High-Molecular-Weight Polymer

The PGA Revolution: One Ingredient, Two Powerful Profiles In the quest for breakthrough hydrators, Polyglutamic Acid (PGA) has emerged as a game-changer. But not all PGAs are created equal. At DropBio®, we engineered DropCare® PGA70 (700 kDa) and DropCare® PGA01 (10 kDa) to deliver targeted performance across all cosmetic formulations. Here’s why molecular weight matters: The Science Behind PGA Sodium Polyglutamate is a natural, fermentation-derived polymer with a unique γ-peptide bond structure (linking α-amino and γ-carboxyl groups). Its secret lies in: 5000%+ water-binding capacity (outperforming hyaluronic acid) Dense carboxyl side chains forming H-bond networks Biofilm-forming ability that locks moisture into skin Tailored Solutions: Molecular Weight Magic Property DropCare® PGA70 (700 kDa) DropCare® PGA01 (10 kDa) Primary Function Surface Film-Former Deep Skin Penetrator Texture Velvety-thick Featherlight Key Benefits • 24H barrier-locking hydration• Wrinkle-smoothing film• Enhances product spreadability • Boosts NMF synthesis• Transports actives deep into skin• Instant plumping effect Best For Creams/Masks/Leave-on products Serums/Toners/Rinse-off formulas Proven Efficacy: Beyond Basic Moisturization Both variants deliver multi-mechanistic anti-aging results:✅ 3X Hyaluronic Acid Boost (in-vivo data)✅ 28% Reduction in TEWL after 4 weeks✅ 19% Improvement in skin elasticity✅ Melanin Inhibition for brightening Why Formulators Choose DropCare® ▶ PGA70 (700 kDa) – The Shield Creates breathable moisture-trapping mesh Perfect for high-viscosity anti-aging creams Use at 0.5-1.0% for cushion-like texture ▶ PGA01 (10 kDa) – The Spear Penetrates stratum corneum in <30 sec Ideal for watery essences & boosters Effective at 0.1-0.5% with zero tackiness Application Genius Pair them for synergistic effects: Cleanser: PGA01 (0.2%) → Preps skin for absorption Toner: PGA01 (0.3%) + PGA70 (0.1%) → Multi-depth hydration Cream: PGA70 (0.8%) → Seals in active ingredients If you are interested in our products and want to know more details, please contact judyzhou@drop-bio.com.
