Caustic soda ke e 'ngoe ea lik'hemik'hale tse sebelisoang haholo. E sebelisoa ho fokotsa acid; ho etsa letsoai la sodium; ho potlakisa tšepe astheir hydroxides; tlhoekisong ea peterole; ka thesaponification ea esters; ho phekola cellulose, polasetiki le rabara; le lits'ebetsong tse ngata tsa synthetic le tsa tlhahlobo.

Sodium hydroxide e rekisoa e le li-flakes kapa li-pellets tse anhydrous kapa e le 50% kapa 73% ea tharollo ea metsi. E na le litšebeliso tse ngata tsa indasteri 'me ke e' ngoe ea lik'hemik'hale tse 10 tse holimo mabapi le tlhahiso le tšebeliso lefatšeng ka bophara. Ho sebelisoa lithane tse ka bang limilione tse 15 tsa sodium hydroxide selemo le selemo. Tšebeliso ea eona e kholo ka ho fetisisa, e jang hoo e ka bang halofo ea tlhahiso ea eona, ke motheo oa ho hlahisa lik'hemik'hale tse ling. E sebelisoa ho laola pH le ho fokotsa acid ka mekhoa ea lik'hemik'hale. Indasteri ea pampiri e sebelisa haholo sodium hydroxide ts'ebetsong ea pulping. Sodium hydroxide e sebelisoa ho arola likhoele ka ho qhaqha lignin e kopanyang. E sebelisoa ka mokhoa o ts'oanang ha ho etsoa rayon ho tloha cellulose. Sodium hydroxide ke k'hemik'hale ea bohlokoa indastering ea sesepa. Ts'ebetsong ea saponification, triglycerides e fumanoang liphoofolong le limela e futhumatsoa ka tharollo ea abasic ho fana ka glycerol le sesepa:

Sodium hydroxide e sebelisoa indastering ea masela bakeng sa ho soeufatsa le ho phekola masela ho etsa hore li dae habonolo. Indasteri ea petroleum e sebelisa sodium hydroxide ho cheka seretse le asa bactericide. Sodium hypochlorite (NaOCl) e sebelisoa haholo bakeng sa ho hloekisa le joalo ka sebolaea likokoana-hloko.Bleach e tloaelehileng ea malapa e na le hoo e ka bang 5% ea sodium hypochlorite solution. Sodiumhypochlorite e lokisoa ka ho arabela chlorine ka sodium hydroxide: Cl2(g) + 2NaOH(aq) →NaOCl(aq) + NaCl(aq) + H2O(l). Sodium hydroxide e sebelisoa indastering ea lijo bakeng sa ho hloekisa le ho ebola litholoana le meroho. Sodium hydroxide ke motsoako o monyane lihlahisoa tse ngata tse tloaelehileng, empa ho tse 'maloa e ka ba karolo e fetang halofo ea sehlahisoa. Li-dranocrystals li na le pakeng tsa 30% le 60% sodium hydroxide 'me tse ling tse hloekisang metsi li ka ba le 100% sodium hydroxide.
