Stearic Acid?

What is Stearic Acid?

Acido estearico

Stearic acid is a saturated fatty acid present in the vast majority of animal and vegetable oils and fats. In addition, it is found accompanied by other saturated fatty acids and other unsaturated fatty acids. C18H36O2 responds to its formula, which corresponds to the saturated carboxylic acid mono-straight chain with 18 carbon atoms. It is marketed by different purities depending on the origin and the process of extraction always accompanied by palmitic acid.

CAS: 67701-03-5
EC number: 266-928-5

Origin and production of stearic acid

Puede proceder de origen vegetal o de origen animal. Dependiendo del uso que queramos darle usaremos uno u otro.

Vegetable oil is obtained mainly from the hydrolysis of palm oil (or its fractions such as stearin or olein), followed by hydrogenation and subsequent distillation.
This acid of animal origin is obtained from the hydrolysis of animal fat (tallow), followed by its hydrogenation and subsequent distillation. Depending on the degree of hydrogenation (Iodine Index) we can obtain different qualities.

Properties of stearic acid

propiedades del ácido esteárico
Stearic acid is a solid acid at room temperature, generally white with a slight yellowish tinge, practically odorless. Its freezing point ranges from 55 – 65ºC depending on its content and its degree of hydrogenation.

The main applications of this acid are uses as lubricants for plastics, auxiliary products in the textile industry, production of soaps for cosmetics or detergents. It is also applied in the production of waxes, esters, metallic salts, hydrophobic coating agents, candles or rubber for tires.
