    Chemists are weak in Maths for the same reason they are weak in Englishs

    no, a mathematician can learn a language in 6 months

    Do you know how many years a literary  needs to learn mathematics

    Sorry, those weren’t meant to be serious replies. Just humorous puns.

    There is no good serious reply to your question because I don’t believe it is generally true that chemists are weak at math. In fact, to become a chemist you have to complete a year of Calculus. You have to take Physical Chemistry which is applied calculus. And you have to take Statistics. 

    But formulators do not have to use much math beyond calculating percentages of ingredients and working out the statistics of a market research study. So that could be a reason that you don’t see a lot of brilliant math coming from cosmetic chemists.

    heelo dear happy to meet you  in think tht i have to  take more and more from

    Different Chemists uses math to different degrees. If you were to find a physical chemist, a quantum chemist, an analytical chemist or computational chemist, you would find some chemists who know a great deal of math.
    And while these subjects focus on the mathematics behind chemistry, all chemists need to know some level of these subjects.
    Basically, calling chemists bad at math is wrong and overgeneralizing.
    Granted most synthesis chemists use less specific math on an everyday basis, but they need to have a grasp of the underlying math in order to do their job properly.
    Formulating chemists have to use even less math, but need a better grasp on the interaction of various ingredients innately - every subject requires different levels. And if you dig deeper into cosmetic chemistry than most cosmetic chemists need to, there is actual math to find as the systems are thermodynamic by nature. Stokes Equation, Derjjaguin-Landau-Verwey-Overbeek theory, The Hagen-Poiseulle equation. These and many more are used by cosmetic chemists on a practical and empirical level.

    very haapy to meet you dear
    i inderstnd you very thanks

    iam abderezak from algeria I came from mathematics to thechemistry
    I am so excited to become a part of this forum!
    I am a new formulator
    I look forward to learning, sharing, discussing with you all!

    There could be any number of reasons.

    Maybe because it’s too basic

    or maybe because we only use math periodically.

    or maybe because our calculators Argon

    you too know that chemists are are weak in mathematics  ?

    January 26, 2019 at 1:13 pm in reply to: Is it possible to mix a silicone base with HA ?

    Hello,

    I am new to this site and my chemistry knowledge is pretty dusted but I would  like to start making my own cosmetic products for personal use and will appreciate any advice you kind people can give :-).
    I am trying to make a very light facial moisturizer and have ordered ingredients from Lotioncrafter. I am planning to make a hyalorunic acid gel as follows:

    Percent         Grams            Ingredient

     

      85                85                 Apple Essence

      1                  1                  Hyaluronic Acid HMW - 1.0 - 1.5 Million Daltons

      1                  1                  Hyaluronic Acid ELMW 80,000 - 110,000 Daltons

      5                  5                  dl-Panthenol

      5                  5                  Apple Stem Cell Extract 

      3                  3                  Leucidal Liquid

    I have done this one previously and it worked well.

    This time I would like to possible mix this HA gel with the 
    LC995 Cyclomethicone( 96% Cyclopentasiloxane (D5)) somehow  and then add some of Lotioncrafter EL40 ( Dimethicone (and) Dimethicone Crosspolymer) for thickening.
    Is it at all possible ? Do I need to add anything if I want the HA gel and the silicone base to come together ? 
    I believe the silicone base is anhydrous so I can not add the HA to it just so ( as powder) right ? :-) 🙂

    I apologize if I am talking rubbish - any advice is appreciated.

    Thank you

    Helena
