White crystals on cold process soap

[Inde]

Hi Soaping friends, I made this milk soap super fatted to 5 % with
lye 34.33 gram
milk 90.75 gm
castor oil - 25 gm
mango butter - 50 gm
rice bran oil - 100gm
sunflower oil - 100 gm
I was out on vacation for 2 weeks and saw this on the soap on return. There are white crystals all over the soap. What could be the reason, Please help

Probably soda ash which is harmless.

I would guess soda ash, also. Wipe them off with a damp cloth and then do a zap test. If you don't get zapped, then it was probably ash.

First, that's most likely soda ash.

Second, that batch size is too small. If you have a typical kitchen scale precise to the single gram, you should make at least a 500g (of oil) batch to minimize the impact of the imprecision.
