SINCE 1982

The Group Head Office is based in Romans-sur-Isère, in the Drôme, and houses the administration and support functions for the various operational companies in the Group.

The story began in June 1982. CTH Agri is the fruit of the vision of its founder, Jacques Ritton, based on a hygiene product offer intended for farmers.  

The concept, initially active in the Drôme and the Ardèche, essentially for intensive farming, extends geographically at first until it reaches national coverage. At the same time CTH extends its range to water treatment (the most important source of animal nutrition), a field of activity in which CTH will become the leader. 


CTH acquires Chauveau Nutrition based in Cholet (Maine et Loire)
in 2003. An historical company that is known and recognised in animal nutrition. This acquisition enables the Group to offer real complete solutions in terms of animal nutrition for intensive and ruminant farming. 


From 2006 the Group reorganises its industrial policy with the construction of the SOLUTIO factory at Romans-sur-Isère, the extension of which will be achieved in 2011. An industrial policy which is supported by the takeover of OXENA on the outskirts of Valence. It specialises in the manufacture of disinfectant solutions. 


The Group's international ambition is being built with the creation of the subsidiary, CTH Maroc, then CTH Suisse and CTH Ibérica. 


By acquiring the OCEADIS network in 2018 the agri centre yet again strengthens its presence in farming and reaffirms its first place for sales force and direct farm consultancy in France over its three businesses.

Organization CTH Group


CTH Group offers global hygiene expertise in all its forms.  
One branch organised into two units, in accordance with our two target markets: firstly agriculture through CTH AGRI bringing together the CTH and Océadis brands and then the large retailer activity borne by Oxena through CTH DISTRI.

The Group, cradled by a current of constant innovation, quite naturally built the resources to match its ambitions with the construction of the SOLUTIO factory, the Group's real strong arm.
This production site houses our Research & Development teams and our in-house microbiology laboratory where we ensure the development and validation of our own formulas.
