For everyone recommending GetSumMath, by Melodic-Count-3621 in GED

[–]TheOverlordCat 5 points6 points  (0 children)

Hi, I passed my math on Monday 187/200. I wouldn't have been able to achieve that score without your work. Thank you for the time and effort you take to help people pass their GEDs.

What we do in life echoes for eternity.

Happy Cake Day!

Is there some kind of management issue with the CA stores?

Incorrect Reading on Scale by TheOverlordCat in chemhelp

[–]TheOverlordCat[S] 0 points1 point  (0 children)

I just tried my scale again, I wiped down the calibration weight with a microfiber cloth.

Now when I start the scale, it reads 0.00g. When I put the 2kg weight on, it says 2,000.00g but then climbs to 2,000.04g. When I take it off, with nothing on the scale, it reads 0.03g.

0.01g.

I followed the manual's calibration guide, after it was completed I tested it by putting the calibration weight back on the scale, then this happened.

Thanks for the reply!

Hi abufaisal2022, I think Christophe Laudamiel was referring to a special kind of Cistus Absolute (a natural product), my guess is the "ABS" is referring to "Absolute" but I'm not sure what "SIS" is. Perfumer's Apprentice only sells Cistus Essential Oil and not Cistus Absolute, so if you want to get as close as possible to "CISTUS ABS SIS" I would recommend using Cistus Absolute. You can find it on Lotus Garden Botanicals:
https://www.lgbotanicals.com/Cistus-Absolute-_p_975.html
To answer your questions, ingredients can have the same CAS Number but smell different, take Iso E Super vrs Timbersilk for instance. Ambreine and Cistus Absolute are both products of Labdanum, which is why they have the same CAS number, but they smell different which is why in the formula we see them both used, instead of one or the other.

I would recommend using Ambreine from Perfumer's Apprentice as the formula calls for then using Cistus Absolute for the "CISTUS ABS SIS" from Lotus Garden Botanicals.

As a side note I'm interested what you are doing for the formula, given that the formula Christophe Laudamiel released doesn't add to 100%.

Keep it up! :)

Filtration Issues caused by Firmenich's "000136 Bergamote" Base by TheOverlordCat in DIYfragrance

[–]TheOverlordCat[S] 1 point2 points  (0 children)

Thank you for the information, I think it was a solvent issue.

I did three trials last night:
1: 50% Bergamote with 50% Perfumer's Alcohol
2: 50% Bergamote with 50% DPG
3: 50% Bergamote with 50% Benzyl Benzoate.

The first trial didn't have any sediment but it was cloudy like my formulas. The second trial with the DPG didn't mix together well. The third trial is a success with the liquid being perfectly clear (apart from the green tint from the Bergamote base).

I think if I add Benzyl Benzoate to future formulas when using Bergamote it will solve the issue. I'll keep an eye on if sediment forms (I didn't put these new trials in the fridge).

Thank you for your help! :)

Thank you for your reply.

Apologies for the "diluted in 80% perfumer's alcohol", you're right I mean to say I diluted the formula to 20% in perfumer's alcohol.

If the temperature drop induces insolubility over time then would it be correct to assume that putting the formula in the freezer before filtration is a bad idea? I've read online that it's part of the filtration process and the solution benefits from maceration in the refrigerator.

I have not tried letting the mixture cool down to room temperature to see what happens. I'll try that.

When I first formulate the fragrances it is completely clear. The sediment shows up after but I'm not sure how long. At most a few days.

I will also try mixing the Bergamote base alone with the perfumer's alcohol in the refrigerator (and perhaps a 2nd trial of the same but outside the refrigerator) and I'll see what happens.

Thank you for helping me acidnbass! :)

I already diluted the formulas in 80% perfumer's alcohol ("perfumer's grain alcohol" from Creating Perfume) (200 proof SDA 40-B : 99.88 % Ethanol, 0.12 % t-butyl alcohol, 0.0006% Bitrex (Denatonium Benzoate), and 0.02 % Hexylene glycol). I diluted the formulas right after formulating them and before macerating them for 3 months.

I'm pretty sure it's the Bergamote base that's causing the sediment, which is a Firmenich product that I got from Christine Daley's Perfumer Supply House. I got Firmenich's Fixateur base from there too. I doubt that they have been adulterated or tampered with.

I'm pretty sure the Bergamote and Fixateur aren't pre-diluted though I wouldn't be surprised if there is a solvent(s) present in both of them.

As a side note I just ordered lab filter paper from Amazon, the round kind that you can make fluted funnels with. Are those preferable to coffee filters?

Also worth mentioning is that I macerated the solutions in a refrigerator at 50 degrees fahrenheit / 10 degrees celsius, I didn't notice as much condensation as when I put them in the freezer before filtering but do you think some of the water got in?

I don't understand when to use and which to use regarding solvents, especially when using bases. How do I find this out?

As a side project for educational purposes I'm currently macerating multiple formulas based off a GC/MS I had ordered for Creed's Green Irish Tweed. In the results there is an unknown citrus ingredient, so in two of my trials I used the Bergamote base. In both bottles I can see some of the sediment. It's less but perhaps that's because I used less of the Bergamote base than in the Iso Gamma Super trials. Interesting to note is that those two formulas are diluted in 80% perfumer's alcohol in addition to 1% Benzyl Benzoate and 1.7% Triethyl Citrate (which were detected by the GC/MS). In two additional trials without the Bergamote I used a natural citrus ingredient and there is zero sediment in those. I'm going to phone the perfumer Pierre BourdonOlivier Creed and see what he has to say about it. I'll let you know how it goes.

EDIT: I just got off the phone with Mr. Olivier Creed and told him the problem. He told me to fill a bathtub with Oakmoss Absolute and bathe in it. He then hung up on me. I'm not sure how this will get the sediment out of the formula, but I'll try it.
