SECTION 10: Stability and reactivity

10.1Reactivity

Attacks some plastics.

10.2Chemical stability

no data available

10.3Possibility of hazardous reactions

COMBUSTIBLE.TRIPROPYLENE GLYCOL is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. May attack some forms of plastics (USCG, 1999).

SECTION 12: Ecological information

12.1Toxicity

• Toxicity to fish: LC50 - Oryzias latipes - > 1 000 mg/L - 96 h.
• Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - > 1 000 mg/L - 24 h.
• Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - > 1 000 mg/L - 72 h.
• Toxicity to microorganisms: EC50 - activated sludge of a predominantly domestic sewage - > 1 000 mg/L - 3 h. Remarks:Respiration rate.

12.2Persistence and degradability

By analogy to dipropylene glycol, a structurally similar compound, tripropylene glycol is expected to be resistant to biodegradation(SRC). Polypropylene glycol-utilizing bacteria were isolated by enrichment culture; one strain from this culture was able to grow using various polypropylene glycols (diol and triol types) as a carbon source(1). Dipropylene glycol in a five day BOD test, reached 0(2)-5%(3) of the theoretical oxygen demand. Over a four week period with dipropylene glycol added at 30 mg/L, only 0-3% by BOD was degraded(4). Biodegradation of dipropylene glycol proceeds through the oxidation of terminal alcohol groups leading to the cleavage of the ether linkage(1).

12.3Bioaccumulative potential

An estimated BCF value of 0 was calculated for tripropylene glycol(SRC), using an estimated log Kow of -0.50(1,SRC) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value indicates that bioconcentration in aquatic organisms will not be an important fate process(SRC).

12.4Mobility in soil

The Koc of tripropylene glycol is estimated as approximately 13(SRC), using an estimated log Kow of -0.50(1,SRC) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that tripropylene glycol has 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.
