    Acid solutions of FOLIC ACID are sensitive to heat, but towards neutrality, stability progressively increases. Solutions are inactivated by ultraviolet light and alkaline solutions are sensitive to oxidation. It is also inactivated by light. This chemical is incompatible with oxidizing agents, reducing agents and heavy metal ions.

    no data available

    Serious eye damage/irritation

    no data available

    Respiratory or skin sensitization

    no data available

    Germ cell mutagenicity

    no data available

    12.Ecological information

    12.1 Toxicity

    • 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

    12.2 Persistence and degradability

    AEROBIC: Using a defined microbial mixture containing Enterobacter, Citrobacter, Pseudomonas, Klebsiella, Yersinia, and Serratia isolated from unsettled sewage from a primary treatment plant and a separate sewage inoculum, folic acid exhibited low biodegradation rates. BOD rates expressed in terms of O2 mg/L were 11.5X10+2 mg/L and 12.2X10+2 mg/L in the microbial mixture and sewage inoculum, respectively(1). This is 20% of the theoretical degradation products that were obtained using a COD of 6.3X10+3 mg/L(1). These studies indicate that folic acid is slow to biodegrade.

    12.3 Bioaccumulative potential

    An estimated BCF of 3.2 was calculated for folic acid(SRC), using a water solubility of 1.6 mg/L(1) 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).

    12.4 Mobility in soil

    The Koc of folic acid is estimated as 3,400(SRC), using a water solubility of 1.6 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that folic acid is expected to have slight mobility in soil. The estimated pKas of the carboxylic acid moieties of folic acid are 3.5 and 4.5(4), indicating that this compound will primarily exist as an anion and generally do not absorb more strongly to organic carbon and clay than their neutral species(5). However, aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(6,7), suggesting that mobility may be much lower in some soils(SRC).

    12.5 Other adverse effects

    no data available

    13.Disposal considerations

    13.1 Disposal 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.
