    Default Delta Octalactone vs Bicyclononalactone

    I'm doing a little fragrance demo from the scent & chemistry facebook page https://www.facebook.com/ScentChemis...type=3&theater, and the Delta Octalactone provides a creamy-lactonic, fluffy-white aspect to this jasmine accord. I do not have the delta octalactone in my palette, but I do have the Bicyclononalactone which seems to be very similar. If anybody possesses these two ingredients- can you kindly provide your input on the scent description difference if any? Susan at CreatingPerfume.com has kindly honoured my request to order this material so I will be ordering this in the coming weeks as it is very versatile and has tremendous longevity to boot!

    Delta Octalactone - sweet fatty coconut tonka tropical dairy

    Bicyclononalactone - sweet herbal coumarinic tonka woody

    Both have ~400 hr longevity and medium strength. From TGSC....

    I know you do Paul! ha ha, can you tell me in your opinion, do you detect the aspect of coconut in the Bicyclononalactone(whew! that's a mouthful) ? I do myself, but I guess I'll ultimately wait until Susan's order comes through...

    Yes this is exactly why I'm asking feedback, since they're similar I might use the latter as a substitute for now..was thinking of using methyl laitone but that has a "high" odour strength..perhaps should stick to medium odour strength eh.....thanks so much for your insight

    That accord you posted looks nice without either. I have gamma octalactone and bicyclononalactone and if I had to I would put the gamma octalactone instead, but do you have alc c8 or maybe ethyl lactate you could do a trial replace with for now?

    Bicyclononalactone is not a replacement for Delta Octa.

    Look up what Harry said on the Perfumemaking FB group.

    HI Paul, I did refer to Harry's FB feedback, and yes I did think of those including maybe methyl laitone, but will wait for Susan's order at CP, thanks again Paul for your feedback - You're the best!

    I guess that's what I was implying, they are different. I wouldn't say they could be substituted but I haven't done an eval. on both.

    I wouldn't use bicyclononalactone as a substitute for deltaoctalactone. They are rather different and delta is much stronger. I have bicyclo sorted with the vanillin sort of acs and delta is pure lactone.

    thank you kindly for taking the time to share your insight. I am going to wait for susan's order of the delta oct at Creatingperfume.com. yes I should have really thought about it first, it was chosen specifically in the accord for it's "milky" type apsect which the bicyclo is lacking. Whilet he bicyclo may have a small coconut odour to it, it lacks the "milky thickening" type trait. cheers, S

    The main difference between these two is that the bicyclononalactone is a base note and gamma octalactone a heart note. Delta Octalactone is "milkier" and fruitier but both lack the rich milky, buttery aspect imho. Bicyclononalactone is nice oriental if you will, hay, tonka, dry, oriental, sweet, pairs great with ethyl vanillin and coumarin, sandalwoods and amber extreme. Delta octalactone is whiter, peachier, dry coconut mid note, tad creamier, lacks volume. Methyl laitone imho always comes prediluted at 10% so I never experienced its "enormous" strength, not really irreplacable like some may think. To me it smells like cold milk or coconut milk out of the fridge with a hint of fruit (cold lemons) if that makes any sense:-).
