The leading authorities for worldwide standards across industries, the most respected third party labs, and regulatory organizations are all in agreement..
1. Salt Actively Absorbs Smells
Integra Boost is entirely plant based and will never alter your plants smell, color, texture or terpene profiles. Do not overlook this critical step when it comes to preserving the plants natural flavors and aromas. We provide the only 2-way humidity pack designed specifically for the medical cannabis industry, and commit to never carrying a salt based product. The salt giant Morton, has a page on their corporate site dedicated to demonstrating how salt can absorb even the most stubborn odors! https://www.mortonsalt.com/article/odor-elimination/ This a huge benefit in these applications, but isn't any effect you want to risk with a bin full of finished flower.
2. Aqueous-Glycerin > Saturated Salt
ASTM International
Designation E104-02: Standard Practice for Maintaining Constant Relative Humidity by Means of Aqueous Solutions.
"CAUTION - Saturated salt solutions are extremely corrosive, and care should be taken in their preparation and handling. There is also the possibility of corrosive vapors in the atmospheres over the saturated salt solutions."
Designation: D5032-11 Standard Practice for Maintaining Constant Relative Humidity by Means of Aqueous Glycerin Solutions
"The use of aqueous-glycerin solutions reduces the possibility of contamination of the material or corrosion of electrode systems which would be more likely to result from saturated salt or acidic water solutions."
3. Our Packs Don't Off Gas Acetone
An evaluation of off gassing characteristics was needed to demonstrate Integra Boost transfers pure water vapor through the active solution membrane. Bonner conducted the study.
"[Saturated salt pack] 62% RH 2-Way Humidity Control Humectant produces a significant amount of Acetone as a byproduct compared to Integra Boost 62% RH; which was Non-Detect (<1.0ug/l). Additionally, the [saturated salt] product continued to off gas giving a concentration of 13.11 ug/l at 18 hours."
4. Acidic Vapors Above Saturated Salt solutions Commonly Used for Control of Humidity
This is the IEEE study Volume 12 No 1, from March 1989. These studies repeatedly refer back to electrode damage, Cl vapors, Acetone off-gassing, and other negative impacts on both the material being tested and the lab materials used to conduct the tests themselves.
