How must ingredients be listed on cosmetic package labels?

Ingredients on cosmetic package labels must be listed in descending order of concentration. This means that the ingredient that is present in the highest amount is listed first, followed by the next most abundant ingredient, and so on, until the ingredient present in the lowest amount is listed last. This labeling requirement helps consumers understand the composition of the product, as it indicates which ingredients are the most significant in terms of quantity. This practice is not only a standard in many countries but also a key component of ensuring transparency and safety in cosmetic products. By following this standardized method of listing, manufacturers allow consumers to make informed choices based on their preferences and needs regarding specific ingredients.
