Parabens – Part III (More Info Still!)

Here we are, back again to the parabens.  It may seem like this is a never-ending debate.  But that is fine with me.  Further debate leads to further investigation.  And further investigation may eventually lead us to some solid answers.  I’m a scientist.  I like solid answers, but truth is ever evasive.  As long as everyone is different, there may never be a final answer.

So let’s take a look at the latest information.  It comes to use from the Scientific Committee on Consumer Safety (SCCS) through the European Commission.  It is an independent non-food scientific committee with no financial gain from industry for their work.

The “Opinion on Parabens” paper can be found here: http://ec.europa.eu/health/scientific_committees/consumer_safety/docs/sccs_o_041.pdf

It is some 35 pages long and gets deep into scientific lingo.  So I will try to sort it out for you.

Most parabens are OK.  Methylparaben and Ethylparaben are restricted to 0.40% by weight while Propylparaben and Butylparaben are restricted to 0.19% by weight.  Oh, if more than one paraben is used, they are restricted to .80% by weight in a formula.  Sound good?  Most cosmetic/personal care/personal lubricant formulations do not ever use them at that high of a level.  The most I have ever seen is around 0.40% by weight when using three of the four.

So looks like we are home and dry?  No.  We haven’t really even reached for a warm fluffy towel yet.

The Commission wants more data.  The rat and mouse models (yes, animal testing) do not have enough correlation to a human model.  They are asking for more in vivo human tests.  (In vivo means testing on a live creature, in vitro is testing in a petri dish.)  There are a few other parabens which have not been tested, but no one uses those in and personal care application.

It appears that parabens whether applied subcutaneously or orally rapidly metabolize into PHBA which is found in all plants and is expected to naturally occur in humans.  It is quickly passed through the system through our urine and faeces.  However, intact parabens have been found in the urine and/or serum and seminal plasma.

That is why the SCCS set the above stated limits, because they need more data.  They set the threshold much higher than the Industry’s recommendation.  Enough animal tests, we need to test on humans.  Pretty scary, huh?  Want to be a human test subject?  I would!

Bottom Line Straight from the Report: 

With respect to the safe use of parabens as cosmetic ingredients, concern was expressed as to the potential endocrine modifying effects of parabens of higher chain length including Propylparaben, Butylparaben and related iso compounds. Benzylparaben was also of concern. Based upon the currently available in vitro data and in vivo rodent test results, the SCCS agrees that the estrogenic properties displayed by parabens appear to increase with increasing chain length. Nevertheless, the SCCS stresses that the displayed potency levels remain about 3 to 6 orders of magnitude lower than the potency of the positive controls.

So the jury is still out, but the deliberation is drawing near a close.  We should have more definitive answers in 4-5 more years.  Stay tuned…

Happy New Year! (And it looks great!)

Here we are again.  Another year older and deeper in debt.  But, most of us are still working, are relatively healthy and get enough to eat.  Yay us!

I get comments from folks that my job must be a non-stop thrill-ride.  That I must have more fun on a Monday morning than most people do all weekend.  And they are mostly correct.  However, there is also great sacrifice and dedication that goes into my work.  Do you think I would give anyone a product to try that I haven’t used myself?

No, I wouldn’t.  And I wouldn’t expect anyone to try anything that hasn’t been tested on myself or one of my lab slaves.

Let me tell you about sacrifice.

There are a couple of major trade shows going on this week and weekend.  There will be toys, lubes, dvds, major porn performers and more!  But do you think these things just happen?  Heck to the NO!

I spent my New Year’s Eve weekend testing new products with a most wonderfully open-minded group of like individuals.  (Some of whom you have seen in films…)  There were women, men, trans, midgets, all colors, shapes and sizes, you name it, they were there.  We started Friday afternoon and continued on to Sunday Lunchtime.  And let me tell you, there was no toy, lube, position, combination or video left undone.  Nothing was left unprobed.  Some products passed with flying colors.  Some went to the recycle bin.  Most were used up and worn out.  Just like us.

The lubes had to reduce the friction co-efficient adequately to facilitate multiple rounds of penetration of varying depths and rates of acceleration.  Which means they had to be slippery as all get out, fast or slow and last long enough for everyone to be happy.  There were all types of products to lube, eat and drink for every occasion.  (Most of which are still Top Secret so I can’t tell you much yet!)

The Good Old Doc himself went into sensory overload more than once.  And I am pretty experienced so that should tell you something.  It was probably Monday afternoon before the buzzing in my ears stopped.  Oh the toys!  The colors, the colors!  Oh the humanity!  Thank goodness they finally untied me.

But we did it.  For you.  Because we care.  Your pleasure is our business and we aim to please.

So next time you think we have some of the best jobs in the world, think again.

We do…
