Cosmetic Registration: Declaring Ingredient Mixtures
Question
When registering cosmetics in Thailand using INCI names, if an ingredient is a mixture of multiple substances, is it necessary to declare the percentage of each individual component within the mixture for registration, or is it sufficient to declare the mixture as a whole?
Answer
Subject: Cosmetic Registration and Ingredient Percentage
Hello,
Regarding cosmetic registration in Thailand and ingredient declaration, you are correct that INCI names are used.
For ingredients that are mixtures of several substances, the general practice in cosmetic regulations (like those followed in Thailand under the ASEAN Cosmetic Directive) is to declare the mixture using its INCI name. The components of the mixture are also typically listed using their INCI names, usually in descending order of concentration within the mixture.
The percentage declared in the product formulation or on the label usually refers to the percentage of the mixture in the final cosmetic product.
However, the specific requirements for declaring the components within the mixture, including whether you need to calculate and declare the percentage of each individual component within the mixture for the registration document itself, can depend on the nature of the mixture and the current detailed regulations from the Thai FDA.
Therefore, for the most accurate and definitive information regarding the exact requirements for declaring mixtures and their components during cosmetic registration in Thailand, it is highly recommended to consult directly with the Thai Food and Drug Administration (FDA) or refer to their official guidelines and documentation. They are the authoritative source for registration procedures.
