    This isn’t an easy problem to solve.  Like Robert says, make an anhydrous formula.

    Hello @MakeupCook and welcome to the forum.  Hope you find these answers enlightening.

    1.  No.  If it were easy to replace petroleum based ingredients with “natural” alternatives that worked just as well, no one would use the petroleum based ingredients.  Synthetic ingredients just work better.  But there are plenty of inferior ingredients you can use.  You just have to describe what you are trying to accomplish.  For example, you can use Beeswax for a lip balm.  It’s not as nice as Petrolatum based balms but you can use it.
    2.  This depends on what type of equipment you are looking to buy and what you mean by “reasonably priced”.  Need to be more specific.
    3.  There are lots of lists which you can find here.  List of natural and organic standards.  But you should realize that the list are arbitrary and simply reflect the opinion of the person making the list.  There is no “official” list of natural / organic ingredients as anyone can use this term about any ingredient if they want.
    4.  No.  There is no official certifying body that would certify manufacturers.  
    Hope that helps.
    Perry, 44

    The PVM/MA Decadience Crosspolymer (Stabileze) would probably be enough to keep it stable.

    While it would be nice if marketing groups tried to educate consumers I don’t think it is really their role.  They are trying to get people to purchase products.  Education needs to be up to the school system, the media and independent sites like this one.  Unfortunately, we do not put enough emphasis in school on teaching critical thinking skills.

    As far as innovation goes, there are two effects this has.  First, it will force cosmetic chemists to be more innovative in the way they create their products.  Just forcing people to find alternatives of things that work perfectly well is a good way to spark innovation.  However, it will be much more difficult to innovate in the cosmetic industry because of bans on animal testing and a lack of adequate safety testing replacements.  Also, the substitute ingredients will have much less safety data behind them than the current preservatives.  
    I think what will happen is that there will be such an increase in the amount of cases of contamination that regulations will start to require specific preservatives.  And big companies who start banning specific ingredients without good scientific rationale will find that the big manufacturers use alternative means of product distribution.

    @Bati - Yes, I think companies are mistaken.  In fact, most companies still use parabens and most consumers have no idea what they are nor do they care.  Lead in lipstick stories haven’t scared people away from buying lipsticks and stories like this one will not scare consumers away from buying cosmetics with standard preservatives in them.

    Marketers react out of laziness and fear.  That is what is sad.  Good marketers don’t let consumers tell them what they want, they tell consumers what they should buy.
    @Sarah - see another thread in this forum for a discussion on alternatives

    I’m always skeptical of meta analyses.  

    This seems like such a simple question to answer.  Do a study with regular soap versus soap containing antibacterial agent.  It is curious that they would need to point to a meta analysis to prove there is a tiny benefit.

    Right.  Proving that they work better than plain soap and water is going to be a tall order.

    Ah, they will have to prove they are more effective than just regular soap and water.  Yeah, I don’t think that is going to happen.

    Interesting.  I wonder what it means.  The products are presumably already safe and effective aren’t they?

    Just remember…anyone can write anything about anything on the Internet.

    Always double-check sources and be skeptical of what you read.  Paula does a good job of attempting to back up her statements but she is not a scientist.  Ultimately, marketers will get things wrong when they are trying to fit scientific findings into their marketing stories.

    It’s a sad day when companies start giving up perfectly fine preservatives because they think consumers want them to.

    Since formulas are such a big part of this discussion board, I’m going to look into a way to do it better.

    Wow, that’s amazing.

    Sadly, I was at a kids science fair (as a judge) and one of the kids did a “lead in lipstick” display.  She demonstrated a similar technique for detecting lead in lipstick.  
    sigh.

    As far as pasting a spreadsheet, unless you know html code the best way would be to take a screen shot and post the picture.

    It seems that if the product did change color throughout the day that would be a major stability problem.  I still vote myth.  However, it is possible I suppose.

    @simona - I agree!  Pizza is excellent too but would make a terrible facial cleanser.

    I vote Cosmetic Myth.  Unless they are including DHA in their foundation.

    You don’t want to skimp on mixers.  Even the good ones break pretty easily.  Having said that, I don’t know anything about the ones from China sold on Ebay.
