Bromacil is available in granular, liquid, water-soluble liquid, and wettable powder formulations. Lower critical surface tension means a less wettable material surface. Endosulfan can be produced as a liquid concentrate, wettable powder or smoke tablet. Such a surface is said to be fully wettable by the liquid. It is typically sold as wettable granules mixed with water before spraying. It is formulated as emulsifiable concentrates, wettable powders, dusts, ready-to-use liquids, and aerosol sprays. Wettable powders are designed to be applied as a dilute suspension through liquid spraying equipment. For water, a wettable surface may also be termed hydrophilic and a nonwettable surface hydrophobic.
