Can Soap Expire?


The question on when soap expires has always been tricky. First, it is important to understand that commercial soaps come in large batches. Therefore they are not created with the same care and attention as homemade soap. Second, because the batches are so large, and because it is for large scale retail. Companies often have to use certain chemicals to make their product stretch longer. Because of this, in the case of soaps, the question of “does soap expire” is yes.

Commercial soaps can expire because age can alter the chemical composition of the soap. The truth is, manufacturers print earlier expiration dates for safety reasons. They don’t want to risk people using their product when it is no longer safe. So they will usually give a date six months or more prior to the actual expiration of the product.

Does Soap Expire: Key Points

  • Soaps with harsh chemicals are more prone to expire
  • Once your soap is expired it becomes very dangerous to use it.
  • Soaps last for around 2-3 years
  • All Natural Soap is less likely to expire so soon.

The Dangers of Using Expired Soap

Expired soap allows for the bacteria to grow rapidly and dangerously. The fats and essential oils have faded in potency. Which means using the soap could cause rashes, skin irritation, dry skin, sensitive skin or even a skin infection. It is important not to keep your same bar for too long. Even if you don’t think you have had it for that long, if you are experiencing any dryness from your commercial soaps, toss it.

When it comes to all natural handmade soaps, the story is different.

Whether or not your soap expires depends on the ingredients.

The first ingredient: real soap made from lye and fatty acid never expires

The second ingredient is super fat. How long handmade soap will last depends on how much fat you put into it. When you add fat to soap, you lessen its longevity due to the oxidation reaction.

Capulet soaps puts more natural oils and butters in our soap than fat to increase its shower shelf life. Which has an equal effect on your skin.

In the soap production, you need to keep superfat or an equal substitute in the soap which are the ingredients that benefit skin the most. The best way to make soap that will last a long time is to make sure to mix the fats, oils and butters are very well. Also, the un-saponifiable ingredients you put into a soap can affect its expiration. Adding organic herbs, flowers, bits of fruit, etc, can shorten your soap’s shelf life simply because these things do not last long.

The moisture in Herbs, Flowers, and bits of fruit is likely to mold or rot if the plant or fruit is not dried before putting it into the soap.

Wrapping Up: Does Soap Expire?

As a rule of thumb, handmade soap that is well made like Capulet Soaps should last about two to three years before it is potentially irritating to the skin. Be sure that you cured your soap completely, and once the curing process is complete, store in a cool dry place that has some ventilation. Storing in an airtight container will not be good for the soap because it can sweat.

When asking yourself “does soap expire,” consider what the soap looks like. Does it look moldy? Smell bad? If it doesn’t look or smell right, you are better off not using it if any of these apply.
