Will soap expire? Can it still be used after expiration? How long is the shelf life?

Under normal storage conditions, the storage time of soap is generally three years. Soap will be lighter, more transparent and harder if it is kept for a long time. Generally speaking, it has no obvious influence on the washing effect and can be used continuously.

However, there will be yellow and black spots on the surface of soap beyond the shelf life, and the detergency of deteriorated soap will decrease with the degree of rancidity.

Expired soap can also be used, but the effect of expired soap may not be as good as before. If you don't feel at ease, you can buy another bar of soap to clean your clothes, which will make them cleaner. When washing expired soap, check whether there is foam, and if there is, you can continue to use it.

I hope my answer is helpful to you. I hope it can be adopted. Thank you.
