- Cosmetic Ingredient Review Conclusion: On the basis of the data presented in this report, the CIR Expert Panel concludes that Diisopropylamine is safe as a cosmetic ingredient as presently used. Diisopropylamine should not be used in products containing N-nitrosating agents. Source: Cosmetic Ingredient Review (CIR)

- Environmental Bioconcentration: An estimated BCF of 2 was calculated for diisopropylamine(SRC), using a log Kow of 1.4(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 140(SRC) from a log Kow of 1.4(2) and a regression derived equation(3) indicates that diisopropylamine is expected to have high mobility in soil(SRC). A pKa value of 11.07(4) indicates that the protonated form of diisopropylamine will be the dominant species in moist soil surfaces and cations generally adsorb to organic carbon and clays more strongly than their neutral counterparts(SRC). Volatilization of diisopropylamine from moist soil surfaces is not expected to be an important fate process since the cation will not volatilize. The potential for volatilization of diisopropylamine from dry soil surfaces may exist(SRC) based upon a vapor pressure of 79.4 mm Hg at 25 °C(5). Based on screening tests(6,7), biodegradation may be an important fate process in soil, providing sufficient acclimation has occured. However, high concns of diisopropylamine (> 50 ppm) appear to be toxic to microorganisms and, thus, may reduce biodegradation(6,7). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 140(SRC) from a log Kow of 1.4(2) and a regression derived equation(3) indicates that diisopropylamine is not expected to adsorb to suspended solids and sediment in water(SRC). A pKa value of 11.07(4) indicates that the protonated form of diisopropylamine will be the predominant species in water and cations generally adsorb more strongly than their neutral counterparts. Volatilization from water surfaces is not expected to be important fate process(SRC) since the protonated form is not expected to volatilize at environmental pH. According to a classification scheme(5), an estimated BCF of 2(SRC), from its log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Based on screening tests(7,8), biodegradation may be an important fate process in aquatic systems providing sufficient acclimation has occurred. Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), diisopropylamine, which has a vapor pressure of 79.4 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase diisopropylamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 4 hours(SRC), from its rate constant of 9.7X10-11 cu cm/molecule-sec at 25 °C(3). Diisopropylamine is not expected to directly photolyze due to the lack of absorption in the environmental UV spectrum(SRC). Source: Hazardous Substances Data Bank (HSDB)
