Does brush soap (pink soap) go bad or expire?

[books-to-the-sky]

I have a small bottle of Mona Lisa Pink Soap that's over 1 year old and has been stored in fluctuating temperatures (between around 25°C to 35°C, or 77°F to 95°F). Do you think it would still work okay? Or might it have 'gone bad' with some kind of chemical change by this point?

Never heard of soap going bad.
My brush soap is 6-7 years old and still going strong.

I live in a desert and my brush soap experiences wild changes in temperature (30 degrees or so of variation) and i have had no issues with it over the last 10 years.

Ok, great! Thank you very much, Dragonsreach and ozymandias, for the information/voices of experience! I just found the bottle stashed in a forgotten box so I was worried about using it, but I am now reassured.
