Abstract
Abstract The specification discloses a solid transparent soap employing a greater amount of sodium soap than prior artisans have ever been able to get into a transparent bar without plodding, milling or refining. In excess of 25% sodium tallow soap to as much as 55% sodium soap, based mainly on tallow, is mixed with 10% to 40% anionic or amphoteric surfactant, combinations and/or complexes thereof, and 65% to 15% of a two or six carbon dihydric alcohol. The resulting soap composition is transparent in that one can read 14 point type through a 1/4 inch bar and can be made by simple mixing, without plodding, milling or refining.
