• Multi-element: Tests for many metals at once, saving time and cost.
• Regulatory support: Meets strict international safety limits, such as those from the EU and FDA.

Example Use

A lipstick brand uses ICP-MS to check for trace amounts of lead. Even 1 part per billion can be detected—helping the company prove safety claims and comply with regulations.

Non-obvious Insight

Not all metals are harmful. ICP-MS can also confirm the presence of beneficial minerals, like zinc or iron, ensuring product claims are accurate.

Lc-ms/ms: Liquid Chromatography–Tandem Mass Spectrometry

LC-MS/MS combines the separation power of liquid chromatography with the detailed identification of mass spectrometry. It is now a gold standard for analysing complex cosmetic formulas.

Benefits for Cosmetics

• Detects very low amounts of preservatives, fragrances, and allergens.
• Differentiates similar molecules (like isomers), which older techniques can miss.
• Monitors product stability by spotting ingredient breakdowns.

Example Use

A skincare company checks for trace levels of banned preservatives (such as formaldehyde donors) using LC-MS/MS. This allows them to guarantee “free-from” claims.

Non-obvious Insight

LC-MS/MS can reveal hidden reaction products formed during storage. Finding these early helps brands fix formulas before launch, reducing the risk of recalls.

Portable Spectroscopy

Portable spectroscopy tools, like handheld Raman or FTIR devices, are revolutionising in-field and on-site analysis. No longer do samples always need to be sent to a lab.

Advantages

• Rapid checks: Test raw materials or finished goods instantly on the factory floor.
• Non-destructive: No need to destroy the sample for testing.
• Traceability: Immediate scanning supports better supply chain control.

Example Use

A quality control manager uses a portable Raman spectrometer to verify incoming plant extracts before accepting a shipment. If there’s a mismatch, the batch is rejected on the spot.
