Is Silica in Cosmetics Dangerous?

by beautifulwithbrains
why silica in cosmetics is not dangerous

Word on the beauty streets is that silica’s trying to kill you.

It’s the latest ingredient to be accused of giving you silicosis and all sorts of nasty diseases. Once the rumours start, everyone adds its fair share of gossips and side effects.

We don’t do gossip here (that’s why I won’t go into the whole Erica vs Coastal Scents controversy that’s on everyone’s mouth atm). We do science. And when there’s a scare like this, it’s to science we need to turn to (even if it isn’t as funny as watching two people argue).

So, what does the science says about silica in cosmetics? Is it really killing you or not?

What is Silica?

Silica is one of the most common minerals on earth. You can find it in sandstone, clay, granite and even in parts of plants and animals. You can also make it synthetically in a lab.

You get some of it when you eat fruits and vegs and it helps keep your joints flexible, your bones and teeth strong and your skin glowing.

Why Is Silica Used In Cosmetics?

Several reasons:

So, What’s “Bad” With Silica?

Well, silica can cause silicosis. For those who aren’t familiar with it, it’s a lung condition that causes inflammation in the lining of the lung. Overtime, lung tissues become thickened and scarred.

The symptoms are:

  • Blue nails
  • Chronic dry cough
  • Loss of appetite
  • Shortness of breath
  • Sleeping problems

Scary stuff, huh?

But, and this is an important but, the type of silica that causes silicosis is crystalline silica. It’s dangerous for you only when you inhale way too much of it. So, if you were a miner not using a mask, you’d do well to worry. But, if you only use cosmetics?

What Type Of Silica Is Used In Cosmetics?

Hydrated silica. Aka silicone dioxide.

This is a solid spherical powder that doesn’t interact with your lungs the way that crystalline silica does.

So, if you’ve been wondering whether you should go out and buy a jar of MUFE HD Powder, do it safely.

The Bottom Line

This is what happens when well-meaning people read something online without looking at the science first. They get scared, warn others in good faith and cause an unnecessary stir. Unless you’re allergic to silica, there’s no reason why it shouldn’t be in your cosmetics.

Do you use cosmetics with silica or has this whole controversy put you off?

Nikki: you’re welcome. I guess lots of poeple that know about the controversy tend to take sides and forget about the actual cause of the problem, ie whether silica is dangerous or not. I know I got a bit sidetracked at first too, but now the whole thing has gotten blown up of all proportions, it’s ridiculous.

Dao: Silica is one of the top oil absorbes and really improves the staying power of their cosmetics as well as their smoothness and spread. The only rason not to use it is if you’re allergic to it, but like you pointed out, that’s a rare case.

Jnie: thanks. I couldn’t agree more, things have completely been blown out of all proportions *sighs*

What are the allergic reactions?

I usually don’t use cosmetics, but decided to use Regenerist contour and lift at-home treatment, which contains silica.

Within a couple of hours my heart started racing. May be a coincidence.

What do you think?

Reply
beautifulwithbrains March 6, 2009 - 12:31 pm

Well, symptoms of allergic reactions are usually rashes, redness, breakouts and irritation. Silica can cause nausea but only if inhaled or ingested. I highly doubt silica in cosmetics can make your head spin, it’s probably just a coincidence. I would recommend consulting your physician. He/she will be able to tell the actual cause of your symtoms.

You get your product safety information from an industry trade group that has previously lobbied against safe cosmetics legislation? Really?

http://www.cosmeticsinfo.org/ is run by the Personal Care Products Council.

See https://en.wikipedia.org/wiki/Personal_Care_Products_Council

BTW, crystalline silica is just another name for sand or quartz, and it’s not good for your lungs, even in small quantities. The more “grounded” (you meant ground) it is, the more likely it will be inhaled in powder form.

According to http://www.safecosmetics.org/get-the-facts/chemicals-of-concern/known-carcinogens/
“Crystalline silica is widely used in lipsticks, lip gloss, eye shadow, eye liner, foundation, sunscreen, lotion and shampoo.” and “NIOSH raises concerns about lung cancer in animals exposed to crystalline silica; and this chemical can target eyes and the respiratory system through inhalation, and skin and eye contact.” So it doesn’t even have to be breathed in to be potentially harmful.

Your attitude seems to be the opposite of the precautionary principle. You do a disservice to your readers.

Safety First, yes, really. There’s nothing wrong with lobbying against a legislation that would massively increase costs to companies and prices to consumers WITHOUT making products any safer.

My sources may be biased, but at least they get their information from scientific studies. The EWG and Campaign For Safe Cosmetics are just as biased, but get their information by twisting those studies. For example, they claim that just because something is toxic at 100% concentrations, they’re dangerous at 1%, too. They say that just because something is harmful when ingested, it is harmful when topically applied, even though very few substances can penetrate through skin, and whoever says otherwise obviously was paying no attention at science class in school. They say that because a substance gives cancer to rats, it will automatically cause cancer in humans, too. They don’t take into consideration dose, method of exposure, etc, which is why reputable scientists ALWAYS refute their conclusions. In short, the EWG and Campaign For Safe Cosmetics are NOT reliable sources. Far from protecting consumers, they’re scaring people into giving them money to fight a made-up cause.

The study you cite about silica again was performed on animals. Do you have any scientific proof that, in the tiny amounts used in cosmetics and the way people use those cosmetics, causes harm to human health? Because I haven’t come across any yet. You are more than free to avoid this ingredient, but that doesn’t mean it’s a killer.

I use the precautionary principle when it makes sense to do so. Do you know that cars kill more people than planes? And both kill more people than cosmetics with silica? Yet, I bet you still use cars all the time. It never fails to amaze me how people can underestimate, and take, big risks like car accidents all the time, and yet they make a big fuss about cosmetics, when no one yet has died for using cosmetics with silica, parabens, etc. If putting things in perspective, and telling my readers not to worry about non-issues is a disservice, than yes, I’m guilty as charged.

Touché, Gio! Years ago, when I wanted to make my own bath and body products and started researching ingredients, at first, all I could find was DON’T USE, IT’LL KILL YA….basically that was the gist. I persisted in finding info from both sides to assist me in making educated decisions; I’m tenacious.

There is so much fear-mongering going around and then, with good intentions, others spread it without understanding due to lack of comprehension. Research, RESEARCH, R-E-S-E-A-R-C-H ! Use some common sense too. I’m glad I happened upon your site; you use common sense reasoning and EDUCATE yourself rather than becoming a follower of falsehoods. There are generally 2 sides to everything and one must not only read but also discern if the person or entity has something to gain from the position they hold and are promoting. Often, maybe not always, those who follow falsehoods ‘attack’ rather than present out information for the betterment of the one in which they are (in their mind) educating.

LOL, citric is a prime example of fear-mongering and I laughed when I came across all the negatively surrounding it. In fact, I’ve shared the info with others, not to spread the falsehood but as an excellent example of how things can be blown way out of proportion. Yes, due to huge demand, and deriving it from fruit cannot keep up with production needs, demands it’s produced from–I’m sure you know–black mold. Oh my goodness, I’m gunna die 😊. “A variety of yeasts and molds make citric acid, but Aspergillus niger, a mold that belongs in the same family as penicillin, is used for large-scale production.” (https://www.livestrong.com/article/477815-how-is-citric-acid-made-where-does-it-come-from/)

We all know that penicillin was accidentally discovered; this first antibiotic was originally named “mould juice.” 😊. While we don’t want to EAT mold, some molds do serve us well. In the time of penicillin’s discovery people were dying due to scratches if it became infected. Can you imagine dying from an infection due to a dental procedure or a cut?

One isn’t consuming the black mold, Aspergillus niger, if they eat foods or drink beverages with citric acid derived from black mold. No more than if we were to eating a human being if citric acid were derived from people. Yes, that’s right; our body actually produces all the citric acid we need. We don’t need to ‘specifically’ consume things that contain ‘citric acid,’ which is in almost everything. Our body synthesizes citric acid from sugars that converted from carbohydrates. Carbohydrates are broken down into sugars [that’s why they’re not good for diabetics, complex charbs aren’t as bad due to slow and steady charb to sugar conversion]. Then these sugars are converted by the body to acetyl
coenzyme-A. CoA is then turned into citric acid and the energy cycle begins. The process is a bit more involved (https://www.chemistry.elmhurst.edu/vchemook/600glycolysis.html) but that’s the gist. So, when man finds a way of deriving citric acid from humans (many humans out there so, WOW, that’d be a boat load of citric acid) we’re not eating humans no more than we’re consuming the black mold (Aspergillus niger) by ingesting products containing man-made citric acid vs the real deal from citric fruits.

The products I make for our family’s personal use and to gift to others are far more beneficial to my skin than commercial junk; called junk only because they contain multiple constituents I prefer not to use on skin or in my hair. Because I use them and share them (eventually will market them ‘small-scale to offset my crafting costs) I want to be certain they don’t aggravate my and my children’s severely sensitive skin and allergies. I’m 58 years young and I had to quit using commercial soap at age 15 because my skin hated those detergent bars. I love using soap (lye soap) and my husband couldn’t quit commenting on “there’s no comparison between store soap and your (my) soap” and “commercial soap has nothing on your (my) soap.” Lye soap is another thing that is gonna rot your skin off…….don’t even get me started 😊

THANK YOU FOR YOU SITE and USEFUL info. Once again, Touché.

I am really getting annoyed by people getting in a tizzy becuase of things like this. People make up their minds and spew out a bunch of “facts” without actual knowing what they are talking about. From sunscreen to talc and parabens. I think its time somone steps up and clears up this paraben nonsense. Dont wear paraben makeup! but its still okay to eat blueberries and other plants even though they naturally contain parabens.

beautifulwithbrains July 15, 2011 - 6:38 pm

Ryan, it’s a shame people are so easily scared and stop buying perfectly safe products instead than looking up the scientific facts. They’d realise then that there is really nothing to be worried about. I hope this article will help set the record straight on this issue.

ben November 15, 2012 - 6:07 am

Actually, parabens are broken down in the stomach. Eating them is fine. It’s through the skin that’s the problem.
I’d always suggest caution with any chemical that’s new and untested. I avoid all minerals too because they aren’t soluble and IF they get in your lungs, they MIGHT stay there.

Reply
beautifulwithbrains November 15, 2012 - 10:02 pm

Ben, there is no proof that parabens are bad for you when applied topically yet. There is some proof that they can penetrate skin but the body gets rid of them within 3 days so their accumulation shouldn’t be a concern.

As for minerals, I think that they’re bad only when inhaled in large quantities. If you apply it carefully, the minimal amount on silica you put on your skin isn’t a problem.

I understand that not everyone is comfortable using these ingredients and may like to wait until we have further information, but we shouldn’t become paranoid either. After all, everything in concentrations high enough can be harmful.

Reply
ben November 15, 2012 - 10:19 pm

It’s a personal choice. Like many things in life.
If you use parabens regularly then they will be constantly present.
Lung cancer is more and more prevalent. Who knows what causes what. Evidence can take years or decades to appear.
In my opinion, caution and common-sense is the best policy when it comes to health. But I can understand people preferring to be care-free.

Reply
beautifulwithbrains November 16, 2012 - 8:18 am

Ben, I do agree that in the end it’s a personal choice but I don’t see why people who decide to trust science are care-free. If the body gets rid of parabens after 3 days, then their levels are always gonna remain stable and too low to cause any harm. Further studies on parabens are certainly needed but all the doctors and dermatologists I’ve talked to so far believe they aren’t bad and no study has as yet proved they are. Until then, I’ll keep using them.

Cigarettes cause lung cancer. Air pollution causes lung cancer. Even if some minerals caused it, you’d have to be exposed to huge quantities of them. The crap we breathe (and eat) every day will kill us off sooner.

We should all exercise caution when it comes to our health, but we shouldn’t be paranoid either. After all, everything can be bad in large enough doses. For instance, in high amounts, Vitamin C is toxic. Does that mean that we have to stop using that too? All plants and water contain substances that can be toxic and carcinogenic but because they are present in them in such small quantities our body manages to get rid of them so they won’t harm us. In the end, it’s the quantity that makes the poison.

ben November 16, 2012 - 2:03 pm

Yes, you already said all that.
It’s not paranoid to value your health over your beauty products. It’s common sense. But if you are exposing yourself to a load of other crap in life (care-free), then you may as well breathe in little bits of rock and carcinogenic mineral compounds like titanium dioxide too. Go for it.

beautifulwithbrains November 16, 2012 - 10:33 pm

Ben, there’s no need for such sarcasm. I agree with you that your health is more important than beauty products. My point is that parabens, silica and other ingredients haven’t been proven to cause cancer yet and so I don’t see any reason to avoid them. If a link should be found, I will be the first to stop using these ingredients and tell my readers to do the same.

If we were to avoid all potential dangers, we couldn’t even cross the street or take a plane, for instance. It’s up to each one of us to assess whether a risk is worth taking. As for me, if science tells me something isn’t harmful I’ll use it, and I don’t believe I’m being carefree for doing so. After all, if we can’t trust peer reviewed, double blind studies, what can we trust?

What if you are sifting silica all over your house for pest control, on your bedding, blankets and sheets. Wouldn’t you be inhaling this dust and get ill?

Reply
beautifulwithbrains October 17, 2011 - 6:21 pm

Angel, I’m afraid I don’t know what type of silica is used for pest control so I’m not sure what to say. Do the instruction of the packaging mention anything about it? In general, though, it’s the dose that makes the poison, so using it for a long period of time may be harmful for human health. But as I mention, my knowledge of silica is limited to the type used in cosmetics, sorry.

I’ve always wondered about silica in cosmetics. I used to work with the bridge crew for my state’s department of transportation and we had to wear masks to cover our face because of silica. If it was used in the building of anything and then it’s disturbed it can ’cause a huge medical issue, not just mining.
Since then I’ve been overly cautious of anything containing silica because of that fear (some of the training videos were not pretty). So it’s good to know that the silica in cosmetics/beauty products is safe to use. Thanks for the awesome post!

Hello.

excuse my English. I’ve been using for 2 years HairSoReal (web: http://www.hairsoreal.com/contact.cfm), microfibers conceal baldness. I have recently noticed that contains silica, but I find information on whether using crystalline form or microspheres. As a powder is probably breathed this fiber rods occasions, my question is, all the cosmetics industry uses non-crystalline form? for both forms the “silica” generic term used for? Thank you

I have to dissagree with the statement about miners not wearing masks/not needing them. I can’t speak for miners, but silicosis is very real for anyone working with clay, ceramics etc. most ceramic studios have osha certified ventilation systems, when I worked in the studio processing dry clay, I had to wear a special respirator and everything. One thing that concerns me, cosmetic labels don’t say what kind of silica is used. How can you tell if it’s the safe version or not?

Reply
Gio April 23, 2015 - 1:36 pm

Potter, I did say that miners do wear masks. They need them. I also said that UNLESS you are a miner, you don’t need to worry about silica. Saying unless you work with huge quantities of silica, you’re not a risk would probably have been better, as there other professions that may make workers at risk of contracting silicosis.

But the point remains, that silica in cosmetics is not dangerous. Silica microsheres is the type of silica approved for use in cosmetics. I don’t think companies can use any other type of silica without getting into trouble., Contrary to public opinion, it is illegal to add toxic stuff to cosmetics.

Pretty much anything that’s written in that article is twisted to suit their agenda. Like the claim that the EU has banned more chemicals from cosmetics than the US. True, but do you know that those chemicals are NEVER use in cosmetics anyway? What’s the point of banning something if no one uses it? You see how easy it is to scare people?

Hello,
Just read this post and I think it helped.
I recently switched deodorant and my armpits completely broke out into a rash almost looking pimple like but not quite. It spread down my arm and a bit down the side of my chest. I looked at the ingredients on the new deodorant and compared to the deodorant I had previously been using. One of the ingredients contained in the new deodorant was silica. I did a bit of research on the ingredient and many websites said that it was a “known skin irritant”. Do you think that the Silica could have caused the reaction?

Reply
Gio April 14, 2018 - 8:59 am

Kennedy, anything, even the gentlest of ingredients, could potentially cause an irritation to someone. There are people who can’t use water, for example. If that’s the only new ingredient in your new deodorant, I’d say that’s the culprit. Or are there any other differences between your new and old deodorants?

Reply
Kennedy April 23, 2018 - 7:25 pm

The old deodorant, and the one I have gone back to, is the Olay Secret Deodorant with I have never reacted to before. The one I just recently broke out using was labelled as an all natural ingredients deodorant, so basically all of the ingredients were different. Most of the ingredients were plant derived, some of the ones I can remember being corn and seaweed derived. However, doing more research I looked into another deodorant that I react to, Dove Stick Antiperspirant Deodorant, which also contains Silica.

I think silica is the issue, I can’t see anything else that would have caused it (unless I am missing something). Silica was in the natural deodorant.

Sarah July 20, 2018 - 4:59 pm

Check to see if the natural deordorant has baking soda. It is common for baking soda to cause irritation. Also you could be having a reaction to a particular fragrance or particular essential oil. I’m not saying it is not silica; but, reactions to baking soda, fragrance, and essential oils are more common. Without a proper allergy test you can’t know for sure. Also, it could be the pH of the product that is causing issues with your skin. Some deordorants out there are very alkaline.
