100% Olive Oil, made with Virgin Olive Oil, very gentle on the skin.  Castile soap needs to stay dry for longevity.  It gets harder over time. Sometimes it is best after having cured after 1 year, but it is fine to use after 6 weeks of curing time! 

Preserving Your Soaps Shelf-Life

1. Keep stored in cool, dark areas free of moisture.

2. Once opened, start to use immediately.

3. Do not risk it – toss out any soap with mold.

4. Use natural soaps first, as they will expire before commercial soaps.

5. Preferably, buy shrink-wrapped soap bars.
