Home Hardware stores appear to be the only retailers that carry lye. In July 2014, they carried lye in 3kg jugs for $22.99.
Fat and lye.
Lye, or sodium hydroxide, is a key ingredient in soap making as it reacts with fats/oils to create a chemical process called saponification, which converts them into soap. This process helps to ensure that the soap is effective at cleansing by breaking down dirt and oils on the skin. Lye is essential for creating solid bars of soap that are safe and suitable for use.

Traditional soap-making processes involve using lye (sodium hydroxide or potassium hydroxide) to react with fats to create soap. However, there are now alternative methods to make soap without lye, such as melt-and-pour soap bases that have already undergone the saponification process.
lye
Lye Soap is made by combining Lye (Sodium hydroxide), Oils and water together at the right temperature and ratio as to begin saponification. Ordinary soap like in the supermarket is not this type of soap. They do not contain lye at all.
To safely mix lye and water for soap-making, always add lye to water slowly while stirring constantly. Wear protective gear like gloves and goggles, and mix in a well-ventilated area to avoid inhaling fumes. Allow the solution to cool before using it in soap-making.
The chemical reaction between water and lye in soap making is called saponification. Lye, also known as sodium hydroxide, reacts with fats or oils in the presence of water to create soap and glycerin. This process helps to break down the fats and oils into smaller molecules, which then combine to form soap. Glycerin is a byproduct of this reaction and helps to moisturize the skin.
To safely mix lye with water for soap making, always add lye to water slowly while stirring constantly. This helps prevent splashing and potential burns. Wear protective gear like gloves and goggles, and mix in a well-ventilated area to avoid inhaling fumes. Allow the mixture to cool before using it in soap making.
the only place I have been able to find some is in 1 lb containers for $5.00 at Menards. Be sure to check and make sure the bottle says 100% LYE or sodium hydroxide and nothing else.
mix lye, water, and fat in large pot. heat and stir. you will get soap.
Lye, also known as sodium hydroxide, is alkaline. It has a high pH level, typically around 13, making it a strong base. Lye is commonly used in soap making and cleaning products due to its alkaline properties.
