    Sorry for your situation.  If I hear of something in France, I’ll let you know.

    There oughta’ be a law! Oh wait, there already IS one. “


    This is what I always tell people who think there should be more strict cosmetic regulations.  The regulations clearly state that it is illegal to sell unsafe cosmetics.  What kind of regulations could you possibly have that are more strict than requiring companies only sell safe cosmetics?

    The producer may also have substandard disinfecting procedures for their production equipment.  Or they have developed a biofilm that they haven’t been able to destroy.

    Well, that really depends on what type of ingredients you are including in the clay mask.

    Phenoxyethanol can work as a preservative or parabens.

    My best guess on the third question…the formulator is using an emulsifier that they just don’t list.  The ingredient list you have given does not follow FDA labeling guidelines.  If the formulator is willing to ignore labeling rules it’s really not unreasonable to think that they just don’t list ingredients like emulsifiers, preservatives, and adjustment ingredients that would make the product look less “natural”.

    In the US, the FDA strictly regulates colorants in cosmetics.  That’s why only synthetic iron oxides are allowed.  It’s an FDA requirement.  I’m not sure if there is any real risk to using natural ones except they might be contaminated with higher levels of heavy metals.  Synthetic colorants are actually more pure than natural ones.

    Yeah if it works, it’s certainly a drug.  Although they talk about the nebulous “self-protection function” whatever that means.

    It really doesn’t seem like the Alcohol is needed in this formula (or the anionic surfactants for that matter).  I wonder what the formula feels like.

    Well, the type of oils you use matters for calculating the HLB.

    Also, can you tell us what you consider a Natural emulsifier?  There isn’t a legal definition for it so you can pretty much call any emulsifier “natural” if you want.

    You might check with @The_Microbiologist

    His company is Cosmetic Test Labs and does the kind of testing that you are talking about.

    March 12, 2014 at 6:58 pm in reply to: Barrier forming agents (Hydrolyzed proteins, dimethicone ++) - Do they work?

    I looked for some published research on those but couldn’t find anything.  Here is a relevant one on various oils and TEWL though.  http://journal.scconline.org//pdf/cc1979/cc030n06/p00345-p00356.pdf 

    I doubt that vegetable oils would be occlusive enough to provide much benefit.  Shea butter may be better as it has longer chain fatty acids but not as good as petrolatum.

    @bobzchemist - Well, I think people are always looking for shortcuts and asking questions like these are the best way they know how.  

    But I agree, if the company cannot spend money to ensure that their products are safe they absolutely shouldn’t be selling them or in that business.  I mean really, how much money are we talking about, a few hundred dollars?  That should all be rolled into the cost of doing business.

    No.  Aloe juice / aloe gel will not be more efficient at retaining curls.  But like @bobzchemist said the only way for you to know is to test it yourself.

    As a biology major I have no problem seeing Bees as animals.

    But I agree, animal products like Lanolin, honey and Beeswax should not be a problem in cosmetics.  No animals are harmed in getting them.

    Typically, carbomer formulas are adjusted at the end of the procedure.

    It is difficult to give you advice without knowing your complete formula.

    Right.  Barrier ingredients are occlusive agents.  Some work better than others.  Petrolatum is one of the best.  Dimethicone is pretty good too.  That’s why these ingredients are used.

    “It depends” is frequently the answer in matters of science.

    Of course any specific case is anecdotal evidence but here is my recent experience.

    I had an MRI in the US two years ago.  It cost me $4500 out of pocket. Total cost was a lot more but insurance covered it.  Insurance costs me ~$3600 a year.

    4-5% salt for thickening!  Wow!!  You might try to cut that back to under 2%.  Also, you didn’t say whether that was 100% active SLES or 25% active SLES.  If it is the latter, your 4% SLES is really 1% SLES.

    8% SLES, 2% CAPB should be a good foaming starting point.
