Potassium hydroxide is an inorganic compound with the formula KOH. Along with sodium hydroxide, this colourless solid is a prototypical "strong base". It has many industrial and niche applications. Approximately 100 times more NaOH than KOH is produced annually.
Although more expensive than using sodium hydroxide, KOH delivers a higher kinetic and volumetric performance, ie higher efficiency, during the manufacture of biodiesel via transesterification of vegetable oil and the resultant glycerol, of which, remains liquid under a wide temperature range. 25kg product is package in UN approved dry lined 2 layer sacks.
