Over time, these organic compounds react with temperature, light and moisture, they begin to break down and release VOCs.VOCs are volatile organic compounds (short for Vocatile Organic Compound).
These compounds easily mix into the air, creating the aroma of old books.
There are many different types of VOCs: VOC valinin with vanilla-like scent, VOC benzaldehyde with aromatic aroma and VOC ethylbenzene with a sweet aroma.
