How to Dissolve 12H Fix in Alcohol

Subject: How to Dissolve 12H Fix

Hello,

Thank you for your question regarding dissolving 12H Fix in Ethyl Alcohol. It sounds like you've tried several methods, but it's still not dissolving completely. This can sometimes happen with fragrance fixatives which can be quite viscous or solid.

Here is a detailed method you can try to ensure proper dissolution:

1. Prepare: Use a clean glass container. Measure the required amount of Ethyl Alcohol (DEB 96%).
2. Add 12H Fix: Gradually add the 12H Fix to the alcohol. It's often easier to dissolve a solid/viscous substance by adding it to the liquid solvent.
3. Stir Thoroughly: Stir the mixture well using a glass rod or stirrer. Initial mixing is important to disperse the 12H Fix in the alcohol.
4. Gentle Heating (if needed): If the 12H Fix does not dissolve readily at room temperature, gentle heating can help. The double boiling method you mentioned is suitable. Place the container in a bath of warm water (not boiling). Aim for a temperature of around 40-50°C. Avoid direct heat or excessive heat, as this can cause the alcohol to evaporate or potentially degrade the fixative.
5. Continue Stirring While Heating: Stir the mixture continuously or frequently while it is in the warm water bath. This helps the solvent come into contact with all parts of the 12H Fix and speeds up dissolution.
6. Check for Dissolution: Continue gentle heating and stirring until the 12H Fix appears to be fully dissolved and the liquid is clear. This might take some time depending on the concentration.
7. Cooling and Standing Time: Once dissolved, remove the container from the warm water bath and let it cool down to room temperature. It is highly recommended to let the mixture stand for at least 24 hours. Check it again after this period. Sometimes, full clarity is achieved only after standing time. Stir again before checking.
8. Filtering (if necessary): If after 24 hours there are still visible particles, sediment, or cloudiness that doesn't disappear with stirring, there might be some insoluble material or the concentration of 12H Fix might be too high for complete solubility in alcohol at room temperature. In this case, you might need to filter the mixture.

The clear lumps you observed could be undissolved or partially dissolved 12H Fix. The sediment could be the same material settling down. Ensure you are using the recommended usage rate for 12H Fix, as using too much can make dissolution difficult.

By following these steps, especially allowing sufficient standing time after gentle heating and thorough stirring, you should be able to achieve a clear solution.

We hope this detailed guide helps!
