牋牋In 1934 Heinz Hansen, in second generation, followed his founding father in the business management. Since 1966 the third generation holds responsibility, and the fourth is already involved in leading the company into the 21st century. Up into the early 60ies the company's activities were mainly centred on the marketing of white oils and vaselines, a range of products for which Hansen & Rosenthal is an internationally renowned specialist and knowledgeable business partner. Apart from other branches, traditional buyers are the pharmaceutical and cosmetics industries, especially of white oils and vaselines, products subject to the highest purity standards. The brandname PIONIER stands for the high quality of the products.
