Someone can knows in what oil it is possible to dissolve pure androstenone -ol (crystal)? Vegetable oils, almond or jojoba interest. It can be possible at increase a temperature or by means of intermediate solvent which then can be dissolved in oil. On the Internet a lot of information that androstenone -ol is dissolved in alcohol. But how to dissolve it in oil I information could not find ☹ Though production on the basis of oils has enough. What oil is used for it and which a technology of dissolving? 😕 ---

You might research DPG or Di-propyleneglycol (?). I think that is what Raw Power and the experimental IH Extreme were based in. It’s oil like but not a true oil. However I have no idea if the [pheromones](https://pheromonelabs.com/) were dissolved directly in the DPG or if they were dissolved in alcohol and then blended with DPG. ---

DPG is a solvent but I am not sure its what they use to actually dissolve there mones in it. They do use it though in products like raw power and A314 but I don’t want to assume anything. Its takes a lot of precise heating and stirring to dissolve dry mone in DPG > [@](#): > > introduced, as a rule with the addition of further solvents, such as dipropylene glycol (DPG) and diethyl phthalate (DEP) and the like, and the solid components are added gradually with vigorous stirring, the mixture being heated externally or by means of internal heating coils until the solids melt or go into solution. Since the heating surfaces have to be heated to relatively high temperatures in order to achieve sufficient heat transport, a certain amount of damage occurs at these heating surfaces as a result of overheating, particularly in the case of sensitive substances. Moreover, the vigorous mixing results in greater contact with air, so that it is necessary to work under an expensive inert gas atmosphere in order to avoid damage by oxidation. > > After dissolution of the solids, the mixture is cooled. Sensitive, readily volatile or chemically unstable materials are then added with gentle stirring, and stirring is continued until the mixture is homogeneous. This method is considerably time-consuming since a disadvantageous solid/liquid mixing ratio is initially present or a time-consuming heating and cooling process is necessary in between and the use of additional solvents not only incurs costs and unnecessarily increases the processing quantities but also additionally pollutes the environment For crystal mones I dissolve in ethanol, 1ml to 1 mg of mones. It takes a few days to dissolve completely. Then I mix this in DPG and add that to the EO so no separation occurs. I have just skipped the DPG step and mixed right in oil bit it gets cloudy and can seperate. You need a high concentration to do this and be able to see the effects in the mones though. I rarely buy the dry mones so my method may not be the best but it works for me. I will see if I can get the Lovely April Marie down here to help. She is the lab tech. Tisha ---

Renny, Tisha23 thank you for help. You are really right, most probably DPG and jojoba oil have to mix. I haven’t been assured of mixing DPG and ethanol, but if you do it then it will be working 🙂 Tisha, which proportion do you use for mix ethanol and DPG, 1:1? About skipping step with DPG… I tested it and had separating too, oil and ethanol can’t mixed. Although it can depend on specific oil. Will be waiting Lovely April Marie for confirming or disproving of our ideas. ---

> [@](#): > > Tisha, which proportion do you use for mix ethanol and DPG, 1:1? Depends on how much anone you want in your EO. DPG and ethanol mix well and DPG is made to mix with water alcohol or oil so the method works. The tough part is getting the ratio right, Anone is a volatile mone to work with this way and I have only done it with EST.

Naturally, it is sometimes necessary to change the concentrations of my, “base solutions,” so that that final product is of another given concentration. So, herein lies my dilemma: When I am diluting solutions in order to change their concentrations, should I use EtOH, DPG or both? If both, then what kind of ratios?

I am thinking about placing an online order with an ebay seller who sells atomizers that look exactly like the to-go atomizers as well as funnels and graduated pipettes.

Thanks! So, I think it to do for home experiment. Chemical laboratory will not open)) And I have one more question concerning some Androstic’s products, but will be better open new post. Georgy
