    Interesting.  The formulas I used to work with had a 3:1 primary detergent:CAPB ratio.  50:50 seems pretty high.

    I concur.  1% panthenol isn’t going to have any positive effect.  You can reduce it to 0.1%   Cut the castor oil down to under 1%.

    Linalool is an ingredient in the fragrance.  It has to be listed because it is a known allergen and the EU requires listing of 26 known allergens if they are in your product.

    Indeed, marketing does have a lot of sway in the way things are done in the cosmetic industry.

    @nasrins - We’ll keep adding to the list of acronyms as they come up.

    This discussion and a few articles I recently read prompted me to write the following post about preservatives.  What do you think?

    In truth I don’t really know. I had the luxury of a packaging department who handled these questions.  We gave them the product specifications and they brought us a working solution.  

    I would suggest you talk to the packaging supplier.  Tell them what you need and they should be able to provide a working solution.

    Here’s an ingredient list which is pretty standard.  

    Butane, Isobutane, Oryza Sativa (Rice) Starch, Propane, Alcohol Denat, Parfume, Limonene, Linanool, Geranol, Benzyl Benzoate, Distearyldimonium, Cetrimonium Chloride
      
    Butane, propane and isobutane are the propellant. Starch is the functional ingredient.

    Indeed I had one and still do.  Here it is…

    However, I like @bobzchemist idea of creating a more extensive one for this forum and pinning it at the top.

    Yes, there is no need for insults.

    We do have people of varying levels of expertise & in different parts of the world on the forum.  Not all abbreviations are universal in the industry so it is helpful to occasionally explain acronyms.  However, no one is under any requirement to do so & should not be insulted for not doing it.
    LLP = Light liquid paraffin
    SE = Self-emulsifying
    LO = Lauramine Oxide
    Thanks everyone for their contributions and please keep things civil.

    Well, you don’t have a thickening agent so you might start by adding one.  Hydroxyethylcellulose might be a good choice.

    Ultimately this number depends on how much money you want to make and how much money your distributor would be willing to pay.  I don’t know, it depends on the product.

    If it cost you $100 to make a batch, I would sell it for $300 - $400 or more.

    These are all just marketing terms so it would be difficult to describe differences without some specific product examples.  For instance CC cream might mean color control cream according to one marketer while it might mean color correcting cream to another.  They’re both right.

    It sounds like you’re essentially setting up an affiliate program.  So, maybe a 10 to 15% would be generous.  Amazon pays about 5% or less.

    October 27, 2014 at 3:21 pm in reply to: Honey

    @herakilt - Technically, cosmetics are not supposed to have any permanent effect on skin or hair beyond changing the appearance.  So things like wound healing or wrinkle removing or collagen stimulating or claims like that are either…exaggerations or the product is a mislabled drug.  In the vast majority of cases it is an exaggeration.

    When you see a body wash with things like Aloe or Honey or proteins or vitamins or some other extract it is highly unlikely those additives matter from a functional standpoint.  It is doubtful you could tell any difference on a blinded basis between a formula that contains those ingredients and a similar product that doesn’t contain the ingredients.  
    However, it is true that consumers like those type of ingredients to be included in their products.  Consumer like to have vitamins in their hair products even though the science demonstrates that they don’t do anything.
    It is a routine thing for formulators to put ingredients in their products that aren’t expected to have any functional benefit.  We call them “claims ingredients”.  You might find this article interesting.  https://chemistscorner.com/7-types-of-cosmetic-story-ingredients/
    I don’t really have a problem with this type of marketing for cosmetics.  To me people do not use cosmetics just for the function they provide.  Cosmetics are aspirational and they affect the way people feel.  It is up to we formulators to enhance the product however we can to make it more appealing to consumers.  If this means that we add ingredients to help support a product story, then that is what we do.
    So, go ahead and add honey to your shampoo.  If it is more appealing to your consumer that you use raw honey or honey from some special insect out of the Brazilian rainforest, then by all means add it.  Just don’t fall for your own marketing stories.  There is zero evidence that adding honey to your formula will have any functional benefit.

    Hello @heraklit - thanks for your comments and links.  Wound healing is not really a cosmetic effect but I was unaware that it’s use as such had been investigated. 

    I can only speak to the use of honey in shampoo formulas, and in the work that I was involved with (we investigated honey as an ingredient) we couldn’t demonstrate any effect at a variety of levels.

    The cosmetic qualities of honey are not obvious as I can’t think of any beyond it being a humectant.  And there are better humectants than honey.  In truth, I’ve never found any humectants to have much effect in a shampoo.

    I’ve done the experiment where I’ve made shampoos with and without humectants and couldn’t find any difference in the way it affected the feel of hair.  So, at least based on my experience, it wouldn’t matter whether you used raw honey, honey extract or no honey at all.

    What function do you expect the honey to perform in the shampoo?  It seems like it would just get rinsed away during use.

    Since a company can use the term organic however they want I think you could make a 100% organic lotion. Not USDA certified organic of course.

    October 22, 2014 at 6:33 pm in reply to: Ammonium Alum (aka Ammonium aluminum)

    I suppose it’s because Ammonium Aluminum is not listed in the monograph as an approved active ingredient for antiperspirants.  This is also the reason they aren’t required to list their use %

    FDA monograph here.

    Well not exactly banned. You can still get a prescription for it from a doctor.
