Moisturizers are essential skincare formulations designed to maintain optimal skin hydration. Far from being exclusive to dry skin, they are a fundamental staple for all skin types—including oily, combination, and sensitive skin. While standard moisturizers hydrate and lock in moisture at the surface, innovative, highly safe, fermented ingredients like polyglutamic acid (PGA) can penetrate into the deeper epidermal layers, delivering vital moisture and nutrients for advanced, deep-tier skin care.
Complementing this deep hydration, film-formers utilize specialized polymers to create a cohesive, flexible, and continuous matrix on keratinous surfaces. This protective "second skin" provides a long-lasting barrier that meets evolving consumer demands for superior efficacy. Greenwood Bio’s pullulan stands out as a premium film-former and versatile platform for innovation, widely utilized in high-performance facial masks, cosmetic creams, lotions, and mascaras.
Traditionally, preservatives are synthetic compounds used to inhibit microbial growth and extend the shelf life of pharmaceuticals, cosmetics, biologics, and food. Greenwood Bio redefines this standard by offering 100% fermented, bio-based preservatives derived from natural raw materials like glucose, yeast, and premium bacterial strains. Our solutions prioritize safety without compromising performance; for instance, our core offerings, Nisin and Natamycin, are fully recognized as GRAS (Generally Recognized as Safe).
Expanding beyond traditional applications, our ε-Polylysine (Epsilon Poly-L-Lysine) provides a powerful, broad-spectrum defense against Gram-positive bacteria, Gram-negative bacteria, molds, and yeasts. Produced naturally through the aerobic fermentation of Streptomyces albulus, ε-Polylysine delivers exceptional efficiency, making it an ideal clean-label preservative for beverages, processed meats, and diverse food products.
While widely recognized in the food industry, natamycin is also a highly effective, though less widely known, topical ophthalmic antifungal agent. As a tetraene polyene macrolide antibiotic derived from Streptomyces natalensis, it exhibits robust in vitro activity against a broad spectrum of yeasts and filamentous fungi, including Candida, Aspergillus, Cephalosporium, Fusarium, and Penicillium.
Complementing our biopolymer portfolio, pullulan is a naturally occurring exopolysaccharide produced through the fermentation of specific yeast-like fungal strains, notably Aureobasidium pullulans. Highly valued for its exceptional film-forming, binding, and barrier properties, this versatile carbohydrate is extensively utilized across the pharmaceutical, cosmetic, and food industries to drive premium product innovation.
