REACH Phthalates Regulations Amended to Apply to All
DIBP has been widely used as a substitute to DBP to negate the existing restrictions under Annex XVII for the manufacture of products such as PVC, rubber, fiberglass and plastic products, especially in Australia, where DIBP is imported predominantly for the production of PVC and rubber.

The technical feasibility of replacing DBP for different applications will then depend on a range of performance criteria, including inter alia material compatibility, temperature performance, volatility, migration and permanence of plasticiser, efficiency, tensile strength, and hardness.

contains a glycine-to-valine substitution at amino acid 280. This mutation is adjacent to that in the previously studied Ad2+NDlts23. Ad2+NDlts23 exhibits a tem- perature-sensitive defect in DNA replication, and its DBP has previously been shown to bind ssDNA with reduced affinity. Ad2tslllA DBP, like Ad2+NDlts23,
Opinion: A return to import substitution won’t deliver rapid
Sri Lanka has imposed increasing levels of controls on imports since March 2025. While this was partly a reaction to a balance of payments crisis, the restrictions are also intended to promote domestic industrialisation. A strategy of import substitution based on setting up domestic trade barriers can lead to a number of pitfalls resulting in

- How can we quantify the bromine substitution during DBP formation?
- Researchers have developed indices to help quantify the bromine substitution during DBP formation. Bromine incorporation factor (BIF) was introduced by Gould et al. (1983) to investigate the bromine substitution degree of THMs.
- What is BSF in DBP?
- The BSF is defined as the ratio of the molar concentration of bromine incorporated into a given class of DBP to the total molar concentration of chlorine and bromine in that class (Equation (2) ). The BSF is the percentage of bromine in the total halogen of each class of DBP and it can vary from 0 to 1.
- How do disinfection conditions affect DBP speciation?
- These disinfection conditions can affect the formation of the DBPs and they may also impact the competition between chlorine and bromine for the reactions with NOM. There is a lack of quantitative information in the literature on the effect of different disinfection conditions on DBP speciation.
