Class | Small Molecule |

Description | Dibutyl phthalate is found in cloves. DBP was added to the California Proposition 65 (1986) list of suspected teratogens in November 2006. It is a suspected endocrine disruptor. It was used in some nail polishes; all major producers began eliminating this chemical from nail polishes in the Fall of 2006. Dibutyl phthalate (DBP) is a commonly used plasticizer. It is also used as an additive to adhesives or printing inks. It is soluble in various organic solvents, e.g. in alcohol, ether and benzene. DBP is also used as an ectoparasiticide. |

Toxicity Profile |
---|
Route of Exposure | Oral (18) ; inhalation (18) ; dermal (18) |
---|
Mechanism of Toxicity | The most characteristic effect of di-n-butyl phthalate is testicular atrophy. Di-n-butyl phthalate exposure causes both the release of iron from hemoglobin and/or transferrin in the liver and spleen, and the subsequent depletion of iron in the blood and testes. The decreased amount of available iron results in a decrease in succinate dehydrogenase activity in the Sertoli cells. This results in disturbances in the energy transfer system between Sertoli cells and germ cells, which is required for the differentiation of male germ cells and their progression through the seminiferous epithelium and release as mature spermatozoa. Di-n-butyl phthalate may also exhibit weak estrogenic activity. It has been shown to exhibit toxic effects in liver mitochondria by uncoupling energy-linked processes and inhibiting succinate dehydrogenase. (18, 1) |
---|
Metabolism | Di-n-butyl phthalate is absorbed via oral, inhalation, and dermal routes. It is rapidly distributed and cleared from the body. Metabolism of di-n-butyl phthalate proceeds mainly by nonspecific esterases in the gastrointestinal tract, which hydrolyze of one butyl ester bond to yield mono-n-butyl phthalate, the primary toxic metabolite. Mono-n-butyl phthalate is conjugated with glucuronic acid via glucuronosyltransferase and excreted in the urine. (18) |

Toxicity Values | LD50: 3050 mg/kg (Intraperitoneal, Rat) (16)
LD50: 720 mg/kg (Intravenous, Mouse) (16)
LD50: 5289 mg/kg (Oral, Mouse) (16)
LC50: 25 g/m3 over 2 hours (Inhalation, Mouse) (16) |

Carcinogenicity (IARC Classification) | No indication of carcinogenicity to humans (not listed by IARC). |
---|
Uses/Sources | Di-n-butyl phthalate is used to make plastics more flexible and is also in carpet backings, paints, glue, insect repellents, hair spray, nail polish, and rocket fuel. (18) |
---|
Minimum Risk Level | Not Available |
---|
Health Effects | Adverse effects from di-n-butyl phthalate exposure have not yet been reported in humans. However, animals studies have shown that di-n-butyl phthalate can affect reproductive ability by decreasing sperm count and causing birth defects. (18) |
---|
Symptoms | Skin contact with di-n-butyl phthalate may cause mild irritation. (18) |
