      Not usually through raw material suppliers. But there might be places like that will supply some.

    Hi Perry, do you think that Niacinamide actually works when applied topically or is it just a claims ingredient?

      There are studies that demonstrate it does have an effect when delivered topically. P&G has faith (and research) that it does. Although the effects are small.

    will FDA accept these claims if they really don’t work.

      It depends on how the claims are written. It is illegal to lie or to make drug claims. But if you stick with cosmetic claims and implications, it’s ok.

        Thanks Perry are there any guidelines how to write these claims in the acceptable way

          Not really, although we’re going to have a claims webinar next month or the month after to go over the techniques for writing claims. In the meantime just follow the rule, it is illegal to lie and you need to be able to prove everything you claim.

    Hi Perry, do you consider Glutathion as just a claim ingredient? I ask it because I have never seen it advertised on a label.

      Well, theoretically it can lighten skin color. But it hasn’t been proven to do that when applied topically. And if it did do that, it would make it a drug which hasn’t been approved for that purpose. For the most part, I’d say it’s just a claims ingredient.
