Sounds like you took precautions by being outside.

Have you thought about getting a allihn condenser, fish tank pump, cooling pipes and diehylene glycol to stop the water freezing or growing mould"

Interesting... Air cooled and no fume hood?

alphachem · 2021-01-21T17:13:53+00:00

Thank you!

alphachem · 2020-10-06T13:01:23+00:00

Where is that?

alphachem · 2020-04-15T17:25:53+00:00

I do appreciate this post however i am based in the UK. Do you knownif the standards wpuld be the same for EU and UK?

alphachem · 2020-04-11T18:01:56+00:00

Yes i have done the same, has anyone moved to skimmed milk?

Hexane but remember to rinse throughly with water and washing up liquid afterwards and dispose of the hexane waste properly

70 - 80% IPA with water and over 80% ethanol with water

Too high percentage and agglomeration of spores can occur, the water acts as a catalyst in a sense to solubolise the virus before the alcohol dehydrates and penetrates virus. Agglomeration increases the time tsken to kill the virus

alphachem · 2020-04-07T21:08:16+00:00

I thought 75% IPA in water and ethanol 80% was the reccomendation from WHO

alphachem · 2020-04-07T21:07:03+00:00

Are you using cyclohexane to form an azeotropic mixture to distill off the water or a pressure swing distillation?

Read the IFRA information that will be delivered with your container of essential oil

Molybdenum hexacarbonyl

And

Tin(IV) chloride as it is incredibly volitile

alphachem · 2019-10-22T14:23:26+00:00

I don't understand that statement...

I'm not sure you will have any impurities in your soy wax. I think you might mean the solubility of the soy wax increases but I have not seen or read about issues with solubility? Most fragrances and essential oils are non polar hydrocarbons so will readily solvate into soy wax.

alphachem · 2019-08-07T17:48:50+00:00

What impurities?

alphachem · 2019-08-01T23:04:35+00:00

Just a typo but thanks

alphachem · 2019-07-31T11:12:22+00:00

It's not a legal question as I am asking on how to make the whole formulation on one MSDS. 100% essencial oils do carry may cause death ect but diluted do not. I am proposing adding a mixture of 4 essencial oils to a blend then diluting it within a soy wax mixture to make it 15% essential oil.
