What “Purity” Really Means in the Carbon 60 Industry
What “Purity” Really Means in the Carbon 60 Industry
(And What It Doesn’t Mean)
If you’ve spent any time looking into Carbon 60 (C60), you’ve probably seen one word everywhere:
“Purity.”
99.5% pure.
99.9% pure.
Ultra high purity.
Sounds impressive — but here’s the truth:
Most of the time, that number is not telling you what you think it is.
When C60 Companies Say Purity The Reality is:
“Purity” = C60 vs Other Carbon Forms
When manufacturers talk about purity in C60, they are referring to:
The percentage of actual C60 molecules compared to other carbon allotropes.
Not contaminants.
Not solvents.
Not toxins.
Just different forms of carbon.
What Are These “Other Allotropes”?
Carbon can exist in multiple structural forms, including:
-
Fullerenes (C60) – the spherical “buckyball” structure
-
Other fullerene sizes (C70, etc.)
-
Graphite – layered sheets
-
Amorphous carbon – all different shapes and sizes.
So when a product says “99.9% pure C60”, it usually means:
99.9% of the carbon content is C60
0.1% is other carbon structures
That’s it, No transparency on other contaminants like solvents.
What That Number Does NOT Tell You
This is where things get misunderstood — or conveniently left vague.
That “purity” number does NOT tell you:
-
Whether solvents were used
-
Whether solvents remain in the final product
-
How the material was processed
-
Whether contamination was introduced during production
A product can be:
-
99.9% C60
-
And still Contain large amounts toluene, xylene, or benzene Solvents
The Solvent Gap
Traditional C60 production relies on hydrocarbon solvents to extract and refine the material.
That’s just how the industry has operated for years.
Why This Matters
If you’re only looking at “99.9% purity,” you’re only seeing:
Carbon composition — not production cleanliness.
Those are two completely different things.
What You Should Actually Look For
Instead of just “purity,” the real questions are:
-
How was the C60 produced?
-
Were solvents used at any stage?
-
Is there independent testing for residual solvents?
-
What is the actual particle profile and consistency?
Because:
High C60 purity does not equal solvent-free.
The Bottom Line
The Only Proven Company to use no solvents anywhere in their process and have no solvents in their product is, Greska’s Carbon 60.
“Purity” in the C60 world has become a marketing shortcut.
It sounds like safety.
It sounds like cleanliness.
But in reality, it usually just means:
“How much of this carbon is C60 vs other carbon shapes.”
And nothing more.
If you understand that distinction, you’re already ahead of most of the market.
