Volatilization
The Henry's Law constant for dodecamethylcyclohexasiloxane is 25.0 atm-cu m/mole(1). This Henry's Law constant indicates that dodecamethylcyclohexasiloxane is expected to volatilize rapidly 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 6.2 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 8.4 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is >1 year if adsorption is considered(3). The Henry's Law constant for dodecamethylcyclohexasiloxane indicates that volatilization from moist soil surfaces is expected(SRC). Dodecamethylcyclohexasiloxane is a volatile methylsiloxane that favors partitioning into the atmosphere(4); therefore, dodecamethylcyclohexasiloxane is expected to volatilize from dry soil surfaces(SRC) even with a vapor pressure of 0.0169 mm Hg(5). Evaporation of dodecamethylcyclohexasiloxane was measured in soil studies and found to occur with rates varying with moisture content, soil type and relative humidity(6). Volatilization from soil may be the major loss process under certain moist conditions(7).
Soil Adsorption
Using a structure estimation method based on molecular connectivity indices(1), the Koc of dodecamethylcyclohexasiloxane can be estimated to be 870,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that dodecamethylcyclohexasiloxane is expected to be immobile in soil.

Volatilization
The Henry's Law constant for decamethylcyclopentasiloxane is 33.0 atm-cu m/mole(1). This Henry's Law constant indicates that decamethylcyclopentasiloxane is expected to volatilize rapidly 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 5.6 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 7.6 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 3.8 years if adsorption is considered(3). Decamethylcyclopentasiloxane's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). However, adsorption to soil is expected to attenuate volatilization(SRC). Decamethylcyclopentasiloxane is a volatile methylsiloxane that favors partitioning into the atmosphere(4); therefore, decamethylcyclopentasiloxane is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.3 mm Hg(5). Evaporation of decamethylcyclopentasiloxane was measured in soil studies and found to occur with rates varying with moisture content, soil type and relative humidity(6). 14C-labeled decamethylcyclopentasiloxane was removed from municipal waste by both adsorption to sludge and volatilization(7); the majority of the material was removed via volatilization; after 3 days, 40% of the material in the aeration/secondary clarifier was removed by volatilization(7). From its use in cosmetic products, decamethylcyclopentasiloxane is reported to evaporate from skin or hair within 4-12 hours after application(8).
Soil Adsorption
Adsorption studies using three soils from the United Kingdom (silt loam, sandy loam and sandy clay loam) determined decamethylcyclopentasiloxane log Koc values of 4.98-5.29 with an average log Koc of 5.17 (Koc of 1.48X10+5)(1). According to a classification scheme(2), these Koc values suggest that decamethylcyclopentasiloxane is expected to be immobile in soil.

Volatilization
The Henry's Law constant for octamethylcyclotetrasiloxane is 13.4 atm-cu m/mole(1). This Henry's Law constant indicates that octamethylcyclotetrasiloxane is expected to volatilize rapidly 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 5 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 6.8 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 140 days if adsorption is considered(3). Octamethylcyclotetrasiloxane's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Octamethylcyclotetrasiloxane is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.05 mm Hg(4). Evaporation of octamethylcyclotetrasiloxane was measured in soil studies and found to occur with rates varying with moisture content, soil type and relative humidity(5). 14C-Labeled octamethylcyclotetrasiloxane was removed from municipal waste by both adsorption to sludge and volatilization(6); the majority of the material was removed via volatilization(6); after 3 days, 49% of the material in the aeration/secondary clarifier was removed by volatilization while only 10% was removed by adsorption to sludge(6).
Soil Adsorption
Adsorption studies using three soils from the United Kingdom (silt loam, sandy loam and sandy clay loam) determined octamethylcyclotetrasiloxane log Koc values of 4.17-4.27 with an average log Koc of 4.22 (Koc of 16600)(1). According to a classification scheme(2), these Koc values suggest that octamethylcyclotetrasiloxane is expected to be immobile in soil.
