Documented Uses

Used in high-pressure lubricants and varnish driers; [Merck Index]
Octadecanoic acid, lead(2+) salt (2:1): ACTIVE
10 to 30 grams for and adult human (lead salts). (T17)
Lead is absorbed following inhalation, oral, and dermal exposure. It is then distributed mainly to the bones and red blood cells. In the blood lead may be found bound to serum albumin or the metal-binding protein metallothionein. Organic lead is metabolized by cytochrome P-450 enzymes, whereas inorganic lead forms complexes with delta-aminolevulinic acid dehydratase. Lead is excreted mainly in the urine and faeces. (L136)
