Description of Hydroxypropyl-Gamma-Cyclodextrin

Hydroxypropyl-Gamma-Cyclodextrin (HP-γ-CD) is a modified cyclodextrin derived from gamma-cyclodextrin by introducing hydroxypropyl groups into its molecular structure. It has a hydrophilic exterior and a relatively hydrophobic cavity, allowing it to form inclusion complexes with various poorly water-soluble molecules.

HP-γ-CD is highly water-soluble and can improve the apparent solubility and stability of suitable guest compounds. Its inclusion properties make it useful as a solubilizing agent, formulation excipient, and molecular encapsulation material in pharmaceutical, food, cosmetic, and chemical research applications.

Applications

Pharmaceutical Formulation

Used as a pharmaceutical excipient to improve the apparent water solubility of poorly water-soluble active pharmaceutical ingredients (APIs).
Drug Delivery

Used to form inclusion complexes with suitable drug molecules, which can help improve their aqueous solubility, physical stability, and formulation performance.
Solubility Enhancement

Used as a solubilizing agent for hydrophobic or poorly water-soluble compounds in formulation and pharmaceutical development.
Stability Improvement

Can be used to help protect suitable guest molecules from environmental factors such as oxidation, light, or other degradation pathways through inclusion-complex formation.
Controlled Drug Release Research

Used in pharmaceutical research and drug-delivery systems where cyclodextrin–drug interactions are investigated to modify the release or handling characteristics of active compounds.
Cosmetic Formulations

Used in cosmetic and personal-care research to encapsulate or solubilize selected functional ingredients, fragrances, and other poorly water-soluble components.
Food and Flavor Applications

Used in research involving the encapsulation and stabilization of selected flavors, aromas, and other hydrophobic food ingredients.

Hydroxypropyl-Gamma-Cyclodextrin 's supply advantage and supply capability

When purchasing Hydroxypropyl-Gamma-Cyclodextrin CAS 99241-25-5, experienced buyers normally look beyond the catalog name. The questions are practical: Is the material consistent from batch to batch? What is the degree of substitution? What analytical method is used? Can the supplier provide a current COA and SDS? Can the same specification be maintained for the next purchase?

At Zhishang Chemical, we supply specialty chemicals and pharmaceutical-related raw materials for international B2B customers. For HP-γ-CD bulk supply, we focus on specification confirmation, raw material control, processing, quality inspection, packaging and shipment coordination. This gives procurement teams a clearer process from initial sample evaluation to repeat purchasing.

Hydroxypropylation is the key modification behind this material. In general, hydroxypropyl groups are introduced onto the cyclodextrin structure to alter its physicochemical properties. Published cyclodextrin research shows that hydroxypropyl modification can substantially improve the water compatibility of cyclodextrin systems and influence inclusion and solubilization behavior.

For buyers evaluating a Hydroxypropyl-Gamma-Cyclodextrin manufacturer in China, we recommend confirming the exact grade before quotation. This is particularly important because hydroxypropyl cyclodextrins are not always represented by one simple molecular structure; substitution level and product specifications can affect the material’s molecular-weight characteristics and performance.
