Hydroxypropyl cyclodextrin - The mystery of "molecular capsules" in cosmetic formulas

Hydroxypropyl cyclodextrin is a water-soluble polymer and a cyclic starch molecule. It forms a hollow spherical molecular structure, creating a unique "molecular capsule" that can encapsulate other molecules or compounds to increase their stability, solubility, and absorption. In cosmetics, hydroxypropyl cyclodextrin is commonly used as a moisturizer, stabilizer, and emulsifier.

Hydroxypropyl cyclodextrin has no significant side effects on the skin and does not directly cause acne or other skin problems. Some individuals may be allergic to cosmetics containing hydroxypropyl cyclodextrin, especially those allergic to starch or other polymers. If you are concerned about an allergic reaction, please perform a skin test before use.

Many cosmetics contain hydroxypropyl cyclodextrin, such as day creams, night creams, face masks, cleansers, and conditioners. You can check the ingredient list for "hydroxypropyl cyclodextrin" to confirm if a product contains this ingredient.

The main functions of hydroxypropyl cyclodextrin in cosmetics are to enhance product stability and absorption, and to provide moisturizing and protective effects. It can help the skin absorb other beneficial ingredients, thereby improving product efficacy. Hydroxypropyl cyclodextrin can also prevent oxidation, reduce skin inflammation and irritation, and promote cell regeneration and repair. Overall, hydroxypropyl cyclodextrin is a safe and effective cosmetic ingredient for most people.
