鈴蘭醛又名百合醛,是一種醛類有機化合物,化學式為C14H20O,常用作化妝品或洗衣粉中的香料。
合成
[編輯]BASF公司通過對4-叔丁基甲苯進行雙陽極氧化來生產鈴蘭醛,年產量超過1萬噸。[2]
在實驗室中,它可由2-甲基烯丙醇和4-叔丁基碘苯在碳酸鈉存在下、氯化鈀催化下反應製得。[3]
性質
[編輯]鈴蘭醛以外消旋混合物的形式生成並銷售,但它的不同對映異構體對其氣味的貢獻並不相同。(R)-異構體具有仙客來或鈴蘭的強烈的花香,而(S)-異構體的氣味則比較淡。[4]
它和乙二醇在二氧化矽負載的硫酸氫銨催化下反應,可以得到相應的縮醛。[5]它和三苯基膦、四溴化碳在二氯甲烷中反應,可以得到4-(4,4-二溴-2-甲基-3-丁烯-1-基)叔丁苯。[6]
安全性
[編輯]歐盟消費者安全科學委員會在2019年認定將鈴蘭醛應用於沖洗型和免洗型化妝品中是不安全的。[7]由於鈴蘭醛在動物研究中被發現有生殖毒性,歐盟將其重新劃分為禁用物質,並於2022年3月起禁止其在化妝品中使用。[8]

Scientific Committee on Consumer Safety. OPINION ON the safety of Butylphenyl methylpropional (p-BMHCA) in cosmetic products (PDF). 2019-05-10 [2020-05-28] (英語).
On individual product basis, Butylphenyl methylpropional (p-BMHCA) (CAS 80-54-6) with alpha-tocopherol at 200 ppm, can be considered safe when used as fragrance ingredient in different cosmetic leave-on and rinse-off type products. However, considering the first-tier deterministic aggregate exposure, arising from the use of different product types together, Butylphenyl methylpropional at the proposed concentrations cannot be considered as safe.
