We all expect the ingredient declaration in cosmetics to be accurate and include all the ingredients in the product. However, in certain circumstances, “incidental ingredients” may be left off the list. It’s a loophole that can sometimes be abused.
When labeling your own products it is very important to know and understand what may or may not be omitted from the ingredient list as an “incidental ingredient.”
When purchasing materials from suppliers, it is VITAL that you are confident that you have a correct ingredient list and that the “incidental ingredients” provision hasn’t been used to hide ingredients that really should have been included. After all, when you use those materials in your products and rely on the supplier’s ingredient declaration, the buck stops with you if something is intentionally omitted from your product’s ingredient declaration.
Occurring or likely to occur by chance in connection with something else more important.
Something that enters or is added into the formulation of a compound or mixture. A component part; a constituent. (From the Latin to enter)
Incidental Ingredient:1Components present at insignificant levels which have no technical or functional effect in the cosmetic, including:
- Substances with no technical or functional effect that were added because they were in an ingredient used in the product;
- Processing aids.
As you can see from the definitions, the key here is that the substance is in the final product because it is minor, came with some other ingredient and doesn’t have any technical or functional effect OR it was something that helped with the processing (and is no longer in the product).
1. Added as part of another ingredient.
Sometimes you purchase a product which has a small amount of a component ingredient that is no longer functional when it’s added to your product. Or the component ingredient doesn’t have any technical effect in your product.
Example: You purchase a flower water that has a small amount of preservative in it, and add the flower water to your product. The amount of preservative that ends up in your product in miniscule and no longer functions as an effective preservative. In that case, the preservative in the flower water is likely an incidental ingredient and does not need to be included in the ingredient declaration for your product.
HOWEVER, if your product consisted of all, or primarily, the flower water, and the preservative in the flower water was being calculated as part of the overall preservative system – then the preservative isn’t incidental and would need to be included in the ingredient declaration.
2. Processing Aids
The regulations describe three different types of processing aids that may be considered incidental ingredients (and therefore omitted from the ingredient declaration).
[NOTE: I use cooking examples below, which are intended only examples in formulating and are used to compare with similar chemistry in cosmetics. Food has different regulations and in these examples the egg whites and/or lemon juice may be required to be included on a food ingredient label.]
a) Added, then removed
A substance that is added during the processing of the cosmetic and then removed from the cosmetic before it is packaged is considered a processing aid and therefore an incidental ingredient. Technically, it’s not in the finished product and therefore doesn’t need to be included in the ingredient declaration.
In cooking, this would be like using an egg whites to clarify cloudy broth. The egg whites are added in, but then strained out before the broth is used.
b) Added, then converted to something already in the product
A substance that is added to the cosmetic during processing for the technical or functional effect in the processing, but is then coverted to something already in the ingredient declaration.
I don’t have an example of this, but you can see that since the substance gets converted to something already in the ingredient declaration it would be incidental.
c) Added for processing, but insignificant amounts and effect in the product
A substance which is added during the processing for its functional or technical effect, but is only present at in the finished product at insignificant levels and doesn’t have any technical or functional effect in the finished product.
This might be the case for using egg whites and lemon juice to clarify stock. When you strain it, there MAY be bits of egg white left, but there is no way to strain out the lemon juice – it stays in the stock pot. But it’s there in such small quanitites and isn’t doing anything to the flavor or format of the resultant stock. In that case, the lemon juice might be considered a processing aid and an incidental ingredient.
What to look for
When you are making soap or cosmetics to sell, it is your responsibility to ensure that the ingredient declaration is correct. That means when you purchase a blended ingredient, you should do your research to make sure that the company you are purchasing from is ethically and accurately disclosing all the ingredients that need to be included in the ingredient declaration.
Recently I saw the following as a footnote on an ingredient declaration list:
Our process aids are used in small amounts, on an as needed basis, and are not essential for product function. They are subject to change as they are constantly evolving and changing due to the availability of newer and better materials, marketplace demands, etc. In order to provide our customers with various desired features such as ease of remelting and re-batching, finished product final appearance, etc. we may or may not use small amounts of the following (or similar) materials…
Obviously, I don’t have all of the fomulation details, but I do find the statement contradictory. First they say the process aids are used in small amounts and are not essential for product function, and then in the very next sentence they say they are necessary to provide customers with various desired features. That sounds like the materials are added for technical or functional effect if they used to meet customer needs in the product.
