Laboratory Testing

The lab results, in full.

Cham products are tested by an independent laboratory against GSO 1943:2024, the safety standard for cosmetics and personal care products. The results are printed below as text so you can read them here, and the signed report is linked alongside each one.

Brightening Face Cream

Chemical and microbiological analysis

Middle East Testing Services tested a 50 g sample from batch 20251123 across pH, 1,4-dioxane, five heavy metals, eighteen polycyclic aromatic hydrocarbons, twenty-four fragrance allergens and six microbiological parameters. Everything on this page is transcribed from that report.

ND means not detected, or below the detection limit. DL is the detection limit for that method. CFU means colony forming units. A dash in the limit column means GSO 1943:2024 sets no numeric limit for that parameter, so the result is reported without one.

Testing was carried out at the laboratory's Ajman site. The results apply to the sample and batch named above.
