Review and Questions on Whitening, Anti-aging, and V-shape Formulas

Asked by: jariya.bench On: April 19, 2014 Product Type: Cosmetics

Question

I have three cosmetic formulas and would like to ask for your review and advice on specific aspects:

  1. Whitening Formula:

    • Is this formula usable?
    • How should I incorporate Bisabolol (oil) into the water base, especially when using Light Cream Maker (HLB 2.5) which requires oil to form a cream? (Formula includes Light Cream Maker (HLB 2.5) and Bisabolol 1%)
    • Would adding Vitamin B3 and N-Acetyl Glucosamine be beneficial?
    • Is using Sea Kelp Bioferment at 5% acceptable, or will it cause excessive stickiness?
    • What is the expected pH, and is it compatible with the ingredients and skin?

  2. Anti-aging Formula:

    • Is this formula usable?
    • How should I incorporate Bisabolol into the water base? (Formula includes Bisabolol)
    • What is the expected pH, and is it compatible with the ingredients and skin?

  3. V-shape Formula:

    • Is this formula usable?
    • Is Pepha-Tight at 5% too high a concentration, potentially causing a tight, uncomfortable feeling?
    • How should I incorporate Bisabolol into the water base? (Formula includes Bisabolol)
    • What is the expected pH when using L-Carnitine at 3% and DMAE? Is the resulting pH suitable for skin?

  4. DMAE Calculation:

    • If I want to achieve a 4% concentration of active DMAE in a 100g product, is it correct that I need to use 20g of the liquid DMAE product?

Answer

Subject: Inquiry about product ingredients

Regarding your three formulas and questions:

  1. Whitening Formula:

    • The formula is usable, but modifications are needed.
    • Bisabolol is an oil and needs to be incorporated into the water base. Mixing it with FloraSolve (5%) before adding to the main water phase is recommended.
    • Light Cream Maker requires oil to form a cream. Since this formula has minimal oil (1% Bisabolol), it's suggested to make it a clear gel instead by adding a thickener.
    • Consider adding Vitamin B3 and N-Acetyl Glucosamine.
    • Sea Kelp Bioferment at 5% might feel slightly sticky but should be acceptable.
    • pH should be compatible.

  2. Anti-aging Formula:

    • The formula is usable.
    • Similar to the first formula, Bisabolol needs to be incorporated into the water base (e.g., using FloraSolve).
    • pH should be compatible.

  3. V-shape Formula:

    • The formula is usable, but modifications are recommended.
    • Pepha-Tight at 5% is quite high and might cause a tight, uncomfortable feeling. It's recommended to start with 2-3%.
    • Bisabolol needs to be incorporated into the water base.
    • Regarding pH, L-Carnitine at 3% is only slightly alkaline, and DMAE is acidic. The staff confirmed that the final pH should be a weak acid (6-7), which is generally compatible with skin. Measuring the pH after mixing is still a good practice, but adjustment might not be necessary.

Overall pH Compatibility:
Based on the feedback, the pH for formulas 1 and 2 should be fine. For formula 3, the staff indicated the pH will be a weak acid (6-7), which is generally compatible with skin, although skin's natural pH is lower.

DMAE Calculation:
Yes, your calculation is correct. If the total product weight is 100g, you should add 20g of the liquid DMAE product to achieve a 4% concentration of the active DMAE.
