Fragrance Formulation with 8 Hours Fragrance Spray Base

Regarding your question about using 8 Hours Fragrance Spray Base with ethyl alcohol and fragrance oil:

1. Adding Water: It is generally not necessary to add water when using 8 Hours Fragrance Spray Base to make the fragrance last longer. This base is specifically designed to help extend the duration of the scent in alcohol-based sprays without needing additional fixatives like musk.

2. Sticky Lump Issue: The sticky white lump you observed when adding water to the base before the fragrance oil is likely due to the incompatibility of the water with the components in the 8 Hours Fragrance Spray Base. This base contains Ethyl Alcohol, Dipropylene Glycol, and Propylene Glycol. While these are miscible with alcohol and fragrance oils, adding water can disrupt the stability of the mixture, especially if not formulated correctly or if a solubilizer is needed.

3. Staining Clothes: A properly formulated alcohol-based fragrance spray that is clear and stable should not typically stain clothes as the alcohol evaporates cleanly. However, if the mixture is unstable and separates, or if it leaves a residue (like the sticky lump you described), it could potentially cause staining on fabric.

Recommendation: It is best to use the 8 Hours Fragrance Spray Base as intended by mixing it with ethyl alcohol and your fragrance oil at the recommended usage rate (60-90% base). Avoid adding water unless you have a specific formulation that accounts for water compatibility and includes necessary solubilizers to maintain a stable, clear solution. Using the base correctly should help achieve longer-lasting fragrance without the need for additional water and minimize the risk of staining.
