This is reflected more particularly in the flower industry, where the cost of collecting the blossoms delivered to the factories has gone up year after year, so much so that most flowers with the possible exception of Mimosa, have reached a cost price which has compelled the perfumer to either reduce his purchases of absolutes and concretes, or alternatively to substitute them from a cheaper source, or even to discontinue their use. This development raises an important and almost insoluble problem for the perfumer, who is faced with the necessity of trying to keep unchanged the bouquet of his fragrances, and moreover, to ensure no loss of strength and diffusiveness. Of course, this problem applies more especially to the adjustment of formulae for established perfumes, because in every new creation the present high cost of raw materials receives imperative con- sideration before the formula is approved. | | 出版日期 | Book 1993Latest edition | | 關(guān)鍵詞 | classification; cosmetics; fixation; production; chemistry | | 版次 | 9 | | doi | https://doi.org/10.1007/978-94-011-1484-4 | | isbn_softcover | 978-94-010-4651-0 | | isbn_ebook | 978-94-011-1484-4 | | copyright | Chapman & Hall 1993 |
