Titanium Dioxide - Hold Your Breath, It's Carcinogenic

There is an ongoing discussion in the scientific community about the latest regulation on titanium dioxide.

It's being classified as a carcinogen.

Hold Your Breath

Now, before you get all panicky, please note that titanium dioxide is not classified as a carcinogen when applied, but when it is INHALED.

Although it's not nearly as common to inhale titanium dioxide as it is to apply it (which we do in makeup, lotions, soaps, bath milks etc), this new classification does raise pertinent questions and concerns for formulators.

Example: As convenient as spray-on sunscreen may be, it may very soon become a thing of the past.

So unless you are accustomed to snorting your eyeshadow and foundation powder, this new classification is more a concern for producers and manufacturers. They may have need of additional filters and processes when handling the material.

You: Gee, Lise, it sure sounds like you are trying to downplay this. Science says it's a CARCINOGEN!

Yes. I know.

So are many things we are exposed to. There are carcinogens people enjoy on a daily basis such as red meat, alcoholic drinks, etc.

Anyone who smokes is well aware they are engaging in a health hazardous activity every time they light up.

My purpose in bringing you this particular bit of information about titanium dioxide (t-dioxide) is to give you some information.

Let me repeat that.


You know, stuff based on fact.

If we have information, we are equipped to make decisions based on knowledge instead of acting from misinformation and fear.

(I have a thing about that).

T-Dioxide in Cosmetics

Despite the latest classification of T-dioxide, I have no plans of discontinuing using it in my own make-up and cosmetics. My exposure is minimal and I don't snort my make-up. In short, I'm still cool with t-dioxide in my eyeshadows, foundation, etc.

Whether you choose to use t-dioxide in your own products or not is entirely up to you.

I'm just passing on information.

Do Tell

Do you use T-Dioxide in your cosmetics?

You know some people will start misleading the public and start avoiding certain products because of this. I guess the same people who inhale silica are the ones inhaling titanium dioxide.

Since this is a carcinogen via inhaling, what does it do when eaten. Some food products contain it. Will they have to change this too and warn people, eating it can cause cancer?

Hi Olivia- I know some people will start misleading the public. This is exactly why I posted this - in the hopes that people will look at the whole story and not just read the headlines. Titanium dioxide is safe when applied and when ingested. There is a difference in passing through the system (as it does when ingested), and getting stuck the lungs. Titanium dioxide is in practically everything. If you eat a daily vitamin pill, you are probably ingesting it. Almost anything that is white contains titanium dioxide, so I don't think it will be easy for people to avoid products containing it.
