DMDM Hydantoin


'm going through my product stash and culling products that have it:

Generic Paul Mitchell The Conditioner
Lustrasilk Sheabutter Cholesterol
VO5 Strawberries & Cream
Suave Toasted Vanilla & Sugar

Urea (Imidazolidinyl) & DMDM Hydantoin
These are just two of many preservatives that release formaldehyde (called “formaldehyde donors”). According to the Mayo Clinic, formaldehyde can irritate the respiratory system, cause skin reactions and trigger heart palpitations. Exposure to formaldehyde may cause joint pain, allergies, depression, headaches, chest pains, ear infections, chronic fatigue, dizziness, and loss of sleep. It can also aggravate coughs and colds, and trigger asthma. Other possible side effects include weakening the immune system and cancer

    While it's probably true this can happen, I believe I remember that these quantities have to be constant, high (I mean, really high) concentrations. The same informational warning happens with aspartame. Aspartame turns into "formaldehyde" in your digestive track, which can lead to all of the problems above.

    The FDA determined that even with people drinking large quantities of diet sodas every day, the risk was still low enough that they wouldn't remove it off the market. I my opinion, the same though process applies to these products. The amounts are so small the chances of these side effects happening are low.

    Yikes! Doesn't formaldehyde also act as a hair relaxer? :confused1: I'm sure there isn't much in the products I use that do have this but it's the last thing my wimpy waves need.

    Yeah, I'm not too worried about this one, either. While ingredients like urea and DMDM Hydantoin are not the healthiest of substances, they are added to products to keep things like mold, bacteria, and yeast from growing in the bottle and spreading to us, the happy users. Any reading I've done on this topic indicates that there's not enough of these preservatives in any given product to pose serious harm.

    This also strikes me a little like the lead in lipstick scare of a few months back. Yes, it's in there but not in lethal quantities.

    Your systemic exposure will be very low given that this is a product applied to your hair. If I were using a lotion over my whole body everyday containing formaldehyde donors, that might give me pause. Here's an abstract on DMDM Hydantoin from the peer-reviewed International Journal of Toxicology.

    Final Report on the Safety Assessment of DMDM Hydantoin

    Published in: International Journal of Toxicology, Volume 7, Issue 3 1988 , pages 245 - 277

    Abstract
    DMDM Hydantoin is a preservative, which is used in cosmetic products at concentrations up to 1%. This ingredient is a formaldehyde donor containing up to 2% of the free aldehyde in equilibrium with the hydantoin. When 14C-DMDM Hydantoin was applied to the middorsal area of Sprague-Dawley rats, more than 98% of the recovered radioactivity was confined to the dose site. The LD50 dermal and oral toxicity of DMDM Hydantoin was greater than 2 g/kg. No significant toxic effects were noted in a subchronic oral toxicity study. In skin irritation studies using product formulations, results ranged from nonirritating to moderate skin irritation. At most, transient minimal irritation was noted in albino rabbits treated with DMDM Hydantoin formulations. The mutagenicity of DMDM Hydantoin formulations varies in accordance with the test system. The ingredient was not mutagenic in one Salmonella/microsome assays but was in another. Both positive and negative mutagenic activities were reported when DMDM Hydantoin was tested in the L5178y TK± mouse lymphoma assay. The ingredient was mutagenic in the chromosome aberrations and unscheduled DNA synthesis assays but was not mutagenic in unscheduled DNA synthesis and DNA strand breaks/crosslinks assays. A comparison of Ames test results from studies of DMDM Hydantoin product and formaldehyde indicates a similar number of revertants per formaldehyde equivalent. In clinical studies, skin irritation ranged from none to observations of intense erythema and edema when various formulations containing DMDM Hydantoin were applied. DMDM Hydantoin formulations did not induce sensitization in some clinical studies. DMDM Hydantoin formulations were neither phototoxic nor photoallergenic. Use of DMDM Hydantoin at its current concentration of use in cosmetic products would not expose the consumer to levels of formaldehyde above the limit previously considered as acceptable in cosmetic products. Based on the available data included in this report, it is concluded that DMDM Hydantoin is safe as a cosmetic ingredient in the present practices of use.

    Hmm, just checked and the products I've used that do have this were underwhelming. I was blaming the polyquats (seems that PVP and VA/VP work best for me) but now I wonder if DMDM Hydantoin may be the culprit. Of course, with my luck, 99% of you who do use polyquats w/DMDM Hydantoin get fabulous results. *sigh*

    DMDM Hydantoin is used in concentrations < 1% so I doubt it would have an effect on the performance of a hair product.

    You may be right but for products I've used that have this (especially high up on the ingredients lists), definition wasn't the greatest. :dontknow:

    I know that this ingredient is gross and why it's gross, and I do think it is quite gross. However, I choose to take an informed risk and still use some products that have it.

    Presented with two products with the exact same result, one not having this ingredient, I would choose the one without this ingredient. Unfortunately it isn't that easy for me, at least yet.

    I am sort of starting to wish I lived in a big refrigerator, so that nothing would need so many preservatives.

    Oh my goodness.....just one more thing that I have to look out for.........I sometimes feel like a scientist. I am finding that my hair does like glycol, but not cones. This might be too hard for my old brain!

    don't you know some women would rather die than sacrifice their beauty regimen????
    I used to think microwaveable popcorn was safe, but recently a man died from it.
    Had the FDA posted a warning on the packaging stating that eating too much Partytime Popcorn could cause death? Nope!

    keep doing what you're doing SBB. those who argue about the trace amounts will have to deal with their decisions.

    I have so many other good alternatives, using these products even with small amounts of this stuff, is totally unnecessary.

    Haven't you heard? Living can cause death! Better stop doing that, too. Breathing (or lack thereof, for that matter) can kill you, too. I figure I'm gonna die sometime, why worry about everything I might come in contact with? And it's not about sacrificing a beauty regimen...it's about living in fear about every product that might contain something bad.

    If someone wants to avoid it for their own reasons then so be it...don't knock those of us who don't.

    A ton of my products have DMDM Hydantoin and related preservatives, but it doesn't seem to bother me as much as parabens.

    This is an informative thread. It does not knock anyone's use of products containing DMDM hydantoin that I can see. If you're feeling feeling defensive about it, that's your own lookout.

    Hmm...let's see. Saying women would rather die than sacrifice their beauty regimen? Could be just an opinion...could not. I'm over it. Gotta go smoke a pack. And eat some charred beef. Add it to the fires of hell I'm already burning in.

    Yeah, I'm of the opinion that pretty much anything in large quantities is bad for you, so instead of getting worried, I just remember "in moderation."

    These chemicals have been in products for years, and yet each generation seems to live longer than the generation before. In spite of all these chemicals, we seem to be doing okay.

    Granted, if I was slathering this all over my body, like one poster said, I might be more concerned.

    I love drinking Diet Coke, but again it's in moderation.

    Excessive anything can be bad and that includes things that are generally considered good for you.

    I say Live and Let Live. I do think it's a good idea to inform us of this, because I'm all for "informed consent." Some people may decide to not use these products and that's okay too. And those of us that do decide to use them, then at least we were informed.

    ...which I just found out the hard way.


    On vacation in Phuket, got sunburned, bought some of the sunburn gel here.... had a very bad reaction to it. Not only did it increase my pain, my face is swollen really bad, especially around my eyes. Active ingredient... DMDM Hydantoin.


    Post like these are good ones. Don't knock them because not everyone is able to use the product. Also, I've read, prolong use can make you developed an allergy to the product.


    Just wanted to add.... this stuff causes some people some really bad skin irritations. In one report I read it caused irritation in 20% of the people tested in America. Read up on this stuff and see how bad it really is.
