Understanding Calcium Hydroxide Food Grade Specifications, Grades and Supplier Selection

Choosing the right Calcium Hydroxide Food Grade (氢氧化钙食品级) comes down to reading the specification sheet correctly. This guide explains the numbers that matter and how to select a supplier you can trust.

Key Specifications of Calcium Hydroxide Food Grade

As an slaked lime / hydrated lime, the product is defined by a small set of parameters:

• Molecular formula: Ca(OH)2
• CAS No.: 1305-62-0
• Appearance: Purity white powder
• Packaging: 25kg / 1000kg bag
• Standard: GB1886.375-2024

Grade and Quality Considerations

Not all industrial water plant treatment chemicals are equal. For Calcium Hydroxide Food Grade, confirm active content, moisture and impurity limits against the cited standard. A reputable slaked lime / hydrated lime supplier provides a Certificate of Analysis (COA) per batch and supports third-party testing.

Selection Checklist

1. Match the application: Raw material for calcium hypochlorite and bleaching powder; flocculant in wastewater and waste gas treatment; petro-chemical additive, gold mining, painting, metallurgy, food.
2. Confirm packaging matches your handling (drum vs. bag, 25kg / 1000kg bag).
3. Verify the standard (GB1886.375-2024) and request documentation.
4. Check lead time and container-load options for export.

Storage and Handling

Store Calcium Hydroxide Food Grade in a dry, ventilated area away from incompatible substances. Follow the MSDS for PPE and spill response. Many buyers combine this product with Polyferric Sulphate (Solid) SPFS in a single sourcing plan to reduce freight and admin cost.
