Di-n-butyl Phthalate (DBP) - Proposition 65 Warnings Website
Di-n-butyl Phthalate (DBP) Why am I being warned about potential exposure to DBP? DBP is on the Proposition 65 list because it can cause birth defects or other reproductive harm. Exposure to DBP during pregnancy may affect development of the child, and may also harm the male and female reproductive systems.

- What is dibutyl phthalate?
- Dibutyl phthalate: Does not have an individual approval but may be used under an appropriate group standard Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems.
- What is dibutyl phthalate (DBP) EC 201-557-4?
- Substance: Dibutyl phthalate (DBP) EC: 201-557-4 Date of inclusion: >28-Oct-2008 Reason for inclusion: Toxic for reproduction (Article 57c); Endocrine disrupting properties (Article 57 (f) - environment); Endocrine disrupting properties (Article 57 (f) - human health)
- Does dibutyl phthalate have low mobility in soil?
- According to a classification scheme (5), these Koc values suggest that dibutyl phthalate is expected to have low mobility in soil (SRC). A mean sediment log Koc value of 3.8 was calculated from the mean dibutyl phthalate concentration in water and suspended particulate matter from Lake Yssel, The Netherlands (6).
- What is dibutyl phthalate vapor pressure?
- The US Congress has permanently banned dibutyl phthalate in any amount greater than 0.1 percentv in children's toys and certain child care articles. If released to air, a vapor pressure of 2.01X10-5 mm Hg at 25 °C indicates dibutyl phthalate will exist in both the vapor and particulate phases in the atmosphere.
- How many lbs of Diisobutyl phthalate are there?
- (1993) 6,662,000 lbs (includes diisobutyl phthalate) United States International Trade Commission. Synthetic Organic Chemicals - United States Production and Sales, 1993. USITC Publication 2810, Nov. 1994. Washington, D.C., p. 3-101 (1977) 7.72X10+9 G (1982) 7.72X10+9 G
- What is the ambient water criterion for dibutyl phthalate?
- For the protection of human health from the toxic properties of dibutyl phthalate ingested through contaminated aquatic organisms alone, the ambient water criterion is determined to be 154 mg/L.
