Is it possible for soaps to improve with age?

[wimbouman]

A question for the shaving soap connoisseurs here.

I recently noticed a real improvement in two of my soaps.

The first one is a Portland General soap. I did like it when I bought it, but was not blown away by its lather.
Last week I took it back in the rotation and found the lather to be thicker, creamier, less bubbly and easier to make.

So, that could have to do with my improving skills if it weren't for the same experience with some Nana June's.
Also bought these like year ago, ,and did like the Coconut (a lot) whereas the Moroccan Mint did not work for me.
Triggered by the Portland, I tried it now and it is so much better.

So, is it me or is it possible for soaps to improve with age?

Thanks for your thoughts on this!

i am in no way an expert but have some chemistry knowlege, and think it's because your water provider might be sending you softer water

i can't see the soap changing over time by itself (or you could 've just gotten better at lathering)

I am no expert either but I do know soap has to cure or age a little after making it. I honestly have to admit I don't have a clue about how long that takes. I had the same experience with both Cella and P.160 though; after leaving it used in a bowl for a couple of months the lather was richer and even easier to make.

Another thing is going on with really hard soaps; there seems to be an extra hard top layer that has to wear off before it lathers as it should.

Interesting, but I don't think so...it's not wine

I think that your lathering technique has improved and/or (as suggested) your water quality changed.

If the soaps is a cold process one, the extra time may have allowed it to further cure, which allows the lye and oils to fully complete their chemical changes and any extra water to evaporate. Of course, this will not turn Williams into Yardley or anything, but it can make a difference.

Thanks, Matthew!

I'll see if I can find out if these are cold process.
The water evaporation certainly could be a factor.

Thanks!
Seems to fit my observation perfectly.

I shall see if all my jars have dates and watch them closely.

Eyebright is 100% correct, but be aware that the chance of a quality soap (bath, shaving, etc.) going rancid is fairly rare. It does happen, but I would not be too worried.

In my opinion, expiration dates are a conspiratorial hoax, but that is an argument for another time. You would be better served by just using your nose.
