| ExxonMobil Chemical offers LVP Fluids that meet the vapor pressure criterion specified in the federal and California consumer product regulations as well as the Ozone Transport Commission's model rule on consumer products. All meet California's boiling point threshold (>216°C) using ASTM D86-96, and the vapor pressure of the most volatile ones have been confirmed using Isoteniscope -- ASTM 2879-97, as modified in California Air Resources Board Method 310, November, 1998.
A statement certifying the LVP-VOC status of these products is included on applicable ExxonMobil Chemical Sales Specification sheets and Material Safety Data Sheets (MSDS).

"Partial LVP-VOCs"
Although California's regulation allows partial exemption for consumer product ingredients which distill at temperatures >216°C, the manufacture of complex, multi-constituent ingredients is not conducted in a manner which may control carbon number distribution and/or boiling range distribution.
Due to the absence of manufacturing controls which could prevent the batch-to-batch variability and consequently shifting carbon number/boiling range distributions, ExxonMobil Chemical does not broadly recommend use of products which only partially meet CARB's LVP-VOC boiling point criterion.
Additionally, since the National Volatile Organic Compounds Emissions Standard for Consumer Products references vapor pressure or carbon number as the only criteria for LVP-VOC status, the position of the USEPA is unclear on the issue of partial LVP-VOC status for solvents or other consumer product ingredients.
