Dec 11 (Reuters) - Shares in Givaudan fell sharply on Thursday after traders cited disappointing comments on sales guidance during an analyst call ahead of next month's full-year results.

One trader said the fragrance maker did not reaffirm its full-year sales growth guidance of 5.5%.

"Givaudan hosted a group Q4 update... Market conditions more challenging versus the 5.5% OSG (Organic Sales Growth) guide provided in August," Jefferies wrote in a note.

Givaudan was not immediately available for comment.
