Hair Growth Spray Formulation Adjustment

Question

Based on my hair growth spray formula, I have the following questions:

Does Melatonin Forte™ need Polysorbate 20 (Tween 20) to dissolve?
If I remove Polysorbate 20, what will be the effect on the formula?
Are there any suggestions for adjusting the formula, specifically regarding the use of Sea Kelp Extract and Panthenol (Vitamin B5) ExtraLite™?

Answer 1

Regarding your hair growth spray formula:

Melatonin Forte™ is oil-soluble and does not require Polysorbate 20 (Tween 20) to dissolve with water-soluble ingredients.
If you remove Polysorbate 20, the formula might feel heavy on the hair.
It is recommended to consider reducing the concentrations of both Sea Kelp Extract and Panthenol (Vitamin B5) ExtraLite™ by half for a more suitable consistency.
