Cyclosia was introduced in 1908.
A smooth and flowery muguet note, very diffusive
A Very pure version of hydroxycitronellal as made by Firmenich who discovered the chemical way back when they were Chuit & Naef
If you want a more diffusive and beautiful hydroxycitronellal use Cyclosia base by Firmenich
it is the original hydroxycitronellal and has diffusion and elegance missing from the regular material. Note that it is not actually a base - but one one chemical
a superior material to hydroxycitronellal which is used instead as its cheaper .
