Is Distilled Water Necessary for Mixing with Fragrance?

Generally, standard fragrance oils (หัวน้ำหอม) are not mixed directly with water to make perfume. Fragrance oils are oil-soluble, while water is not. They will not mix properly unless a solubilizer is used.

Perfumes are typically created by diluting fragrance oils in a base, most commonly alcohol (like ethanol) or sometimes an oil base.

Distilled water, such as Purified Water, TDS Limit 1PPM), is essential for cosmetic formulations where water is needed and purity is important, but it is not the typical diluent for creating standard alcohol-based or oil-based perfumes from fragrance concentrates.
