    I absolutely agree that as a cosmetic chemist should be familiar with all the product
    formulation being mostly used. But I also agree that we need to be specialized in
    just 2-3 types of the product as it is almost impossible to cover it all. Can’t wait to
    see the next session about testing the cosmetic products. Thanks.

    hi Perry, many thanks for your excellent programs. May I please ask how do you obtain clear suspension for natural products. I am aware carbomers, polymers are great but they are synthetic. Are you aware of any natural alternative? kind rgds Arek

      You can try clays (although you may likely get a slightly hazy formula). If you consider Cellulosics natural you could try HEC or HPMC

    Hi Perry. Thanks again for giving novices like me a great insight into the cosmetic industry. I wqs quite disppointed as the video stops playing approx 2/3 of the way through so I did get to hear any pointers you might have mentioned which is not in the download slides. Can you fix it? Thanx in advance.

    Dear Perry, thank you very much for your presentations.
    I never used any special cosmetic products for my skin. They say that I am looking 10 years younger and I find it is very nice compliment.
    Anyway last time the subject about cosmetic products excites me and I read, learn more and more about creams, soaps, shampoos…
    I have the Master degree of anorganic chemistry and was 20 years chemistry teacher at secondary school. Strange that only now I start feel something very special for homemade cosmetic products.
    Now it is my very hot hobby, I feel almost addicted on the process of creating a new natural soaps and creams. I believe you will give some advices for homemade natural cosmetic.

    Hi Perry, Thank you for the video. I was hoping some formulation would be shared for each product type with some explanation. I am a chemist in career transition. I would like to transition into cosmetics chemistry. You explanations have overall been very helpful. Thank you.

    Always informative. The course provides great insight and provokes new questions each time I review.
    I was wondering if there is a ‘rule of thumb’ when or what part of the year formulators begin developing new application specific products such as sun care, color cosmetics , moisturizers etc .I was once told that such a ‘schedule’ exists and that certain product formulations are season specific as far as when the development begins.

    Great! The little chemist I always had inside me is waking!
    I am just a little bit cautious about using some ingredients, because not all ingredients used by cosmetics industry are skin or enviromental friendly.
    I would really appreciate if you provided us with a lesson concerning that issue!

      Perry Romanowski says:

      The ingredients used in the cosmetic industry are tested for safety and effectiveness (it is illegal to sell unsafe cosmetics in the US).

    This was highly informative for someone like me who is planning to make a living by making creams etc in Pakistan.
    I did my high school with science . I have had a great passion for making cosmetics but never knew where to start from.
    Your lectures have given me a lot of hope regarding my passion.
    I want to learn a lot more from you Sir and I hope you will help me out in this matter,

    I can only think of one improvement to this segment: have a photograph of each of the product types. For example, in the OINTMENTS, have a photo of a 1st aid ointment, and one of toothpaste.
    Well-written and well-performed!

It is informative, and presented in a way which is interesting, shows the science behind the methods and products, but also is easy to understand for those of us who don’t have chemistry degrees.

      Actual formulas are presented but only as demonstrations. This isn’t a course in which you follow step-by-step to make a formula.
