GB/T 28192-2011 — This standard specifies an anionic detergent Test hydrolyzed and non-hydrolyzed under acidic conditions. This standard applies to active species are alkyl sulfates, alkyl phenol ether sulfates and fatty alcohol ether sulfates.
If the active substance content of the mass fraction expressed, the two types of average molecular weight of the surfactant must be known or measured in advance.
If detergents containing an oxidizing agent, it must be destroyed before hydrolysis.

What this standard covers
This standard specifies an anionic detergent active materials can be hydrolyzed under acidic conditions and non hydrolysis testing methods. This standard applies to active species are alkyl sulfates, alkyl phenol ether sulfates and fatty alcohol ether sulfates. If the active substance content of mass fraction, the two types of surface active agent has an average molecular weight must be known or determined in advance. If a detergent containing oxidizer, you must destroy before hydrolysis.
