Alternative Plasticisers to Phthalates
There should be only two reasons for substitution:
1) on grounds of performance or
2) for health and/or environmental reasons.
In the case of performance there are a number of different plasticisers available but they are generally used because specific properties are required. These include adipates (low temperature flexibility, low viscosity); polyesters (low migration into oil, solvents, adhesives); trimellitates (high temperature cable sheathing); citrates (PVdC film); benzoates (easy processing like BBP); phosphates (fire resistance); and alkyl sulphonates (easy processing and weather resistance). However, phthalates remain the most popular choice because they usually provide the best all-round performance. For further information please refer to the Plasticisers Information Centre
In the case of health and the environmental safety of phthalates, the EU risk assessments show little evidence to suggest that large-scale substitution will be necessary. Indeed, in the case of two of the most widely used phthalates, DINP and DIDP, it has already been clearly stated that no substitution will be necessary as neither phthalate poses a risk to human health or to the environment.
Any recommendation to replace phthalates with less well-studied materials is irresponsible.
