Inquiry about Eye Preserved availability and choosing a preservative for a formula

Question

Based on a previously discussed formula, I have the following questions: Will Eye Preserved be restocked, and if so, when? Regarding the recommended preservative usage percentage, does "50%" refer to 50% of the water phase or 50% of the total formula? If I need to select one from the currently available preservatives and use it at a 50% reduced concentration for my formula, which one would the staff recommend among: Nature Preserve Global Guard Phenoxyethanol Mild Preserved

Regarding "Eye Preserved", I do not have information on when it will be back in stock.

The staff's recommendation to reduce the preservative level by 50% refers to reducing the percentage in the total formula. For your specific formula using Mild Preserve, the staff recommended reducing it from 1% to 0.5%.

Based on the staff's previous advice for your formula, using Mild Preserve at 0.5% is recommended. However, please remember the caution about potential warming sensation and consider patch testing as suggested by the staff. The staff also recommended adding PE-1 Aqua 2% to improve absorption.
