Polyolefin composition
The invention relates to a polyolefin composition comprising A. at least a homopolymer or copolymer of ethylene or propylene and B. cholestanyl ferulate. The composition can be used in the production of articles such as a pipe, cap and closure, film, food contact packaging, biomedical article, health care article and pharmaceutical article.

2. The composition according to claim 1 characterised in that the homo- or copolymer is
high density polyethylene, multimodal high density polyethylene, low density polyethylene, linear low density polyethylene or polypropylene.
3. The composition according to claim 2 characterised in that the homo- or copolymer is bimodal polyethylene.
4. An article produced with the polyolefin composition according to claim 1 .
5. The article according to claim 4 wherein the article is a pipe, cap and closure, film, food contact packaging, biomedical article, health care article or pharmaceutical article.
6. The article according to claim 5 wherein the article is a pipe and is characterised in that the composition comprises a phenolic compound and organic phosphite and/or phosphonite.
7. The composition according to claim 2 characterised in that the homo- or copolymer is high density polyethylene.
8. The composition according to claim 2 characterised in that the homo- or copolymer is multimodal high density polyethylene.
9. The composition according to claim 2 characterised in that the homo- or copolymer is low density polyethylene.
10. The composition according to claim 2 characterised in that the homo- or copolymer is linear low density polyethylene or polypropylene.
