Ingredient Listing for Cosmetic Blends (e.g., Matrixyl 3000)
Question
How should I list the ingredients for a blend like Pal-GHK, Pal-GQPR (eq Matrixyl 3000) on a cosmetic product label? Specifically, how do I determine the correct order for the ingredient list, which includes components listed in the INCI name: Glycerin, Water, Butylene Glycol, Carbomer, Polysorbate 20, Palmitoyl Oligopeptide, and Palmitoyl Tetrapeptide-7? What information is needed from the supplier for accurate listing and regulatory compliance (e.g., FDA/อย. registration)?
Answer
Ingredient Listing for Blends like Matrixyl 3000
When listing ingredients for a cosmetic product, the standard practice is to list them in descending order of concentration in the final formulation.
For a blend like Pal-GHK, Pal-GQPR (eq Matrixyl 3000), which is a mixture of different components, the INCI name lists these components. The INCI name for this product is:
- Glycerin
- Water
- Butylene Glycol
- Carbomer
- Polysorbate 20
- Palmitoyl Oligopeptide
- Palmitoyl Tetrapeptide-7
To correctly list these components in your product's ingredient list, you need to know the concentration of each individual component as it exists in your final formula. This requires knowing the exact breakdown composition of the Pal-GHK, Pal-GQPR (eq Matrixyl 3000) blend itself.
As the staff correctly advised, the most accurate way to obtain this detailed breakdown for regulatory purposes (such as FDA/อย. registration) is to request the Certificate of Analysis or technical documentation from the supplier (MySkinRecipes). This document will provide the necessary percentages of each component within the blend, allowing you to calculate their final concentration in your product and list them in the correct descending order.
