STAR LABSolventless describes a process category. It does not establish purity, safety or a particular flavour.
A term about the process
In cannabis terminology, “solventless” generally refers to physical separation without an added extraction solvent such as a hydrocarbon. Rosin belongs to this category; its broad defining mechanism involves heat and pressure. This is a classification, not a preparation guide. [1]
Read “solvent-free” carefully
Do not assume that “solvent-free” and “solventless” communicate the same thing. One may be used as a claim about a finished material; the other describes a process category. Ask the writer to define the term and identify the evidence behind it. If a claim concerns a test result, the report should identify what was tested and the applicable reporting limit.
A claim-to-evidence checklist
| Statement | Useful supporting record |
|---|---|
| Process category | A clear process description and provenance |
| Measured composition | A matching batch report with methods and units |
| Aroma description | A dated sensory note with its source identified |
| Research conclusion | A study that actually tested the stated question |
How we use the word in this journal
We use “solventless” as a topic label and explain its meaning where it matters. We do not use it as shorthand for “chemical-free,” a health benefit or a universal quality ranking. Those would be additional claims requiring their own evidence.
When comparing descriptions, first identify what is being compared. A process name, a sensory preference and a contaminant result are not competing scores on one scale. Keeping them separate makes a comparison clearer and easier to verify.
