| A relative of mine worked in a chemical factory in Detroit, that
| made lubricants for metal working. Many of them were either
| formulated directly from tallow and lard, or were soaps. The
| materials were cheap, they worked, and were considered to be
| relatively non-toxic.
|
| One thing I've noticed is that detergent based "soap" has

| detergent bars that contained no soap. They also didn't produce
| soap scum in hard water areas. Remember, "You're not really clean
| until you're Zestfully clean." Well, Zest was a detergent bar.
|
| Today, looking for detergent "soap" at the store, it's gone. Even
| Zest is made from lard or tallow, last time I looked at the
| ingredients. I've banned soap from my house because I hate
| cleaning up the soap scum. We use liquid body wash instead.

|
