    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

    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

    Ok, I am sorry to say Bob already told you silicone is what you want. The formula you posted may look great on you tube but 1. One hr you will have fall out. 2. The feel is scratchy and uncomfortable, not enough slip. 3. Glycerin is not stable in your formula and it will mold. ( There has been complaints about this toward a company in India.) I used this Exact formular, for my 7 yr old dance recital, I would Not put my reputation on the line over it.
