    Thanks Perry!

    Perry, what would be a good source to find scientific information for supporting a claim test?

    Could a search for benefits on an ingredient on the Internet do the trick? The thing is with so many misinformed people we find crazy information on the internet from people who don’t have the knowledge.

    How would a cosmetic formulater or homecrafter research and support a claim with some knowledge but with no science education degree? For one hiring a cosmetic chemist would be a choice, but if someone did not have the capital to do so what would an option be?

    1. Perry Romanowski

      That’s a good question. You can find some descriptions of tests in places like the Journal of the Society of Cosmetic Chemists. You can also ask raw material suppliers what tests they use.

      To support a claim searching the Internet is not likely to help. Often you have to imagine a test that would demonstrate your claim then run the test. I’ve found test methods in patents also.

    I have seen one advertise and its mentioned that our hair oil content 300 % more vitamin E.

    What does it mean i don’t know

      It’s not clear from the way you have written it. That could simply mean it has 300% more vitamin E than skin sebum or some product. When analyzing claims it’s important to write down exactly the words that they use.

    You mention in the audio that we need to use a “control”. Supposing you take 100 people with psoriasis. You give your cream to these people and in less than 30 days, 87 of those 100 people have noticeable reductions in the inflammation, itching and other symptoms. So without a control, one could say “87% of people trying our cream show noticeable improvement in symptoms within 30 days”. So to add a control, you take what? a competitors cream? or a placebo? What would you use as a placebo cream? Any thoughts on this?

    1. Perry Romanowski

      Without a control you could say that, but your test doesn’t prove your cream works and you wouldn’t be able to make that claim in advertising. To do a proper test you need to have two groups of 100 (or two groups of 50 people). To one group you give them your cream. To another group you give them a placebo cream or some standard treatment for psoriasis. If your cream showed a statistically significant number of people who had an improvement then that would help support a claim that your product worked as a treatment.

    A question about anti-age claims. I think I could come up with some way to demonstrate a reduction of wrinkles but how can someone demonstrate to prevent signs of aging?

    Claims can be supported by ensuring that the ingredients in the panel do what the product claims to do.
