As discussed in Section 4.3, the CPSC determined that by the late 1970’s, benzene had been
phased out of consumer products intended for use in the home (CPSC, 1978, 1980; NTP,
2002). In deciding to withdraw a proposed ban of benzene in consumer products, the CPSC
also determined that trace amounts of benzene are not likely to result in significant exposure to
benzene vapor (NTP, 2002). The only consumer product which contains benzene in percent
quantities is gasoline and exposures to gasoline in various scenarios have been evaluated (i.e.,
in-vehicle, refueling, small, non-road engine). A consumer product study conducted by EPA
(Sack and Steele, 1991) identified several products containing benzene. In this study, 1,159
consumer products from 65 product categories were analyzed for VOC content by GC/MS with
a detection limit of 0.1% by weight. Of the 63 product categories tested, four product categories
were identified that contained greater than 0.1% benzene and are listed on Table 7.46.
Table 7.46: Summary of Benzene Consumer Product Weight Contents
Quantified by Sack and Steele (1991) Greater than 0.1% by Weight
Product Category % by weight*
silicone lubricant 0.1 – 0.25
carburetor and choke cleaner 0.25 – 0.75
gasket adhesives/removers 0.25 – 0.75
spot remover 0.25 – 0.75
* Product categories were placed in weight ranges based on the average of the test
results for individual products. Weight percents were calculated by excluding those
products where benzene was not detected.
Because the Sack and Steele study is somewhat dated (i.e., 1991) benzene composition for
each of the products was verified with current material safety data sheets (MSDS). Tables 7.47
and 7.48 show the product categories and representative products that Sack and Steele
identified as containing greater than 0.1% benzene. When the benzene contents of these
products were verified using the actual product MSDSs, it was found that all benzene contents
were less than 0.1% and that benzene was not listed as an ingredient on any MSDS.
