*1: phr = parts per hard resin, meaning parts per weight <strong>of</strong> hard PVC.<br />

*2: A measure for the plasticiser's efficiency in making PVC flexible; the lower the number,<br />

the s<strong>of</strong>ter the PVC <strong>and</strong> the more efficient plasticiser.<br />

*3 Measured performance in another PVC resin (the same for DEHP <strong>and</strong> EHT).<br />

3.3 Alternative plasticisers <strong>and</strong> polymers used in <strong>to</strong>ys <strong>and</strong> childcare<br />

articles<br />

3.3.1 Toys <strong>and</strong> childcare articles on the Danish Market<br />

Data on alternative plasticisers <strong>and</strong> polymers have been obtained by direct<br />

contact <strong>to</strong> Danish manufacturers <strong>and</strong> larger suppliers <strong>of</strong> <strong>to</strong>ys <strong>and</strong> childcare<br />

articles. A list <strong>of</strong> contacted companies can be found in Annex 1. Five out <strong>of</strong><br />

eleven contacted manufacturers/suppliers have responded with information on<br />

alternative plasticisers, whereas four report that they do not have any experience<br />

with PVC, DEHP, DBP, BBP or <strong>alternatives</strong>. All manufacturers have<br />

been asked <strong>to</strong> provide examples <strong>of</strong> own polymer products containing plasticisers<br />

<strong>and</strong> <strong>to</strong> specify the applied polymers <strong>and</strong> plasticisers. Furthermore they<br />

were requested information on the technical <strong>and</strong> economical applicability <strong>of</strong><br />

the alternative plasticisers.<br />

The results are based on statements by three large companies on the Danish<br />

marked for <strong>to</strong>ys <strong>and</strong> childcare articles. Table 3.4 shows the plasticisers used in<br />

PVC products by these three companies.
