Profile: Essential Depot offers potassium hydroxide, sodium hydroxide, lye, caustic soda, potash, hydrogen cell electrolyte and soapmaking oils. Lye (sodium hydroxide) and potassium hydroxide are corrosive materials used in making soap, some food products, in fuel cells & in making bio diesel fuel. Hydroxide is hydrophilic which means that it not only attracts moisture and water but it actively absorbs any moisture or water to which it is exposed. Our zinc oxide powder is a French process zinc oxide as defined by ASTM D-4295. It is a very fine particle size, and high purity oxide. It is especially developed to provide a zinc oxide of highest surface area and reactivity, along with minimum setting & opacity. Hydrogen fuel cell is a cleanest emissions fuel that can power a vehicle better then regular gasoline, while also achieving higher engine gas mileage & engine horsepower. The hydrogen boost fuel system is reusable and can be installed & reinstalled in any of the future cars.
