I have to admit that this is really old news, but I am sure that most people have not heard this story and I wanted to share this great video. The video below explains how real soap tests positive (false-positive that is!) for the date rape drug. This is simply a problem with the drug testing kit, but it turns out to be a great way to find out if what you are using is indeed real soap and not a mixture of synthetic detergents. Their are many cases of products being mislabeled and claiming to be soap when they are in fact detergent. While this test is a pretty cool trick for us soapmakers, I am sure most people will not want to check their soap with a drug kit to determine if it is really soap. An easier way to determine what is in your product is to look at the labels. Be on the look out for "soaps" that have Sodium Laureth Sulfate, Sodium Lauryl Sulfate, Ammonium Lauryl Sulfate, Ammonium Laureth Sulfate, or Cocomidopropyl Betaine as these are all common detergents used in soap-like products. On the other hand, if the label lists oils and sodium hydroxide or potassium hydroxide as the ingredients, then you have real soap. I should note that real soap and detergent products can be found in both solid (bar) and liquid forms.
Check out the video below and at the very end you will see a list of companies that are falsely advertizing their product as soap. As a consumer, you should be able to make an educated choice about what products you are putting on your body.
