ring always resulted in higher odor thresholds compared to thiols with a mercapto group in the side chains. Although all tertiary thiols always exhibited low odor thresholds, none of the 31 compounds reached the extremely low threshold of 1. Also, none of the synthesized mercapto monoterpenoids showed a similar odor quality resembling grapefruit. Although the saturated and aromatic analogues exhibited
1- p-甲基-Nenthene-8-硫醇(1)几十年前被发现是柚子汁中的主要气味物质,它对水果的整体气味有贡献,在空气中的气味阈值极低,仅为0.000034 ng / L。该值是有史以来针对食品气味剂报告的最低气味阈值之一。为了检查结构1的修饰是否会导致气味阈值和气味质量的变化,使用了34个含巯基的对薄荷烷和1- p合成了薄荷烯衍生物以及几种芳族和开链巯基单萜。文献中首次报道了其中的18种,并提供了它们的气味阈值和气味质量以及分析数据。感官数据与1的感官数据比较表明,双键的氢化导致气味阈值明显增加。此外,与在侧链中具有巯基的硫醇相比,将巯基移入环中总是导致较高的气味阈值。尽管所有叔硫醇始终表现出较低的气味阈值,但31种化合物均未达到极低的阈值1。同样,没有合成的巯基单萜类化合物具有类似于葡萄柚的类似气味质量。尽管饱和和芳香族类似物的香气与1类似,但大多数其他化合物的香气被描述为含硫,橡胶

Fragrance accords are provided herein that can provide a consumer with a perception of hygiene. The fragrance accords can include one or more of a citrus compound, floral compound, herbal/aromatic compound, and sulfur containing compound. The accords are suitable for incorporation into a fragrance composition and/or a consumer product to enhance the perception of hygiene. Methods of stimulating the perception of hygiene with the fragrance accords are also provided.
A pro-fragrance composition includes a cucurbituril in complex with a fragrance molecule and use of the compositions in counteracting malodour. The cucurbituril is present as a mixture, wherein the mixture includes at least two different cucurbiturils selected from CB[5], CB[6], CB[7] and CB[8]. The complexed fragrance molecule is released when the composition is exposed to a stimulus. Also provides methods for the preparation of pro-fragrance complexes of cucurbiturils and fragrance molecules.

A liquid, transparent composition comprising microcapsules with at least one odor modulator compound, the composition also comprising at least one perfume. Even though the composition is in capsules, the transparent liquids can be produced using intense and lasting fragrances in the substrate.
The present invention is for sanitizing compositions for sanitizing surfaces which may contact food. The composition may be provided in liquid form, and may include a quaternary amine, one or more surfactant, a fragrance, and water. At least 90% by weight of the fragrance comprises fragrance components that meet Class I qualifications of the Cramer classification system. All other components of the composition (e.g., the quaternary amine, the surfactants, water, and any optional components) meet the EPA guidelines under CFR 180.940(a). Since the composition only includes components that meet the EPA guidelines under CFR 180.940(a) (reflecting a presumption of low toxicity), and at least 90% of the fragrance itself (e.g., in the case of mixtures of fragrance components) meets the Cramer Class I qualifications, the composition is safe for application to surfaces that come in contact with food, where there is a heightened probability that traces of the composition will be ingested.
本发明用于消毒可能接触食品的表面的消毒组合物。该组合物可以液态形式提供,可包括季胺、一种或多种表面活性剂、香料和水。按重量计,至少 90% 的香料由符合克拉默分类系统 I 级标准的香料成分组成。组合物的所有其他成分(如季胺、表面活性剂、水和任何可选成分)均符合美国联邦法规第 180.940(a)条规定的 EPA 准则。由于该组合物仅包含符合 CFR 180.940(a)规定的 EPA 准则的成分(反映了低毒性的推定),且至少 90% 的香料本身(例如,在香料成分混合物的情况下)符合 Cramer I 级资格要求,因此该组合物可安全用于与食物接触的表面,因为在这种情况下,摄入该组合物的微量可能性会增加。
