35 Sunscreens Tested: No Benzene Detected, Lead Found in All 35. Sunscreen Contaminant Screening: Residual Solvents and Heavy Metals

A consumer-health company screened 35 retail sunscreens for four metals and twenty residual solvents. Lead was quantified in every product, from 0.006 to 4.960 mg/kg. Cadmium was quantified in 21 products. Every product with quantified cadmium had lead at or above 0.125 mg/kg, and every product without it had lead at or below 0.079 mg/kg. All four products whose certificate names include “mineral” fell in the cadmium-positive group. Benzene was not detected in any product.

Key numbers

Table 3, PDF pp. 8-10, mg/kg in the unit as submitted. The limit of detection is 0.001 and the limit of quantitation 0.004 mg/kg for all four elements. ND is below the detection limit; “<LOQ” is detected below quantitation. Products are reported here by code in the table’s printed order (OH-01 to OH-35, sorted by lead); the certificate names are in the source.

Lead: quantified in 35 of 35, range 0.006 (OH-35) to 4.960 (OH-01). Five products exceeded 1 mg/kg and one exceeded 2 mg/kg.
Cadmium: quantified in 21 of 35, from 0.005 to 0.603 mg/kg; seventeen exceeded 0.1 mg/kg; fourteen were ND.
Arsenic (total): quantified in 9 products, 0.005 to 0.189 mg/kg.
Mercury (total): quantified in 3 products, 0.004 to 0.009 mg/kg.
Median lead was 0.620 mg/kg in the 21 cadmium-quantified products and 0.0165 mg/kg in the 14 cadmium-ND products. These medians, the 38-fold ratio, and the 827-fold lead range all reproduce from Table 3.
The four products with “mineral” in the certificate name (OH-11, OH-16, OH-18, OH-21) had lead of 0.620, 0.379, 0.231 and 0.125 mg/kg and cadmium of 0.211, 0.187, 0.145 and 0.418 mg/kg.
The product whose name indicates a baby line (OH-12) had lead 0.613 and cadmium 0.109 mg/kg, arsenic below quantitation and mercury ND. The two kids sprays had lead 0.589 (cadmium 0.073) and 0.007 mg/kg (cadmium ND).
Ten of the fourteen cadmium-ND products are described as sprays (Table 4, PDF p. 12).

All 140 values are kept in the structured evidence record for this source.

Methods (brief)

Oasis Health bought the products and sent one unit of each to an unnamed laboratory accredited to ISO/IEC 17025:2017 (Order No. 594282; received 23 July 2026, reported 30 July to 6 August 2026). Metals were measured by ICP-MS after microwave acid digestion by AOAC Official Method 2015.01. Solvents were measured by GC-MS under USP 467. The report states that AOAC 2015.01 was validated for food and beverages, that the certificates do not describe digestion well enough to judge recovery from mineral particles, and that any shortfall would understate content. Formulation and active ingredients were not recorded by the laboratory.

Evidence fitness

The table supports as-sold results for four metals in 35 single units at a uniform, low quantitation limit. It supports the descriptive observation that cadmium detection and lead level travel together in this panel, which the authors read as pointing to a shared ingredient, while stating that the panel cannot identify it. It does not support a statement about true total content where particles resist digestion, a population prevalence, or which brand is safer.

The report compares results with an FDA lead guidance value for cosmetics, Washington State figures and a Proposition 65 dose level. Those instruments are not in this collection and are not used here. The report also gives an order-of-magnitude estimate of lead placed on skin (about 170 µg for one whole-body application of the highest-lead unit) and a bounded absorbed amount. These are the source’s estimates, not measurements.

Limitations

One unit per product, no second lot, retail-availability selection, and an unnamed laboratory. “Mineral” and “spray” are words from certificate names, not verified formulation attributes. The self-description “peer reviewed” is not supported by any stated review process.
