- Stable, but polymerizes gradually upon exposure to air. Combustible. Incompatible with strong oxidizing agents. Reacts violently with chlorine. Material such as rags impregnated with linseed oil may spontaneously combust after a long induction period due to gradual exothermic reaction with oxygen.

LINSEED OIL Usage And Synthesis
Also known as flaxseed oil, linseed oil is golden yellow, amber, or brown drying oil with a peculiar odor and bland taste. Iodine value 177, saponification value 189-195, acid number(max.) 4 (ASTMD 234-48), polymerizes on exposure to air. Soluble in ether, chloroform, carbon disulfide, and turpentine; slightly soluble in alcohol, spontaneous heating. Combustible. Chief constituents are glycerides of linolenic, oleic, linoleic, and saturated fatty acids. The drying property is due to the linoleic and linolenic groups. Derivation is from seeds of the flax plant Linum usitatissimum by expression or solvent extraction. Various refining and bleaching methods are used. The grades of linseed oil are raw; boiled, double-boiled, blown, varnish makers' and refilled. Used in paints, varnishes, oilcloth, putty, printing inks, core oils, linings, and packings, alkyd resins, soap, and pharmaceuticals.
The botanical properties of linseed oil are listed as emollient, antiinflammatory, and healing. Derived from the flax plant seed, the oil is obtained by expression with little or no heat.
An oil extracted from the seeds of flax (linseed). It hardens on exposure to air (it is a drying oil) because it contains LINOLEIC ACID and LINOLENIC ACID, and is used in enamels, paints, putty, and varnishes.
linseed oil: A pale yellow oilpressed from flax seed. It contains amixture of glycerides of fatty acids,including linoleic acid and linolenicacid. It is a drying oil, used in oilpaints, varnishes, linoleum, etc.
Light yellow to dark yellow oily liquid. Insoluble in water and less dense than water. Hence floats on water. Contains principally glycerides of linolenic, linoleic, oleic and palmitic acid.
Air & Water Reactions
Insoluble in water.
LINSEED OIL react with acids to liberate heat. Heat is also generated by interaction with caustic solutions. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Flammable hydrogen is generated by mixing with alkali metals and hydrides. React with oxygen in the air to harden. Can react with air fast enough to cause ignition of near-by combustible material if the heat builds up in an unventilated space (called "spontaneous combustion" in oily rags).
Contact of liquid with eyes causes mild irritation. Prolonged contact with skin can cause dermatitis. Ingestion of large doses (over 1 oz) has laxative effect.
LINSEED OIL is combustible.
