Rubinum S.A. is a company dedicated to the manufacturing and selling of Toyocerin^® worldwide since undergoing a change in ownership in March 2008.

Toyocerin^® has its origin in Europe in 1988, where Toyo Jozo Ltd., a Japanese company, started to run a sister company with a minor shareholder Andersen S.A. called Toyo Jozo S.A., established in Rubí, near Barcelona. In 1992 Toyo Jozo S.A. changed its name to Asahi Vet S.A. due to the acquisition of the company by Asahi Kasei Corporation.

In 2005, Andersen S.A. bought all the shares of the company from Asahi Kasei Corporation becoming the owner of the new company called Rubinum S.A.
