Hexane is a solvent commonly employed in the extraction process of oils from various seeds, including castor beans. The purpose of this extraction is to separate the oil from the solid plant material. Residual amounts of the solvent may be present in the final product, depending on the efficiency of the manufacturing processes used to remove it.
The presence and levels of such solvents are a point of focus due to potential health concerns associated with exposure. Regulatory bodies often set limits on the allowable concentration of these residual solvents in products intended for human consumption or cosmetic application. Historical context shows that extraction methods have evolved to minimize solvent residue, driven by consumer demand for purer products and advancements in technology.
