GB/T 13530-2008 in English

《GB/T 13530-2008乙氧基化烷基硫酸钠试验方法》由TC272（全国表面活性剂和洗涤用品标准化技术委员会）归口，主管部门为中国轻工业联合会。
本标准规定了乙氧基化烷基硫酸钠中总活性物含量、未硫酸化物含量、平均相对分子质量的测定方法。本标准适用于乙氧基化烷基硫酸钠的测定。本标准的总活性物测定方法也适用于乙氧基化烷基酚硫酸钠总活性物的测定，总活性物包括可溶于乙醇的有机物：乙氧基化烷基硫酸钠（或乙氧基化烷基酚硫酸钠）、聚乙二醇硫酸盐和非离子组分；平均相对分子质量测定方法适用于每个分子中氧乙烯基团数不多于20个的乙氧基化烷基硫酸钠产品。

Scope

This standard specifies the determination methods of total active substance content, unsulfated substance content and average relative molecular mass in sodium ethoxylated alkyl sulfate. This standard applies to the determination of sodium ethoxylated alkyl sulfate. The method for the determination of total active matter in this standard is also applicable to the determination of total active matter of ethoxylated alkylphenol sodium sulfate, which includes organic matter soluble in ethanol: sodium ethoxylated alkylphenol sulfate (or ethoxylated sodium alkylphenol sulfate), polyethylene glycol sulfate and non-ionic components; the method for determining the average relative molecular mass is applicable to ethoxylated alkylsulfates with not more than 20 oxyethylene groups per molecule sodium products.
