Myo-Inositol Powder: Sourcing, Specifications & Manufacturing Guide for B2B Buyers
1. What is Myo‑Inositol?
Myo‑Inositol (also written inositol, cyclohexanehexol) is a naturally occurring carbocyclic sugar present in plants, fruits and grains. Chemical identifiers: CAS 87‑89‑8; empirical formula C6H12O6. In commercial supply it is offered as a crystalline or powdered form suitable for industrial formulation.
Chemical properties (summary): polyol with six hydroxyl groups; highly water‑soluble; hygroscopic in certain handling conditions. Typical appearance in supply: off‑white to white fine powder or crystalline granules.
2. Powder form & manufacturing
Commercial Myo‑Inositol is commonly supplied as a spray‑dried powder or micronised crystalline powder, manufactured to provide consistent handling and blending performance. Standardisation is done to guarantee purity and to provide lot‑specific analytical documentation.
- Typical purity: ≥99% (assay by HPLC or equivalent validated method; COA per lot).
- Manufacturing form: spray‑dried powder or micronised crystals, free‑flowing when correctly packed and stored.
- Particle size considerations: formulation compatibility depends on particle size — common targets are >95% through 60 mesh for capsule/tablet filling and finer grades (e.g. >95% through 200 mesh) for premixes and instant beverage blends. Specify particle‑size distribution in your technical brief if flow or dissolution behaviour is critical.
- Moisture control: material should be handled and stored under low‑humidity conditions to avoid caking; anti‑caking agents are not typical unless requested.
3. Industrial applications
Myo‑Inositol supplied as a high‑purity powder is a raw‑material ingredient for manufacturers. Common manufacturing and formulation uses include:
- Ingredient for finished‑product supplement manufacturers (as a powdered raw material).
- Inclusion in functional‑food formulations and nutraceutical blends where a water‑soluble powdered ingredient is required.
- Use in beverage premixes and instant powders where solubility and particle size affect processing and mouthfeel.
- Technical compatibility: suitable for dry blending, encapsulation, tableting and premix lines. Confirm excipient and process compatibility in your formulation trials.
4. Quality & compliance checklist
When sourcing Myo‑Inositol for commercial manufacture, request the following documentation and test results for each lot:
- Certificate of Analysis (COA) with lot number and issue date, reporting identity, assay (purity), moisture, loss on drying, residual solvents (if any), and particle‑size distribution where relevant.
- Impurity profile and limits (related substances) by validated chromatography method.
- Heavy metals panel (Pb, As, Cd, Hg) with acceptance limits referenced on the COA.
- Microbiology — total plate count and absence/limits for objectionable organisms where applicable.
- Physicochemical tests — pH (if applicable in solution), refractive index or other identity tests, and water activity where relevant.
- Allergen statement and processing‑cross‑contact declarations.
- Certifications — supplier and facility certifications such as JAKIM Halal, GMP, HACCP and FSSC 22000. Facility registration (e.g. US FDA Registered) where required by destination market.
- Specification sheet — comprehensive specification with analytical methods referenced and acceptance criteria.
5. How to source Myo‑Inositol in bulk
Practical considerations for procurement:
- MOQ & pack sizes: Suppliers typically offer trial/sampling packs up to drums and container loads. Common packing tiers: sample sachets, 1 kg, 5 kg, 10 kg, 25 kg drums; customised primary packaging available on request.
- COA & sample requests: Always request a recent lot COA and, where possible, a physical sample from the lot you intend to buy to verify analytical parameters and handling properties.
- Lead times: Lead times depend on stock availability, order size and destination. For bulk container orders, allow additional manufacturing or allocation time. Request lead‑time estimates in writing as part of the quotation.
- Supplier evaluation: Verify facility certifications (GMP, FSSC 22000, HACCP), export experience to your target market, and the supplier’s ability to provide lot‑traceable COAs and technical support.
- Export documentation & compliance: Confirm the supplier provides export paperwork, halal certificates (JAKIM) where required, commercial invoices, packing lists and any destination‑specific certificates you require.
- Logistics & storage: Plan inbound logistics with attention to humidity control and storage below 25°C to maintain free‑flowing powder quality.
6. B2B FAQ
What is a typical purity specification?
Commercial Myo‑Inositol is typically supplied at ≥99% purity by assay. Suppliers should specify the analytical method used (HPLC, UPLC or equivalent) and provide the lot COA.
Can you provide a COA before purchase?
Yes. Reputable suppliers will provide a recent lot COA and a full specification sheet on request so your technical or regulatory teams can perform pre‑purchase checks.
Are samples available for formulation testing?
Yes. Request evaluation samples or R&D trial packs. Ensure the sample is from the same production lot you intend to purchase, or request a lot‑specific sample where possible.
How should the material be handled in production?
Handle and store under low humidity and below recommended storage temperature (see specification). Use closed systems or local dust extraction for bulk handling, and verify compatibility with your dosing and encapsulation equipment during small‑scale trials.
Can the supplier support OEM or private‑label packing?
Many suppliers offer OEM and private‑label services through contract manufacturing networks. Confirm packaging options and labelling capabilities when requesting quotations.
