Unlock Next-Level Hydration: Meet DropCare® PGA70 & PGA01 – Your Smart Molecular Weight Choice

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

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
