HPMC vegetable capsules, often referred to as vegetarian capsules, were developed to cater to the preference for products that do not contain animal ingredients. They provide a convenient method for consuming medications and dietary supplements.
Vegetable capsules are produced using plant-derived substances like cellulose or HPMC. They provide a premium option for vegetarians and individuals with or without dietary limitations.
We offer performance additives for pharmaceuticals, including cellulose ethers for roles like suspending agents and binders. We also provide excipients such as dextrin, pregelatinized starch, and enteric film coating powder.
At LANDU, we offer a variety of pharmaceutical additives, including cellulose ethers, dextrin, pregelatinized starch, and enteric coating powder. We collaborate closely with customers to provide innovative solutions. Contact us for more product information.
HPMC serves as both a binder and a disintegrant. When dissolved in water, low-viscosity HPMC forms a clear, viscous colloidal solution, which reduces the drug’s contact angle and enhances its wettability.
Moreover, HPMC can expand significantly upon water absorption, increasing its volume by several hundred times, which greatly enhances the drug’s disintegration and dissolution rates.
Ethyl cellulose, which is insoluble in water, is used as a tablet binder, film coating, and barrier material. It plays a key role in making sustained-release tablets and microcapsules, preventing premature dissolution.
Additionally, it functions as a dispersant and stabilizer, protecting drugs from moisture and extending their shelf life.
Microcrystalline cellulose has a porous structure and high density, which makes it easily deformable. This gives it excellent drug loading capacity, strong dry adhesion, and effective disintegration. It can be compressed into tablets with high hardness and is commonly used as a filler, binder, and disintegrant.
Additionally, our products have excellent flowability, making them easy to mix with other excipients.
LANDU HPS product serves as an outstanding thickener and water retention agent, boosting product performance with a small amount. It is stable in both acidic and alkaline environments, has a lower gelatinization temperature than regular starch, and maintains stable viscosity despite temperature fluctuations.
Moreover, etherified starch provides enhanced freeze-thaw stability and clarity, making it suitable for diverse applications.
Low-substituted hydroxypropyl cellulose (L-HPC) is a non-ionic powder that swells rapidly in water, making it ideal for tablet production. It effectively enhances tablet disintegration and dissolution rates.
L-HPC’s structure improves tablet hardness and surface quality. Our products meet the standards of the Chinese, U.S., and European Pharmacopoeias.
Hydroxypropyl Methylcellulose Phthalate (HPMC-P) serves as an enteric coating agent, remaining insoluble in acidic conditions like gastric juice and dissolving rapidly in the small intestine. This characteristic is ideal for ensuring active ingredients are released at the appropriate site.
HPMC-P is a modified cellulose polymer with hydroxyl groups replaced by methyl ethers, 2-hydroxypropyl ethers, or phthalyl esters. It comes in various grades depending on molecular weight and is a white or slightly off-white, free-flowing, odorless powder.
Hypromellose Acetate Succinate (HPMCAS) serves as an enteric and film coating for oral medications. It improves solubility by staying intact in the stomach and dissolving in the intestines. Application can be done using triethyl citrate in aqueous or organic solutions.
HPMCAS can be mixed with other binders to achieve sustained-release effects. Methods such as milling and extrusion are employed to enhance the dispersion of drugs with low solubility.
Pharmaceutical Grade Carboxymethyl Cellulose (CMC) is highly versatile in oral medications. It helps in shaping the medicine and enhances its digestion and absorption.
In ointments, CMC functions as a dispersant and moisturizer. In syrups, it acts as a suspending agent, emulsifier, and stabiliz
