Materials which are toxic as stored or which can decompose into toxic components ... should be stored in a cool well ventilated place, out of the direct rays of the sun, away from areas of high fire hazard, and should be periodically inspected. Incompatible materials should be isolated ...

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 80(SRC), determined from a structure estimation method(2), indicates that isodecyl alcohol is expected to have high mobility in soil(SRC). Volatilization of isodecyl alcohol from moist soil surfaces may be an important fate process(SRC) given an estimated Henry's Law constant of 5.5X10-5 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Isodecyl alcohol is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.1X10-2 mm Hg(SRC), determined from a fragment constant method(4). Theoretical BOD values of 14-24% in 5 days(5) indicate that biodegradation may be an important environmental fate process in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 80(SRC), determined from a structure estimation method(2), indicates that isodecyl alcohol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces may be expected(3) based upon an estimated Henry's Law constant of 5.5X10-5 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 24 hours and 11 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 145(SRC), from an estimated log Kow of 3.71(6), and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is high(SRC). Theoretical BOD values of 14-24% in 5 days(8) indicate that biodegradation may be an important environmental fate process in water.

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), isodecyl alcohol, which has an estimated vapor pressure of 2.1X10-2 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase isodecyl alcohol 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 25 hours(SRC), calculated from its rate constant of 1.5X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of isodecyl alcohol can be estimated to be 81(SRC). According to a classification scheme(2), this estimated Koc value suggests that isodecyl alcohol is expected to have high mobility in soil.

/SIGNS AND SYMPTOMS/ The substance irritates the eyes, the skin and the respiratory tract. Exposure could cause central nervous system depression.

/SIGNS AND SYMPTOMS/ Direct contact with skin can produce irritation. ... Vapors are non-irritating to the eyes and throat. Causes smarting of skin and first-degree burns on short exposure; may cause secondary burns on long exposure.

AEROBIC: In sewage, isodecyl alcohol gave a theoretical oxygen demand of 24, 44, 42 and 39 percent in 5, 10, 15 and 20 days, respectively(1). In acclimated sewage isodecyl alcohol gave theoretical oxygen demand of 14, 26, 45 and 32 percent in 5, 10, 15 and 20 days, respectively(1). Isodecyl alcohol gave theoretical oxygen demand of 6, 17, 34 and 40 percent in 5, 10, 15 and 20 days, respectively, in seawater(1). In a manometric study of poorly soluble compounds, isodecyl alcohol degraded 17.4 and 22.4 percent of ultimate BOD/theoretical oxygen demand with 10 minutes of sonification(2).

An estimated BCF of 145 was calculated for isodecyl alcohol(SRC), using an estimated log Kow of 3.71(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC).

The Henry's Law constant for isodecyl alcohol is estimated as 5.5X10-5 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that isodecyl alcohol is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 24 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 11 days(SRC). Isodecyl alcohol's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Isodecyl alcohol is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.07X10-2 mm Hg(SRC), determined from a fragment constant method(3).

This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Isodecyl alcohol is produced, as an intermediate or a final product, by process units covered under this subpart.
