Cosphaderm® Magnolia Extract 98 (INCI: Magnolia Officinalis Bark Extract) is a 100% natural, highly purified active obtained through a sustainable supercritical CO₂ extraction process. It is standardized to contain 98% of the bioactive neolignans Magnolol and Honokiol. This off-white powder is a premier “clean-label” multi-tasker, offering potent broad-spectrum antimicrobial protection alongside clinically recognized antioxidant and anti-inflammatory benefits.
Key Benefits and Performance
-
Potent Broad-Spectrum Defense: Unlike many botanical extracts, it offers a comprehensive antimicrobial spectrum. It is particularly valued for its efficacy against moulds, a common weak point in natural preservation.
-
Universal pH Independence: Its activity is entirely physical/biological and does not rely on pH-sensitive ionization.
-
Anti-Acne & Oral Care Specialist: It demonstrates high-performance bacteriostatic activity against Propionibacterium acnes and Streptococcus mutans (caries-causing bacteria), making it ideal for specialized blemish-control and dental care.
-
Advanced Anti-Ageing & Calming: As a powerful free radical scavenger, it protects skin cells from oxidative stress. Its anti-inflammatory properties help reduce skin redness and “inflamm-ageing,” positioning it as a premium anti-ageing active.
Formulation Guidelines
- The “Synergy Strategy”: While powerful, it is most efficient when used as a “hurdle” in a system. The supplier recommends combining it withCosphaderm® GMCY RSPO MB or Cosphaderm® Pentiol Natural to achieve maximum broad-spectrum security.
- Solubility: Dispersible in water; soluble in alcohols, glycols, and many cosmetic oils.
-
Pro-Tip: Pre-dissolving the powder in a glycol (like Pentylene Glycol) or a liquid emulsifier before adding to the formulation ensures even distribution and prevents “specking.
