Why Blend Instead of Choosing One Solvent
Rather than committing to a single solvent, many licensed facilities run pre-blended mixtures of n-butane and propane to land between the two solvents' properties. The rationale is to combine n-butane's cannabinoid recovery and textural stability with propane's lower-temperature recovery and terpene-forward extraction, without running a system at propane's full vapor pressure.
A 70/30 blend, 70% n-butane and 30% propane by volume, is the most commonly referenced ratio in commercial hydrocarbon extraction, with a boiling point around -13°C. Ratios like 80/20 and 90/10 serve operators who want most of propane's cold-recovery benefit while staying closer to n-butane's pressure and handling profile.
Getting the Ratio Right for Your System
Blend ratio is a formulation decision that should be validated against your specific equipment's pressure rating and your facility's engineering documentation, not selected by trial and error. A blend that is safe and effective in one system's pressure vessels may exceed the rated tolerance of another.
Pre-blended solvent also removes a variable that on-site blending introduces. When ratio consistency is controlled at the fill rather than at your facility, run-to-run reproducibility improves and your batch records get simpler to defend.
Our team works directly with your facility to match blend ratio to your equipment rating and target product. If you need a ratio outside the standard three, talk to us about your supply program.
Frequently Asked Questions
- What does a 70/30 blend mean?
- A 70/30 blend is 70% n-butane and 30% propane by volume. It sits between straight n-butane and straight propane in boiling point and vapor pressure, combining n-butane's yield and stability with propane's lower-temperature, terpene-forward extraction.
- Which blend ratio should I use?
- It depends on your equipment's pressure rating and your target product. 70/30 leans terpene-forward for live resin and sauce; 90/10 stays close to n-butane's stability and pressure profile. Validate any ratio against your system's engineering documentation before production.
- Can you supply custom blend ratios?
- Our team builds supply programs around your production volume and equipment. Contact us with your target ratio and system specifications to discuss options.
