Maurice Ekpenyong

Hello Hemanga, Yes, all the compounds listed are natural solvents (meaning they could be obtained from natural sources). The desired characteristics of a green solvent include no flammability, ease of availability from natural and renewable sources, biodegradability, low or negligible toxicity, and so on. When the compounds that constitute the solvent are primary metabolites, namely, amino acids, organic acids, sugars, or choline derivatives, then they are natural (green) solvents. Please read the attached for natural solvents with high volatility.

Hemanga Hazarika

Thanks a lot Maurice Ekpenyong . I have one more query. Can you please tell me, if a formulation contains deodorised kerocene along with herbal derivatives (active constituents) could claim for herbal product? Deodorised kerocene itself is an organic solvent.

I want to believe that your kerocene means kerosene. Yes, deodorized kerosene is an organic compound since it could go by the name paraffin, lamp oil, or coal oil depending on the region of the world in which it is sold. Except you wish to go all the way to oleogenesis, then deodorized kerosene is not a herbal product but just as you said, a formulation containing herbal compounds.
