Adding sugar to goat milk soap recipe

[SoapSisters]

I'd like to use sugar instead of castor oil for bubbles (I've run out of castor and will only have some in a few weeks) in goat milk soap. I'd like to use GM for 100% of the liquid in my soap, if possible. The issue is that I use frozen goat milk and can't figure out where/when to add the sugar. (I know that with water, the sugar should be dissolved first, before adding lye.)

Should I melt just a little bit of GM, just enough to dissolve the sugar in, before adding my lye? Can I melt the sugar in my oils? (As an aside: would honey have a bubbling effect also?) Is there no way around using a bit a distilled water to dissolve the sugar?

I'd appreciate any and all advice!

I'd be worried about overheating. GM, as well as cow's milk, already has natural sugars and can overheat if you're not careful. I don't think I would bother adding sugar.

Do a seasrch on here, there are a bunch of topics on sugar and milks.

I too say heat will be an issue.... you can melt it in the milk and then freeze it

Sugar is water soluble, but it's not fat soluble. You have to dissolve it in a water-based liquid -- use some water or liquid milk.

Some people who use sugar a lot in their soap have gone to using simple syrup made with half water and half sugar.

I tend to agree, however, than the sugars in the milk are probably enough without adding extra sugar.

Kevin Dunn (author of Scientific Soapmaking) did a study that showed the sugars consume some lye. He found fluid goat milk consumed roughly 4% of the lye (in other words, goat milk added 4% to the superfat compared with water). The milk fat consumed some of the lye, as expected, but Dunn also showed that the lye also reacted with the sugars (lactose) in the milk.

According to my estimates, using full-fat cow milk as a complete replacement for water will raise the superfat by roughly 1%. If this trend holds true for goat milk, then sugars in milk add at least half of the 4% superfat.

If you decide to add some sugar maybe you could dissolve it into the goats milk before you freeze the milk. I haven’t tried it though.

I dont see why you should need sugar with the GM, I do HP and it helps with fluidity along with SL but if I were doing a straight CP GM soap I wouldn't add sugar personally as some sugar is present in the milk, plus it would really add to the heat up IMO and could potentially be a scorcher!

Thanks, everyone! I think I'll skip the sugar!
