The wellness and sustainability mega-trends will have a decisive influence on the future and, because of this, on the behaviour of consumers. Manufacturers will have to be prepared for the changes that will take place early enough so as not to miss the boat. One of the major goals of sustainability is to maintain an optimal balance between increases in manufacturing output, and a clean and safe environment.Sustainability will be one of the main drivers for innovation in order to allow the technical industries to care for the well-being of consumers in a safe and healthy environment. Thus, one area in which significant efforts and progress have been made is in the development of ''green'' or sustainable chemistry.

Carefully selected fatty acids allow esters to be composed which, additionally, have excellent polymerization stabdity (Table 9). Polymerization and in the final resort, carbonization are undesirable reactions occurring when unsaturated oils are exposed to air and heat. Viscosity increases until finally rubber-like films are built up which tend to stick very tightly to solid surfaces and which cannot be removed by any solvent. Polymerization-stable substances are of outstanding importance in the composition of high-quality release agents and bread cutting oils or emulsions. K u r . o $ r and Dr. WMori& for advice and aid in physico-chemical measurements and Dagmar Gobels, Ulrich Haas and Damian Slaps for technical assistance.Etheralcohols (polyols), which are ofinterest inanumberoffieldsofapplication such as, e. g.,PU foams,PU dispersions and PU casting resins,are readily accessible by the acid-catalyzed conversion ofepoxidized fatty materials with mono-and polyvalent alcohols. By means of epoxidized triglycerides and epoxidized oleyl alcohol it is exemplified how polyols with a wideley variable hydroxyl value can be built up by variation ofthe reaction course or the alcohol component. Two selected fields of application are illustrated in more detail.
