Gall soap
Gall soap is a soap product made from curd soap and beef bile . It is available as a solid or liquid end product and is an old home remedy for treating stains in textiles .
The washing effect of beef bile is based on the emulsifying properties of the salts of bile acids contained therein , for example glycocholic acid and taurocholic acid . Washing-active enzymes are practically non-existent in the bile. Gall soap is effective against many types of dirt, but especially against stains caused by fats , starch , blood , fruit (vegetable colors) and protein . To remove stains, the affected area is moistened, rubbed in vigorously with a piece of gall soap and then washed out or washed in the washing machine as usual without washing out beforehand.
