I have just had my reply from customer care
Thank you for your recent email.
As a matter of policy Britvic Soft Drinks only uses fully permitted and
approved ingredients in its drinks within the limit specified by UK
regulations.
The use of food additives was endorsed by the Committee on Toxicity, a
department of the Food Standards Agency, in 2001 following a review of
the suitability of food additives for those with food intolerances.
The Foods Standards Agency has dismissed claims, by the Food Commission,
that additives in food and drinks cause hyperactivity. In fact research
initiated by MAFF and inherited by the FSA, which suggested such a link,
has been rejected by a number of peer review journals and has not yet
been published.
In the opinion of the FSA's scientific experts, the findings are based
on subjective parental observation and there is no conclusive evidence
that food additives are a cause of hyperactivity. The FSA suggests that
the results of the research are not clear and the data questionable.
