HYDROXYPROPYL CYCLODEXTRIN

Description

Hydroxypropyl cyclodextrin (HP-β-CD) is a modified cyclodextrin molecule widely used in skincare and pharmaceutical formulations. This versatile ingredient is derived from starch and features a truncated cone-shaped structure with a hydrophilic exterior and a lipophilic interior cavity. HP-β-CD's unique structure allows it to form inclusion complexes with various active ingredients, enhancing their solubility, stability, and bioavailability.

In skincare products, HP-β-CD serves multiple functions. It acts as a penetration enhancer, facilitating the delivery of active ingredients deeper into the skin layers. This property is particularly beneficial for formulations containing retinoids, antioxidants, and other challenging-to-formulate actives. HP-β-CD also demonstrates skin-conditioning properties, helping to maintain moisture balance and improve overall skin texture.

Moreover, HP-β-CD exhibits antioxidant capabilities, offering protection against free radical damage. Its ability to complex with and stabilize volatile compounds makes it valuable in fragrance retention and extending product shelf life. HP-β-CD is generally well-tolerated by most skin types and is considered safe for use in cosmetic formulations. Its versatility and efficacy make it a valuable ingredient in a wide range of skincare products, from serums and creams to sunscreens and anti-aging formulations.
