Physicochemical Properties & Stability

Understanding the physical and chemical characteristics of raw materials is critical for optimal formulation.

  • Solubility: D-Biotin is sparingly soluble in water and ethanol but highly soluble in dilute alkaline solutions.
  • Stability: The powder exhibits excellent stability to heat, light, and atmospheric oxygen in neutral and acidic environments. However, formulators should note that it can undergo degradation in strong alkaline conditions.
  • Melting Point: 231-233°C, ensuring stability during standard manufacturing and pelleting processes.

Biological Functions & Mechanisms of Action

As a crucial coenzyme for carboxylases, D-Biotin plays an indispensable role in intermediate metabolism. Its biological functions encompass:

  1. Energy Metabolism: Acts as a coenzyme in the metabolism of carbohydrates, lipids, and proteins, facilitating the conversion of macronutrients into glucose and subsequent cellular energy (ATP).
  2. Lipid & Protein Synthesis: Essential for lipogenesis and the synthesis of fatty acids. It also participates in protein metabolism, including the transfer and decarboxylation of various amino acids, and supports urea synthesis and excretion.
  3. Carbohydrate Metabolism & Glycemic Control: Involved in gluconeogenesis and helps improve the regulation of blood sugar levels, thereby promoting cellular health and regeneration.
  4. Keratin Infrastructure: Crucial for maintaining the structural integrity of skin, hair, and mucous membranes by supporting the production of keratin.
  5. Methyl Transfer: Participates in vital metabolic processes as a coenzyme component, including methyl transfer reactions.

Industrial Applications & Formulation Compatibility

Extract Warehouse supplies bulk D-Biotin Powder tailored for diverse industry applications. Our product demonstrates excellent compatibility with various formulation matrices.

Dietary Supplements & Pharmaceuticals

  • Nutraceuticals: Widely used in hair, skin, and nail supplements, as well as comprehensive B-complex and multivitamin formulations.
  • Pharmaceuticals: Formulated into tablets, capsules, and oral solutions as an adjuvant for treating biotin deficiency, metabolic disorders, and malnutrition.
  • Biochemical & Laboratory Applications: Due to its strong binding affinity with avidin/streptavidin, pure biotin powder is extensively used as a marker in bioassays for proteins, antigens, antibodies, and nucleic acids (DNA, RNA).

Food & Beverage Industry (1% Food Grade)

  • Used as a vital nutritional fortificant in infant formulas, nutritional shakes, energy bars, and fortified beverages to meet daily recommended dietary allowances (RDA).

Personal Care & Cosmetics
