Creating a Water-Free Serum to Avoid Preservatives
คำถาม
Is it possible to create a water-free serum formulation to avoid using preservatives?
What are the limitations or considerations, especially regarding ingredient solubility?
What types of alternative bases and ingredients, such as Oil or Green Tea Oil, can be used in such formulations?

Hello,
I understand you're looking to create a water-free serum to avoid using preservatives.
It is possible to mix ingredients without using water, but there are significant limitations:
- Solubility Constraint: Most commonly used beneficial skin care ingredients are highly water-soluble. When you don't have water as a solvent in the formula, the ingredients you choose must be soluble in other solvents, such as oil.
- Alternative Base: If you primarily use oil-soluble ingredients, the resulting formula will resemble a skin oil or facial oil, which differs from typical water-based serums.
- Challenge: Finding effective active ingredients that are readily soluble in oil and provide the desired results can be more challenging than using water-soluble ones.
Some product types on the market are oil-based and water-free, such as the example mentioned by the staff: Unicity Green Tea Oil.
Ingredients that can be considered for water-free formulations include Green Tea Oil, which is a natural extracted oil.
In summary, it is feasible by using oil-soluble ingredients instead of water, but you must carefully select ingredients suitable for the oil base and the desired outcome.
