Cosmetic Ingredient Labeling for Blends (e.g., Butter Cream Maker)

According to Thai FDA regulations for cosmetic labels, ingredients are generally listed in descending order of concentration (w/w).

When using a blend like "Butter Cream Maker" where the exact percentages of its components (Cetyl Alcohol, Glyceryl stearate, CETETH-20) are not known, there are two ways to handle the ingredient listing, as advised by the staff:

1. Obtain the detailed composition: Contact customer service at care@myskinrecipes.com to request the exact percentage breakdown of each component within the "Butter Cream Maker" blend. Once you have these percentages, you can list Cetyl Alcohol, Glyceryl stearate, and CETETH-20 individually in your product's ingredient list, ordered according to their respective percentages (which would be a portion of the 4% total).

2. List the components as a group: You can list the components of the blend together on the label using "(and)". For your example, this would be listed as:
   Cetyl Alcohol (and) Glyceryl stearate (and) CETETH-20
   This combined entry would be placed in the overall ingredient list based on the total concentration of the blend used (in your case, 4%). This method is acceptable according to the staff's advice when the individual percentages within the blend are not readily available.
