U.S. chemicals company DuPont extended its $6 billion takeover bid for Denmark's Danisco by four weeks and said shareholders of 6 percent of Danisco's stock had accepted the offer.

The group's estimate for acceptances up to March 29 was far below the 90 percent acceptance level that DuPont has required to carry out the deal and delist Danisco.

The group said it was awaiting regulatory approval for the deal in China and the EU, and its expectation remained unchanged that this would be obtained.

DuPont has already received competition approvals in the United States.

The offer period would run until April 29 instead of April 1, and the result of the offer is expected to be published on May 2, DuPont said in a statement.

The terms and conditions of the offer as set forth in the offer document remained unchanged, DuPont said.
