Aloe Vera Gel Formulation
I want to formulate transparent aloe vera gel with the help of sprayed aloe powder for commercial use with tea tree oil, Rosemary essential oil and vitamin E, what should I use Xanthan gum or corbopol 940 as gelling agent. Also if any one can help me in complete formula, it would be a great help

Sodium hyaluronate

For a clear and commercial-grade aloe vera gel, Carbopol 940 is the better choice as it creates a transparent, smooth, and professional gel. It requires pH adjustment (5.5-6.5) using Triethanolamine (TEA) or Sodium Hydroxide. Xanthan Gum is more natural but results in a slightly cloudy and sticky gel.

The carbomer that gives clearest gel is Polygel HG (3V Sigma USA) and costs MUCH less than Carbopol 940. I would neutralize that with TEA 99% (not 85% as it has DEA) at 1.2:1.0 ratio. Your freeze-dried aloe vera is acidic so you may disperse it with the carbomer. That is the easy part. The more difficult part will be solubilizing all those oils especially the terpenes. Use Polysugamulse D9 (Colonial Chemical) at 5:1 ratio to start and see what happens. If those oils total < 0.50% you may get clarity, but likely not. Finally add preservative and there are many to choose from. Xanthan gum sucks at making gels and sodium hyaluronate doesn’t gel at all. The former is a good emulsion stabilizer, the latter a good skin-care osmotic agent.
