Preserving my formulation
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
