POLYQUATERNIUM-4/HYDROXYPROPYL STARCH COPOLYMER

Description

Polyquaternium-4/Hydroxypropyl Starch Copolymer is a multifunctional ingredient widely used in skincare and haircare formulations. This synthetic polymer combines the properties of a quaternary ammonium compound with modified starch, resulting in a versatile compound with both conditioning and film-forming capabilities.

In skincare products, it acts as a film-former, creating a protective barrier on the skin's surface that helps retain moisture and improve product texture. Its cationic nature allows it to adhere well to skin and hair, enhancing the longevity of product effects. The ingredient also exhibits conditioning properties, making it particularly useful in leave-on formulations and hair styling products.

Polyquaternium-4/Hydroxypropyl Starch Copolymer is known for its ability to improve the feel and manageability of hair without weighing it down. In skincare, it can contribute to a smooth, non-greasy finish while helping to distribute and stabilize other active ingredients.

This copolymer is generally well-tolerated and suitable for a wide range of skin types. It's often used in concentrations ranging from 0.1% to 2%, depending on the formulation and desired effects. While it's synthetic, it's considered safe for cosmetic use based on current research and regulatory assessments.
