    Wow, that’s a lot of amide and betaine in the formula!

    More typical would be…
    ALS = 15% (on an actives basis)
    Cocamidopropyl betaine = 5% (on an actives basis)
    Most companies avoid DEA containing ingredients because they have to be listed as carcinogens on California’s Prop 65 list.  In this formula you wouldn’t really need it.

    What do you want the Glutathione to do in your formula?

    If it is just a marketing ingredient choose the one that is the least expensive.

    7.5 pH?  That seems pretty high.

    I think if you could list your entire formula and % you might get better suggestions.

    It sounds like an idea that could work.  

    The hardest part about growing a cosmetic business is getting good marketing.  In fact some brands (like Paul Mitchell) launched without any R&D group.

    Add less oil.  Also, consider using some solubilizer nonionic surfactant like Polysorbate.

    What benefit are you trying to provide by including the oils?  
    You are running into a simple fact of surfactants, they are really good at removing oils.  So trying to put oils in the formula or even getting it to deliver to the surface is extremely difficult.  
    If it is just for marketing reasons, cut the level down to 0.1%.  That should stop the negative viscosity effect.

    Agree with @MakingSkincare

    Ideally, you would be able to test your product at elevated temperatures in the final packaging.

    Your question is a little too vague to give a good answer.  It really depends on what is in the formula.

    I agree with @DavidW - It is going to come down to the opinion of the specific agent who is investigating the claim.  Unfortunately, there are no set answers.

    @perspicacious - I don’t see posting the accused’s username as appropriate given the limited information about the situation.  

    Also, this post isn’t so much directed at a single person or situation, but is more helpful to the community and people who might face a similar problem in the future.  The original poster was looking for advice on what to do, not looking to punish someone who they think treated them poorly.

    Whenever I see an article claiming some simple ingredient is getting amazing results I always keep in mind the three things that can happen whenever you apply an ingredient to a skin condition.

    1.  It gets better
    2.  It gets worse
    3.  There is no change
    This is exactly what can happen if you do nothing to a skin condition.
    Proof of effectiveness requires more than just random people, unblindedly trying things and unskeptically reporting results.  
    There is a reason the FDA requires double-blind, placebo controlled evidence before approving something to treat a disease.
    Maybe the oat meal helped this person.  Or maybe her skin would have cleared up on its own whether she applied to oatmeal treatment or not.  Only a controlled study can answer that question.

    Thanks for the thorough and well-thought out response Bob.

    I agree with you that the best suggestion is to make sure everyone knows what is going to be delivered upfront so there are no surprises.  There should always be some way “out” of the deal too.  
    I tend to think that in most cases the chemist/consultant has the responsibility to make sure their customer is happy (if they can).  Putting yourself in a situation of being called a fraud and leaving a trail of unsatisfied customers in your past is a terrible way to build a business.

    @Bobzchemist - I’ll endeavor to moderate things so it doesn’t devolve into something unhelpful but I think this is a very important question / discussion topic.

    Many people who are on this forum or visit our website are looking for consultants with which to work.  I’m happy to make connections between chemists and people looking for their help but it’s highly troubling to hear that someone might be taking advantage of people.
    I have been contacted by a number of consultants who say they are available for work, but I have no way of knowing whether they are reputable or not.  I just assume everyone is until I hear otherwise.  Even then I give people the benefit of the doubt.  But I feel terrible if someone I’ve recommended would treat someone the way described in the starting message.
    So what can be learned from this?
    1. Buyer beware.
    2. Don’t pay all the money until you get the job done.
    It would be interesting to hear from someone on the other side.  
    What would be the rationale for a contracted chemist to avoid responding to a client?

    I think it comes down to what your lawyers are comfortable with.  There is no set rule so you can only go on what the FDA has flagged other companies for doing wrong.  It’s definitely a gray area.

    Yes, your ingredient lists are pretty much right the way they are now.  You are not allowed to put functional descriptions within the ingredient list.

    I’m not really sure what you are trying to accomplish though.  What question are you trying to answer in your study?

    That’s an excellent point.  Traditionally, the FDA hasn’t bothered people when they make moisturizing claims so you’re safe there.  It’s these more specific claims about stimulating collagen or doing something else to some specific biological pathway that they are cracking down on.

    March 25, 2015 at 7:42 pm in reply to: Advice on selling your products

    I’ll give you my perspective based on using the Internet.  If you are just starting out there is no better way to build your brand than by using the Internet.

    1.  Create a website
    2.  Build an email list of potential clients
    3.  Sell products to your clients via email
    4.  Fill orders through the mail.
    The most successful brands are the ones who focus their efforts on marketing their brand, creating their story, finding their audience, and solving problems for those people.  
    Urban Decay started a makeup brand in 1996 using technology that has been around since the 1960’s.  There is nothing special about their technology.  A few years ago they sold their company for >$150 million.  
    Focus on marketing.

    This depends on lots of different factors including the country you are in, the type of product, and the types of claims you’re going to make. 

    See this post we did on the subject.

    In truth, you could probably use even less Panthenol.
