    Description

    Glycerol (also called glycerine or glycerin; see spelling differences) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in all lipids known as triglycerides. It is widely used in the food industry as a sweetener and humectant and in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature.

    No hazard (USCG, 1999)

    4.3 Indication of immediate medical attention and special treatment needed, if necessary

    The clinician should attend to the management of dehydration, electrolyte imbalance (hypokalemia and hyponatremia), hyperglycemia, and acidosis or alkalosis. ... /Osmotic diuretics/

    5.Fire-fighting measures

    5.1 Extinguishing media

    Suitable extinguishing media

    Water or foam may cause frothing.

    5.2 Specific hazards arising from the chemical

    This chemical is combustible.

    5.3 Special protective actions for fire-fighters

    Wear self-contained breathing apparatus for firefighting if necessary.

    6.Accidental release measures

    6.1 Personal precautions, protective equipment and emergency procedures

    Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

    6.2 Environmental precautions

    Ventilation. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

    6.3 Methods and materials for containment and cleaning up

    Wear approved respiratory protection, chemically compatible gloves and protective clothing. Wipe up spillage or collect spillage using a high efficiency vacuum cleaner. Avoid breathing vapor. Place spillage in appropriately labelled container for disposal.

    7.Handling and storage

    7.1 Precautions for safe handling

    Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

    7.2 Conditions for safe storage, including any incompatibilities

    Separated from strong oxidants.Glycerol should preferably be stored at 40 - 60°C under nitrogen blanketing. It is not corrosive and presents little risk of ignition because of its high flash point. Highly concentrated glycerol does not corrode steel, but storage tanks of carbon steel must be protected by surface coating to prevent rusting by residual moisture. Glycerol is therefore usually stored in tanks of stainless steel or aluminum.

    8.Exposure controls/personal protection

    8.1 Control parameters

    Occupational Exposure limit values

    NIOSH concluded that the documentation cited by OSHA was inadequate to support the proposed PEL (as an 8 hour TWA) of 10 mg/cu m for glycerine (mist).

    Biological limit values

    no data available

    8.2 Appropriate engineering controls

    Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.

    8.3 Individual protection measures, such as personal protective equipment (PPE)

    Eye/face protection

    Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

    Skin protection

    Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.

    10.Stability and reactivity

    10.1 Reactivity

    no data available

    10.2 Chemical stability

    Mixtures of glycerin with water, ethanol (95%), and propylene glycol are chemically stable. Glycerin may crystallize if stored at low temperatures; the crystals do not melt until warmed to 20°C.

    10.3 Possibility of hazardous reactions

    GLYCERINE is incompatible with strong oxidizers. It is also incompatible with hydrogen peroxide, potassium permanganate, nitric acid + sulfuric acid, perchloric acid + lead oxide, acetic anhydride, aniline + nitrobenzene, Ca(OCl)2, CrO3, F2 + PbO, KMnO4, K2O2, AgClO4 and NaH. A mixture with chlorine explodes if heated to 158-80°C. It reacts with acetic acid, potassium peroxide, sodium peroxide, hydrochloric acid, (HClO4 + PbO) and Na2O2. Contact with potassium chlorate may be explosive. It also reacts with ethylene oxide, perchloric acid, nitric acid + hydrofluoric acid and phosphorus triiodide.

    10.4 Conditions to avoid

    10.6 Hazardous decomposition products

    Pure gycerin is not prone to oxidation by the atmosphere under ordinary conditions, but is decomposes on heating with the evolution of toxic acrolein.

    12.Ecological information

    12.1 Toxicity

    • Toxicity to fish: no data available
    • Toxicity to daphnia and other aquatic invertebrates: LC50; Species: Daphnia magna (Water flea, age < or = 24 hr); Conditions: freshwater, static, 20-22°C; Concentration: >10000 mg/L for 24 hr /formulated product
    • Toxicity to algae: Toxicity threshold (cell multiplication inhibition test) Algae (Microcystis aeruginosa) 2900 mg/l
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    AEROBIC: Glycerin, present at 100 mg/L, reached 63% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). Biodegradation rate constants of 0.258/day and 0.200/day in respirometric test systems employing activated sludge have also been reported, corresponding to 68% and 78% degradation, respectively(2).

    12.3 Bioaccumulative potential

    An estimated BCF of 3 was calculated in fish for glycerin(SRC), using a log Kow of -1.76(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

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

    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.
