Vibrant Hot Pink Iron Oxide
Recently I came across a vendor selling what they call Pink Iron Oxide. The picture of it looks like Red 28 Lake, a bright fushia. The composition says Iron Red Oxide (CI 77491) & Titanium Dioxide (CI 77891). I don’t see how this is possible from those colorants so I reached out to the vendor, who seems like a third party vendor, to inquire about the accuracy. They stated that they can not reveal it but that the material is “treated” and that is what gives it the Hot Pink appearance. Has anyone ever heard of such a thing or seen a Bright Hot Pink Iron Oxide. The reason it is of interest is as we all know there are really no Hot or Bright Pinks available for the area of the eye.

Are you asking about something like this?

Something like that but that pic definitely looks like a Mica… Looks like old Imperial Red Pearl that contained Red 30 Lake…. But the website is similar looking with the sketchy ingredient list….. Just google Bright Pink Oxide by CDF Supplies… I have never seen or heard of a Neon Pink Iron Oxide… Not even with a “secreat” coating…. Curious to hear your thoughts….

I would like to know this as well. I’ve never seen an iron oxide pink, either in cosmetics or ceramics, and certainly not a brilliant hot pink. Their website isn’t as detailed on ingredients as I would like either.
Is it possible they ‘accidentslly’ left off another ingredient, and it’s really a cosmetic mica? Several suppliers I use have micas that vibrant.

Thing is, if that were the case, all colorful micas could escape detection that way. And if it’s a mica, the substrate (mica or phluorophagite) wouldn’t be integral to the trade secret, I doubt.
The fact that the website is very economical with the details is concerning as well. If this is a true breakthrough in iron oxide, they should be shouting it *from the creators*.
Colorful micas such as cosmetic or paint pigment ones are the only bright pink instances of iron oxide to my knowledge.. in ceramics that’s gotten by chrome + tin, and fritted to make a stain .
I’ll be curious to find out more.

To visit the product I was viewing just google Pink Iron Oxide by CDF Supplies… The main page says one set of Oxides and then the SDS sheet states 1 Oxide and TiO2…. No mention of organics…. Look at how bright that is… I inquired and they stated it is a “secret” as to how they process or coat it….. That may be so but if introducing another chemical or colorant into that process I would think the INCI nomenclature would have to be disclosed…. No one I speak to knows a Hot Pink Iron Oxide, especially allowed in the area of the eye !

It would be easy to tell if it’s a mica by getting a sample & weighing it vs an iron oxide.
Micas are fluffy, nowhere near the weight of an equal volume of oxide.
Though that wouldn’t tell what else might be in it.

I am doing that….. I just didn’t want to pay for the samples…. They don’t do freebies…. Its not Mica though…… Straight Iron Red & TiO2 they claim…..

I suspect this is a https://www.kolortek.com/ material. Seems a lot of re-sellers buy and re-pack their materials. I do also use some of their mica-based products in clear gel-based toothpastes.
I have samples of all of their products. Some are synthetic pigment based; but I have been surprised at some of the colours they have achieved useing mineral based pigments.
If you contact them, they will supply you the CoA/TDS/SDS. The couple I tried to click on said the documents are being updated.
