Architect White Soap - Ultimate Luxury Bar

I love this recipe. Completed 2/29/26 and 03/01/26

Start with hand mixing, then emulsion blending only in pulses in short bursts, 30 seconds waiting to ensure not separating for false trace. It was a pretty white in fridge 9 hours later. Then need to let it sit out of fridge for about 24-48 hours, then don’t use for 10 weeks min, 12 weeks (3 months!) ideally!

• Hard Fats (120°F)

• Tallow, 400g, Melt to 120–130°F

• Cocoa Butter, 50g

  • (Keep below 125°F, but takes longer to melt, so add before shea), reheat as necessary to fully melt

• Shea Butter, 150g, (Keep below 125°F) 

• Shea can get grainy if overheated repeatedly

• While this is heating/cooling, can work on Lye mixture (129g Lye, 263g water)

• Let this cool to 95–105°F (will take 45 minutes or so)

• Remove oils from heat once melted, then at around 115°F, add:

• Olive oil, 250g

• Coconut Oil, 100g

• Castor oil, 50g 

• (reserve a couple spoonfuls, unheated of this for the goats milk, if using)

• Cool whole batch to 105–110°F

• Add goats milk, 25g into some of the oils from above

• Scoop a small amount of warm oils (a few spoon full), and mix in powdered Goat Milk Powder (If Using). Fully mix in before adding to main batch. (Wait to add until all temperatures are lined up. 

• If need to reheat other batch to match lye temp, less chance of burning the goats milk. 

• Once goats milk is added to main mixture, stick blend briefly to fully disperse.

• Blend oils and lye when 

• Oils are 105–110°F

• Lye is 95–105°F

Mixing notes:

• Pour lye slowly into oils. (snow falling onto a lake to prevent splashing)

• Hand stir 60–90 seconds.

• Stick blend in short bursts until emulsion only.

• Wait 30 seconds to see if separates to know if reached perfect mixture. 

• Target batter temp at emulsion 95–105°F

After Pour

• Into fridge within 5–10 minutes

• 8–12 hrs (12–18 if milk)

• Remove

• Sit at room temp 12–24 hrs

• Unmold at 24–48 hrs

Engineer Notes

• Hard fats fully melted = prevents false trace

• Combine above 95°F = prevents stearic thickening

• No gel = whiter, slower initial firmness

• 33% lye concentration = sharper edges

ARCHITECT WHITE – FORMULA TABLE

(8% superfat, 33% lye concentration)

Notes on Unmolding: This was still mushy soft after fridge 9 hours. Do not panic! It hardens with time.

On color: I even added the goats milk at 110 temp ideal, then had to warm the whole thing, accidentally to 150, and it went a little yellow, but after adding lye and everything, had good timing to pour. 2/27/26
