I don't know about the aloe, but I've decided to add the sugar and sodium citrate to the additional water required for the 50% lye solution. Adding anything else but water and lye will change the math from almost foolproof to quite complicated. It's just not worth the trouble to me.
For that matter, using citric acid instead of reacted sodium citrate will change things a bit, too. If you're using the 6g to 10g ratios to account for the citric acid, you're actually going to be adding more water in solution along with your extra lye. You can obviously figure it out, but I'm not looking for additional complications on soaping day.
