Understanding Repair Activator™ Forms and Efficacy

You asked about the difference in efficacy between Repair Activator™ in powder and liquid forms at specific concentrations (1% powder vs 15% liquid).

Based on the available product information, there isn't a product explicitly named "Repair Activator™ Powder". However, there is a highly concentrated form called Bifida Repair Complex™ (High Conc) which contains 4.5-5.5% dry residue of Bifida Ferment Lysate and is recommended for use at 1-7% for high efficacy. This might be the product you are referring to as the "powder" form, or it represents the highly concentrated active ingredient used in such a form.

The liquid forms available include Repair Activator™ BG (Butylene Glycol base) and Repair Activator™ WS (Water base). These are recommended for use at a much higher rate, from 5% up to 100%.

To compare the efficacy of your two proposed formulations, we need to consider the amount of the active ingredient, Bifida Ferment Lysate, in the final product:

• Repair Activator™ Powder (assuming Bifida Repair Complex™ High Conc) at 1%: Using 1% of Bifida Repair Complex™ (which contains 4.5-5.5% active dry residue) results in approximately 0.045% to 0.055% active Bifida Ferment Lysate in the final formulation.
• Repair Activator™ Liquid (assuming Repair Activator™ BG or WS) at 15%: The exact concentration of active Bifida Ferment Lysate in the standard liquid forms is not specified, but their high recommended usage rate (5-100%) suggests the active concentration within the liquid itself is lower than the High Conc version. However, using it at 15% in your formula provides a significant amount of the liquid product. If we estimate the active content in the standard liquid forms, using 15% of the liquid product is likely to result in a higher concentration of active Bifida Ferment Lysate in the final formula compared to using 1% of the highly concentrated form.

Therefore, based on the typical concentrations and recommended usage rates, the formulation using Repair Activator™ Liquid at 15% would likely be more effective than the formulation using Repair Activator™ Powder (or Bifida Repair Complex™ High Conc) at 1%, as it is expected to deliver a higher amount of the key active ingredient, Bifida Ferment Lysate, into the final product.
