HYDROXYPROPYLTRIMONIUM HYDROLYZED SILK

Description

Hydroxypropyltrimonium hydrolyzed silk is a multifunctional ingredient derived from silk proteins, widely used in hair and skincare formulations. This quaternary ammonium compound is created by chemically modifying hydrolyzed silk to enhance its cationic properties, allowing it to adhere effectively to hair and skin surfaces.

The ingredient functions primarily as a conditioning agent, imparting a smooth, silky feel to hair and skin. It forms a protective film that helps reduce moisture loss, improve combability, and enhance shine in hair care products. In skincare, it provides a light, non-greasy moisturizing effect and can help improve the texture of formulations.

Hydroxypropyltrimonium hydrolyzed silk is particularly beneficial for damaged or chemically treated hair, as it can help repair and strengthen the hair shaft. It also exhibits antistatic properties, reducing flyaways and frizz. The ingredient is compatible with a wide range of formulations, including shampoos, conditioners, leave-in treatments, and various skincare products.

While generally considered safe for use in cosmetics, individuals with silk allergies should exercise caution. The concentration used in formulations typically ranges from 0.1% to 2%, depending on the specific product and desired effects.
