2. Eye irritation testing

Test conditions

Animal Japanese white rabbit
Sample DM-FLUID-5cs

Test results
Absolutely no effect on the cornea or iris. There is slight inflammation of the conjunctiva, but to a far lower degree than that caused by typical detergents.

3. Acute toxicity test*

Test conditions

Animal rat
Sample DM-FLUID-5cs

Test results
LD50 is over 5,000 mg/kg for both males and females.


*Acute toxicity test
Generally speaking, this test determines the amount of a substance that constitutes a lethal dose when administered at one time to a test animal.
It is usually expressed as "LD50" (50% Lethal Dose).
Please refer to the following table of degree of toxicity.

Classification based on strength of toxicity

Degree of toxicity* Oral LD50 (rat)
(unit: mg/kg)
Very toxic ≤25
Toxic 25-200
Harmful 200-2000
