Clarifying 100% Usage Rate for MYFerment™ Barrier and Using 40% in Water Phase
Question
I am formulating a product using MYFerment™ Barrier (Lactococcus Ferment Extract). The recommended usage rate for this ingredient is listed as 100%. I need confirmation on whether this 100% rate is correct.
Furthermore, I plan to use this ingredient at approximately 40% to replace a significant portion of the water phase in my formulation. Is using 40% an appropriate and effective concentration for achieving the desired results?
Answer
The usage rate of 100% for MYFerment™ Barrier (Lactococcus Ferment Extract) is technically correct, but it requires clarification based on how these types of ingredients are supplied.
Clarification on 100% Usage Rate
- Safety and Supply: When a water-based active ingredient like this ferment filtrate/lysate is listed with a 100% usage rate, it means the raw material itself is safe, non-toxic, and non-irritating enough to be used as the entire water phase of a formulation, or even applied neat. It indicates that the supplier does not set a maximum usage limit based on safety concerns.
- Formulation Context: The 100% rate is a statement of safety, not necessarily a recommendation for typical use, as it would be cost-prohibitive for most products.
Your Plan to Use 40%
Your plan to use MYFerment™ Barrier at approximately 40% to replace a portion of your water phase is an excellent and highly effective approach.
- Maximizing Efficacy: Using it at this high concentration (40%) will maximize the delivery of the active components (peptides, amino acids, and metabolites) that are responsible for its skin barrier benefits, such as upregulating key structural proteins like filaggrin and involucrin.
- Typical Usage: While 100% is possible, formulators commonly use this type of high-concentration active water or lysate in the range of 10% to 50% of the total formula to achieve significant results while managing cost. 40% is considered a high-performance concentration for this ingredient.
