Low-Moisture HPMC Vegetable Capsules for Hygroscopic and Sensitive Formulations
Product Overview
For manufacturers dealing with hygroscopic powders or moisture-sensitive APIs, our HPMC hollow capsules offer the ultimate protective environment. Unlike gelatin, HPMC is chemically inert and does not contain amino acids, eliminating the risk of cross-linking reactions. These empty shells are derived from premium wood pulp, providing a stable, plant-based delivery system that remains flexible under low-humidity conditions. They are specifically designed for the modern "Clean Label" market while offering the mechanical reliability required for industrial-scale encapsulation.
Manufacturing Performance
Thermal & Humidity Stability: HPMC capsules do not become brittle in low humidity (as low as 2%), making them ideal for shipping to diverse climates.
Non-Reactive Material: Free from protein-based cross-linking, ensuring consistent dissolution rates throughout the product's shelf life.
Controlled Moisture Content: Typically between 4.0%-7.0%, protecting sensitive fills like probiotics and enzymes from degradation.
Enhanced Mechanical Strength: Our HPMC shells are toughened to withstand the mechanical stress of automated filling pins and hoppers.
Odorless & Tasteless: Provides a neutral container that effectively masks the strong scents of certain botanical extracts.
Key Market Sectors
Probiotic Manufacturers: Protects live cultures from moisture-induced activation.
Herbal & Botanical Brands: Ideal for high-potency extracts that absorb moisture from the air.
Hygroscopic Chemicals: Safe vehicle for mineral salts and amino acids that are incompatible with gelatin.
Global Wellness Brands: Essential for products requiring Vegan, Non-GMO, and Halal certifications.
Compliance & Traceability
Our production facility adheres to strict GMP protocols. Each batch is audited for dimensional accuracy and disintegration performance. We provide a full suite of certifications (ISO, Halal, Kosher, NSF) and ensure that all raw materials are 100% traceable to sustainable plant sources.
