GB/T 13530-2023 Test methods for sodium ethoxylated alkyl sulfate
Basic Information
Scope
This document describes the methods for determining the total active ingredient content, the content of non-sulfonated substances, and the average molecular weight of sodium alkyl sulfate ethoxylate.
This document is applicable to the determination of sodium alkyl sulfate ethoxylate.
The method for determining the total active ingredient in this document is also applicable to the determination of the total active ingredient in sodium alkyl phenol sulfate ethoxylate, which includes organic substances soluble in ethanol: sodium alkyl sulfate ethoxylate (or sodium alkyl phenol sulfate ethoxylate), polyethylene glycol sulfate, and non-ionic components; the method for determining the average molecular weight is applicable to sodium alkyl sulfate ethoxylate products with no more than 20 ethylene oxide groups in each molecule.
