    We used to live by the rule that 8 weeks at 45C was predictive to a year of RT stability.

    @mariacosmo - could you provide an ingredient list so we know exactly what product you are talking about?

    It sounds like over charging to me but I don’t create foundations so I’ll let others weigh in.

    It would help if you list all the ingredients you are using.

    While I suspect that asking for a preservative free product is because of an erroneous belief that preservatives will harm people, but I don’t know that for a fact.

    That’s why I asked why someone would want a preservative free product. I want to understand what specifically is the objection.

    The society of cosmetic chemists.  http://midwestscc.org

    In fact, there is a free trade show coming up in April called Teamworks. Every company that is any company in the cosmetic industry in Chicago will be there.

    Interesting.  That doesn’t seem like it will be good for EOS sales.

    A combination would probably lead to a system with better stability.  But it really depends on the system and is only something that can be determined through testing.

    Tea Tree oil is a chemical.  In fact, all oils are chemicals.  It is impossible to have a chemical free preservative.

    Help me understand, why would you want to make a skincare product with no preservative?

    We used either a TEWL meter or a Corneometer.

    Technically, any reading outside your initial specifications is an unstable product.  Color changes, odor changes, and separations are all subjective measures of stability failure.

    We had a product that claimed “24 hour moisturization.”  To prove it we did a study where we measured skin prior to product use, then immediately after to show moisturization.  We had the people come back the next day and measured their skin and showed that there was still some moisturizing effect beyond what their skin was prior to the study.  There was also a control group who got no treatment.

    The study couldn’t be called scientifically rigorous and it’s unlikely that any consumer would notice the difference but the claim was valid and passed the standards of television (which is the toughest advertising standards to pass).
    As far as the ingredients go, yes, you need a film former and a good slug of Petrolatum to get the skin moisturized. Carbomer doesn’t do much in terms of moisturization.

    The advice you’ve been given so far is right on.

    But if making products and selling them is what you are after you would be better off going to a contract manufacturer and working with them to develop the formula. If you want to be a chemist by all means take a course like ours (https://chemistscorner.com/members). But if you want to have your own cosmetic line, get someone else to make your products.
    Also, you might find our free report on the subject helpful.  http://startacosmeticline.com

    I would guess that those types of products would be seized by customs agents prior to be allowed into the country.  But I don’t really know.

    As to the link you posted, it’s interesting but it demonstrates the problem

    “Black women, in particular, spend an estimated $7.5 billion annually on beauty products,”
    This sounds like a big number, but if you look at the overall market size, the market is estimated to be >$83 billion.  http://www.statista.com/statistics/254608/global-hair-care-market-size/
    This represents less than 10% of the market, so the way business people think we should expect they would dedicate 10% of their resources to developing these kinds of products.
    I’m not saying this is right or wrong, it’s just an explanation about why there are so few experts in this particular market segment.  The good news is that it represents a market opportunity for a motivated entrepreneur.

    Well, just make sure you don’t use the claim “skin lightening” or any of the other claims that are considered drug claims by the FDA.

    Not to mention that Coconut oil is rather comedogenic.

    Hello

    You’re frustrations are understandable. I can only give you my experience.  I worked at Alberto Culver and during my time our company produced the TCB line and the Motions line. In the 17 years that I worked there I was never assigned a project to work on these particular product lines. We had 4 chemists who worked on those projects and really, there was 1 chemist (who was excellent) who did more than half the projects.  In the entire company we had probably 70 formulating chemists.  So you can see only 4/70 were focused on ethnic hair care.
    The answer to your question is that the reason you don’t get answers in this area is because the vast majority of formulating chemists do not focus on ethnic hair care.  This is because it is a sub-segment of the overall hair care market.  I’m guessing but the sales of ethnic hair care products probably represents about 20% of the entire hair care market.  Companies who do not have brands specializing in these markets do not dedicate any resources to them and even companies that do have a presence in the market (like my former company) they dedicate very few resources to the brands.
    Having said that, there certainly are experts in the ethnic hair care area, it’s just that it is a specialty and those experts don’t seem to participate on Internet forums as much.
