Q.Can Shea Butter Expire?
Yes, shea butter can expire. This can only happen though after a long time. That is because shea butter in its raw, unrefined form has a shelf life of about 12 to 24 months. It gets better with the fact that you can easily maximize your shea butter’s shelf life. All you need to do is store it under the right conditions as explained below.
Always keep your raw, unrefined shea butter in a cool, dry place. Preferably below 55 degrees F. Direct sunlight is also bad for your shea butter, so store it in a dark place away from direct sunlight or heat. You can of course heat shea butter to melt it before use. But when doing this, be keen not to overheat it. Scoop just a little to prevent it from melting repeatedly. Heat can easily make your shea butter go rancid. So avoid leaving your shea in the car with all the windows closed or in any other place with a lot of heat.
Then contrary to what many people believe, mixing old shea butter with fresh shea butter is a bad idea. This will only spoil your sheer butter and shorten its lifespan. You can however use recommended natural preservatives like rosemary or vitamin E. The preservatives may increase shea butter’s shelf life but only for a few months. Then note that any impurity added to shea butter may make it ineffective. This means that you do not have to add anything to it at all. Just store it under the right conditions.
