It is disclosed a bio-based composition derived from a lignin of a ligno-cellulosic biomass comprising at least 50% by weight of aromatic compounds, which can be monomeric aromatic compounds and non-monomeric aromatic compounds. The monomeric compounds have a molecular weight which is less than 210gr/mole. The bio-based composition has an acidity which is less than 80 mg KOH/g, and it is stable over time. Namely, the amount of monomeric aromatic compounds does not decrease by more than 2% of the aromatic compounds by weight after storing the composition for a time between 1 week and 1 year in sealed conditions.
