Scope

This standard applies to the determination of trace amounts of 1,4-dioxane, in
the surfactants, which are produced from ethylene oxide as raw materials, such
as ethoxylated alkyl sulfates and polyethylene glycols. For the personal care
products, which contain such surfactants, it may also refer to the method, which
is determined by this standard, to determine the content of 1,4-dioxane.
This standard applies to the determination of samples, which contain not less
than 5 mg/kg 1,4-dioxane (using a hydrogen flame ionization detector) or 2.5
mg/kg 1,4-dioxane (using a mass selective detector). When the content of 1,4-
dioxane exceeds 100 mg/kg, it is necessary to increase the concentration of
the standard solution OR dilute or reduce the sample for determination.

Summary	This standard applies to the production of ethylene oxide as raw material surfactants, such as ethoxylated alkyl sulfate, polyethylene glycol and other products of trace residues of 1, 4 Dioxane (1, 4 dioxane) determination. Such surfactant -containing personal care products may also refer to the use of this standard to determine the method for the determination contained 1, 4 Dioxane (1, 4 dioxane). This standard applies to the determination contains not less than 5mg/kg 1, 4 dioxane (using a flame ionization detector) or 2. 5mg/kg 1, 4 dioxane (using mass selective detector) of the sample, when 1, 4 dioxane content of more than 100mg/kg, the need to increase the concentration of the standard or sample dilution or reduction measured.
