Does Soap Go Out of Date?

A really interesting question I have been asked is does soap go out of date?

Soap is generally considered to have an indefinite shelf life and does not typically go out of date. This is because the ingredients in soap, such as fats, oils, and lye, are not prone to spoilage. However, the scent and appearance of the soap may change over time, especially if it is scented or coloured with natural ingredients. The scent may fade or change, and natural colourants may fade or bleed over time. It's also important to note that if soap is not stored properly in a cool, dry place and is exposed to moisture or heat, it may soften or become mushy, reducing its effectiveness.

So, while soap may not technically expire, it's best to use it within a reasonable time frame and store it properly to ensure its quality and effectiveness.
