Aloe Vera powder can be used in topical products and keeps longer than Aloe Vera gel. For those who are allergic to Vitamin E, the powder does not contain any. However, Aloe Vera gel is preserved with Vitamin E to keep it stable and extend its self life. If you make products for hair & skin, try adding this in place of the gel. 
Risks: Do not apply topical aloe vera to deep cuts or severe burns. People allergic to garlic, onions, and tulips are more likely to be allergic to aloe. High doses of oral aloe are dangerous. Long-term use may increase the risk of colorectal cancer. 
Don’t take oral aloe if you have intestinal problems, heart disease, hemorrhoids, kidney problems, diabetes, or electrolyte imbalances.
Interactions. If you take any drugs regularly, talk to your doctor before you start using aloe supplements. They could interact with medicines and supplements like diabetes drugs, heart drugs, laxatives, steroids, and licorice root.
