SECTION 12: Ecological information

12.1Toxicity

• Toxicity to fish: no data available
• Toxicity to daphnia and other aquatic invertebrates: no data available
• Toxicity to algae: no data available
• Toxicity to microorganisms: no data available

12.2Persistence and degradability

Biodegradation data for 1,2-propylene glycol diacetate are not available(SRC). However, ethylene glycol diacetate has been determined to biodegrade readily as measured in the Hach respirometric and OECD screening (die-away) tests using sewage inocula(1). Because 1,2-propylene glycol diacetate is similar in structure to ethylene glycol diacetate, it has the potential to biodegrade readily(SRC).

12.3Bioaccumulative potential

An estimated BCF of 3.2 was calculated for 1,2-propylene glycol diacetate(SRC), using an estimated log Kow of 0.82(1,SRC) 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).

12.4Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1,2-propylene glycol diacetate can be estimated to be about 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1,2-propylene glycol diacetate is expected to have very high mobility in soil(SRC).

12.5Other adverse effects

no data available

SECTION 13: Disposal considerations

13.1Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
