Slow Sustain Released Retinol 

 Slow Released Retinol [product introduction] Medicinal grade hydroxypropyl- β- Cyclodextrin is used as an encapsulation carrier to produce slow released retinol under vacuum/nitrogen conditions. Hydroxypropyl β- Cyclodextrin undergoes self-assembly during the preparation process, becoming a hydrophobic core and hydrophilic material polymer micelles with water shell. In polymer micelles, based on hydrophobic interactions and similar solubility theory, its hydrophobic core can load the lipophilic component retinol through physical interactions. The unique conical hollow cylindrical three-dimensional ring structure of hydroxypropyl- β- Cyclodextrin can load a large amount of retinol, which will enter the hydroxypropyl group in a molecular state without changing the its structure, in this way, the retinol will be protected in the cavity of cyclodextrin in this way effectively reduce photolysis, oxidation, and thermal damage, and improve the stability of retin…
