Product Introduction

Polyquaternium-22 is a synthetic cationic polymer, frequently used in the cosmetic industry for its conditioning and antistatic properties [1]. It is a copolymer of dimethyl diallyl ammonium chloride and acrylic acid, offering excellent compatibility with a wide range of surfactants. This polymer is globally approved for use in cosmetic formulations, functioning as a film former and fixative agent.

Production Process

The production of polyquaternium-22 involves the copolymerization of dimethyl diallyl ammonium chloride (DMDAAC) and acrylic acid, with the reaction typically carried out in an aqueous solution. The process usually includes the use of a radical initiator to facilitate the polymerization, and precise control of temperature and reactant concentrations is crucial. Post-polymerization, the product is often purified to remove residual monomers and other impurities, ensuring a high-quality polymer for cosmetic applications [2].

Efficacy and Function

Polyquaternium-22 provides several benefits in cosmetic formulations, including enhanced conditioning, detangling, and manageability of hair [3]. It forms a clear, flexible film on the skin and hair, offering moisturizing and protective effects. The polymer also helps to reduce static electricity and improve the overall sensory feel of the product.

Application Scenarios

Polyquaternium-22 is widely used in hair care products, like shampoos, conditioners, hairsprays, and styling gels, due to its substantivity and conditioning effects. In skin care, it can be found in lotions, creams, and body washes, contributing to a soft, smooth feel [4]. Its ability to improve the spreadability and texture of formulations makes it a versatile ingredient for various personal care products.

Packaging and Transportation

Polyquaternium-22 is typically packaged in plastic drums or containers, with sizes varying according to customer needs. Transportation should adhere to standard chemical shipping regulations, and storage should be in a cool, dry place away from direct sunlight and incompatible substances. Containers must be tightly sealed to prevent contamination and maintain product integrity.
