A consumer-advocacy business had one unit of a baby mineral sunscreen lotion with prebiotics, SPF 55 tested by a commercial laboratory for lead, cadmium, mercury and arsenic and published the report. The published headline is: “Testing Hello Bello SPF 55+ Baby Mineral Sunscreen Lotion + Prebiotics for Lead, Cadmium, Arsenic, & Mercury with Independent, Third-party Laboratory Analysis”. This page reports the result by laboratory case number.
Key numbers
Laboratory report image, PDF p. 16. Case 2507165-01, received 07/10/2025, tested 07/14/2025, completed 07/15/2025. Units are ppb (µg/kg) in the product as received.
| Analyte | Result (ppb) | Method |
|---|---|---|
| Lead | 169.2 | ICP-MS |
| Cadmium | 166.1 | ICP-MS |
| Arsenic (total) | 485.3 | ICP-MS |
| Mercury (total) | < 5.00 | ICP-MS |
The same test appears as row 10 of the 2026 comparison chart with the same values. Total arsenic in this unit (485.3 ppb) is the highest arsenic value on the 36-row chart. The method does not speciate arsenic, so the inorganic fraction is unknown. Ledger rows MBS-0158 to MBS-0161.
Methods (brief)
The unit was sent to the laboratory with an anonymised sample description and an internal lot number, and the report was annotated with the product name afterwards. The report states ICP-MS and prints reporting limits through the less-than values. It does not describe the digestion, sample mass, recovery or quality control. The collection notes said this image had not been visually checked. It was read directly for this page and matches the chart.
Evidence fitness
The report supports one measured result for each metal in one unit as sold. It is useful as a data point alongside other sources and as a record of the reporting limits used. It does not describe other lots, the brand’s current product, or the fraction of metal that crosses infant skin. Arsenic and mercury are totals.
Limitations
One unit, one laboratory, no replicate and no method detail. Grey literature. The same result is also printed on the comparison chart and must be counted once.
