Rearrangement of oxiranes, on contact with active Al2O3, earlier studied with methyldialkyl-substituted 1,2-epoxides, has now been extended to 1,2-dialkyl epoxides (cyclohexene oxide, cycloheptene oxide) and β-himachalene monoepoxide (tetrasubstituted). Isomerisation of citronellol epoxide has been investigated to detect any participation of the OH function in oxirane opening. To gauge the importance
先前与甲基二烷基取代的1,2-环氧化物研究过的环氧乙烷与活性Al 2 O 3接触后的重排现已扩展至1,2-二烷基环氧化物(环己烯氧化物,环庚烯氧化物)和β-him麻单环氧化物(四取代) )。已经对香茅醇环氧化物的异构化进行了研究,以检测OH官能团在环氧乙烷开口中的任何参与。为了衡量3β,4β-环氧丙烷重排底物拓扑结构的重要性,已将结果与较早使用3α,4α-环氧丙烷进行重排的结果进行了比较。

-fused himachal-4-en-1-ol was isolated from the foliage of the α-longipinene-producing chemotype of Fitzroyacupressoides . It was characterized by 1D and 2D NMR and by partial synthesis. cis -Bulgar-4-en-1-ol is the probable identity of a co-occurring minor component. Identification of (−)- trans -sesquipiperitol and two epimeric trans -muurol-5-en-4-ols from this species is also reported.
A composition including a plurality of particles, wherein the particles include: about 30% to about 95% by weight of a carrier; about 0.1% to about 30% by weight of a perfume; and about 0.00025% to about 30% by weight of a malodor agent; wherein the malodor agent comprises one or more malodor reduction materials having a Blocker Index of less than 3 or a Blocker Index average of 3 to about 0.001; and wherein each of the particles has a mass between about 0.1 mg to about 5 g.

The present invention relates to antiperspirant and deodorant compositions comprising malodor reduction compositions and methods of making and using such antiperspirant and deodorant compositions. Such antiperspirant and deodorant compositions comprising the malodor control technologies disclosed herein provide malodor control without leaving an undesirable scent and when perfume is used to scent such compositions, such scent is not unduely altered by the malodor control technology.
