  • Formulation Percentage In Existing Product Query

    Posted by Beaufused on October 2, 2020 at 1:53 pm

    Hi all,

    I have been working with various contract manufacturers for a little while now to create my first product for my cosmetic brand. I have had numerous samples back and we just don’t seem to be creating something that I am entirely happy with.

    There is an existing brand that has a product which is similar to what I would like to create for my own brand, however there are a few ingredients that I would take out and potentially substitute with ‘natural’ alternatives if possible. 

    I just wanted to know if it possible to find out the exact percentage of each ingredient in this product, maybe there is a key ingredient I am missing which potentially might help me create a formula I am finally happy with. 

    This is the ingredients list of the existing product (in order it appears on the packaging):
    Acrylates, Ethylhexyl Acrylate Copolymer, Aqua, Hydrogenated Castor Oil, Matricaria Recutita Chamomile Flower Extract

    Just to note we are using Pullulan instead of Acrylates as a natural adhesive, however the product still doesn’t seem to have a strong enough hold like the one above.

    Any kind of advice/help would be greatly appreciated, as I have no formulation knowledge whatsoever.

    No, unless you know the formula, you can’t really get the exact percentages.
    You could weigh a sample, put it in an oven for a few hours, then weigh it again. That will give you the approximate percentage of water.
    You’ll have to guess at the rest.

    The product doesn’t have a strong hold because you’re taking out a good technology and replacing it with some that is inferior. If you want stronger hold, use the Acrylates.  For the most part, natural ingredients do not work as well as synthetic ones.  If they did, that would be the technology that people use.

    Synthetic ingredients are made specifically to perform better than whatever natural material it is replacing. 

    We don’t ride horses (natural) because cars (synthetic) work better.

    Natural = performs worse

    @Perry Thank you for your advice.

    I think the best route for me is to definitely look into adding acrylates in the formula.

    If you had tried True Glue the All Natural one vs their colored series.
    you may noticed the difference hold they gave.

    @Pattsi Yes I did order all three glues. The all natural and their white and black lash adhesive have a completely different (stronger) hold, which I do feel is to do with the Acrylates. 

    I have gone back to my cosmetic manufacturer with the above feedback, so hopefully I can implement this in my own formula.

    Thanks for responding.
