Clarification on Ichthammol Usage Percentage in Different Formulations
Question
The usage percentage for Ichthammol (Product ID: 2051) is listed with a broad range (5-20%) in the manual, but in my specific formulation (e.g., cream), I can only use a much lower percentage (0.1-1%). Could you please clarify why there is such a difference in recommended usage rates and provide guidance on the appropriate percentages for various product types like creams, wash-off products, and shampoos?
Answer
Based on the information for Ichthammol (Pure, 99%) (Product ID: 2051), the usage rates provided in the product description vary depending on the intended application and product format.
- For application on insect bites/stings to reduce itching, swelling, redness: 10-20%
- For skin application to reduce itching, redness, and moisturize: 5%
- For use in bath/body/facial cleansing products for acne (wash-off): 2-3%
- For use in shampoo to reduce scalp itching, excess oil, dandruff: 1%
- For use in skin care creams to reduce excess oil, acne (leave-on): 1%
- General usage rate: 0.1-5%
The 5-20% range you saw might refer to specific applications like treating insect bites. However, for other product types like skin care creams or wash-off products, the recommended rates are lower, around 0.1-5% or 1-3%, which aligns with your experience of using 0.1-1% in your formulation.
Therefore, the difference you observed is due to varying recommended concentrations for different uses, not a bug on the website.
