Clarifying Usage Percentage of Apple Stem Cell Extract and CoA Interpretation
คำถาม
I saw a document (possibly a Certificate of Analysis) for a raw material containing Apple fruit cell culture extract, stating it contains 9% of the extract. Does this mean the finished cosmetic product using this raw material contains 9% Apple fruit cell culture extract? Is using a high percentage like this beneficial or safe, or could it cause adverse effects?
คำตอบ
Apple Stem Cell Extract Usage Rate
Regarding the usage rate of Apple Stem Cell Extract, the manufacturer recommends a usage rate of 0.5-5%, with a specific recommendation of 3%. While it can be used up to 5%, using a percentage as high as 9% of the raw material in the final product is significantly above the manufacturer's recommended maximum.
As previously explained by the staff, a Certificate of Analysis typically shows the composition of the raw material itself (e.g., the raw material contains 9% Apple fruit cell culture extract), not the percentage of this raw material used in the final cosmetic product. A brand might use only a small percentage of this raw material in their formulation.
Using an ingredient at a concentration higher than the manufacturer's recommended maximum does not necessarily increase its effectiveness and can potentially lead to adverse effects such as skin irritation or sensitivity. It is generally best to adhere to the recommended usage rates provided by the raw material manufacturer for optimal results and safety.
