Here is our pilot episode of the Chemists Corner podcast.  Please have a listen and let us know what you think.

Chemists Corner podcast is about cosmetic science and is broadcast to help educate, entertain, and inspire current and future cosmetic scientists. Each episode we’ll talk about news in the cosmetic industry, answer some of your questions, and discuss a topic in-depth, usually with an industry expert interview.

In this episode…

1.  News – Two news stories were discussed.

2.  Listener question – How do you quickly evaluate new raw materials?

3.  Interview – Kelly Dobos on becoming a cosmetic chemist

4.  Weekly Challenge.

Imagine Usain Bolt, Kelly and Perry ran a 100 meter race, each keeping a steady rate of speed.  If Usain beat Kelly by 10 meters and Kelly beat Perry by 10 meters, by how many meters did Usain beat Perry?

If you’ve got an answer to the challenge, have a question, or have any topics you’d like us to cover, leave a comment below.

    where is the podcast, i can’t see it ?

    1. Perry Romanowski

      It’s been added so you should be able to listen to it now.

      1. Prash

        Thank you very much. I noticed a few others missing as well, so hope you can add those as well.
        Kind regards

        1. Perry Romanowski

          Thanks! I also reviewed some of them and found the podcasts missing. I’ve added back the ones I noticed. Will continue to do that until they are all restored. Thanks again! I didn’t even know they were missing.

          1. Prash

            Hi Perry, when you get a chance, please can you upload podcasts from 7 to 15, and 18 to 33. Thanks.

          2. Perry Romanowski

            All fixed! Thanks for letting me know.

    Usain will beat Perry by 19m.

    Even though we don’t know their actual velocities, we can describe the scenario in this way:

    For every 10m Usain travels, Kelly loses 1m. For every 10m Kelly travels Perry loses 1m. Therefore, when Usain is at 100m, Kelly will be at 100m * 9/10 = 90m, and Perry will be at 100m * 9/10 * 9/10 = 81m, 19m behind Usain.

      Great analysis!

    Hi Char,
    Sorry I didn’t get back to you sooner! I didn’t receive notification of your message and just saw it. The program at UC also encompasses a traditional classroom approach and it is also the only place you can get cosmetic science PhD in the US. There is also a program at Fairleigh Dickinson focused on cosmetic science in New Jersey. A masters in organic can help if you plan to work for a manufacturer of cosmetic ingredients, but a cosmetic science degree would be much more relevant to a formulator. The online program is definitely a way to accomplish the degree while working on your schedule, otherwise it may be hard to coordinate classes with work. Let me know if there is anything else I can help with.

    p.s – color cosmetics sounds awesome!!! i’m also interested in perfumery….

    Hi Perry & Kelly!!
    OMG…i loved the podcast!! it was so fascinating listenin to you guys talking about formulating. I really really want to become a formulation chemist, so hearing what kelly had to say in her interview towards the end of the podcast was great!!! You guys have totally inspired me even more…if thats possible! =)
    Kelly, where do you think is a good place to get a Masters on Cosmetic chemistry apart from Uni. of Cincinatti? coz they only offer an online course i think…i’m looking for a traditional one. Would an MSc in organic chem be just as good? Can i work in the industry while i get my Masters?
    please please help me out coz i really want a job like yours!!!! 🙂

    Great podcast guys! I love having the opportunity to hear from fellow cosmetic chemists. I read about the alcohol free hand sanitizer recently and was planning to blog about it. New monographs are expensive and hard to come by. I agree with Kelly, the FDA probably should amp up their methods to get things approved in a reasonable time frame. At the same token, there are plenty of products on the market (OTC) that are technically drugs yet lack a published monologue for their use. I doubt the FDA will ever come close to pulling those products from the shelves ie anti nail biting / thumb sucking products. This hand sanitizer product might escape the radar in the same sense.

  7. Perry

    Close Judy, but not quite. It was a bit of a trick question. See this week’s episode for the answer.

  8. Judy

    Thanks for the podcast, Perry and Kelly; it was interesting and a fun way to share your expertise! Hmm.. No more being lazy about putting on sunscreen. I’d like to take up the weekly challenge: Did Usain beat Perry by 20 meters? I’ve never been good in math and I don’t hope this to be correct; thought I’d give it a shot for the fun of it. 🙂


  9. Kelly

    When it comes to topical acne products, in 1995 an FDA comment specifically stated that benzoyl peroxide should remain available to consumers in OTC products, noting that one manufacturer was in the process of developing additional safety data. It was also noted that this step may take years. But here we are 15 years later and the ingredient is still in Cat III. I’m beginning to think the FDA needs to revamp their approach to provide clarity to consumers and product developers alike while continuing to allow for innovation in active ingredients.

    That makes sense to me SoapyGuy.

    Great podcast, guys! Re: hand sanitizer, I don’t have much experience with the hand sanitizer rules (though I’ve had some experience on the HI&I disinfecting side), but this sounds similar to what happens with benzoyl peroxide products and the acne monograph. BPO is also category III and is used (as far as I know) with no additional requirement for safety info on the end product. Do you guys think this is a valid analogy?
