Hi Robert.
My position on this is simple. The facts are that cosmetics can use any ingredient provided there is a reason for the ingredient (other than the API use) and the ingredient and formulation are considered to be safe for that intended use, at the intended levels in the product, and for the product category itself.
While I fully agree that there have been several instances in the past that have landed companies in some hot water with FDA, the fact is that many of the allowed active ingredients listed in OTC monographs have also been used in cosmetic products for decades for other purposes. Let's take a few examples below that I can speak to directly (just so that we aren't speaking in over-generalized terms and I apologize if any of this sounds like it is too elementary - just trying to level set here):
1. Glycerin. This is an ingredient that has been used in cosmetic products at levels over 50% for decades. The purpose of the ingredient generally in cosmetics is as a humectant and a moisturizer. FDA has never, to my knowledge, considered the inclusion of glycerin in a cosmetic product as indicative of the product's true purpose being that of a drug absent other indications of that purpose (claims made on the product leaching into the OTC world, etc.). That said, glycerin is an allowed OTC API in several different OTC monographs including oral demulcents and even skin protectants. I think this is a strong case that just including an ingredient that is allowed as an OTC API doesn't necessarily mean that the FDA will have issues.
2. Salicylic Acid. This is an ingredient again that has been used in cosmetics for a long time. The ingredient can be used for adjusting pH or even as an effective exfoliating ingredient. It is also allowed in the OTC world as an anti-acne, anti-dandruff, anti-psoriasis API at levels as low as 0.5%. Again, absent other indications that the ingredient is intended to produce or elicit a drug effect on the body, I am not aware of FDA having taken any action on this ingredient ever.
3. Titanium Dioxide. This has been used in cosmetics products since the origination of color cosmetics from what I can tell. The purpose of this in a cosmetic is to allow the color pallet to be "dialed" to provide different shades of the same "base color" across different specific formulations. It can also be used as a bulking agent to allow for more consistent production of pressed powders. In addition to this Titanium Dioxide is used as an API in the sunscreen monograph "up to 25%" which implies that any level up to and including 25% could be considered a drug API. However, once again, I am not aware of FDA challenging products with titanium dioxide as unapproved (or even unlisted) drug products absent some other indication in the labeling that the product is intended as a drug.
4. Dimethicone. The ingredient is often used in cosmetics as a slip modifier, a hair or skin conditioning agent or a film forming agent with the purpose of ensuring that the product helps prevent moisture loss from the skin. Again, this is also a skin protectant API but absent some other indication of drug purpose, the simple inclusion of this ingredient in the formulation ingredient list has never, to my knowledge, caused FDA to challenge a product as a drug.
These are just 4 specific examples I can think of off the top of my head that would substantiate that just because something is listed in the OTC API listings it doesn't necessarily mean that the resulting product is a "drug" in the definitions in both 21 USC and 21 CFR. This said, as I noted earlier on in the discussion, the use of an API that is a prescription API would likely cause a significant discussion between the company and the FDA. So addition of something like tadalifil in a cosmetic is going to get FDA's attention pretty quickly. But the cases of that in my opinion are extremely rare and few and far between. Most of the other issues I suspect you have seen specifically include issues around the use of the API from a monograph and then someone trying to get a little too cute for FDA's liking in the way they market the product. This invariably seems to cause FDA to see the product as being a drug product which ultimately is found to be mislabeled because it is missing the drug facts labeling that is required for OTC monograph items and even might be outside the scope of the monograph (either the API level could be too high or even too low to make the claims).
Also, keep in mind that 21 CFR 701 et seq does contain a specific listing of ingredients that cannot form part of a cosmetic product ever. You will notice if you look at this listing that I believe it only contains something like a dozen or so items and none of them are actually APIs nor is there a specific mention of APIs in this listing at this point. While FDA could always find with sufficient evidence that the product is an unapproved new drug for any of the GMP reasons they still need to show that somehow there is a connection between the product and some representation in the labeling that the product is meant to be a drug. Otherwise, I would guess 99% of all cosmetic products on the market today would require drug facts labeling because almost every product I have ever been involved in working on in the past 25+ years in the cosmetics area has had at least 1 OTC API in the ingredient listing and most every one has had the OTC API at the levels allowed under the monograph rules to act as a drug. The reason that they haven't been called out as drugs was the fact that the claims made on labeling did not rise to the level of drug claims.
Sorry for the seeming dissertation on this one. I did not intend for this to get nearly this long. But I thought it would be somewhat helpful. I apologize if I have mistakenly categorized this as helpful....

Hi All,
A discussion is useful when we are supported by facts. I appreciate Rob Falcone's suggestion. I would recommend before a discussion or as part of one, a list of regulatory and/or legal documents that discuss placement of APIs and/or drugs in cosmetics without claims. For example if no claims are the drugs listed first on the panels or buried in the cosmetic ingredient list. Then how does one support the presence of the API or drug without a claim. Note that the API or drug in the cosmetic is at the level approved for use in the quantity as a drug. In our practice we are asked this question quite frequently. We are also very familiar with Warning Letters concerning this situation.
We would appreciate any list of documents or citations in the USC , CFR, guidances, etc. which discuss this situation; especially where possible AEs and warnings are involved. Information outside the US will be very helpful.

Will everyone be interested in participating in a meeting discussing all aspects of OTC products

There are two issues. The first are the claims which have been well discussed. The second is if there is a drug API in the cosmetic formulation and no drug claim is made then how does the manufacturer account for the purpose of the API if asked? This is as very sticky situation. As Rob and I recently participated in a public forum where it was discussed, there are diverse opinions.
