in 1927, heinrich freudenthal formed a family-owned company, deutsche pentosin-werke, creating veterinary and medical products. the high reputation of the products rapidly developed, and by 1935, the company was licensing the production of various pentosin products in other countries, including austria, the czech republic, italy and switzerland. the founder also recognised the need to supply the growing automotive markets, and started development of automotive lubricants and hydraulic brake fluids. around this time, freudenthal recognised that car makers initiated specific product approvals, and pentosin progressed their research and development (r&d) in this direction. pentosin were rewarded with approvals to supply the initial "factory fill", and with the resultant approvals, aftermarket sales progressed in a positive manner. from the outset, freudenthal demanded a key objective of quality in all pentosin products, and this stance still remains today.
