คำถาม

My lotion formulation leaves a white cast and is slow to absorb, requiring a lot of rubbing. I used ingredients like stearic acid, stearyl alcohol, and Cetyl Alcohol.

What is causing this issue and how can I fix it to get a clear, fast-absorbing texture?

คำตอบ

Hello,

The issue of your lotion leaving a white cast and requiring extensive rubbing to absorb is caused by some of the ingredients you are using.

Cause of the white cast:
Ingredients like Stearic acid, Stearyl alcohol, and Cetyl Alcohol are fatty alcohols and fatty acids that often contribute to a whitening effect on the skin and result in a heavier texture that is slow to absorb.

Recommended adjustments for a clear, fast-absorbing texture:
To achieve a lighter, faster-absorbing lotion that doesn't leave a white residue, it is recommended to adjust the main ingredients following the staff's advice:

  1. Avoid using Stearic acid, Stearyl alcohol, and Cetyl Alcohol in this formulation.
  2. Choose a different Emulsifier/Thickener:
    • Use Wax Cream Maker (e.g., PEG-8 Beeswax) at approximately 3%.
    • Or use Beeswax at 3-5% (adjust based on desired thickness).
  3. Limit the oil phase to no more than 20% of the total formula.
  4. Other ingredients: You can add other water-soluble and oil-soluble ingredients as needed.
  5. Preservative: Remember to include a preservative at approximately 1% to prevent spoilage.

This approach should help you achieve a lotion with a lighter texture that absorbs more easily and quickly without leaving a white cast on the skin.
