I believe that the consumer should know exactly everything that is in a product, whether it is regarded as safe by the powers that be in charge of such things or not.
I also believe that if an ingredient used to make a product is changed by a chemical reaction, then it is not important to list it, since it is no longer present in the end result. It is important to list the end result because that is what we have. Some people can be harmed by even traces of certain substances-such as nut traces. It is important to make it clear about whether or not the possibility of nut traces exist for a product, and thankfully, this is included in product labeling. Sometimes I forget to list purified water as an ingredient on my soap labels when in fact there is a trace amount of water left in the finished soap-especially a freshly made soap-ugh! I don't mean to do that! It violates my principle of stating exactly what is in the soap! I do apologize for this, and rest assured-this is the only ingredient in a finished soap or other creation that I forget to list. I think it happens because I consider that trace amount of water to be truly extraneous. Purified water truly is harmless, isn't it?
Another thing that I do not usually do is list my ingredients by their fancy scientific names. I can-but-I just don't want to. I want to list ingredients in easily interpreted language. I don't think spicing up my labels with inflated language and technical terms does anything to enhance the quality of the product. it's already good, or I wouldn't offer it. I do love addressing my plants by their scientific names when I'm out puttering with them-but I'm not going to inflict this on everyone! I also won't say anything about a soap or other product that isn't absolutely proven. I can't say that certain substances are definitely good for wrinkles, skin tone, etc. I do mention what substances have been historically used for in folk medicine, or metaphysical references, and sometimes aroma-therapeutic references, but I cannot assert vehemently that the substances absolutely worked for whatever uses they were put to. I believe whimsy is O.K. for amusement and that truth is more important than increasing sales.
