Hydroxypropyl-beta-cyclodextrin HPCD CAS No.:128446-35-5 /94035-02-6 Introduction:
H&Z® Hydroxypropyl-beta-cyclodextrin: Hydroxypropyl beta-cyclodextrin are purified polydisperse products resulting from the controlled reaction of propylene oxide and 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 CAS No.:128446-35-5 Function
In Food
Hydroxypropyl beta cyclodextrin could increase the stability of molecular nutrition and long-time effect,cover up or adjust bad smell and tastes of food nutrition molecular,improve production process and product quality and extend the shelf-life.
In Cosmetics
Hydroxypropyl beta cyclodextrin used as stabilizer,emulsifier and odor absorber.It could reduce organic molecules stimulation to skin mucosal and enhance the stability of the effective components.Prevent volatile ,oxidation of nutrient composition ,increase the solubility of insoluble flavours and fragrances and keep the fragrance slow releasing and lasting.
