What is sodium hydroxide?

Sodium hydroxide (NaOH) is white in colour and does not have a smell. This is a common element in cleaning inventory, and may mainly appear in drain and oven cleaning. Sodium hydroxide causes the skin to burn upon contacts and will cause irrevocable damage if ingested.

However, sodium hydroxide is FDA approved and "generally recognized as safe". Used in various industries, some sodium hydroxide applications include textiles, soap and cleaning products, paper, aluminium processing, petroleum, and bleach production. You can buy sodium hydroxide in powder liquid and crystal form.

Chemical is synthesized through electrolysis where chemical decomposition is achieved by passing electricity through sodium chloride solution (generally referred to as salt tables) to produce sodium hydroxide and chlorine gas.

The inclusion of sodium hydroxide in many beauty products is attributed to its ability to stabilize pH levels. The inclusion of sodium hydroxide in hair products creates a less acidic environment for the scalp, skin, and hair. The levelling effect of sodium hydroxide helps regulate external influences which may have otherwise changed healthy pH levels. A common example is the mixture of residual oils on one’s hands introduced to the conditioning product upon application.
