Make Up For Ever; HD Powder - Is it toxic?

[Cyanide.Candy]

Ok, now I happened to come across this link regarding Silica, in context to MUFE's High Definition Powder (Which is made of 100% Silica) and it made for an interesting read.

Now I'm not out to scaremonger or anything of the sort, obviously I'm not passing any judgement yet til I know all the facts, but I think it's worth the read.

I was just about to purchase the HD Powder til I came across this. It's really made me think twice now and I don't know if I want to actually use it now.

NIOSH - Silicosis: Learn the Facts!

Can anyone shed any light on the above, or have any relevant info?

First of all if it was toxic it wouldn't be sold anywhere.
Cosmetic companies are very careful with what they use in their makeup and I don't think MUFE is willing to ruin its reputation by releasing a dangerous product.
Also, if you check the wikipedia it also talks about another kind of silica which is harmless.

Silica is not toxic. It is a relation to silicone, dimethicone, etc. Just like dimethicone is a liquid that is used as a primer, silica is like the dry form. Its the ingrediant for a smoother finish. The over 40 set should look for this ingrediant in powders as it will not emphasize not so fine lines.

I understand the confusion and your concern.
Your article had me worried for a moment there too.

So I did some checking up.

Silica itself seems to be harmles. You can find it in every tube of toothpaste. So what's the problem: It's the way we use it. If we inhale it it could be harmful.

I don't see us inhaling the same amounts of this powder as construction workers do. But then again, when it comes to cosmetics we always want to be on the safe side. I'm using Chanel's new cristalline powder, and it's very similar to the HD powder because it's main ingredient is silica.

I did some research and one of the links even mentions that we should be careful when we inhale talc... (which is the base for every powder). If you read the links, I think that - as with every cosmetic - you'll conclude that normal safe use , is not going to be any problem what so ever.

hehe

I take silica supplements for hair, nails, and skin.

I am not dead... yet.

the article you posted is about crystalline silica being inhaled.
unless you decide to blow lines of the powder, i assure you that youre perfectly safe.

 

[HeavenLeiBlu]

Whew, I was alarmed for a second there... I just set my daughter's makeup with this stuff today.

That article does refer to the same substance but in a highly micronised form. MUF's HD powder is denser but is still sold on the basis that it is used externally and in small amounts. This is the MSDS sheet that accompanies this product which I obtained from a stockist:

Interesting. I have been feeling increasingly breathless recently, and cannot find a good reason why. I have tried to think of anything that has changed, and my loose powder was one thing I changed at a time which coincided with this feeling. I recently switched from BE mineral veil to MUFE HD powder. I noticed that it is so finely milled it sort of 'clouds' around my face and some goes into my nose every time I use it. I am not saying this is the cause of the feeling but did not want to rule it out. Here is a summary of the info I have been able to find:

* Silica is not actually toxic, it is stable and non-reactive, but in its crystalline form, if inhaled, it can cause lung fibrosis/cancer/all sorts of bad things!

* MUFE HD powder is NOT silica in its crystalline form, it is what is called amorphous silica.

* The risks from inhaling amorphous silica are much less than those of inhaling crystalline silica.

However, I found the following link: Health hazards due to the inhalation of amorphous ...[Arch Toxicol. 2002] - PubMed Result

(Unfortunately you can only read the abstract).


And this: Possible Health Hazards from Different Types of Amorphous Silicas

Now I do not know if the HD powder is the same as the stuff they are looking at here, and if it is, at least it looks like it is not going to cause the same irreversible damage that crystalline silica does. However I am going to stop using the powder and see if things get better, as it does appear that amorphous silica can cause immediate and short term inflammation. Perhaps this is why I am struggling to draw breath, perhaps not.

If anyone is interested I will keep you posted on whether stopping using the makeup helps!

The question is: Can amorphous silica go into our lungs and with the moisture in the body, overtime (maybe years and years) become crystalline slilica.

 

[aloevera]

That is a good question! I had the impression it was fairly stable, I don't know by what process amorphous can turn into crystalline... silica range : use of silica, range of silica, manufacturing process here it says that non-crystalline ones can all be converted into crystalline forms when heated to high enough temperatures, and from reading stuff elsewhere it looks like in its anhydrous form it can trap a fair bit of water, but I have not seen anywhere that this could convert it to its crystalline form. I don't know how hydrated the silica in the HD powder already is, though.

Converting an amorphous material to a crystalline state is often done by heating it. It seems highly unlikely to me that amorphous silica in the body would crystallize.

As a chemical engineer/physical chemist; silica is pretty low on the list of things I'd worry about in my makeup.

as a biochem major, i with a significant level of confidence will say that its almost impossible for you to:
a) transdermally absorb enough of the HD powder to build up a toxic level of silica in the body ..... ill go as far as to say, you wouldnt be able to transdermally absorb a toxic level of it even if you sat in a tub of it for a week.
b) even if you inadvertently absorbed that much silica via transdermal, ingestive or inhalation pathways, your body would excrete or get rid of the silica before it would have a chance to crystallize and become harmful.
c) the amount of heat and time it would take for silica to crystallize on its own, would be on an industrial level. if you were that hot, you would surely not be alive to be poisoned by the resulting crystallized substance.
d) even if you did have crystallized silica in your body, your exposure would have to be for weeks, months, years to build critical mass and damage for it to be fatal.

basically, the powder is fine.

fine for normal intended use... i still would not snort it or let your babies roll around in it... but for setting your foundation, its a perfectly safe product


also wanted to point out that alot of loose and pressed powders, especially those for oil control contain a good percentage of silica.

If its dangerous inhaling then its dangerous buffing it on the skin. Dangerous is dangerous. However it won't stop me from giving it a whirl. I'm natural in 90% of my life and dammit I'm gonna enjoy my cosmetics. All the chemicals in all this makeup we use aren't good for us, just like the air we breathe isn't. *sigh* All we can do is make our own best personal judgement and enjoy life!!
