Water-Based Lotion Formula Adjustments for Normal/Oily Skin (Daytime Use)

Asked by: gana41193 On: May 23, 2018 Product Type: Cosmetics

Question

I have a water-based lotion formula for normal to slightly oily skin, intended for daytime use. Based on the feedback received:

  1. Can this formula be mixed and used as is, or are adjustments needed to the ingredients or percentages?
  2. For the water-soluble ingredients, is there a specific order of addition required (e.g., adding before/after others) or can they be added directly to the water phase?
  3. If I prefer not to use Urea (Hydro-Urea® Liquid), what alternative ingredients can be used to maintain effectiveness, considering its role in Natural Moisturizing Factor (NMF) alongside Sodium PCA and Sodium Lactate?

Answer

Formula Feedback and Recommendations

Based on the staff's feedback for your water-based lotion formula aimed at providing moisture for normal to slightly oily skin, here are the recommendations:

  • Ingredients to Remove: To avoid stickiness, especially for daytime use, it is recommended to remove Hydro Protein and Soy Extract (Isoflavones / Genistein).
  • Ingredients to Reduce: Reduce the percentage of Sodium PCA 50%, Sodium Lactate Plus, and Snail Secretion by at least half.
  • Remaining Ingredients: The other ingredients in your list are considered suitable.

Answers to your specific questions:

  1. Can this formula be mixed as is, or are adjustments needed?
    Adjustments are recommended as per the staff's feedback for your specific skin type and intended use (daytime).
  2. Do the water-soluble ingredients need a specific order of addition?
    No, all listed ingredients are water-soluble and can be added directly to the water phase gradually with gentle stirring or mixing.
  3. If I don't want to use Hydro-Urea® Liquid, what can replace it?
    You can omit Hydro-Urea if you prefer not to use it. Sodium PCA and Sodium Lactate are effective moisturizers on their own and can provide sufficient hydration, particularly as your skin is not severely dehydrated.
