Introduction

The nickel, antimony and tellurium substances in this standard are the prohibited components specified in China's "Cosmetic Safety Technical Specification" (2015 edition) Cosmetics production of raw materials and components added to the cosmetics, if the technology can not avoid the ban on substances as impurities into the cosmetics, the make-up The ingredients should conform to the general requirements for cosmetics in the Cosmetic Safety Technical Specification (2015 edition), ie, in normal and reasonable foreseeable Under conditions, shall not be harmful to human health. At present, China has not yet set the limits of these substances, the development of this standard, only the determination of these substances in cosmetics to provide detection methods. Determination of nickel, antimony and tellurium in cosmetics Inductively Coupled Plasma Atomic Emission Spectrometry

1 Scope

This standard specifies the determination of nickel, antimony and tellurium in cosmetics by inductively coupled plasma emission spectroscopy. This standard is applicable to the determination of nickel, antimony and tellurium in cosmetics. The standard method of detection limit. nickel 0.06mg/kg, antimony 0.15mg/kg, tellurium for 0.3mg/kg. The standard method of quantification limit. nickel 0.2mg/kg, antimony 0.50mg/kg, tellurium for 1.0mg/kg.

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. GB/T 6682 Analytical laboratory water specifications and test methods

3 method summary

After the sample is digested with acid, the inductively coupled plasma emission spectrometer is injected into the plasma, the excited atoms and ions The atomic spectrum and the ion spectrum are emitted, and the content of the characteristic line of the element is measured.
