Mosquito Repellent Cream Formula

Regarding the formula you have planned and your question about the amount of Citronella Oil, according to the staff's recommendation, the appropriate amount to use Citronella Oil as an active ingredient for mosquito repellent is 10%. This is the maximum recommended level for effectiveness against Aedes mosquitoes.

For the other ingredients you have chosen:

• Allantoin (0.5%): This ingredient helps reduce irritation and allergic reactions, which is beneficial for soothing the skin from mosquito bites. The 0.5% you are using is within the recommended range for solubility in water at room temperature and is a generally recommended usage rate.
• Lipidsoft (5%): This is an emollient that helps the cream spread easily and provides a soft, smooth feel on the skin. The 5% amount is within the recommended usage range (1-20%).
• Light Cream Maker™ (1%): This is an oil-in-water (O/W) emulsifier that helps create a light, easy-to-spread, and fast-absorbing cream texture. The 1% amount is within the recommended usage range (0.5-3%) and is a common recommended amount.
• Nature preserve (1%): This is a natural preservative that helps prevent microbial growth in the formula. The 1% amount is within the recommended usage range (0.75-2.0%) and is close to the generally recommended amount (1.25%).

The staff also advised that if the main purpose of the formula is solely mosquito prevention, the ingredients you have selected are sufficient.

Therefore, you can proceed with your planned formula, adjusting the Citronella Oil amount to 10% to achieve the best mosquito repellent efficacy.
