Hydroxypropyl-beta-cyclodextrin is a purified polydisperse product resulting from the controlled reaction of native beta-cyclodextrin. Hydroxypropyl beta-cyclodextrin is itself very soluble in water (greater than 500 mg/ml at room temperature compared to 18 mg/ml for beta-cyclodextrin), and is used for molecular encapsulation of a variety of sparingly water compounds to enhance the aqueous solubility of the encapsulated compound.

Hydroxypropyl Beta Cyclodextrin can prevent evaporation of volatile substances maintaining the stability of its nutrients, get rid of the terrible smell and can significantly enhance the effects of emulsification with the combined use of food emulsifiers. Hydroxypropyl Beta Cyclodextrin can also make preservative of food release slowly, raise the effect of anti-corrosion and extend the shelf life of food.
Hydroxypropyl beta cyclodextrin used as stabilizer, emulsifier and odor absorber.

A1: Hydroxypropyl-beta-cyclodextrin is a purified derivative of native beta-cyclodextrin. It is highly water-soluble and encapsulates poorly water-soluble molecules within its molecular structure, thereby significantly increasing their aqueous solubility.
A2: In the food industry, it helps prevent the evaporation of volatile nutrients, masks unpleasant odors, enhances the action of food emulsifiers, and enables the controlled release of preservatives to extend the product's shelf life.
A3: In cosmetic formulations, it functions as an effective stabilizer, emulsifier, and odor absorber to enhance formula performance and shelf-life stability.
A4: Hydroxypropyl-beta-cyclodextrin is exceptionally soluble in water, reaching over 500 mg/ml at room temperature, which is significantly higher than the 18 mg/ml solubility limit of native beta-cyclodextrin.
A5: For small quantities like 1kg, packaging features double plastic bags with an aluminum foil bag inside a protective box. For larger bulk orders (10kg, 25kg, or more), robust drums or cartons lined with two layers of plastic bags are used.
A6: Depending on weight, we offer express delivery via EMS, DHL, UPS, and FedEx (3-7 days door-to-door for smaller shipments), air freight (3-7 days to airport), and ocean freight (10-35 days to port for bulk orders over 100kg).
