And phenolpthalein drops ... well, don't get me started on them.
So if there is no water between phenolphthalein and NaOH then this indicator works well with the above test. I did the test my own where I had two cups, one with few NaOH pellets and the other with ammonium powder. Phenolphthalein turned pink on the NaOH pellets, so I guess someone that dislikes licking soaps while searching for excess lye spots on soaps, then this could be an alternative test.When you open the cup the next day, the soap should appear normal, but if you have made it correctly it will be lye heavy. To see this, dribble a few drops of phenolphthalein indicator onto the soap. It should turn pink. Be aware that phenolphthalein is most often sold as a solution in alcohol, and this is what is needed for the test. A solution in water will turn pink whether or not the soap is lye heavy.
As she was talking about testing for pH, her comment still stands - it is not a good way of determining the pH of a soap.
As for use in general as a zap-alternative, while in that particular case it would show that the soap was lye heavy, I understand that it can also turn pink with non-lye heavy but high pH soaps, giving false positives
Not nearly as dangerous as not knowing what you are talking about.How disgusting! Non scientific methods of testing soap for lye is dangerous.

Greetings,
So...not a good way to start I know. But, I did the Zap test and sure enough I felt the sting, much like I do when I see George Clooney. My soap looks really pretty, I'm really shocked but I worry about it being unsafe to use. They have been curing for almost two weeks and I still got zapped. If I let them sit for 8 weeks and beyond (whatever it takes so long as I don't have to rebatch ...which I don't even know what that means. I certainly don't want to have to toss it or make laundry soap of it cause, well, I don't have a clue how to do that either. Any input from you sweet soapers would be greatly appreciated.[/SIZE]
