HD caustic soda is in the form of microgranules.

However, you have to be careful, because soda reacts strongly when combined with water and generates large amounts of heat – the solution foams a lot and can splash, so the treatment must be carried out with gloves and covered face (soda combined with water gives off irritating vapors).

Do not use too much soda, because it can crystallize in the sewage pipes and completely clog them. The preparation must not be used for aluminum installations and on galvanized surfaces because it may damage the installations. Caustic soda reacts very strongly with aluminum.

The use of caustic juice in the bleaching of wood

The use of Caustic Soda in the production of soap

The traditional recipe for soap production consists in mixing fat (e.g. vegetable oils) with sodium hydroxide. The use of caustic soda in the form of lye causes the so-called the reaction of saponification of fats – after a few hours, the mixture produces sodium soap and glycerin, which together form the so-called grey soap. Recently, it is quite popular to use caustic soda at home, because more and more people struggle with skin allergies, and the soap is free from irritants.
