Which fats produce slow-lathering soaps that clean well and are mild on skin?

Hard fats that yield slow-lathering soaps include tallow, garbage greases, hydrogenated high-melting-point marine and vegetable oils, and palm oil.

These specific fats produce soaps that are mild on the skin and cleanse well, though they produce little lather in cold water and more in warm water. Tallow is the most important member of this group and serves as a primary raw material in the international soap industry.1
