据统计，化妆品过敏中少有35％是由香料引起的过敏。针对可能由于使用香料所引发的问题，各主要相关国际机构与组织出台了相应的法规政策以对香料香精市场进行约束。香精香料直接或间接地与“人体健康”相关联，成为各国政府强制管理的对象。欧盟化妆品法规(ecno.1223/2009-eucosmeticsregulation-inforce)根据医院相关过敏数据的统计结果规定：符合“在不可冲洗型化妆品中含量大于等于0.001％；在可冲洗型化妆品中含量大于等于0.01％”条件时，化妆品香料中26种致敏原物质必须在标签上标注(在欧盟发布的化妆品指令2005年修订前规定香料成分免于标签标注，仅以“香料或香精”标出即可)，借此来提示对此类物质过敏人群购买时应谨慎。

新铃兰醛是一种香气不同寻常、价值极高的含氧萜烯类合成香料，它具有持久的铃兰花香香韵和清淡而甜润的兔耳草花香气，并有丰富的余香，香气温和而稳定，其柔和的花香似羟基香茅醛，但强度更大。由于新铃兰醛在香精配方中的作用显著，越来越受到重视，已经在香水香精等各种香精中逐渐取代了传统的铃兰花香型合成香料铃兰醛的位置。

新铃兰醛，英文名称为lyral，为对(间)-(4-羟基-4-甲基戊基)-3-环己烯-1-甲醛同分异构体的混合物，分子式为c12h22o2，分子量为210.32，化学结构式为式(i)和式(ii)，亦可分别称为新铃兰醛i和新铃兰醛ii或者新铃兰醛1和新铃兰醛2。新铃兰醛是一种重要的精细化学品，为无色粘性液体，具有清淡而甜润的兔耳草花香，有较好的铃兰香韵，香气稳定而持久。新铃兰醛在日化香精中应用广泛，可用于配制香水、香皂、洗涤剂、化妆品等日化产品的香精。

According to statistics, at least 35% of cosmetic allergies are caused by fragrance allergies. In response to the problems that may be caused by the use of fragrances, major relevant international institutions and organizations have issued corresponding regulations and policies to restrict the fragrance and essence market. Flavor and fragrance are directly or indirectly related to "human health" and become the object of compulsory management by governments of various countries. The European Union Cosmetics Regulation (ecno.1223/2009-eucosmeticsregulation-inforce) stipulates that according to the statistical results of hospital-related allergy data: it is in line with "the content of non-flushable cosmetics is greater than or equal to 0.001%; the content of flushable cosmetics is greater than or equal to 0.01%" 26 kinds of allergens in cosmetic fragrances must be marked on the label (before the revision of the Cosmetic Directive issued by the European Union in 2005, it was stipulated that fragrance ingredients were exempted from labelling, and only marked as "fragrance or essence"). This suggests that people who are allergic to such substances should be cautious when purchasing.

New lily of the valley aldehyde is a kind of oxygen-containing terpene synthetic fragrance with unusual aroma and high value. It has a long-lasting lily-of-the-valley fragrance and a light and sweet rabbit ear flower fragrance, and has a rich aftertaste, aroma Mild and stable, its soft floral scent is like Hydroxycitronellal, but more intense. Due to the significant role of new lily of the valley aldehyde in flavor formulations, it has been paid more and more attention, and has gradually replaced the traditional lily-of-the-valley flower-flavored synthetic fragrance lily of the valley aldehyde in various flavors such as perfume essence.

New lily of the valley aldehyde, the English name is lyral, is a mixture of p-(m)-(4-hydroxy-4-methylpentyl)-3-cyclohexene-1-carbaldehyde isomers, the molecular formula is c12h22o2, The molecular weight is 210.32, and the chemical structural formulas are formula (i) and formula (ii), which can also be called new lily aldehyde i and new lily aldehyde ii or new lily aldehyde 1 and new lily aldehyde 2, respectively. New lily of the valley aldehyde is an important fine chemical. It is a colorless viscous liquid with a light and sweet fragrance of rabbit's ear grass. New lily of the valley aldehyde is widely used in daily chemical essence, and can be used to formulate the essence of daily chemical products such as high-end perfume, soap, detergent, cosmetics and so on.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed the determination of new lily of the valley aldehyde in cosmetics by gas chromatography-mass spectrometry, HH-17MS capillary column, and quantitative external standard method, and the results were satisfactory.
