Borax Pentahydrate
Borax Pentahydrate looks like a simple borate until a batch starts behaving differently in dissolution, buffering, or clarity. The real risk is not just supply, it is performance drift from hydration state, insolubles, and process water sensitivity. We supply Borax Pentahydrate with consistent concentration, documentation support, dependable supply planning, and safer sourcing practices that keep your formulation and approvals stable, backed by Chemical Suppliers in India.
About Borax Pentahydrate
Borax Pentahydrate is a hydrated sodium borate where the hydration state influences active borate delivered per kilogram and practical dissolution behaviour. Buyers typically evaluate assay basis, insolubles, solution clarity, and the supporting COA format that procurement and QA require. Specification alignment and reporting lines can be shared during quotation.

Applications
Home Care
- ♦Borax Pentahydrate is used where borate buffering and borate contribution support formulation stability and performance. Plants typically lock hydration form and solution clarity behavior so batches do not drift in appearance or dissolve time.
Chemical Intermediates
- ♦Borax Pentahydrate is used as a borate source in specific intermediate routes where assay basis, insolubles, and solution behaviour matter for reaction control and downstream filtration.
Safety & Handling
- ♦Avoid dust and protect eyes and skin during charging.
- ♦Store tightly closed and dry.
- ♦Follow the shipment SDS and special handling instructions where reproductive toxicity classification applies.
