11. Toxicological information
Acute toxicity (oral)Harmful if swallowed
rat LD50=805mg/kg (70% H2O2)

Acute toxicity (dermal)

Harmful in contact with skinrabbit LD50=690mg/kg (90% H2O2)

Acute toxicity (inhalation)

Harmful if inhaled
Vapor : rat LC50=4108ppm/4h (35% H2O2)
Mist : mouse LC50=0.46-1.00mg/L/4h (90% H2O2)Skin corrosion/irritation

Causes severe skin burns
The conclusion with necrosis which penetrates to all layers of the skin or corrosivity is
indicated in 3-minute, 1-hour, or 4-hour application on rabbits. Thus, it was classified into
category 1B.

Serious eye damage/irritation

Causes serious eye damage
The product is a skin corrosive substance. There is a publication that it shows severe
irritation in animals and it is corrosive. Based on the above information, it was classified
into category 1.

Carcinogenicity

Suspected of causing cancer
ACGIH classifies it as the group A3(confirmed animal carcinogen with unknown
relevance to humans).

Specific target organ toxicity(single exposure)

Causes damage to organs (respirator organs)
The irritations to the nose, the throat, and the tracheal are reported in humans andanimals(rat, mouse). In animals(rat, mouse), there are the descriptions that it causes thecongestion, pneumonedema, emphysema of lung and tracheal and necrosis of tractepithelium within the dosage (0.34-0.43 mg/L) of the guidance level of category 1. Basedon these results, it was classified into category 1 (respiratory organs).

Specific target organ toxicity(repeated exposure)

Causes damage to organs (respiratory organs) through prolonged or repeated exposure
In the inhalation test of vapor in dogs and rats, fibrous tissues appear here and there inpneumoconiosis with the dosage (0.005-0.01 mg/L) of guidance value range of category 1,
and there was the statement that mixture of atelectatic lung area and emphysema area(dogs), and necrosis and inflammation in nasal epithelium and cell infiltration in larynx(rats) are seen and it has irritation in nose, throat in humans and there is a risk ofdeveloping pulmonary edema in the worst case. Thus, it was classified into category
1 (respiratory organs).

Aquatic environmental
hazards (chronic)

No classification

Persistence and degradability

Readily biodegradable

Biological accumulation

Low residualibity
Generally it is said that hydrogen peroxide is readily decomposed by a catabolic enzyme,catalase.

Hazardous to the ozone layer

No classification

Other adverse effects

Flow of hydrogen peroxide into activated sludge facilities results in extinction ofmicroorganisms (activated sludge) or in weakening their action. Accordingly, it may
lower treatment efficiency of facilities or make them inefficient.
When it flows into public water areas, it will affect pH and COD of the regulated standard
items, depending on the amount.

13. Disposal Considerations
Disposal method forresidual waste

Dispose of the residual waste according to the related laws and regulations and related
local rules.
Request waste treatment to the permitted company or local public agency if any.

Disposal methodSmall volume

Dilute fully with a large volume of water.

Large volume

1. Lead to a safe place such as a pit.
2. Dilute with water until concentration of hydrogen peroxide reaches about 3-5%.
3. Add a reducing agent such as sodium sulfite, metals, catalase or the like to slowly
decompose hydrogen peroxide.
4. Dispose the waste in comply with local laws and regulations.

Disposal method for polluted
container and package

Containers and bottles to be used should be re-used with clean conditions or disposed
properly in accordance with national and local laws and regulations. When disposed theempty containers, empty the contents completely.
