Every manufacturing step and every quality check is documented in order to secure the production process and product quality of our excipients for our customers in the pharmaceutical industry. A change management process is in place and the access to production and laboratories is restricted only to authorized employees.
Competence in Ethoxylation & Esterification
50 years’ experience in manufacturing Polysorbates, Sorbitan Esters and other non-ionic surfactants allows us to steer this complex molecular diversity consistently.
Polysorbates, that are ethoxylated sorbitan esters, are widely used in the pharmaceutical industry. The sorbitan esters in polysorbates are also made by KLK Kolb, even at the same location. This is a unique aspect contributing to KLK Kolb’s exemplary proficiency in manufacturing polysorbates and sorbitan esters of high quality for decades and ahead of current market standards for excipients.
