First and foremost, it appears that unless one is prepared to make his or her own personal care products at home using all natural ingredients and use them within a short period of time, then we need a preservative.
Secondly, there seems to be countless opinions on the Internet about the safety of the preservatives used in our personal care products; some with little or no information to back up the claims, others so confusing that the average person is left with uncertainty, but no real increase in knowledge.
Through this blog post I will make an effort to present that which I have found from sources that seem to be credible. I encourage everyone who takes the time to read this blog to comment if they have any genuinely researched information that would be of use. I ask that opinion based on fear mongering not be submitted and opinion that has no valid back up (either for or against the use of preservatives) also be left out of our conversations. Please provide the source from which you have found your information in your comments so that we can all make our decisions about whether or not the source can be trusted.
Perhaps through this method we will finally get some closure on this continuously controversial topic; if only on an individual basis.
So which one is the lesser of the evils? And how do we know for sure?
I have not listed all of the preservatives or given information on all of them to start, In fact I’ve barley scraped the surface. However, I encourage everyone to feel free to provide information on ones that have not been discussed as well….the more information we share the better off we all will be!
We have heard a great deal of talk in the last few years about parabens (methyl, propyl, butyl, etc). I would first like to submit information I found on the European Union’s site (which seems to be a credible resource according to many others who have referenced it). Within the pages, in my understanding, it appears as though the studies relating to this preservative family are rather inconclusive for a couple of the types of parabens while others were deemed relatively safe for use. Here’s the link so you can decide for yourself: http://ec.europa.eu/health/ph_risk/committees/04_sccp/docs/sccp_o_138.pdf
Now, another trusted site, that of the David Suzuki Foundation, is obviously against their use in personal care and does even provide a link to the European Commission on Endoctrine Disruption. Take a look at the information provided there: http://www.davidsuzuki.org/issues/health/science/toxics/chemicals-in-your-cosmetics—parabens/
Another preservative group that has been heavily investigated in the last while is referred to as formaldehyde releasing preservatives.
Again, I went to my 2 favorite sources for this one. The European Union has outlined their research on the four main preservatives that have been categorized in this manner: sodium hydroxymethylglycinate, benzylhemiformal, imidazolindinyl urea and diazolindinyl urea, along with less detailed information about the others in this category. They strongly conveyed that these preservatives should not be in products in concentrations exceeding .2% in the finished product. Feel free to do your own evaluation: http://ec.europa.eu/food/fs/sc/sccp/out187_en.pdf
The David Suzuki Foundation provided a little information (that I could find) regarding these preservatives. I didn’t find information on all of the preservatives in this category. However, thye did reiterate the .2% information that was provided by the European Union’s site. Please feel free to read the materials from that site: http://www.davidsuzuki.org/issues/health/science/toxics/chemicals-in-your-cosmetics—formaldehyde-releasing-preservatives/
There is one other site that I visited that provided some reference to their resources. I cannot, however, say whether or not the site is entirely credible so I will leave that to you to decide for yourself. The link is provided here: http://personalcaretruth.com/2011/05/ask-the-experts-sodium-hydroxymethylglycinate/
When searching any preservative, or other ingredient for that matter, I would encourage the researcher to look diligently for opposing articles to whichever side you find most readily on the Internet. Let’s remember that the Internet is set up to respond to tags (keywords that make certain pages viewed more regularly). So if you want to really be an educated consumer then you really have to dig and determine what you think is the more valid argument out there. After all, you have to live with your decisions.
You will note that I have not directly provided my opinion on either of these because I don’t wish to try to influence the reader: I think that would be counter productive to my goals for writing this in the first place. As the conversation gets going I will simply attempt to provide opposing information to that which is presented here so that we can look carefully at both sides constructively.
Now, let’s get this conversation started!
