Standards change. Your supply does not.

Pharmacopoeias such as the IP, BP, USP, Ph. Eur. and FCC revise their standards from time to time. Rhine prepares for every revision before it comes into force. The latest example: our grades already meet the revised Indian Pharmacopoeia (IP 2026). Whichever standard you buy against, your product arrives updated and your paperwork arrives with it.

Latest example: IP 2026

Our grades already meet the revised Indian Pharmacopoeia.

Consistency

Always inside the limits.

Every magnesium salt must stay between a lower and an upper limit. The green band shows where Rhine batches sit: comfortably inside the limits, batch after batch, year after year. That is what consistency means at Rhine. For you, it means a stable product in every order, wherever in the world you buy from.

The process

Closed processing, from reaction to packing.

Rhine has re-imagined proven equipment designs and rebuilt them for pharmaceutical work: stainless steel 316, closed from reaction to packing. Four key steps:

Agitator driveJacketDischarge valve
01

SS316 equipment

All product-contact equipment is pharmaceutical-grade SS316 stainless steel, cleaned under validated protocols.

BlowerClosed pipelineCycloneRotary valve
02

Closed transfer

Product moves through closed pipelines from stage to stage. It is never touched by hand and never lies open to the air.

Magnetic separation

Every powder and granule stream passes through in-line magnetic separators that remove metallic particles before packing.

Testing and packing

Every batch is tested in the laboratory against the monograph and packed with its COA.
