Formulation Modification: Adding Butylene Glycol and Making a Gel

Question

I want to modify a formulation containing Pitera and Repair Activator. Could you advise on the following points?

1. Can I make this formulation into a gel? If so, what ingredients and percentages should I use? (The current formulation uses 85% Pitera).
2. Do I need to add preservatives and Disodium EDTA?
3. Can I add Butylene Glycol, and what is its function in this type of formulation? Are there other recommended humectants like Glycerin or MOIST24?

Based on the discussion: Making it a gel: Yes, you can substitute a portion of the Pitera (85%) with Pro Polymer (1%) and PE-1 Aqua (1%) to create a gel texture. Preservatives and EDTA: Disodium EDTA is recommended. Preservatives are likely not needed because the high concentration of Pitera (85%) already contains preservatives. Adding Butylene Glycol: Yes, Butylene Glycol can be added. It is water-soluble and acts as a humectant for light moisture. Other humectants like Glycerin or MOIST24 could provide stronger moisturizing effects.
