Results and discussion
- Preliminary study:
- There is no indication from the skin irritation tests conducted that this material is absorbed through the skin in toxic amounts.
- Mortality:
- None reported
- Clinical signs:
- undiluted - intact skin - 10 applications to the belly: Slight hyperemia throughout experiment - slight edema persisted after 4th application.
undiluted -abraded skin - 3 applications to the belly: Slight to moderate hyperemia with slight edema after each application - moderate necrosis followed 3rd application - skin healed with slight scar in 21days.
10% aqueous solution - intact skin - 10 applications to the ear: Slight hyperemia after 3rd and 4th applications only.
10% aqueous solution - intact skin - 10 applications to the belly: Slight hyperemia after 2nd, 3rd and 4th applications only.
10% aqueous solution - abraded skin - 3 applications to the belly: Hyperemia during 1st 4 days of experiment only - skin essentially normal in 14 days. - Body weight:
