Fragrance Usage and Dosage in Roll-on Deodorants

Yes, Bright Crystal Absolu (Compare To Versace) and similar fragrance oils can be used in cosmetic products that come into direct contact with the skin, including roll-on deodorants.

Usage and Dosage

• Dosage: A dosage of 1% is generally considered a standard upper limit for leave-on products like deodorants. However, because the underarm area can be sensitive, it is often recommended to start at a lower concentration (e.g., 0.2% - 0.5%) and perform a patch test to ensure no irritation occurs.
• Application: These fragrances are oil-soluble. If your roll-on deodorant is water-based, you will need to use a solubilizer (such as PEG-40 Hydrogenated Castor Oil) to ensure the fragrance mixes properly and the final product remains clear and stable.

Safety Considerations

• IFRA Standards: While 1% is a common guideline, the specific safe limit depends on the IFRA (International Fragrance Association) category for deodorants (Category 2).
• Sensitivity: Always conduct a small-scale trial and a patch test, as individual skin sensitivity to fragrance components can vary.

The same principles apply to the other fragrances in this category, such as Blue Jeans (compare to Versace) or Bloom (Compare to Gucci).
