Hydroxypropyl Alpha Cyclodextrin for Cosmetic Skin Care is a water-soluble cyclodextrin derivative developed for cosmetic and fine chemical formulations. Produced by Binzhou Zhiyuan as a direct factory supply, this material supports stability and controlled release of active ingredients in skin care products, with heavy metal levels controlled to meet skin-safe application requirements. It is available in flexible packaging sizes to accommodate varying scales of commercial procurement and formulation development.
Hydroxypropyl alpha cyclodextrin appears as a white or almost white powder, with no odor and a slightly sweet taste. It is freely soluble in water, soluble in methanol and ethanol, and almost insoluble in acetone and trichloromethane. This solubility profile allows it to integrate into aqueous and partially alcoholic cosmetic bases, supporting compatibility with common formulation systems used in skin care production.
As a cyclodextrin derivative, this material acts as a host molecule to encapsulate active ingredients within its cavity structure. This encapsulation helps improve the stability of sensitive actives against degradation from light, heat, or oxidation during storage and use. It also supports controlled release of active components upon application, supporting consistent performance in skin care products. Its defined heavy metal limit makes it suitable for both leave-on and rinse-off skin care formulations designed for direct skin contact.

This product uses alpha cyclodextrin as the starting material. It undergoes a one-step hydroxyalkylation reaction with propylene oxide under alkaline conditions to produce a crude product liquid. The crude liquid is first decolorized with medicinal carbon, then processed through one-stage ultrafiltration to remove macromolecular impurities, followed by nanofiltration for separation, purification and concentration. After pH adjustment, a second stage of ultrafiltration is applied to remove bacteria. The final dry powder finished product is obtained through spray drying. No special reaction conditions are required during the synthesis process.
The production workflow includes multiple purification and filtration steps designed to reduce impurities and control microbial load. Decolorization and multi-stage filtration work to remove unwanted components, while the final spray drying process produces a uniform, easy-to-handle powder. These steps align with the product’s specified limits for heavy metals and microbial indicators, supporting consistent batch-to-batch performance in cosmetic applications.
The product uses a two-layer packaging structure for protection. The inner layer is a PE bag, enclosed in an aluminum foil bag for moisture and light barrier. Outer packaging options include cartons or drums, to suit different shipping and storage needs. Available unit sizes range from 100g bags to 10kg drums, covering small-batch formulation trials to bulk production-scale orders. Labeling can be customized according to customer requirements.
To maintain product integrity, hydroxypropyl alpha cyclodextrin should be stored in well-closed containers and protected from moisture. Proper storage helps preserve the powder’s physical properties and performance characteristics throughout its shelf life.
