrition, human food fortification, and specialty chemical processes. In animal feeds, it supports optimal growth, brain development, and lean muscle gain, particularly in early-life nutrition for poultry, swine, and young cattle. In powdered or crystalline supplements, it appears in multivitamin blends, ready-to-mix nutrition drinks, or functional food bars. Because of its enhanced process stability, it survives heat processing, moisture shifts, and extended storage — a real challenge for unprotected micronutrients. Some pharmaceutical applications rely on the coated form for taste masking or delayed-release tablet formulations. The product also holds utility in cosmetics and industrial uses where water solubility and compatibility with other materials give a performance edge.
Every user — from food technologist to farmhand — should understand the hazards of concentrated choline bitartrate, especially in its coated variants. Ventilation systems, dedicated transfer equipment, and clear labeling offer basic safeguards. Regulations demand precise traceability from raw material to end product, meeting food or feed safety codes across different regions. Continuous investment in quality assurance, batch testing, and material audit trails builds confidence with downstream users. The coated form, with its lower dust generation and better flow, reduces workplace exposure and the risk of accidental spillage. Recognizing choline’s role as a vital nutrient rather than just a bulk chemical can drive renewed emphasis on safe, responsible handling—an investment that pays off in product quality and consumer trust.
