POLYQUATERNIUM-4

Description

Polyquaternium-4 is a versatile cationic polymer widely used in personal care and cosmetic formulations. This synthetic ingredient belongs to the polyquaternium family, known for its positive charge and film-forming properties. Derived from cellulose, Polyquaternium-4 is water-soluble and functions primarily as a conditioning agent and fixative in hair care products.

In hair care applications, Polyquaternium-4 forms a protective film on the hair shaft, enhancing manageability, reducing static, and improving overall texture. Its cationic nature allows it to adhere effectively to negatively charged hair surfaces, providing lasting conditioning benefits. This ingredient is particularly beneficial for damaged or chemically treated hair, as it helps to smooth the cuticle and increase shine.

Beyond hair care, Polyquaternium-4 finds use in skincare formulations as a humectant and film-former. It can help to improve the feel of products and enhance their moisturizing properties. In oral care products, it serves as a thickening agent and helps to bind active ingredients to tooth surfaces.

Polyquaternium-4 is generally considered safe for use in cosmetics, with low potential for skin irritation. Its effectiveness at low concentrations makes it a cost-efficient choice for formulators seeking to improve product performance and consumer satisfaction.
