Product Overview

Magnesium hydroxide (Mg(OH)2) is an inorganic compound widely used in environmental and industrial applications. Bulk buyers typically confirm purity/assay basis, particle size distribution, and market-specific impurity limits with batch-based COA. MSDS and TDS/spec sheet can be provided upon request.
In commercial supply, it is typically offered as a white powder with low-solubility characteristics, and buyers often review assay basis, material form, and release limits before evaluation.
It is commonly considered for tablets, suspensions, selected fortified systems, and industrial-use discussions, with batch documentation and specification review available for sourcing reference.

Applications

Pharmaceutical / Tablet Systems

Suitable for selected tablet, suspension, and oral-system discussions where low-solubility behavior, assay basis, and release limits need to be reviewed in advance.

Food & Nutritional Use

Can be discussed for selected food or nutrition-related systems where specification fit, processing conditions, and destination-market requirements are confirmed before scale-up.

Industrial Evaluation

Also reviewed for industrial-grade and flame-retardant-oriented projects where particle condition, purity, and application-specific limits are part of technical evaluation.

Technical & Formulation Notes

Technical Notes

Technical review should focus on assay basis, low-solubility material behavior, release specification, and the exact grade discussion used for commercial supply. Buyers are advised to confirm formulation fit and destination-market requirements in the TDS and COA before evaluation.

Typical production includes controlled precipitation or conversion processes, followed by filtration, drying, milling/classification, and in-process QC. Final release is based on agreed specifications such as purity/assay basis, moisture/LOD, particle size distribution, and market-specific limits.

Magnesium Hydroxide Powder should be reviewed within the final formulation or processing system rather than as a standalone raw material.

For tablet, suspension, or selected fortified systems, buyers usually confirm:

  • material form

  • low-solubility behavior

  • release specification

  • compatibility with the intended process

Final suitability should be validated through internal testing based on the actual application.

- Identity and purity/assay (as specified)
- Moisture / LOD (per spec)
- Particle size distribution (D50/D97) or mesh (grade dependent)
- Bulk density / flowability (if required)
- Heavy metals (limits per destination market/grade)
- COA-to-lot traceability

Storage, Shelf Life & Packaging

Storage

Store in a cool, dry, and well-ventilated area. Keep tightly sealed in the original container with inner liner intact. Protect from moisture and direct sunlight. Reseal immediately after opening.

Moisture control is recommended during transit and warehouse operations (e.g., desiccant when applicable).

Shelf Life

24 months from the manufacturing date when stored in the original, unopened packaging under recommended conditions. Refer to the COA/batch label for the exact retest/expiry information.

Packaging & Logistics

Sample Packing

1–5 kg aluminum foil bag; shipping charged.

Bulk Packing

Typically 25 kg/bag, carton, or drum with inner liner.

Customization

Custom packaging, labeling, and shipping-mark discussion can be arranged according to destination and application needs.

Logistics & Documents

Packing configuration and document pack should be aligned before shipment to support handling, storage, and destination-market review.
