Dawn Sci’s phenolphthalein Test solution is a unique solution for soap makers to check unreacted Sodium Hydroxide or Lye very easily. This solution does not test the pH of soap but give the instance result. It is the test preferred by professional & handcrafted soap makers because it costs less, is quicker to use, is easier to read, more accurately tests soap safety than pH strips.
How to test for Unreacted Sodium Hydroxide :
One drop will instantly reveal if soap contains unreacted or excess sodium hydroxide. If a single drop of Dawn Sci’s phenolphthalein Test Solution remains clear on the soap, then there is no excess sodium hydroxide, and the soap is safe to use.
If the drop of Dawn Sci’s phenolphthalein Test Solution quickly becomes dark fuchsia magenta, then the soap contains excess sodium hydroxide or unreacted sodium hydroxide and is not safe to use.
