Effects of Short-Term (Acute) Exposure

No reports of acute inhalation exposure in humans were located. Dibutyl phthalate (DBP) does not readily form vapour and inhalation exposures are unlikely to occur unless DBP is misted or heated. Animal information suggests that exposure to high aerosol concentrations may result in respiratory tract irritation and mild central nervous system (CNS) depression, with symptoms such as headache, nausea, dizziness and vomiting.

Skin Contact:
DPB is not expected to cause skin irritation. Application of 2% or 5% DBP in petrolatum to humans did not produce irritation in 48-hour closed patch tests.(17) Limited animal information also suggests that it is not irritating.
Animal information suggests that DBP can be absorbed through the skin, but toxicity by this route of exposure has not been reported.

Eye Contact:
DBP may cause mild eye irritation. There is one report of eye contact causing severe stinging pain and tearing but no damage.(11) Limited animal information also suggests that DBP is not irritating.

One case report describes a worker who accidentally ingested approximately 10 grams of DBP. A few hours later he experienced central nervous system effects such as dizziness, nausea and vomiting. These symptoms were followed by pain upon exposure to light, tearing, redness and pain in the eyes with minor renal involvement. Complete recovery occurred within 1 week.(3) Some doubt about the legitimacy of this report has been expressed, because the history of ingestion was obtained with difficulty. In addition, the question has been raised whether one could actually drink DBP by mistake without immediate revulsion, because its taste is so strong and bitter.(11) Ingestion is not a typical route of occupational exposure. Animal evidence suggests that DBP is not very toxic by ingestion.

Effects of Long-Term (Chronic) Exposure

NEUROLOGICAL EFFECTS: A health survey of 147 Soviet employees concluded that polyneuritis (e.g., weakness in the extremities) was a predominant adverse effect. Phthalate ester (including DBP) concentrations were reported to range from 1.7 to 66 mg/m3 (as total mixed esters) in the work environment.(18) It is not possible to state with any certainty that DBP caused this effect because of the concurrent exposure to other chemicals. In another study, peripheral polyneuritis was not observed in 150-250 employees exposed to 8-15 mg/m3 DBP (in addition to other phthalate esters).(9)

SKIN SENSITIZATION: Patch tests carried out on 47 workers who had developed skin conditions showed only 1 subject with a reaction to DBP. No reactions were observed in a control group of 40 subjects.(10) A 5% solution of DBP in petrolatum was tested on 53 human subjects with no positive reactions. Some studies have shown that products containing 4.5-9% DBP were found to be non-sensitizing and non-photosensitizing.(17) However, there are a number of case reports of dermal sensitization to DBP which developed following non- occupational exposure to anti-perspirants and nail polish products which contained DBP.(10) No conclusions can be made from these reports due to the concurrent exposure to other ingredients.


There is no human information available. Limited animal information suggests that DBP is not carcinogenic.

The International Agency for Research on Cancer (IARC) has not evaluated the carcinogenicity of this chemical.

The American Conference of Governmental Industrial Hygienists (ACGIH) has not assigned a carcinogenicity designation to this chemical.

The US National Toxicology Program (NTP) has not listed this chemical in its report on carcinogens.

Teratogenicity and Embryotoxicity:
There is no human information available. DBP has produced fetotoxic effects (e.g. decreased body weight and increased liver weights) in rats and mice at doses which were not maternally toxic. One study has also shown fetotoxicity (reduced body weight), embryotoxicity (fetal deaths) and teratogenicity (cleft palate and skeletal malformations) in rats exposed to non-maternally toxic doses.

Reproductive Toxicity:
There is no human information available. There is conclusive evidence that oral exposure to DBP produces harmful effects on male fertility in several animal species, as evidenced by testicular atrophy and infertility. Reduced fertility has also been observed in female rats and mice exposed orally to DBP.

There is no human information available. One study conducted on human cells in vitro and one mammalian cell in vivo study produced negative results, as have most short-term studies. One in vitro mammalian cell studied produced inconclusive results and weakly positive results have been observed in some tests with Salmonella typhimurium, without metabolic activation.

Toxicologically Synergistic Materials:
No reports of toxicological synergism were located.

Potential for Accumulation:
DBP does not accumulate in the body. It is readily absorbed by the inhalation, oral and skin routes in animal studies and distributed throughout the body. DBP is rapidly metabolized to mainly monobutyl phthalate (MBP) (with small amounts of various oxidation products of MBP and phthalic acid), absorbed and excreted predominantly (31% to 44% ) in the urine with less (20% to 22%) in the feces. Most is excreted within 24 hours and virtually all is removed by 48 hours after exposure.(5,23)


This chemical is a reproductive hazard. Take proper precautions to ensure your own safety before attempting rescue (e.g. wear appropriate protective equipment). Remove source of contamination or move victim to fresh air. Obtain medical advice immediately.

Skin Contact:
Avoid direct contact. Wear chemical protective clothing, if necessary. Quickly and gently blot or brush away excess chemical. Wash gently and thoroughly with water and non-abrasive soap for 5 minutes or until the chemical is removed. Obtain medical advice immediately. Completely decontaminate clothing, shoes or leather goods before re-use or discard.

Eye Contact:
Avoid direct contact. Wear chemical protective clothing, if necessary. Quickly and gently blot or brush away excess chemical. Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 5 minutes or until the chemical is removed, while holding the eyelid(s) open. Obtain medical advice immediately.

NEVER give anything by mouth if victim is rapidly losing consciousness, is unconscious or is convulsing. DO NOT INDUCE VOMITING. Have victim drink 240 to 300 mL (8 to 10 oz.) of water to dilute material in stomach. Obtain medical attention immediately.

First Aid Comments:
Provide general supportive measures (comfort, warmth, rest). Consult a doctor and/or the nearest Poison Control Centre for all exposures except minor instances of inhalation or skin contact.
All first aid procedures should be periodically reviewed by a doctor familiar with the material and its conditions of use in the workplace.

Fire Hazard Summary:
This material can burn if strongly heated.

Extinguishing Media:
Water spray, carbon dioxide, dry chemical powder, alcohol foam, polymer foam. Water spray and foam may cause frothing.(29)

Fire Fighting Instructions:
Evacuate area and fight fire from a safe distance or a protected location. Approach fire from upwind to avoid toxic decomposition products.
Water or foam may cause frothing. The frothing may be violent and could endanger personnel close to the fire. However, a water spray or fog that is carefully applied to the surface of the liquid, preferably with a fine spray or fog nozzle, will cause frothing that will blanket and extinguish the fire. Water spray or fog can be used to absorb heat, keep containers cool and protect exposed material. If a leak or spill has not ignited, use water spray to disperse the vapours and protect personnel attempting to stop a leak. Water spray may be used to flush spills away from ignition sources. Solid streams of water may be ineffective and spread material.
Dibutyl phthalate and its decomposition products may be hazardous to health. Do not enter without wearing specialized protective equipment suitable for the situation. Firefighter's normal protective equipment (Bunker Gear) will not provide adequate protection. Chemical resistant clothing (e.g. chemical splash suit) and positive pressure self-contained breathing apparatus (MSHA/NIOSH approved or equivalent) may be necessary.


NFPA - Health: 2 - Intense or continued (but not chronic) exposure could cause temporary incapacitation or possible residual injury.
NFPA - Flammability: 1 - Must be preheated before ignition can occur.

LD50 (oral, mouse): 4840 mg/kg (10, unconfirmed)

Eye Irritation:

Application of undiluted dibutyl phthalate (DBP) did not produce irritation in rabbits.(35) No further details are available.

Skin Irritation:

Application of 0.5 mL DBP to intact and abraded skin for 24 hours resulted in "very slight irritation" in rabbits.(16)

Effects of Short-Term (Acute) Exposure:

Exposure to high aerosol concentrations (up to 250 mg/m3) for 2 hours caused strong upper respiratory tract irritation, laboured breathing, and central nervous system effects (incoordination, unconsciousness and death) in mice.(12) Lethal oral doses (9930 to 37100 mg/kg) have also produced signs of central nervous system depression in rats and mice.(10)

Skin Contact:
There is evidence that DBP is absorbed through the skin.(2,7) However, toxic effects have not been reported.

Mice administered 470 or 5200 mg/kg in the diet for two weeks developed adverse effects on the kidney at 5200 mg/kg. Necrosis and degeneration of the liver were also observed, as well as thickening and proliferation of the intestinal mucosa and atrophy of the spleen.(13,10) A dose-dependent increase in hepatic peroxisome proliferation (indicating liver damage) was observed in rats administered up to 2.5% (approximately 2100 mg/kg/day) DBP in the diet for 21 days.(14,15) Slightly reduced body weight gain, and increased liver and spleen weights were observed in female rats given 1040 or 5200 mg/kg DBP for 3 weeks. Increased kidney weights were also observed at 5200 mg/kg.(10)

Effects of Long-Term (Chronic) Exposure:

Leukocyte levels were depressed in the mid- and high-dose groups in male rats exposed continuously for 93 days to up to 0.98 mg/m3 DBP. No other adverse effects were reported.(19) Mice were exposed to 20-85 mg/m3 DBP for 86 days and 170-420 mg/m3 for an additional 6 days. The main finding was pulmonary edema.(10) Further details for evaluation are not available.

Skin Contact:
Dermal application of up to 4190 mg/kg/day undiluted DBP to male rabbits for 90 days caused slight dermatitis and pronounced irritation to mucous membranes. At the high dose, slight kidney damage was reported.(16) No further details are available.

Rats and mice were exposed to high dietary levels of DBP for thirteen weeks. Significant reductions in body weight were observed in male rats at 1% and female rats at 2% or 4% and in mice at 0.5% or greater. Significant changes in organ weights (liver, kidney, testis) were also observed. Mild anemia was observed in male rats receiving 0.5% or greater. Liver lesions were observed in rats at 1% and above and in male mice at 1% and female mice at 2%.(5)

Skin Sensitization:
Sensitization was not observed in rabbits receiving daily dermal application of DBP for 90 days.(16) Sensitization was reported in 5/6 guinea pigs in a poorly reported study.(10) Insufficient details do not permit evaluation of this study.

DBP was not carcinogenic when administered to rats in the diet at levels of 0.01% or 0.03% (100 or 300 ppm) for 21 months; or when administered in the diet at 0.05% (500 ppm) for 15 months.(6) No further details for evaluation are available.

Teratogenicity, Embryotoxicity and/or Fetotoxicity:
There is evidence of fetotoxicity (decreased body weight, increased liver weights with increased liver enzyme activity) in rats and mice at doses which were not maternally toxic.(26,27,5) Also, one study has shown fetotoxicity (reduced body weight), embryotoxicity (fetal deaths) and teratogenicity (cleft palate and skeletal malformations) in rats exposed to non-maternally toxic doses.(30)

Reproductive Toxicity:
Exposure to oral doses of DBP has conclusively produced adverse effects on male fertility in several species, as evidenced by testicular atrophy and infertility.(20,21,22,5) Reduced fertility has also been observed in female rats and mice exposed orally to DBP.(24,5)

Analyses of peripheral blood samples from mice exposed to up to 2% (20000 ppm) in the diet did not reveal an increased incidence of micronucleated normochromatic erythrocytes.(5)
DBP was not mutagenic in cultured human leukocytes, with or without metabolic activation or in mouse lymphoma cells, without metabolic activation.(5,10,25) Inconclusive results were reported in a test with cultured mammalian cells (Chinese hamster fibroblasts), without metabolic activation.(31) Weakly positive results have been observed in some tests with Salmonella typhimurium, without metabolic activation.(33,34) DBP was not mutagenic in the Ames assay using several strains of Salmonella typhimurium, with or without metabolic activation.(4,5,32,33) Other short-term tests have also been negative.(4)
