Hypotheses - factors promoting and restricting substitution

A set comprising 15 hypotheses was compiled in the course of the project. These hypotheses are presented and explained in the following  

Hypothesis tl) Current ehemieals legislation ereates eompetitive advantages for existing materials , whieh impede innovation 

The cnrrent registration procedure for new substances in Europe (high information reqnirements even for small quantities), together with the absence of binding test reqnirements for existing substances, represents a hindrance for substance innovation in the area of high-volume, established industrial chemicals. 

With regard to the case studies contained in the SubChem project, the effects of the different requirements placed on new substances and existing substances can best be illustrated using the case study of plasticisers for PVC (DINCH as a substitute for DEHP). 

Hypothesis (2) Under current chemicals legislation environment and health-related qnality competition between chemicals is hampered hy a lack of substance information
