# Pharma-Grade Sorbitol: Pharmacopoeia Requirements and Documentation

When sorbitol goes into a medicine or a medical device, the grade and the paperwork matter as much as the chemistry. Pharma buyers need documented purity and a supplier who understands the standards.

Pharmacopoeia grades
--------------------

Pharma-grade sorbitol must meet the requirements of the relevant pharmacopoeia, which set limits on residual sugars, heavy metals, water content and microbial counts. The grade is defined by the monograph, not by a marketing description.

Documentation
-------------

- Certificate of analysis per lot.
- Statement of pharmacopoeia conformity.
- Change-control notifications for any process change.

**Buyer tip:** qualify the supplier and the site, not just the material; site changes can invalidate a qualification.

Impurity control
----------------

Short-chain impurities and peroxide-forming residues can attack sensitive actives. Specify the limits that matter for your formulation and verify them with incoming testing.
