Questions about Mild Preserved Eco Solubility and Rose Water in Serum, and Tea Tree Oil Effectiveness in Toner for Acne

Question

Based on the staff's recommendation to change Phenoxyethanol to Mild Preserved Eco 1% in a skin brightening and strengthening serum formulation:

Mild Preserved Eco cannot dissolve in water. Can it still be used in this formulation?
Can plain water be replaced with Rose Water (which already contains preservative) instead of using plain water + preservative? This would also add fragrance.

Also, regarding a toner formulation for acne reduction, the staff mentioned that Tea Tree Oil (Water Soluble) is primarily effective for inflammatory acne. For clogged acne, which is often the root cause, Tea Tree Oil may not be sufficient. Could you elaborate on this?
