Linseed oil, also known as flaxseed oil or flax oil (in its edible form), is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant (Linum usitatissimum).
The oil is obtained by pressing, sometimes followed by solvent extraction.
Owing to its polymer-forming properties, linseed oil is often blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing, as a pigment binder in oil paints, as a plasticizer and hardener in putty, and in the manufacture of linoleum.
Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins—which function similarly but resist yellowing.
Linseed oil is an edible oil in demand as a dietary supplement, as a source of α-Linolenic acid, an omega-3 fatty acid. In parts of Europe, it is traditionally eaten with potatoes and quark.
Linseed oil is regarded as a delicacy due to its hearty taste and ability to improve the bland flavour of quark.
Linseed oil is a triglyceride, like other fats.
Linseed oil is distinctive for its unusually large amount of α-linolenic acid, which has a distinctive reaction with oxygen in air. Specifically, the fatty acids in a typical linseed oil are of the following types:
The triply unsaturated α-linolenic acid (51.9–55.2%),
The saturated acids palmitic acid (about 7%) and stearic acid (3.4–4.6%),
The monounsaturated oleic acid (18.5–22.6%),
The doubly unsaturated linoleic acid (14.2–17%).
Applications
Most applications of linseed oil exploit its drying properties, i.e., the initial material is liquid or at least pliable and the aged material is rigid but not brittle. The water-repelling (hydrophobic) nature of the resulting hydrocarbon-based material is advantageous.
Paint binder
Linseed oil is the carrier used in oil paint.
Linseed oil can also be used as a painting medium, making oil paints more fluid, transparent and glossy.
Linseed oil is available in varieties such as cold-pressed, alkali-refined, sun-bleached, sun-thickened, and polymerised (stand oil). The introduction of linseed oil was a significant advance in the technology of oil painting.
Putty
Traditional glazing putty, consisting of a paste of chalk powder and linseed oil, is a sealant for glass windows that hardens within a few weeks of application and can then be painted over. The durability of putty is owed to the drying properties of linseed oil.
Wood finish
When used as a wood finish, linseed oil dries slowly and shrinks little upon hardening. A linseed oil finish is easily scratched and liquid water penetrates a linseed oil finish in mere minutes, and water vapour bypasses it almost completely. Garden furniture treated with linseed oil may develop mildew. Oiled wood may be yellowish and is likely to darken with age. Even though the oil feels dry to the touch, studies show linseed oil does not fully cure.
Linseed oil is a common finish for wooden items, though very fine finish may require months to obtain. Studies show the fatty-acid structure of linseed oil has problems cross-linking and oxidizing, frequently turning black.
Linseed oil is no longer encouraged to use linseed oil to recondition and regenerate finishes because of the cross-linking oxidization that occurs.
Gilding
Boiled linseed oil is used as sizing in traditional oil gilding to adhere sheets of gold leaf to a substrate (parchment, canvas, Armenian bole, etc.).
Linseed oil has a much longer working time than water-based size and gives a firm smooth surface that is adhesive enough in the first 12–24 hours after application to cause the gold to attach firmly to the intended surface.
Linoleum
Linseed oil is used to bind wood dust, cork particles, and related materials in the manufacture of the floor covering linoleum. After its invention in 1860 by Frederick Walton, linoleum, or 'lino' for short, was a common form of domestic and industrial floor covering from the 1870s until the 1970s when it was largely replaced by PVC ('vinyl') floor coverings. However, since the 1990s, linoleum is returning to favor, being considered more environmentally sound than PVC. Linoleum has given its name to the printmaking technique linocut, in which a relief design is cut into the smooth surface and then inked and used to print an image. The results are similar to those obtained by woodcut printing.
Nutritional supplement and food
Raw cold-pressed linseed oil – commonly known as flax seed oil in nutritional contexts – is easily oxidized, and rapidly becomes rancid, with an unpleasant odour, unless refrigerated.
Linseed oil is not generally recommended for use in cooking. Alpha linolenic acid (ALA) while bound to flaxseed ALA can withstand temperatures up to 175 °C (350 °F) for two hours.
Food-grade flaxseed oil is cold-pressed, obtained without solvent extraction, in the absence of oxygen, and marketed as edible flaxseed oil. Fresh, refrigerated and unprocessed, linseed oil is used as a nutritional supplement and is a traditional European ethnic food, highly regarded for its nutty flavor. Regular flaxseed oil contains between 57% and 71% polyunsaturated fats (alpha-linolenic acid, linoleic acid). Plant breeders have developed flaxseed with both higher ALA (70%) and very low ALA content (< 3%).The USFDA granted generally recognized as safe (GRAS) status for high alpha linolenic flaxseed oil.
Linseed oil is an oil obtained from linseed extract and hence its other name is linseed oil.
Linseed oil, which is one of the top oil types for those who are interested in natural and useful products, is produced in two different ways, so its usage width increases.
Linseed oil is obtained by two different techniques as cold press and heating. In the first method, while linseed oil obtained by heat treatment is included in the content of cosmetic products, it is possible to use linseed oil obtained by cold press method directly orally. The benefits of flax oil are not yet fully discovered by humans. When used as a food supplement, flax oil has an important place in hair care and skincare, as well as its effect on restoring health from within.
Linseed oil produced by the heating technique is used in the content of the product in the fields of dyeing and cosmetics.
Linseed oil, linseed oil is a natural oil that has therapeutic properties for stomach and intestinal problems.
Linseed oil has a great role in strengthening the immune system.
Linseed oil is very suitable for people who have dental diseases such as gingival recession and anxiety problems with its relaxing effect.
Linseed oil has a skin-regenerating effect and a quick healing effect on body wounds. Apart from these, it has great benefits on humans in regulating blood sugar and controlling blood pressure.
Linseed Oil Paint is solvent-free paint made from flax oil and natural pigments that do not retain moisture, which can lead to paint failure and widespread wood rot.
Linseed oil, also known as flaxseed oil, is one of the most popular wood finishes in the world. Like other hand-rubbed oil finishes, linseed oil saturates deep into the wood grain to protect against scratches and changes in humidity.
Linseed oil is easy to care for, eco-friendly, and produces a satin finish that really brings out the color and grain of the wood underneath.
Often replaced by synthetic alkyd resins (lacquer, polyurethane, and varnish) for the past several decades, linseed oil is coming back in force lately, much in thanks to its non-toxicity and its environmentally friendly characteristics. Unlike those synthetic alkyds, oil finishes- including linseed oil- seep into the grain of the wood rather than forming a film on top of it.
Linseed oil is derived from the seeds of the flax plant (Linum usitatissimum). The flax plant has been cultivated commercially for textile, seeds, and oil for over 20,000 years. The plant’s fibers are processed into rope, canvas, paper, and linen, which is often found in bed sheets, table cloths, and clothing. The seeds are used as a nutritional supplement and processed further to produce flax oil (also known as linseed oil).
Common Uses of Linseed Oil
We know linseed oil as a popular wood finish, but it actually has several other applications. Some of the common uses of linseed oil are:
-As a finish to preserve wood products, especially those that come in contact with food (ie. cutting boards, wood bowls, etc)
-As a nutritional supplement with many health benefits
-As an additive in oil paint that enhances color and workability
-As a means to clean paint brushes
-As a polish and anti-rust agent for metals
-As a conditioner and cleaner for leather products
Linseed Oil, also known as flaxseed oil is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant (Linum usitatissimum, Linaceae). The oil is obtained by pressing, sometimes followed by solvent extraction.
Flax-based oils are sought after as food because of their high levels of α-Linolenic acid (a particular form of omega-3 fatty acid), but it is important that only food-grade oil be used for food.
Linseed oil is golden yellow, brown, or amber in colour and has the highest level of ALA of any vegetable oil. Food-grade linseed oil is sometimes taken as a nutritional supplement and can be used in cooking, though it is somewhat unstable and goes rancid quickly. Industrially, it is classified as a drying oil because it thickens and becomes hard on exposure to air.
Linseed Oil is slightly more viscous than most vegetable oils and is used in the production of paints, printing inks, linoleum, varnish, and oilcloth.
Linseed oil was formerly a common vehicle in exterior house paints, but its chief remaining use in this field is in artists’ oil paints, which are made by grinding raw pigment into the oil.
Linseed oil is an oil made from seeds of the flax plant.
Linseed oil is used to make paints and inks, or to rub into wooden surfaces to protect them. A yellowish oil extracted from the seeds of flax and used as a drying oil in paints and varnishes and in linoleum, printing inks, and synthetic resins. the oil from linseed, used in paints, for protecting wood surfaces etc
Linseed oil is a natural triglyceride and a well known drying oil. Drying of the triglyceride mainly leads to the oxidation of the unsaturated fatty acid segments and polymerization. Oxidative degradation studies of linseed oil show hardening and oxidation of alkylic sections followed by partial fragmentation of the triglyceride structure.
Application
Linseed oil filled urea–formaldehyde resin microcapsules may be used to fix cracks in paints/coatings. This linseed oil is processed to create a product that is more suited for many uses (such as paint, to name one), in terms of ″drying time.″
Linseed oil is a multi-talented helper and has a positive effect on health due to its high content of omega-3 fatty acids that provide anti-inflammatory support, reduction of blood lipid levels and blood sugar levels, dilution of the blood, improvement of renal values and high blood pressure, increase in anti-oxidants to protect against free radical damage.
Linseed oil supports brain cells and memory. Since the body doesn’t produce its own omega-3 fatty acids, we generally suffer from a shortage of omega-3 fats, so we recommend indulging yourself daily with fresh-pressed organic linseed oil from the Fandler oil mill.
Linseed Oil is a fantastically versatile product.
Linseed oil has a huge range of applications, from use in DIY, to health food supplementation to playing a role in the making of linoleum flooring.
Linseed oil is made by pressing the dried, ripened seeds of the flax plant (Linum usitatissimum). The seeds can be warm-pressed, which gives a higher yield, or cold-pressed, which results in fewer impurities and is usually a better option.
Linseed oil is classified as a drying oil, due to its high content of di- and tri-unsaturated esters. Because of these properties, linseed oil can also be combined with other oils.
Linseed oil has so many uses it’s available to buy in a variety of different forms, with a variety of different names.
Linseed oil is a rich source of α-Linolenic acid extracted from the dried, ripened seeds of the flax plant Linum usitatissimum. Other fatty acids contained in linseed oil include palmitic acid, stearic acid, oleic acid and linolenic acid.
Linseed oil is particularly susceptible to polymerization reactions upon exposure to oxygen in air due to a high content of di- and triunsaturated esters.
Linseed oil is used in drying processes, and is used in other industrial and commercial applications.
Linseed oil is an indirect additive used in food contact substances.
Linseed oil is extracted from flax seeds. The source of linseed oil and flaxseed oil is the same but the processing of both is different where linseed oil is used for industrial purposes and flaxseed oil is quite fit for human consumption. One of the oldest and commercially important crops grown in the cooler climates is Flax. These seeds make a healthy diet as they are rich in omega 3 fatty acids and in dietary fibre. The linseed oil is extracted from both types of flax seeds and appears yellow in colour.
Properties of Linseed Oil
Some properties of linseed oil which make it suitable for the use of industrial purposes are as follows –
Drying properties – Linseed oil dries uniformly but at a slow rate. Due to this characteristic, it is used as a drying agent in wood finish products, paint formulas, etc.
Imparting glow – Linseed oil gives a glowing effect to woods
Water-resistant properties – Linseed oil keeps a substance safe from water. This helps to prevent metal products from corrosion and protects furniture from water damage.
Binding properties – Linseed oil helps in the binding of ingredients in many products.
Linseed oil creates a rich and smooth emulsion when all the ingredients are mixed together.
