Regarding the full ingredient list, could you provide typical usage percentage ranges for the key components and general instructions on how to incorporate them into the formula? 3. Can I use **Polysorbate 20** or **Polysorbate 80** instead of **PEG-40 Hydrogenated Castor Oil** as the primary solubilizer? 4.
