NaOH vs KOH: Ratios & Discounts (Superfatting)

Świetnie wytłumaczona różnica pomiędzy NAOH a KOH.

Shaver|Soaper

Last time, we discussed the basic process of making soap, and talked about how a lye solution and fat react during the saponification process.

This time, we’re going to go beyond the basics (ha!) of lye. Remember, there are two types of lye used in soap making: sodium (NaOH) and potassium (KOH) hydroxide.

These two alkali salts, when mixed with water and added to the same fats, can produce considerably different end products. In this post, we’ll figure out the differences between NaOH and KOH, talk about ratios when mixing both, and cover superfatting/lye discounting.
