Saint Agnes Soap Unscented contains absolutely no preservatives, parabens or additives. Totally natural.
The scented mini bars have essential oils in them for fragrance.
There are organic essential oils which do not contain any chemicals. Then there are the 100% pure essential oils, again, no chemicals. Then, there are the more mainstream essential oil compositions that may contain chemicals.
I will label which minibars are scented organic, 100% pure but not organic, those which are mainstream.
Ingredients listed on verso of each bar, for your ease of reference.
