Answer

Troubleshooting Precipitation in Perfume Spray with 12H Fix™

Based on the information about 12H Fix™ (Fragrance Fixative), the precipitation you are experiencing is likely because the 12H Fix™ is not fully dissolving in the alcohol base.

The product description for 12H Fix™ specifies a particular method for use in alcohol-based formulas like perfume sprays. It requires pre-dissolving the 12H Fix™ with a suitable solvent like LipidSoft™ Lite using heat before adding it to the alcohol. Simply heating the final mixture may not be sufficient to achieve full dissolution.

Here is the recommended method for using 12H Fix™ in an alcohol-based perfume spray:

  1. Dissolve 12H Fix™ with LipidSoft™ Lite: Mix the 12H Fix™ with LipidSoft™ Lite. The recommended ratio is at least 2 parts LipidSoft™ Lite for every 1 part of 12H Fix™. For your formula using 5% 12H Fix™, you would need at least 10% LipidSoft™ Lite. Heat this mixture to 60-70°C until the 12H Fix™ is completely dissolved.
  2. Add Fragrance: Once the 12H Fix™ is dissolved in LipidSoft™ Lite, mix in your fragrance oil without using heat.
  3. Combine with Alcohol: Add this dissolved mixture (12H Fix™ + LipidSoft™ Lite + Fragrance) to your 95% Ethyl Alcohol and mix until uniform.

By pre-dissolving the 12H Fix™ in LipidSoft™ Lite, you ensure it is properly solubilized before being introduced to the alcohol, which should prevent precipitation.

You will need to adjust your formula to include LipidSoft™ Lite. For example, if you keep 12H Fix™ at 5% and Fragrance at 23%, and add 10% LipidSoft™ Lite, your formula would look something like this:

  • 12H Fix™: 5%
  • LipidSoft™ Lite: 10%
  • Fragrance: 23%
  • 95% Ethyl Alcohol: 62% (to reach 100%)

Please try this method, ensuring the 12H Fix™ is fully dissolved in the LipidSoft™ Lite with heat before combining with the alcohol.
