Cosphaderm® Zinc Lactate natural (INCI: Zinc Lactate) is a 100% naturally derived, multifunctional antimicrobial powder. Produced via a high-purity biofermentation process, this zinc salt of lactic acid is a “clean-label” powerhouse. It bridges the gap between high-performance preservation and active skincare by providing broad-spectrum defense while simultaneously supporting the skin’s biological barrier and recovery mechanisms.
Key Benefits and Performance
-
Dual-Action Active:
-
Zinc Fraction: Supports skin homeostasis, strengthens antioxidant defense, and aids in the recovery from UV-induced damage. It is also highly effective at neutralizing odor-causing bacteria.
-
Lactic Acid Fraction: A core component of the skin’s Natural Moisturizing Factor (NMF). As a gentle AHA, it acts as a superior humectant, pulling moisture into the stratum corneum.
-
-
Broad-Spectrum Preservation Support: It delivers strong antimicrobial efficacy against bacteria and yeasts, requiring some support for antifungal protection. Its activity is pH-independent, meaning it remains active in neutral and high-pH formulations where organic acids fail.
-
Targeted Odor Control: Its ability to inhibit the metabolism of odor-producing microorganisms makes it an ideal natural active for deodorants.
-
Oral Care Specialist: Due to its antibacterial properties and safe profile, it is frequently used in natural toothpastes and mouthwashes to combat plaque-forming bacteria.
-
Synergistic Flexibility: While it has partial activity against moulds, it is designed to be paired with other natural boosters to create a robust, fail-safe preservation system.
Formulation Guidelines
-
The “Mould Gap” Strategy: To achieve full-spectrum security (especially against A. brasiliensis), the supplier recommends combining it with Cosphaderm® Pentiol Natural, Cosphaderm® CHA, or Cosphaderm® Magnolia Extract 98
