I’m revisiting some natural colorants this winter and also playing around with salt. This is the result of using salty lye water + madder tea (added to lye water) + 3% salt (added at trace) with a base that is 46% oleic (sunflower + lard), 25% CO, 25 longevity, and 2% sugar, 1.5% sodium citrate TOW. I added 2% castor over recipe TOW + 3% floral-leaning EOs when I reached the shy side of light trace. With the castor included, the SF is close to 4%. The soap was made using a 40% lye concentration.
The madder tea stock was 5 g BB madder powder steeped overnight in 100 g DI water. The water was around 180F when I added the powder. The lighter top layer of soap used .25x the madder tea in the bottom layer, with DI water added to make up the liquid weight difference in the tea.
The secret swirl, which looks less feather-like than planned, was lightened with TD. The color variation for the swirl was quite apparent when I layered the batter in the mold, but there was no sign of the swirl when I cut the soap, or on Day 2. The photo above is from this morning, a week after the soap was made. Is the swirl visible a week later because the lighter pink base soap darkened up a bit over the week? Or maybe it’s a pigment density-related effect as the soap dries? I really have no idea!.
I’m playing around with lowish salt concentrations in my regular recipes because traditional salt bars at 25%-100% salt are not producing exciting lather in the softened but high tds water at my house, even after 2-3 years of curing. As of this morning, this soap is making a dense creamy/foamy lather with some big bubbles.
