In 1950, Viña del Mar (Chile) witnesses the start up of Sintex, a company originally devoted to the manufacturing of sodium formate, acid and chemical auxiliaries used in the textile and tannery industry.

In 1955, it founds along with Farmoquímica del Pacífico its first subsidiary, Oxiquim, which starts operations in the industrial area of El Salto (Viña del Mar) and it is still operative, manufacturing and commercializing acetaldehyde and acetic acid.

During the 60’s, Sintex starts the production of another of its traditional manufactured goods by starting up a Molding Compounds Plant.

The successful development of Sintex during the 60’s, allows founding Oxiquim do Brasil (Sao Paulo) in 1974; this company is oriented to the commercialization of chemical products in that country.

By the end of the 70’s, Sintex transferred all its industrial and commercial activities to Oxiquim, assuming the roll of "holding" or investment group. At the same time, it acquires the shares of Oxiquim from Farmoquímica del Pacífico, gaining full ownership over it.
