Fragrance is evil
This is just my personal opinion of course, but all of my soap and lip balm products are fragrance free. Why? Certain fragrances give me debilitating migranes, others give me hives. Life is just not fun when you are itchy, in pain and nauseous and I do my best to live a fragrance free lifestyle. This also includes avoiding people who douse themselves in so much perfume/aftershave that you can taste them in the air after they have walked away! Since I don’t want to be my own personal test bunny to work out what smells don’t affect me, I choose to have no smells whatsoever.
There are of course other reasons why I don’t like fragrances and essential oils. Some of these products are problematic, they may be chemically undefined e.g. essential oils often consist of hundreds of different molecules, most of which we don’t know the safety profile of, which is concerning as some essential oils are toxic to cats and dogs. Other fragrances are suspected of being endocrine (hormone) disruptors in the scientific literature and no-one wants to unintentionally develop man boobs. But each to their own and I will be selfish and say I just want to live a migraine free life as much as possible and that is why all of the soap that I make will be fragrance free.
