I have a speech in school to convince people to do something . I am trying to convince people to shave with a straight razor over a disposable. I am planning on comparing ingredients of shaving cream. I am looking at a can of Gillette, and some of the ingredients are isobutane, propane, butane, hydorxethylcellulose, triethanolamine, triethanomine, and quaterniu-15. Does anyone know the main ingredients of Mama Bear's soaps? I don't need any trade secrets, I just want a comparison of the two. It also seems that the two have different purposes. The gillette seems to be made more to prevent your razor from clogging, while the Mother Bears seems more effective at lubricating your beard, and skin, making shaving more effective. Am I wrong? I was also planning on comparing waste produced, overall cost, and effectiveness. If you have another reason to support straight razor shaving, I would love to hear it. Thanks.
