Sections 1.3 and 1.4 are withheld here because the supplier and emergency contact blocks carry your own company details in the draft you buy. Every draft needs review by a competent person before it is issued.
Measured values for Trisodium phosphate, and where each one comes from
6 measured values for 4 properties, read from 1 public database. Every record agrees. Follow any record to read the value at its source.
Melting point
1 record
Fixes the physical state at handling temperature, which the label and the transport class depend on.
