Stearin

Stearin - the name comes from stearic acid containing 16 to 18 carbon atoms. The product has a wide range of applications in various industries. Stearin is most often used as an additive in the production of candles - it hardens the wax, has a beneficial effect on the temperature and length of burning. It is used as an additive - it is added to soap, thanks to which the soap has a shine and makes the product hardened. It is used in cosmetics. It is also used as a consistency modifier, emulsifier, antistatic agent and an agent preventing oxidation. Stearin is used to coat metals, e.g. aluminum and iron powder, these raw materials are found in fireworks, and stearin as an additive makes them can be stored longer. The product has a huge range of applications, it is used in the production of rubber mixtures, e.g. tires, seals, conveyor belts, rubber hoses and synthetic rubbers. In the production of rubber it is used as a dispersant, plasticizer - it softens the product which allows for modification of elasticity, hardness, thanks to the addition of stearin, rubber is resistant to stretching. It is also used as an activator in vulcanization. It is used in the production of PVC, i.e. polyvinyl chloride - it is used as a stabilizer. Stearin is used for polishing - it effectively prevents corrosion or oxidation on metal parts, e.g. tools. Stearin is mainly a mixture of saturated fatty acids. It is produced from animal fats, including beef tallow. Beef fat has the most stearic acid. It is also produced from vegetable fats, e.g. palm oil.
