Safflower ( Carthamus tinctorius ), inflorescence
Safflower achenes
General chemical structure of fats , such as safflower oil. R 1 , R 2 and R 3 therein are long-chain alkyl radicals (<10%) or alkenyl radicals (> 90%) with a mostly uneven number of carbon atoms. Safflower oil is - like other vegetable oils - a mixture of triesters of glycerine , i.e. a triglyceride .

Safflower oil ( safflower oil , safflower oil ) is a vegetable oil obtained from the achenes (fruit) of safflower is obtained. By cold pressing to obtain an edible oil by hot pressing a technically usable oil, are chemically considered both triglycerides . The crude oil is partly refined due to the scratchy taste . Depending on the average composition of the triglycerides, a distinction is made between two types of oil: one with a higher proportion of esterified oleic acid (also high oleic ) and another in which esterified linoleic acid ( high linoleic ) predominates. There is also SL safflower oil (SL stands for Structured Lipids), the fatty acid composition of which has been changed by chemical or enzymatic esterification of the triglyceride. Despite its high content of linoleic acid residues, safflower oil is very stable. The low proportion of saturated fatty acid residues makes it a nutritionally valuable oil.

Other vegetable oils are also called thistle (seed) oil. B. from nodding thistle ( Carduus nutans ), Ruthenian ball thistle ( Echinops ritro ), Benedictine herb ( Cnicus benedictus ), Mexican prickly poppy ( Argemone mexicana ) and also from donkey thistle ( Onopordum acanthium ).

use

kitchen

Since safflower oil is not heat-resistant, it should not be used for frying. However, it is suitable for brief stewing or cooking and as a salad oil . It is often used for vegetable dishes and only stirred in shortly before serving. It is also used in the manufacture of margarine .

medicine

In patients with hypercholesterolemia , safflower oil can be used as a dietary food in combination with a low-fat diet for the prophylaxis and treatment of arteriosclerosis due to its high content of unsaturated fatty acids . It also inhibits blood clotting enzymes such as thrombin and thus lowers the risk of thrombosis in hypertriglyceridemia . In addition to influencing cardiovascular diseases, safflower oil can also be used topically for rheumatism , paralysis, sprains and contusions .

Cosmetics

Safflower oil is widely used in skin care products . It serves as a refatting agent for bath oils and shower gels. It is used as a care oil in the area around the eyes, for severe seborrhea and acne and for normal skin with a tendency to inflammation. Due to the matting effect, it is also used on combination skin with an oily tendency. A soft soap can be made from the oil .

technology

Safflower oil is a slow setting oil . The final strength is reached after about 4 weeks. After 12 hours of cooking, a gelatinous mass ( Afridi wax ) is created, which is used as a substitute for linseed oil in the manufacture of linoleum .

Safflower oil hardly yellows and is used in the manufacture of lacquer , varnish and oil paint . It is also used in the production of printing inks and alkyd resins . It is also used as a fuel and especially in India as a lubricant for leather and ropes.

The initial hardening can be accelerated by adding siccatives . Wood constituents can delay drying. Use outdoors and on exposed surfaces such as floors is not recommended. When treating wood, the safflower oil should be fully absorbed or wiped off the surface again, otherwise sticky or shiny protrusions may remain. Safflower oil can be added to casein colors to improve workability and adhesion.
