Toxicity Profile

Route of Exposure

Oral (4) ; inhalation (4) ; dermal (4)

Mechanism of Toxicity

Phthalate esters are endocrine disruptors. They decrease foetal testis testosterone production and reduce the expression of steroidogenic genes by decreasing mRNA expression. Some phthalates have also been shown to reduce the expression of insulin-like peptide 3 (insl3), an important hormone secreted by the Leydig cell necessary for development of the gubernacular ligament. Animal studies have shown that these effects disrupt reproductive development and can cause a number of malformations in affected young. (1)

Metabolism

Phthalate esters are first hydrolyzed to their monoester derivative. Once formed, the monoester derivative can be further hydrolyzed in vivo to phthalic acid or conjugated to glucuronide, both of which can then be excreted. The terminal or next-to-last carbon atom in the monoester can also be oxidized to an alcohol, which can be excreted as is or first oxidized to an aldehyde, ketone, or carboxylic acid. The monoester and oxidative metabolites are excreted in the urine and faeces. (2)

Toxicity Values

LD50: 3160 mg/kg (Intraperitoneal, Mouse) (4) LD50: 2330 mg/kg (Oral, Rat) (4) LD50: 4170 mg/kg (Oral, Mouse) (4)

Lethal Dose

Not Available

Carcinogenicity (IARC Classification)

3, not classifiable as to its carcinogenicity to humans. (3)

Uses/Sources

Benzyl butyl phthalate (BBzP) is mostly used as a plasticizer for PVC. (5)

Minimum Risk Level

Health Effects

Phthalate esters are endocrine disruptors. Animal studies have shown that they disrupt reproductive development and can cause a number of malformations in affected young, such as reduced anogenital distance (AGD), cryptorchidism, hypospadias, and reduced fertility. The combination of effects associated with phthalates is called 'phthalate syndrome’. (1)

Symptoms

Phthalate esters are endocrine disruptors and can cause a number of developmental malformations termed 'phthalate syndrome'. (1)
