Alkali Refined Linseed Oil, Shelf Life : 1 Year

Alkali-refined linseed oil is a processed form of linseed oil derived from the seeds of the flax plant (Linum usitatissimum). Through an alkali refining process, impurities such as free fatty acids, pigments, and gums are removed to improve the oil's clarity, stability, and drying properties. This refining method involves treating the raw linseed oil with alkali (such as sodium hydroxide) to neutralize acidic components and precipitate out undesired substances. Alkali-refined linseed oil is primarily used in the manufacturing of paints, varnishes, and coatings where clarity and faster drying times are desirable. It retains the inherent qualities of raw linseed oil, such as its ability to penetrate wood and form a durable, water-resistant finish. Artists also use alkali-refined linseed oil in oil painting as a medium for mixing with pigments to create vibrant and long-lasting artwork.
