3-Oz Neutrogena SPF 55 Ultra Sheer Dry-Touch Sunscreen Lotion Expired

Yeah, so according the petition noted above, the use of benzene is generally not permitted as a solvent in the manufacture of cosmetics except where manufacturing necessity exists. Where it is necessary (which the petitioner argues it is not), the limitation of concentration in the final product is 2 parts per million. OSHA sets a limit for work in an environment where you come into occupational or continuous contact with benzene in concentrations greater 10ppm for 8 hours a day. (Only NIOSH's numbers are quoted: 0.1ppm for 10 hours a day/40 hours a week, 1ppm for 15 minute exposure). Note that, in drinking water the EPA limit concentration should not exceed 0.2ppm over a 10 day period (generally 5ppb is the limit for continuous use). The testing method used indicated traces of benzene with *blank* test cards - i.e. the machine found benzene where there should be none. That was subtracted in a statistical basis in an attempt to zero out the known erroneous results. The testing lab inferred that 0.1ppm was their minimum detection level for statistical significance. There is no transdermal absorption standard, in ug, available to determine the dose from a typical application of sunscreen and the NIOSH/OSHA standards are generally geared towards airborne or submerged skin contact.

tl;dr that summary - OSHA says 10ppm for 8 hours a day / 40 hours a week is the limit of exposure. NIOSH says 0.1ppm continuously or 1ppm for 15 minutes is okay.

Neutrogena Ultra Sheer SPF 55 was not tested.
Ultra Sheer 70 was tested at 0.13ppm, barely above the 0.1ppm testing limit
There were two gels and one lotion above 1ppm, none were Neutrogena

The study did not compare the relative cancer risk of UV exposure to the risk of Benzene exposure.

that would be four aerosol sunscreens - found to contain benzene - it says clearly here that this is a lotion.

I don't see how that's relevant to my comment about the photo editing war between Adobe and Corel.
