Soy Extract Type and Penetration Enhancer Comparison

Question

I have two questions regarding ingredients:

  1. Is Soy Extract (Isoflavones / Genistein) non-denatured?
  2. Is there comparative data on the effectiveness of Laurocapram versus 1,2-Hexanediol + PE1-Aqua as penetration enhancers? If so, which is more effective for skin penetration, disregarding W/O or W/W formulation type?

Answer

Based on the provided information:

  1. Regarding the Soy Extract (Isoflavones / Genistein) product (ID 302), it is stated that it is denatured.
  2. Regarding the comparison of penetration enhancers (Laurocapram (ID 1585) vs. 1,2-Hexanediol (ID 886) + PE1-Aqua (ID 856)):
    • There is no comparative test data available.
    • The effectiveness of penetration enhancers varies depending on the specific substance being transported, and there is currently no complete understanding or model to predict which enhancer will be most effective for a given substance.
