What does the 72% soap base mean and how does it affect performance?

The 72% marking indicates that 72% of the bar's weight consists of actual soap base material, meaning it is a concentrated formula with less water and fillers compared to lower-grade soaps. This higher concentration translates to more surfactant content per gram, so you need less product to achieve the same cleaning effect. The soap base is formed through saponification of animal fats (sodium tallowate) and plant oils (sodium cocoate and sodium palmitate), which creates the cleansing molecules that lift grease and dirt away.

Because it is a harder, more concentrated bar, it tends to last longer and produces a stable lather when worked between wet hands or on a washboard. The solid form also means it can be easily grated or dissolved for making liquid solutions if you prefer, though it works well directly on fabrics or surfaces. The high soap content makes it particularly effective for tasks where you need reliable grease-cutting power without added fragrances or softening agents.
