Manufactured in GMP compliant facilities and certified ISO9001 using the latest chromatographic purification techniques for pharmaceutical-grade purity. Our product satisfies high standards of antibacterial effectiveness and bioactive stability. With 30 technical professionals and extensive testing facilities, we guarantee the molecular integrity (C18H16O7, MW: 344.32) from each manufacturing batch, overcoming major formulation issues for dermatological medicines and natural preservation systems.
What Is Lichen Extract?
The product is a high concentration botanical active ingredient obtained from symbiotic organisms of fungus and algae. The major bioactive ingredient, Usnic acid (CAS: 125-46-2), has a high antibacterial activity against gram-positive bacteria and good environmental stability.
This extract is a natural alternative to synthetic preservatives, which are limited by regulation, to fight microbial contamination of personal care products. Due to its dibenzofuran composition, it may specifically disrupt bacterial metabolic pathways without eliciting typical resistance mechanisms.
The extraction procedure utilises selected solvent systems and crystallisation protocols to provide a standardised potency that is higher than whole-lichen preparations. This standardisation solves industrial problems with uniformity of dose and regulatory compliance in commercial applications.

Functions
The product contains Usnic acid providing multi-dimensional bioactive performance:
Antimicrobial Efficacy: Active against Staphylococcus aureus and Streptococcus spp. Suitable for acne cosmeceuticals. The medication prevents bacteria from making ATP and has sustained antibacterial effects in lipid-rich matrices.
Decreases inflammatory mediators via cyclooxygenase pathways. This methodology is advantageous for wound healing and sensitive skin care formulations, free of synthetic corticosteroids.
Antioxidants: prevents lipid peroxidation in emulsion systems by free radical scavenging. It inhibits the oxidation of active substances during the storage and prolongs the product shelf life.
Application Fields
Pharmaceutical Development: Used in topical antibacterial ointments to treat superficial skin infections. Due to its lipophilic properties, it may penetrate the stratum corneum and reach therapeutic quantities at the site of infection.
Cosmetic Formulations: Used in anti-acne serums, blemish treatments and deodorant products. Extracts have an anti-microbial and anti-inflammatory effect that may help to fight the germs that cause the problem and the inflammation that accompanies it.
Natural Preservation Systems: Used as a bio-preservative in oil-based cosmetics when water-soluble parabens are not very effective. It controls microbiological growth in anhydrous formulations without detriment to the appearance of the product.
