Colour of soap

by Wendy
(New Zealand)

My soap that I poured into moulds went white, ( as it did in a previous batch) and then went a dark honey color, I used a stick whizz to mix, but I did this outside, also the temps were both 38c.

Don't know what went wrong, also I left them outside in the sun, with glad wrap tightly covering them, maybe this was a mistake, but they started out great and went white as they should of... any help would be appreciated... thanks.

Answer:

Do you mean that when you poured the soap into the soap mold it was white and when you unmolded the soap it turned out to be a dark honey colour?...

or

Do you mean the bars were white and then you wrapped them tightly in cling film, left them in the sun and then they turned a dark honey colour?

If it is the first option, you will find that the ingredients you add to a batch of soap will often discolour the soap. For instance, any soap with milk in it can turn anywhere from a light cream to a deep brown colour...even orange in some cases. Many fragrance and essential oils will also discolour the soap.

If it is the second option, it's probably not a good idea to leave the soap sitting in the hot sun and though I haven't done it, I imagine it could discolour the the finished soap bars.
