GB/T 30932-2014 Determination of dioxane residue in cosmetics - Headspace gas chromatography-mass spectrometry
1 Scope
This standard specifies the headspace gas chromatography-mass spectrometry for the determination of dioxane residues in cosmetics.
This standard is applicable to the determination of dioxane residues in creams, lotions and shampoos.
The detection limit of dioxane specified in this standard is 0.8mg/kg, and the quantification limit is 2.5mg/kg.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
GB/T 6682 Water for analytical laboratory use - Specification and test methods
3 Principle
The samples were extracted by heating in headspace vials and then determined by headspace gas chromatography-mass spectrometry, with quantification using the internal standard method.
4 Reagents and materials
Unless otherwise specified, analytically pure reagents and Class-I water defined in GB/T 6682 are used.
