Item Tested: Soap
Predictions/Comments: We've all been blessed with the bitter taste of soap at least once in our lifetime, so we guessed it would be a base.
Safety: Avoid having this substance enter the eye or being swallowed. It may sting, irritate or swell the eye or irritate and dry the throat. If such situation occurs, rinse eye with water or drink lots of water.


Conclusion: The resulting colour was a red-purple colour, so this soap is acidic. We were confused so we did some product research and found that this soap contains citric acid.
