Analysis for nitrosamines and nitrosatable substances Balloon nos.
It can be seen that dibutylamine is stillpresent in the chromatogram, although it is nitrosatable.
Table 7.4 Migration of selected nitrosatable compounds- balloon no.
Has laid down a maximum liberation of nitrosamines from balloons of 0.2 mg/kg and 2 mg/kg for nitrosatable substances.
In the presence of nitrosatable substances(NOX) all five secondary amines can form nitrosamines.
Germany has laid down limit values for release of nitrosamines and nitrosatable substances from balloons.
Nitrosamines and nitrosatable substances are chemicals that are found in such things as fried bacon, smoked meat and rubber products- like latex nipples.
Germany has laid down limit values for release of nitrosamines and nitrosatable substances from balloons.
Analysis for nitrosamines and nitrosatable substances- Survey of Chemical Substances in Consumer Products, No. 89 2007- Analysis of chemical substances in balloons.
The selection is the same as for the analysis for nitrosamines and nitrosatable substances, i.e. balloons nos.
And 20 were selected for analysis for nitrosamines and nitrosatable substances according to DS/ EN 12 868, which as previously mentioned is used by analysis of soothers and bottle teats.
This is why all our raw materials are strictly controlled to ensure they have the lowest possible nitrosamines and nitrosatable substances value.
Table 7.9 Survey of total migration of nitrosamines and nitrosatable compounds in the selected balloons Chemical class.
The analysed balloons all complied with the limit value of 0.2 mg/kg for migration of nitrosamines according to DS/EN 12868, butonly one of the four analysed balloons complied with the requirement to nitrosatable substances of 2 mg/kg.
Conversion of the total migration of nitrosamines and nitrosatable substances to Âμg/kg gives the grand totals stated in the table.
As there was no unambiguous verification of accelerators by the thin layer chromatography,a headspace analysis at GC/MS at 150 °C was carried out on the balloons selected for analysis for nitrosamines and nitrosatable substances.
It is therefore assessed that this method provides too low results for nitrosatable substances at high amine concentrations.
Analyses for content of nitrosamines and nitrosatable chemical substances according to EN 12868 showed that none of the balloon samples were complying with the requirement to limit values for soothers and bottle teats.
Based on results from the TLC-screenings 4 different balloons were selected for analysis for nitrosamines and nitrosatable substances according to analysis method DS/EN 12868"Children Care Articles.
Holland has limits for the content of nitrosamines andnitrosatables and Germany has migration limits for nitrosamines and nitrosatable substances from balloons.
By vulcanisation carbon disulfide will be formed during the release of the secondary amines, which are part of the chemical building blocks for the accelerators:Dimethylamine Diethylamine Di-n-butylamine Diethylphenylamine Dibenzylamine In the presence of nitrosatable substances(NOX) all five secondary amines can form nitrosamines.
The four tested balloons migrated nitrosamines in concentrationsbelow the German limit, but the release of nitrosatable substances was generally in very high concentrations and in three of the four balloons, the migration was higher than the German limit.
The priority criteria were: The balloons must be made of or presumedly made of natural rubber latex The selected balloons must represent manufacturers from Denmark and abroad Both discount andluxury balloons should be tested Balloons with special appeal to children under 8 years Based on results from the TLC-screenings 4 different balloons were selected for analysis for nitrosamines and nitrosatable substances according to analysis method DS/EN 12868"Children Care Articles.
EU directive 93/11/EEC stipulates that rubber teats and soothers may not release nitrosamines and nitrosatable substances in amounts larger than 10 μg per kg rubber for nitrosamines and 100 μg per kg rubber for nitrosatable substances for artificial saliva DS/EN 12868.
A German investigation has shown that for approx.81%of the investigated balloons in 2001, the release of nitrosamines and nitrosatable substances(nitrosamine precursors) for artificial saliva according to EN 12 868(1 hour at 40 °C) was higher than the limit values applying for soothers and rubber teats.
