Usage: One drop will instantly reveal if soap contains unreacted or excess sodium hydroxide. If a single drop of 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 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.
