VOCs have a boiling point range in °C of 50-100 to 240-260. VVOCs have a boiling point range in °C of <0 to 50-100. Very volatile organic compounds are so volatile that they are difficult to measure and are found almost entirely as gases in the air rather than in materials or on surfaces. The higher the volatility (lower the boiling point), the more likely the compound will be emitted from a product or surface into the air. Since VVOCs have lower boiling points than VOCs, they are more likely to be emitted from a product or surface into the air.
