Key focus categories: cosmetics containing mineral pigments/colorants, whitening and spot removing products, hair dyes, infant and toddler cosmetics, imported cosmetics, and products claiming natural plant extracts.
Applicable scenarios: raw material acceptance, formula research and development, production quality control, factory inspection, filing and declaration, market sampling, toxicological safety evaluation, label review, arbitration testing.
Testing objects: finished products, raw materials (pigments, powders, oils, plant extracts, preservatives), and migration materials of packaging materials.
Testing items
(1) Core mandatory inspection of heavy metals (according to the "Technical Specification for Safety of Cosmetics")
Unit: mg/kg
Lead (Pb): ≤ 10; Infant and toddler cosmetics ≤ 5.
Mercury (Hg): ≤ 1; Excluding eye cosmetics containing organic mercury preservatives.
Arsenic (As): ≤ 2; Infant and toddler cosmetics ≤ 1.
Cadmium (Cd): ≤ 5; Infant and toddler cosmetics ≤ 1.
(2) Expand detection of heavy metals (risk management and specific products)
Hexavalent chromium (Cr6+): The limit value is implemented according to the latest regulations, with a focus on cosmetics and hair dyes.
Nickel (Ni): Total amount and release, with a focus on metal contact products and cosmetics.
Antimony (Sb): a risk screening project that focuses on raw material contamination.
Copper (Cu), zinc (Zn): Content monitoring as impurities or additives.
(3) Morphological and migratory detection
Elemental forms: arsenic (trivalent/pentavalent), chromium (trivalent/hexavalent), mercury (inorganic/organic).
Mobility/Solubility: Simulating the release of heavy metals under sweat/saliva conditions.
Packaging migration: The migration of heavy metal content from packaging materials to products.
(4) Pre testing processing and quality control
Pre processing: microwave digestion method, wet digestion method, dry ashing method.
Quality control: blank control, parallel sample, spiked recovery, standard substance calibration, method validation (linearity, precision, detection limit).
