Question

I am planning to use Ethyl Alcohol (96%, Perfumer Grade, Low-Odor) for mixing perfume.

  • Does the 96% grade have a truly low odor, similar to Ethyl Alcohol 99.9%?
  • How significant is the difference in performance when mixing perfume between the 96% and 99.9% grades?
  • What is the volume (in Liters) of 1 kilogram of Ethyl Alcohol (96%, Perfumer Grade, Low-Odor)?

Answer

Here is the comparison between Ethyl Alcohol 96% and 99.9%, along with the volume calculation for 1 kg of 96% alcohol.

1. Odor Comparison (96% vs. 99.9%)

Both products are Perfumer Grade and are specifically selected for their low odor, making them suitable for perfume mixing.

  • Ethyl Alcohol 99.9% (ID 706): This is the highest purity grade (200 Proof) and is described as having a very mild smell (low odor). Due to its minimal water content (less than 0.25%), it is the most neutral and least-scented option available.
  • Ethyl Alcohol 96% (ID 35354): This grade is described as having a mild odor and "no foreign smell." While it is excellent for perfume, the 99.9% grade is technically purer and will have a slightly more neutral profile.

Conclusion: Both are excellent low-odor choices, but the 99.9% grade is technically more odorless due to its higher purity.

2. Performance Difference in Perfume Mixing

The main difference when mixing perfume is the water content:

Feature Ethyl Alcohol 99.9% Ethyl Alcohol 96%
Purity 99.9% (Minimal water) 96% (Contains 4% water)
Performance Premium choice, ensures maximum solubility and volatility. Preferred for high-end or complex fragrances where water content must be minimized. Excellent and economical choice. The 4% water content is generally acceptable for most standard perfumes and can sometimes help with the initial "bloom" of the fragrance.
Cost Higher Lower

Conclusion: For most standard perfume formulations, the difference in the final product will be minimal. The 96% grade is a highly economical and effective choice for general perfume mixing. The 99.9% grade is recommended when absolute purity and minimal water content are required.

3. Volume of 1 kg of Ethyl Alcohol (96%)

To calculate the volume, we use the density of 96% Ethyl Alcohol, which is approximately 0.805 kg/L (at 20°C).

  • Mass: 1 kg
  • Density: $\approx 0.805 \text{ kg/L}$
  • Volume = Mass / Density
  • $1 \text{ kg} / 0.805 \text{ kg/L} \approx 1.242 \text{ Liters}$

Therefore, 1 kg of Ethyl Alcohol (96% , Perfumer Grade, Low-Odor) is approximately 1.24 Liters.
