Selling Ingredients for DIY Mixing

Yes, it is generally possible to sell ingredients like Double Hyaluron Liquid in bottles for users to mix into their own cosmetic bases such as creams or shampoos, similar to popular products from Japan. This approach can be compliant with FDA regulations.

Key Considerations for FDA Compliance:

• Follow Usage Guidelines: Ensure that the ingredients are used by the end-user according to the recommended usage rates and methods provided by the supplier. For example, the usage rate for Double Hyaluron Liquid is 1-20%, depending on skin type.
• Product Information: Provide clear instructions and information to the end-user regarding the proper way to mix and use the ingredient, including recommended concentrations and any safety precautions.
• Ingredient Registration: The ingredients themselves, when sold individually, should comply with cosmetic ingredient regulations. When the end-user creates a final product by mixing, that final product would technically be a new cosmetic product, and its safety and labeling would fall under the user's responsibility if they were to sell it. However, for personal use, following the supplier's guidelines is key.

In summary, selling ingredients like Double Hyaluron Liquid for DIY mixing is feasible and can align with FDA requirements as long as the usage is within the recommended guidelines provided for the specific ingredient.
