Iris, with new and interesting musks, is the central ingredient of the fragrance, found by the perfumer. The perfumer pointed out Iris as a very demanding ingredient, because iris is hard to source, it is affected easily by climate and soil and the other reason is its very time and labour consuming. But Chanel never made any compromise about the quality of her perfumes. The new No.19 Poudre (2011) has the latest technology advances (musks). Jacques polge is the nose behind this fragrance.
