EASY MATHS for perfumery predilutions

[@e.rvanrood7373]

As someone who isn't confident in their math skills...I really appreciate this video! Thank you so much!

[@sammacer]

I’m glad it helped 😊

[@markanthony4546]

Thank you so so much for this video Sam. It’s so informative and easy to understand especially for people who aren’t very good at maths like myself.

[@sammacer]

No problem, really glad it helped!

I really wish your app, was for android as well

[@Cato-gs3xy]

Same.. Apple is so prohibitive because you can't even download apple apps on pc or iPhone

[@mstans100]

alcohol density not same water you need to calculate at if you want to dilute for example I want to dilute rose oil to 10% first take bottle capacity like 100ml multiply it with alcohol density 0.8 100*0.8=80 than multiply it with the percentage you want 80*10/100=8g subtract the result 8 from 80 you get 72 8g rose oil and 72 alcohol

[@sammacer]

That is very true! Useful tip for those people trying to exactly fill a bottle in ml instead of g…

[@wib6044]

Oh wow. Interesting!

[@moal5522]

This might be a beginner question, but for example, is 10mg of a material diluted to 10%, the same as 1mg of the same material undiluted at 100%? Or does different dilutions give materials different effects when adding to a blend, even if the quantity is adjusted to match the concentration percentage? Because when replicating formulas, I would sometimes adjust all the material quantities based on 10% dilutions, since I usually have my materials diluted at 10% Thanks in advance!

[@Ed-qn9kz]

Thank u for this as usual! 🙌🏼 I have a “difficult” Q, hope you can answer. If I have 5g of “rose” diluted to 20% and add it to my other ingredients (combined 15g total) to make the “final” perfume (which I regard as EDP containing close to 20% fragrance oil), my 5g of rose dilution at 20% won’t count as 5g compared to the other 15g undiluted ingredients, right? I’m sure this happens even to you maybe, when you mix diluted and undiluted ingredients together in a final product, is there a formula to calculate the total (real) % amount of undiluted ingredient in the final product? Say you have 5g of 20% rose, 3g musk undiluted, 7g basil undiluted and 5g cedar at 10% in a bottle of 100g. I’d say it is a total of 20g of fragrance oil in that bottle but there really isn’t 20g right? Because some ingredients were diluted? I Hope I make sense. Very honest Q. Thank you!

[@sammacer]

Yes there is a formula - just do the sum of the percent of each component multiplied by it’s dilution written as a decimal instead of a percentage :)

[@blizzardgam3s206]

@@sammacer ive been trying to wrap my head around something with dilutions and I think this sums it up but I have more to ask. So you should us dilutions to tell you how something will smell before you have to make it right? for example test strips containing 10% oils being smelt together will tell you more or less how it would smell in a perfume (EDT type at least)? But some materials like benzoin and vanillin we keep diluted because they come in powders and resins. when going to make your final product you use all your ingredients in their neat form correct? if this is the case should I be adding more vanillin and benzoin in a perfume if I use everything else neat. Should I Even be combining everything neat ? if I combine the diluted materials such as vanillin should I count them as 1/10th the amount added to that perfume? should i be making perfume with only diluted material then adding less alcohol at the end? If i have a really strong thick substance like galaxoide, ill want to dilute it. But when i dilute the material for use in perfume making, what do i consider it mathematically. a fraction of what it actually is?

[@JIBFM]

hey, did you ever get an answer to your question? I've been having this same issue. I don't quite understand if dilutions are only meant to figure out how the materials really smell like or if you use them to add them to the final product and if so, does that mean I have to put in less alcohol to the actual final product? It's confusing @@blizzardgam3s206

[@wyomingpark]

That was helpful. Can you do one now for upscaling? So eg. 450 gms of concentrate and make an edp of 15% with alcohol. Math is my absolute downfall.

[@MrWearily]

I have a question about bottle sizes. What is the best way to do this with bottle size in mind? for instance if i want to make my dilution and have it for a 4ml bottle. I ask because depending on the size of the bottle is going to depend how much material you use, because it has to fit in the bottle.

[@delsonabaya1660]

If we pre-dilute the raw materials, when making perfum edp. Per ex. Are we still do the 20% oils and 80% alcohol?

[@loobsy68]

Thank you so much this is an amazing app

[@mattsteed5761]

This is brilliant thank you!

[@everyday_engineering]

Great job bro🎉

[@CDot05]

Trying to get to grips with this as I want to start; I’m guessing you predilute raw materials and still use the dilutions mixed with alcohol (or solvent of your choice) to create a final perfume? So you predilite the raw materials, then dilute them again in the product bottle to create the final product?

[@WhiteDormouseArtisanSoaps]

I feel the same way. If I’m not mistaken, we are mixing twice. Not to get too confused, but if you have 8oz of alcohol you would not calculate essential oil at 10 to 15% ratio because the fragrance would be too weak. We would have to pre-mix approx. 2 full oz. In order to add it to your alcohol. This can be confusing 🫤

[@WhiteDormouseArtisanSoaps]

Hi Sam, thank you so much for the video. Very helpful. I am a soap maker and create all sorts of bath and body. I have one problem. I make cleaning supplies using 3% ratio of EO app. 27 drops per oz. That’s strong enough for a liquid soap to clean with, but when it comes to perfume using alcohol 40-B 10 to 20 percent of your pre-mixed raw materials is great, but what ratio should we start with when pre-mixing? Should I calculate again at 3 to 4% EO or maybe 50 or 60% which would be approx. 80 drops of EO per oz. These are two different things. The 15 to 20% added to alcohol is the raw materials already pre-mixed. I’m confused about ratios of the EO at this point. We are making a room and linen mist. Why have these two percentages caused me such confusion? Am I looking at it wrong? The 3% EO ratio at 27 drops works for 67 oz of liquid soap, so why is pre mixing for perfume so different? I would need to use your calculation’s because the pre-mix for 8oz. Of alcohol is simply not enough. I was hoping I have not lost you on these few questions. Thank you

[@daniellabuda7744]

Thx for this info! Really nice vid.

[@sammacer]

Thanks!

[@Joxa514]

wow thats so simple to use and figure out thanks for sharing that. i've seen some people explain having to take into account the specific gravity of each component which made it seem overly complicated unlike this method. any thoughts on that?

[@sammacer]

Well yes if you’re using ml. But if you weigh in g you can ignore all that

[@Joxa514]

​@@sammacer ok right thats so much simpler and since asking i've learned to do everything in weight not volume :p. looking back at that initial diluting information i came across it really wasnt explained all that well not mentioning that each fragrance oil has its own specific gravity but mentioning specific gravity in regards to IPM and DPG, only explaining that each thing has its own specific gravity 2 lessons later. thanks for clarifying!

Hey Sam, I have recently bought some pink pepper @ 10.00 in organic DPG. Am I right in thinking this is 10% ? Also can I dilute this to 5% in perfumers alcohol or would I need to dilute it in DPG? Thanks

Q: Can I dilute benzyl benzoate according to the same dilution rule or does it have a different rule?

Hi What about diluting an essential oil with 250 relative odor impact to make its impact 100 by using DPG or IPM. How to manage doing that? Thanks in advance.

Glad I could help!

[@petlover345]

Making sure I’ve got this right… So I’ve got 5 grams of a 10% solution of a material. I want to get this dilution to .1% total in a perfume (perfume totaling to 5 grams). So. Would .05 of the 10% solution added to 4.95 grams equal out to .1% total of the material I want diluted?

[@sammacer]

That sounds right to me

[@akhasry9630]

Hi Sam. Basic question, is DPG containing alcohol?

[@sammacer]

Nope

[@rickscars7395]

Thank you Sam. I’ve been trying to figure out the math English lingo vs American English lingo. So…. When you say “not point oo percent” how would you write that down? In the USA it’s simpler we just say “point zero one percent” written .01%. I always wanted to ask that question so here’s the perfect opportunity😊

[@sammacer]

Yep - when I say “point o 1 percent”, I mean .01% I.e. 0.01%. We just sometimes say “O” instead of “zero”

2,5 g Rose -> 10% ??

[@allysonbriner1883]

Thanks for the maths video! Very appreciated for a music major like me :) Normally when I want to make a 10% dilution, I start with, say .46 grams (for my 5ml bottles). However, it's usually impossible to measure out exactly .46 grams. As such, I get as close as possible, then multiple that number by 9 to see how much alcohol to add (e.g. .43*9 = 3.87 grams alcohol). To calculate the alcohol for a 20% dilution, I multiply the raw material by 4. I figured this out through trial and error. Do you know what number to multiply by for a 5% dilution? 15%? etc. Also, since I have an Android, is there a web site that has a dilution calculator like the one in your app?

[@sammacer]

Thank you! So yeah; I don’t know if another calculator online, but you can just type in the calculation in the video into your calculator with your own numbers. And for 5% it should be x19 and for 15% x5.67 😊

how to diluted 1%, 0.1%

[@dhaiwattrivedi8567]

Hi..i have just started making perfumes at my home and i am regularly watching your videos to get knowledge about perfumery. Actually i am facing some difficulties in understanding the pre-dilutions. For example if i am trying to use all the materials in the pre-diluted form and trying to create a formula for the perfume then i am getting a very low concentration of the perfume raw ingredients. Now how can I increase the concentration of the raw ingredients? Because the accords which i have made at the certain dilution cannot be changed. If i will try to increase the concentration of any particular raw ingredient then it's odour strength will also get changed and so is the accord. So how can I work in this kind of situation? Sorry for the long comment..😃

[@sammacer]

Glad you’re making progress! Yep, that’s something I made Formulair to fix. If you watch my 1 hour long Formulair tutorial (especially the second half), you will see how to easily fix this problem 😊

[@Ci-vaninho]

Are you gonna make a video how you can calculate the percentages of raw materials in a trial? Let’s say you have 0,5 grams of 2% jasmin and 0,23 grams of labdanum 20% etc. and how you can calculate the percentage of each in a blend :)

[@sammacer]

That’s simple - all you need to do is take the number of grams, multiply by the percentage, and then finally divide by 100
