Soap (Exemplar) - Chemistry LibreTexts

Aug 18, 2020·Effect of Hard Water. If soap is used in "hard" water, the soap will be precipitated as "bath-tub ring" by calcium or magnesium ions present in "hard" water. The effects of "hard" water calcium or magnesium ions are minimized by the addition of "builders". The most common "builder" used to be sodium trimetaphosphate.

Sodium Hydroxide and Soap Making

Sodium Hydroxide (NaOH), also known as lye, is an essential ingredient in the soap making process. When sodium hydroxide beads or flakes are mixed with a liquid, a lye solution is created. This solution, when mixed with fats and oils, will cause a chemical reaction called saponification. The result of saponification is beautiful handmade soap.

Is Soap Still Natural If Made with Sodium Hydroxide or Lye ...

The short answer is yes, the soap is still natural. Soap making requires sodium hydroxide, which is more commonly known as caustic soda or lye. That means every soap found in the market have been made using lye. As long as the other ingredients are natural, the soap will stay natural during the soap making process because lye is not present in the final product. Most soap companies, unlike Men ...

Sodium Hydroxide | NIOSH | CDC

Sodium hydroxide (NaOH) is a an odorless, white crystalline solid that absorbs moisture from the air. Sodium hydroxide is very corrosive. It can cause irritation to the eyes, skin, and mucous membrane; an allergic reaction; eye and skin burns; and temporary loss of hair. Workers may be harmed from exposure to sodium hydroxide. The level of harm depends upon the dose, duration, and work being done.
