boiled linseed oil
Our OLI-NATURA boiled linseed oil is, for many, the most authentic and beautiful way to protect wood naturally indoors and outdoors. It is completely biological, vegan, non-toxic, and certified as food-safe. It is produced in a gentle boiling process exclusively from cold-pressed linseed oil with a minimal drying additive. Once cured, it forms a clear, water-repellent protective layer made of linoxin. Boiled linseed oil enhances the grain and the wood's natural color. Particularly light-colored woods take on a pleasant honey tone.
When applied undiluted and several times, it provides effective protection against severe environmental influences. However, several coats require some time and patience. The necessary drying time for the applied coat takes several hours with boiled linseed oil. Only afterward is it possible to proceed with the next steps.
Biological & Ecological
Linseed oil is obtained by cold-pressing the seeds of the flax plant (also called linen). In the case of flax, this is highly efficient because flaxseed consists of around 90% linseed oil. To prevent the oil from becoming rancid in the wood, it is cleaned, degummed, and finely filtered. To accelerate the curing process, the cold-pressed linseed oil is boiled and mixed with a siccative. This turns the linseed oil into boiled linseed oil. The siccative is a manganese drying agent of the latest generation, naturally free of lead salts and cobalt.
Food-Safe
To guarantee its safety, our OLI-NATURA boiled linseed oil was tested and certified by an independent testing laboratory for food safety in accordance with Regulation (EC) No.: 1935/2004. Authenticity and migration tests were also included in the testing: Our OLI-NATURA boiled linseed oil was well below the permitted limit of 0.6 manganese mg/kg, at
< 0.01 manganese mg/kg . This means our OLI-NATURA boiled linseed oil can be safely applied to wooden surfaces that come into contact with food: dining tables, countertops, cheese boards, bread boards, or knife blocks.
Generally speaking
The absorbency of the wood depends on the type and condition of the wood, the user's working method, and the sanding of the wood. Generally speaking:
- Whatever the wood absorbs must be supplied to it.
- Whatever the wood does not absorb must be removed while still wet.
At the same time, the protective effect must be refreshed regularly through occasional re-oiling. Superficial scratches or damage on an oiled wooden surface do not expose unprotected wood, as the oil protects the wood from within. Fine nicks or scratches can therefore also be repaired easily: simply sand the affected areas and re-oil them. Any difference in color will even out over time.
WARNING OF THE RISK OF SPONTANEOUS COMBUSTION!
Particular attention must be paid to oil-soaked rags and cloths, which can spontaneously ignite due to heat buildup. Naturally drying oils cure by absorbing oxygen from the air. This generates heat, which is normally released into the surroundings and is completely harmless. However, in oil-soaked and crumpled rags, cloths, pads, or sponges, the heat cannot escape, meaning that under unfavorable conditions they can spontaneously ignite. Oily cloths or rags should therefore never be left unattended; instead, soak them thoroughly with water, hang them outdoors, and allow them to dry. Treated this way, they can be disposed of safely once dry. Alternatively, oil-soaked rags and sponges can be stored under water or temporarily kept in an airtight, sealable container.
