Clarification on adjusting cream formulation ingredients and alternative preservatives for acne-prone skin
คำถาม
Regarding the staff's recommendation to check Fragrance, Natural Oil, and Phenoxyethanol in a cream formulation causing acne:
1. Does "checking" mean reducing the proportion of these three ingredients in the formula, or removing them?
2. For the preservative Phenoxyethanol, are there other preservatives that are effective and cause less irritation?
คำตอบ
Hello,
Regarding your questions about the cream formulation causing acne:
When the staff suggested checking the Fragrance, Natural Oil, and Phenoxyethanol, it means you should test by either reducing the percentage of these ingredients in your formula or removing them one by one to identify which ingredient might be causing the acne.
For alternative preservatives that are effective and potentially less irritating than Phenoxyethanol, the staff recommended considering Mild Preserved (Ethylhexylglycerin + Caprylyl Glycol) or Phenoxyethanol SA (Phenoxyethanol + Sorbic Acid). You can explore these options as alternatives.
It's important to identify the specific ingredient causing the issue rather than just adding ingredients to reduce irritation, as suggested by the staff initially.
