１１．TOXICOLOGICAL INFORMATION
Acute toxicity
Product：No data
Silica, amorphous 3160mg/kg Oral rat (LD50) RTECS
BHT
2450mg/kg Oral rat (LD50) published data by nite
BHT
> 2000mg/kg Transdermal rat (LD50) published data by nite
BHT Oral
There are 5 reports on rat LD50 values (890 mg / kg (Ministry of the Environment Risk
Assessment Volume 6 (2008)), 1,700-1,900 mg / kg (DFGOT vol.23 (2007)), 2,450 mg/kg(DFGOT vol). .23 (2007)), 2,930mg / kg (SIDS (2002)),> 10,000mg / kg (SIDS (2002)),
but 890mg / kg (Ministry of the Environment Risk Assessment Volume 6 (2008)) is
detailed Since it is unknown, it was rejected, and 3 out of 4 cases did not fall under theapplicable category.
BHT transdermal
The rat LD50 value was> 2,000 mg / kg, and it was excluded from the classification
because it was reported that administration of 2,000 mg / kg resulted in death and no
toxic symptoms (SIDS (2002)). It was not classified as a category.
Skin corrosion/Irritation
Product：No data
BHT
There is a description that there is very mild irritation in the rabbit occlusion
application test, and there is a description that there is mild irritation in humans(SIDS (2002)). It was not classified as a category.
Serious Eye damage/Eye Irritation
Product：No data
BHT
In the Draize test using rabbits, 6/6 cases of mild inflammation of the conjunctiva wereobserved 24 hours after application of this substance 100 mg, but it was completely
recovered after 72 hours (SIDS (2002)). It was classified as Category 2B.
Skin sensitization
Product：No data
BHT Skin sensitization
Classification is not possible due to lack of data. SIDS (2002) and IUCLID (2000) havenegative data in guinea pig tests, but SIDS (2002) has limited data.
Regarding humans, SIDS (2002) found that all patch tests conducted on a large
number of workers and patients were negative, but it cannot be judged that thissubstance is completely sensitizable. There is.
Germ cell mutagenicity
Product：No data
BHT
In vivo, all of the mouse reciprocal translocation test, mouse and rat dominant lethality
test, mouse specific sitting test, mouse bone marrow cell micronucleus test, and mouseand rat bone marrow cell chromosomal aberration test were negative (Ministry of theEnvironment). There is a report of Risk Assessment Volume 6 (2008), SIDS (2002)).
In vitro, the gene mutation test of cultured mammalian cells showed positive findings
in cytotoxic concentration, but the bacterial return mutation test was negative, and thein vitro chromosomal aberration test showed some positive findings. (Ministry of theEnvironment Risk Assessment Volume 6 (2008), SIDS (2002), ACGIH (7th, 2001), NTP
DB (2013)). It was classified as not classifiable.
Carcinogenicity
Product：No data
Silica and amorphous
IARC group 3 (not classifiable as to its carcinogenicity to humans)

Kaishitukun、MAEDAKOSEN CO.,LTD.、0509-01、Feb.02,2022、6/9

BHT
Since it is classified into Group 3 (IARC40 (1987)) by IARC and A4 (ACGIH (1995)) by
ACGIH, it cannot be classified.
Reproductive toxicity
Product：No data
BHT
Reproductive developmental toxicity was not observed in each generation in the 3rd
generation study in which mice were fed by diet, but in the 2nd generation study inwhich rats were fed by diet, a decrease in the number of littermates was observed at adose that did not show general toxicity in F0. (SIDS (2002)).
Oral administration to pregnant mice and rats does not cause developmental toxicity,
but only delayed ossification in the fetus at doses that are markedly toxic to the mother(mortality rate of 10% or higher) (SIDS (2002)). )). Therefore, this substance is notconsidered to cause developmental toxicity.
Regarding the effect on fertility, it was classified as Category 2 because it was observedin rats but not in mice.
Specific target organ toxicity （Single exposure）
Product：No data
BHT
Two women who took 4g or 80g of this substance had upper gastric spasm, nausea,
vomiting, fatigue, and neurological symptoms (SIDS (2002)), ACGIH (7th, 2001),
abdominal pain when taken orally by humans. It was classified into Category 1(nervous system) from the description that it causes confusion, dizziness, nausea, andvomiting (Ministry of the Environment Risk Assessment Volume 6 (2008)).
Specific target organ toxicity （Repeated exposure）
Product：No data
BHT
There were no reports on humans. In a 4-week transdermal administration study to
mice, lung congestion, swelling, necrosis and degeneration of alveolar epithelial cells
were observed at doses within the guidance values of Category 2 (45 mg / kg / day(90-day conversion value)). Acknowledged (SIDS (2002)).
In addition, in the reproductive test in which rats were fed by diet (administration
period: 5 weeks before mating and mating period for males, and until weaning of F1
infants for females), the dose (100 mg / kg / day) within the guidance value of theclassification was used. There is a description that liver tissue changes (lobular central
hepatocyte hypertrophy, acidophilicity, bile duct hyperplasia) and thyroid hyperfunction
were observed (SIDS (2002), Ministry of the Environment Risk Assessment Volume 6(2008)).
Of these findings, hyperthyroidism was not clear in detail and extent ofhistopathological features, and it was judged that there was insufficient evidence totarget the thyroid gland. As a result, category 2 (lung, liver) was defined.
