Hi Guys,

I am starting my own glitter company selling loose glitter aswell as pressed. Based in the UK so cosmetic glitter is actually acceptable to sell under EU regulations.

i have a slight question about the formulation of my ingredients for the pressed glitter.

at this moment In time im using 
- 99.9% Isopopropyl Alcohol at 50% (3 parts)
- Vegetable Glycerin at 33.3% (2 parts)
- Aloe Vera gel at 16.6% (1 part)

im also going to include the following preservative
 PHENOXYETHANOL, CAPRYLYL GLYCOL, POTASSIUM SORBATE, AQUA, HEXYLENE GLYCOL

However shall I use this at 1% against the weight of the ingredients above including the Aloe Vera gel or shall I scrap the aloe Vera altogether.  

I do do no want too much water in my product so want to reduce the risk of growing mould and bacteria.

i was also want to know what the approx shelf life will be if I add the preservative in.

many thanks in advance

    Don't use Aloe at all. Keep as much water as possible out of your product. In fact, I think you should dump the glycerin also, and use an oil instead - you'll have to experiment to find something soluble in Isopropanol.

    Shelf life is something that you will have to determine for yourself, or have a lab determine for you.

  • Hi Bob, 

    thanks for for the reply, 

    I'll get rid of the aloe... Would the preservatives mentioned above preserve the glycerin well?

    That's another thing you'll have to determine for yourself - but I doubt that preservative will be soluble in glycerin, which will be a big problem, unless it is soluble in alcohol instead.

    There is no substitute for a PET test.

  • I've ordered the preservatives and they should be arriving soon.. I'll trial and error to see if preservatives are soluble in alcohol 

    many thanks for your help. Really appreciate it

    I know that there are a bunch of formulas floating around the web using glycerin as a binder for glitter, but I can't think the wear time would be more than an hour or so. If that doesn't bother your customers, fine, but if I were doing this, I'd look closely at silicone technology instead, and give yourself a competitive advantage.

  • Ok...I will most definitely look into this. Most of my money has been invested into larger quantities of the ingredients above. So once I've managed to make money back on this I will hopefully be successful in coming up with a reformulated product
