Dimethicone 

Dimethicone is an orally active biochemical assay reagents consisting of a fully methylated linear siloxane polymer whose ends are blocked by trimethylsiloxane units. Dimethicone can lubricate hair and physically block the respiratory system of lice to remove lice. Dimethicone has potential applications in cosmetics and daily cleaning products^[1][2][3].
