Some of you might be wondering, "Lye? Isn’t lye dangerous? Won’t it harm my skin?”
First - all actual soap is made with lye. No lye, no soap. (A lot of "soap products" in the stores are actually detergent. If you look at the labels, they are not called "soap". They are called "hand wash" or "body cleanser" or some such thing.)
This could become a chemistry lesson, but to make it short - soap is made from lye, fats and liquid. When the lye mixes with the fats and liquid, some kind of chemical reaction goes on, and the lye and fats change into soap and glycerin. In the process, the lye is all used up. Even though lye is used to make the soap, there is no lye left in the soap at all.
This is why soap made with lye is not dangerous, and it definitely won’t hurt your skin.
Let's talk about Titanium Dioxide - I mean, that sounds like some kind of weird chemical, doesn't it?
Titanium Dioxide is a type of metal oxide. Metal oxides make up most of the earth's crust and are formed with metals react with oxygen from the air or water.
It's a natural substance. And it also happens to make whiter soap.
Red Iron Oxide is another metal oxide - it's a colour that is used a lot, including by the pharmaceutical industry, in cosmetics and in soap.
