Applications of γ-Cyclodextrin
- Pharmaceutical-grade gamma-Cyclodextrin can be used directly as a pharmaceutical excipient in human formulations.Especially for solubilizing poorly soluble drugs.It helps improve the stability and biosafety of drugs.
- Pharmaceutical-grade γ-Cyclodextrin can be used in inclusion complexation techniques to modify the physical state of drugs while preserving their chemical properties.For example, pulverizing liquid drugs can help solve practical problems in drug production and use.
- Cosmetic-grade gamma-Cyclodextrin serves as an energy carrier for active ingredients in cosmetics.Compatible with all cosmetic systems, including water-based and cream-based products.
- Cosmetic-grade gamma-Cyclodextrin can be used as a stabilizer or carrier in daily chemical products.This addresses the fundamental issues of being difficult to stabilize, dissolve, and cause irritation.
- Food-grade gamma-Cyclodextrin is a core additive for high-end preservation, flavor enhancement, and functional improvement. It can be broken down by human digestive enzymes and is non-toxic and harmless.For example, the encapsulation and preservation of flavorings and colorings;Encapsulation of bitter and spicy functional components enhances the taste;It can also be used as a thickener and stabilizer in sauces, ice cream, etc., to improve the uniformity of texture.
- Industrial-grade γ-Cyclodextrin is a low-cost functional additive.It can be used for wastewater treatment (which is beneficial for realizing the resource utilization of oil pollution);Supports for industrial catalysts (which help improve catalyst stability and reaction efficiency);Textile/material modification (beneficial for improving the stability of material processing);Industrial fragrances and flavorings (which help reduce volatilization losses during production and storage), etc.
