Summary: 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.

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard uses the redrafted law revision using ISO 2870.2009 "detergent surfactants can be hydrolyzed under acidic conditions and Determination of "non-hydrolyzable anionic actives. This standard and ISO 2870.2009 as compared to the existence of technical differences, these differences involve the provision has passed in the outside bit blank page Opposed to a single vertical line (|) have been identified in Appendix A gives a list of corresponding technical differences and the reasons. The standard proposed by China National Light Industry Council. This standard by the National Standardization Technical Committee and the detergent surfactant (SAC/TC272) centralized. This standard was drafted. China Daily Chemical Industry Research Institute, surfactants and detergents Industry Productivity Promotion Center. The main drafters of this standard.

1 Scope

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.
