Alcohols, C11-14-iso, C13-rich has the potential to degrade in the atmosphere from hydroxyl radical attack and photodegradation can be a predominant daylight atmospheric degradation process for this substance (half-life 6.3 hours).

Aliphatic alcohols are resistant to hydrolysis, and will not undergo direct photolysis in water and soil. As such, these fate processes will not contribute to a measurable loss of this substance from the environment.


Alcohols, C11-14-iso, C13-rich, is expected to be readily biodegradable (61% in 28 days) based on aerobic biodegradation studies using standard OECD test guidelines.  Therefore, biotic degradation will significantly contribute to the loss of this substance from the environment.


Experimental data for Alcohols, C11-14-iso, C13-rich suggests that the substance has a very low potential to bioaccumulate with a mean lipid-normalized steady-state BCF of 39 L/kg, and a lipid-corrected dietary BMF value <= 0.016 (growth corrected whole body half life < 0.58 days).

Transport and distribution:

Soil adsorption of Alcohols, C11-14-iso, C13-rich is expected to occur to a moderate degree (log Koc = 3.17).

Henry’s Law constant (6.91 Pa.m3/mole) indicates that volatilization from water is not expected to occur at a rapid rate, but may occur at a significant rate.

Distribution modeling estimates that Alcohols, C11 -14 -iso, C13 -rich will partition largely to the soil compartment (ca. 77%), followed by the water (ca. 21%), and minimally to air (ca. 1.5%), and sediment (0.44%) compartments
