I am trying to make my own hand sanitiser since it’s sold out everywhere. The formular I use is 1 part aloe vera gel, 2 parts 100% isopropyl alcohol. The problem is when mixing the 2, the solution always forms a small white spongy sticky substance while the rest stays liquid, not gel like:

I tried 2 brands of aloe vera gel and got the same result:

• Palmer Aloe vera gel: Aloe Vera Gel (Aloe Barbadensis), Polyglycerylmethacrylate, Propylene Glycol, Witch Hazel, Algae Extract (Algae), PPG-2-Isodeceth-12, Carbomer, Tocopheryl Acetate, Triethanolamine, Methyl Gluceth-20, DMDM Hydantoin, Tetrasodium EDTA, Quaternium-15, Fragrance (Parfum), Hexyl Cinnamal, Linalool, Geraniol, Limonene, Yellow 5 (CI 19140), Blue 1 (CI 42090).
• Thursday Plantation Aloe Vera Gel: Aloe Vera inner leaf juice equiv. to fresh 974mg/g, Hydroxybenzoates, Diazolidinylurea, Potassium Sorbate and Sodium Benzoate

I am starting to think I got the wrong type of alcohol but the label clearly says pure 100% isopropyl alcohol.

What am I doing wrong?
