Food Grade Hydroxypropyl-Beta-Cyclodextrin (HPBCD) 99% Powder
Food Grade Stabilizer
Hydroxypropyl-Beta-Cyclodextrin (HPBCD) Powder
Most formulators know beta-cyclodextrin for its cavity, but its poor water solubility limits use — Hydroxypropyl-Beta-Cyclodextrin (HPBCD, CAS 128446-35-5) solves that by adding hydroxypropyl groups through controlled etherification with propylene oxide. The result, supplied by Demeter in Shaanxi as a 99% food-grade powder, dissolves freely in water and forms inclusion complexes that trap hydrophobic actives, lifting both solubility and stability in the final product. We hold every lot to 99% by HPLC and ship a white to off-white powder that works as a stabilizer, solubilizer, and carrier across food and beverage formats. Buyers get factory-price bulk supply with OEM, private label, and free-sample support, plus a COA on each batch.

Key Highlights
01
99% food-grade HPBCD — standardized by HPLC, white to off-white powder from Shaanxi, China.
02
Molecular encapsulation — the hydrophobic cavity traps poorly soluble actives to raise aqueous solubility and stability.
03
High water solubility — freely soluble above 500 mg/mL at room temperature, far beyond native beta-cyclodextrin (~18 mg/mL).
04
Multifunctional stabilizer — works as solubilizer, emulsifier aid, and odor absorber in food, beverage, and cosmetic systems.
05
Low-irritation carrier — biocompatible material profile suited to oral and topical formulation formats.
06
OEM / private label / free sample — MOQ from 1 kg, factory price, COA with every lot.

Function & Wellness
Rapid solubilization
Traps hydrophobic molecules so they disperse in water instead of floating or settling.
Stable complexing
Shields enclosed actives from light, heat, and oxidation in the finished good.
Clean carrier
Low-irritation, biocompatible profile suited to food and topical formats.
Process friendly
Freely soluble in cold and hot water with no precipitation at working concentration.
Applications
Food & Beverage
Keeps volatile aromas from evaporating and supports even emulsification.
Cosmetics
Keeps cosmetic actives evenly dispersed and helps tone down raw-material odors in creams and serums.
Nutraceuticals
Carries lipophilic plant extracts for better mix-in within blends.
Flavor & Ingredient Carriers
Softens harsh or bitter notes and spreads encapsulated material gradually through the product.
Lab & Analytical
Serves as a complexing host for hydrophobic reagents in testing work.
