Safety Summary: 10% Niacinamide Face Serum with 2% Zinc

Is 10% Niacinamide Face Serum with 2% Zinc laboratory tested? Yes. It was independently tested at Sigma Test & Research Centre, a laboratory accredited by NABL (Accreditation No. TC-15193). The tested sample belongs to batch AC5B023.

Heavy metals not detected. Lead, cadmium, arsenic and antimony were below the laboratory's detection limit of 0.25 mg/kg, while mercury was below its detection limit of 0.1 mg/kg.

Microbiological quality. Total microbial count was less than 10 cfu/g against a limit of NMT 1000 cfu/g. Total yeast and mould count was less than 10 cfu/g against a limit of NMT 100 cfu/g.

Measured pH. The laboratory recorded a pH of 5.11 for the tested sample.

1,4-Dioxane not detected. The laboratory reported this substance as not detected at a detection limit of 1.0 mg/kg.

Sulphate-free and paraben-free. The published product ingredient list contains no sulphates, parabens, silicones or mineral oil. This information comes from the ingredient list, not from the laboratory report.

Scope of these results. Findings apply to the tested batch and specified laboratory parameters. Skin tolerance is assessed separately in dermatological patch testing. NABL accredits laboratories, not products.

Understanding These Tests for 10% Niacinamide Face Serum with 2% Zinc

Physical & Organoleptic

The laboratory recorded the tested sample as a colourless viscous liquid with a characteristic odour.

These observations document the sample's physical properties at the time of testing.

Chemical Parameters

The report records pH 5.11, density 1.022 g/ml and total residue 8.33% w/w. 1,4-Dioxane was not detected at a laboratory detection limit of 1.0 mg/kg.

No specification limit was provided for these chemical parameters in the certificate.

Heavy Metals

Lead, cadmium, arsenic and antimony were not detected at the respective 0.25 mg/kg detection limit. Mercury was not detected at 0.1 mg/kg.

Not detected means that the measured substance was below the stated detection limit, not necessarily completely absent.

Microbial Counts

Total microbial count and total yeast and mould count were both less than 10 cfu/g.

These results were within the report's specified microbiological limits.
