The seal is on the front panel of the bottle in black (the rest of the label being in blue). Unless I need to find my glasses.
So for Dr. Bronner's to legally use the USDA seal, they have to be a minimum of 95% organic. Which means no more than 5% is lye + citric acid + tocopherol. For the sake of argument, I'm just going to assume that the whole 5% is lye and ignore the other two ingredients. I've been running some scenarios, and trying to give them the benefit of the doubt but I am hindered a bit by the fact that I've never made liquid soap. Here's what I've come up with, if someone more experienced could take it from here??
I made the following assumptions in order to stack the cards in their favor:
*20% SF (what is the high end for SF in liquid soaps?)
*I input as much jojoba as possible because it has the lowest SAP value, while keeping all the oils in their proper weight order in relation to each other and to the location of the lye on the label.
*I did NOT check the 90% KOH box as that raises the lye amount a bit.
In order for the lye to be 5% or less of the total, that total needs to be 52.8 ounces (2.64/.05). Subtract the 16 ounces of oils and the 6.08 ounces of grape juice substituted for the water leaves 30.72 ounces that would need to be included in the recipe. I see Shikakai powder on the label, and it would have to fall between the olive and hemp oils, so that's 2.64 ounces, still leaving 28.08 ounces unaccounted for. The first ingredient on the label is sucrose, so it has to weigh more than the 4.16 ounces of coconut oil I came up with. How much sugar is it reasonable to add to a liquid soap? Certainly not 28.08 ounces... But again, I'm running numbers having never made liquid soap myself. My guess is that you need to add far more than the recommended 6.08 ounces of grape juice, and that the tocopherol is the preservative needed for all that liquid. Is it possible we are looking at perhaps 5 ounces of sucrose and 23 additional ounces of juice (for a total of 29 ounces liquid)?
I hope that's the case. If that's just way out of the ballpark for a liquid soap, then I have one other possible scenario but I don't like it. It might be legal, but it would certainly be an abuse of the process. What if they start with a massive amount of sucrose and grape juice, and that they reduce the mixture by cooking it down before actually making the soap. If that was reduced by half it would be like using syrup instead of water, but I think it would still work.
I love science when I have the answers. This is slightly less fun. :?
