I am not intimidated by the name Lye. I am aware of what you state above, and it is correct. I had at one time thought of suggesting that sodium hydroxide could be used as well as baking soda for neutralizing aloe vera when you add CS, but decided not to for two reasons. First, the possibility of getting lye directly on the skin while preparation would cause burns, and second, if too much was used, the final mix would be caustic. Baking soda is self limiting in this respect and thus much safer. Anyone that read ingredients like I do, would know that sodium hydroxide shows up many places, especially in many toiletries, such as shampoo. It is also a major component in many soaps.
