batter color - less yellow?

[GuacamoleSalad]

I made what was meant to be a purple/white ombre the other day and had a difficult time getting my white batter white. Some of that was an issue with undispersed titanium dioxide but I think my soap was also just extra yellow. Too much olive oil?

35% olive oil
33% palm oil
20% coconut oil
7% shea butter
5% castor oil

If you are using virgin OO, switch to regular OO. If your using unrefined shea, it can cause yellow too

Ah, that makes sense. Thank you!

Lard or tallow usually results in a whiter soap. You might try switching the olive oil to rice bran oil.

Thank you. Lard isn't going to work for me but I do intend to get tallow in my life at some point, and I'll put rice bran oil on the list.

I use RBO in my soaps and I find that my RBO recipes tend towards yellow. I am in the process of replacing my RBO for a "whiter" oil like Sunflower/Canola. I do like the feel of RBO in my soaps but prefer a naturally white soap so I don't have to TD it so much.

Looking at the recipe, palm could contribute to slight yellowness. Depending on how yellow it originally was. I'm not sure there is a lighter coloured RBO available. Not in my area at least.

I compared my soaps with the same recipe (CO, PO, OP) but with RBO swapped for Lard. Purple one is with 10% Lard while the blue one is with 10% RBO. Both had TD added to whiten. The blue is obviously leaning towards green due to RBO.

RBO is very yellow compared to the OO I use. I use 20% of each - so that's more than your 35%. Definitely switch from Extra Virgin if that's what you are using - it's expensive and not needed for soap. Aside from that all other oils/fats I use, but for 5% avocado, are very white. Yes my batter is a bit yellow, but even without TD it does cure out to a creamy white colour. Also consider things like yellowing FOs and water alternatives such as aloe juice - as they can contribute to yellow soap.
