Product Overview
Ergosterol Powder is a fungal sterol raw material commonly reviewed as a vitamin D2 precursor, sterol intermediate, and research or formulation ingredient. It is usually supplied as white to light yellow crystalline powder with >=98% or agreed assay specification, and buyers often review assay method, source route, melting point, residual solvents, appearance, packaging, and document scope before technical or commercial evaluation. It is commonly considered for vitamin D2 precursor projects, sterol intermediate use, nutraceutical and food fortification development, cosmetic concepts, and research applications, with sample support and batch documents available for sourcing reference.
Applications
Vitamin D2 Precursor Projects
Ergosterol powder is commonly reviewed as a precursor material for vitamin D2-related production or development projects. Buyers should confirm assay, source route, impurity profile, residual solvents, and processing suitability before sample or bulk order confirmation.
Sterol Intermediate Use
For sterol intermediate and biochemical raw material projects, ergosterol can be selected when a defined fungal sterol compound is required. Purity, melting point, related substances, and batch consistency should be reviewed during technical evaluation.
Nutraceutical and Food Fortification Development
Ergosterol may be considered in nutraceutical or food fortification development where vitamin D2-related sourcing, plant-based positioning, or non-animal sterol route is relevant. Final suitability should be confirmed according to processing route, regulatory market, and formulation design.
Cosmetic and Research Applications
Ergosterol can be reviewed for cosmetic concept development, sterol-related research, and fungal biology or analytical projects. Buyers should confirm permitted use, formulation compatibility, and documentation requirements before purchase.
How to Choose the Right Grade / Form
For vitamin D2 precursor projects
Recommended direction: >=98% ergosterol powder
Why: High assay and controlled impurity profile are important when ergosterol is used as a precursor or intermediate material.
For research and analytical use
Recommended direction: assay and identification confirmed by COA
Why: Research projects usually require clear identity, assay method, melting point, and document traceability.
For nutraceutical or food development
Recommended direction: specification matched to destination-market review
Why: Buyers should confirm source, residual solvents, heavy metals, microbiology where applicable, and regulatory suitability before commercial use.
For cosmetic formulation concepts
Recommended direction: cosmetic-compatible specification review
Why: Cosmetic projects should review purity, color, odor, solubility behavior, stability, and compatibility with the final formulation system.
Confirm assay method
Ergosterol powder is commonly reviewed by HPLC assay, such as >=98% or agreed specification. Buyers should confirm the test method and COA format before comparing quotations.
Confirm source route
Ergosterol may be sourced from yeast, mushroom, fungal, or other agreed non-animal routes. Source route can affect buyer positioning, documentation, and destination-market requirements.
Confirm application requirements
Vitamin D2 precursor projects, research use, food fortification development, cosmetic concepts, and intermediate applications may require different QC limits and document packages. The intended use should be confirmed before quotation.
Technical & Formulation Notes
Technical Notes
Ergosterol powder is mainly evaluated by assay, identity, appearance, melting point, source route, residual solvents, loss on drying, heavy metals, and batch consistency. Buyers should confirm whether the project requires high-purity sterol raw material, vitamin D2 precursor use, research grade, or buyer-defined specification before comparing quotations.
Manufacturing & Process
Ergosterol is commonly obtained from fungal, yeast, mushroom, or related non-animal source routes followed by extraction, purification, drying, milling, and sieving according to target specification. Process control focuses on assay, impurity profile, residual solvent control, color, moisture, melting range, particle behavior, and batch-to-batch consistency.
Compatibility / Formulation Notes
For vitamin D2 precursor projects, ergosterol should be evaluated for assay, impurity profile, residual solvents, source route, and processing suitability.
For sterol intermediate use, melting point, particle behavior, loss on drying, and batch consistency should be reviewed before scale-up or process evaluation.
For nutraceutical and food development, buyers should confirm regulatory suitability, residual solvent limits, heavy metals, microbial limits where applicable, and final formulation compatibility.
For cosmetic systems, solubility behavior, color, odor, oil-phase compatibility, heat exposure, and stability should be tested in the final formula.
During storage and handling, ergosterol powder should be protected from moisture, heat, strong light, oxidation, contamination risk, and prolonged open-air exposure.
Extended QC & Test Items
Common review items include appearance, identification, assay, melting point, loss on drying, residue on ignition, heavy metals, residual solvents, microbial limits where applicable, and batch documentation. Additional tests can be discussed according to intended use, destination market, and buyer specification requirements.
