Cold pressed Raw Linseed Oil is obtained by ‘squeezing’ the oil out of the seed, without the use of heat, chemicals or solvents. Cold Pressing Oils mean there is no use of heat and chemicals in the production process. Our established Ashburton plant has been dedicated to producing cold pressed Linseed/Flax Seed Oil since 1987.

Some large scale Linseed Oil producers use solvent extraction or heat extraction, exposing the seed to heat and solvents, which damages the properties of the oil. Some also refine, deodorise and bleach the oil, which produces a colourless, bland and odourless oil. This is typically known as boiled Linseed Oil.
