The Truth About C60 Color: Why Some Oils Are Purple and Ours is Black

If you spend enough time researching Carbon 60 products, you eventually notice something strange.

Some C60 oils are deep purple.
Some are amber.
Some are nearly transparent.
And Greska’s Carbon 60 — is completely black.

So what’s going on?

Is one better than the other?
Does color actually matter?
And why do so many people in the C60 world avoid talking about it?

The answer starts with understanding what Carbon 60 actually looks like in its natural state.

Pure C60 Is Black

Solid Carbon 60 powder is black.

 Not purple.
Not violet.
Not translucent.

Black.

That surprises a lot of people because the internet has spent years associating “high quality C60” with purple-colored oil. In reality, purple coloration usually points toward a very specific type of processing history.

That history involves solvents.

Why Some C60 Oils Turn Purple

Many manufacturers use aromatic solvents — especially chemicals like toluene — to extract the C60 from other allotropes of Carbon. When C60 is dissolved this way, it produces the famous purple or violet appearance people often associate with fullerene products.

That color became so common that many consumers started believing purple automatically meant “pure.”

But that is not true.

Purple indicates that the C60 was dissolved using solvent-based processing.

Even if the solvent is later “removed", the impurities from the Toluene remain.

Why Greska’s Carbon 60 Is Black

At Greska’s Carbon 60, the goal was never to create a pretty purple bottle.

We avoid solvents entirely.

That changes everything about how the final product behaves and looks.

Instead of creating a molecular solution through solvent processing, Greska’s Carbon 60 uses a proprietary non-solvent process that creates a true suspension of ultra-high purity Carbon 60 in oil.

Because of that, the final product is black.

Black because suspended Carbon 60 itself is black.

That appearance reflects the manufacturing philosophy behind the product:

• no aromatic solvents

• no toluene processing

• no solvent-dissolution shortcuts

• true suspended Carbon 60

In simple terms:

• Dissolved C60 often appears purple or amber.

• Suspended solvent-free C60 appears black.

That is why Greska’s Carbon 60 looks dramatically different from many products on the market.
