hi, stallion! let me make one remark to your primer on mesuring: when counting drops you MUST dilute your materials beforehand, also assuming that you will use liquids as well as solid, cristaline, etc. materials! preferably at a 10% strength, otherwise you could never repeat your experiments precisely! this dillution should then be made by weighting the fragrance material as well as your dilluent.
Feel free to give me your comments on the layout. 8)
Coconut oil will not mix with ethanol. The usual concentration of a fragrance for personal use is between 15.0% to 20.0%.First post so please forgive me if I'm not posting in the right spot. :0)
Quetsion: I'm trying to create a 100% organic spray perfume. Can I mix organic fractionated coconut oil and organic 80 proof vodka as carriers? I was hoping this would dilute the oil enough to make the perfume sprayable without clogging, and also prolong shelf life. If this sounds right, what ratio of essential oils, fractionated coconut, and organic vodka should I use, and will mixing fractionated coconut and vodka actually prolong shelf life? Thanks so much for any help!!! :0)
I am curious if anyone knows how to create the scent of human sweat? I have heard that cumin resembles body sweat and skin.
Perhaps it's a mixture of leathery scents? There's something else there. Maybe it's is, gasp, garlic?
if anyone has any notes on adding a human edge to parfum I would love to hear them!!!
Are there anybody else heard that cumin resembles body sweat?It's an important knowledge for me.But it need to be confirmated.I wonder really, is it smell such as or nearly body sweat?Please explain if you are sure.
The smell of sweat depends on so many things; your sex, your diet, your state of health, the freshness (or otherwise) of the sweat, and a few others things. Cumin has been described as smelling "sweaty". It is easy to find out; go to your supermarket and find where they keep their herbs and spices. See what you think. To get a more unpleasant sweaty feet type smell, try a touch of iso Valeric Acid.
[For that 100 ml 25% concentrated perfume spray, do I have to mix
1) 25 ml oil in 100 ml solvent
2) 25 ml oil in 75 ml solvent?
I’m just adding here something that seems to come up quite often when people are trying to work out how to read a formula, work out how to do dilutions, blending or similar things. I’ve linked to a some relevant parts of my blog but the following basic concepts are fairly essential if you are going to get anywhere:
A perfume formula is normally expressed independently of any unit of measurement so that it can be made in any amounts that may be required, it is however almost always based on weight rather than volume, so grams, ounces, Kg, pounds or tonnes . . . as long as you keep the same proportions, it will be the same perfume.
The convention is that formulas add up to 1000 - there is no need for them to do so - it’s just a convention. However it does help when it comes to adding small amounts of high impact materials if you can conveniently express 0.1% of the concentrate as 1. If you need to add just a trace of a very high impact material, such as civet, then you can use a 10% dilution in the formula and easily get to 0.01%, or a 1% dilution and get to 0.001% and so on, without making it difficult to specify large amounts of low impact materials, such as Hedione, where you might want 30% of your formula - so you would express that as 300.
It helps to understand the concepts of ratio, proportions, percentages and, if you want to convert between weight and volume, specific gravity.
If you do everything by weight then specific gravity is only relevant when you need to know what bottle size a given weight will fit in and for that the most important factor is usually the ethanol (specific gravity of 0.8).
If you are working in drops then you need to know what size the drops are and the specific gravity of the liquid you’re dropping in order to know how much you are putting in.
If you are going to sell your perfume you will need to be concerned with the IFRA Standards and other rules. Regulations regarding perfumery are expressed on a weight for weight (w/w) basis.
You may be familiar with seeing the alcohol content specified by volume (v/v or ABV on the label) but that is only relevant for regulation of taxes on ethanol, for everything else, you need to know the weight.
Hope that’s useful.
