Polyquaternium-52

Polyquaternium-52 is a synthetic conditioning polymer—a large molecule composed of repeating units with a positive electrical charge. It is derived from petrochemical or plant-based sources and is designed to adhere to the surface of hair fibres.This ingredient functions as a hair conditioner, working to improve the texture, manageability, and appearance of hair by forming a protective layer. It is commonly found in rinse-off hair care products such as conditioners and treatment masks, where it can be easily removed during washing.

Polyquaternium-52 is positively charged, which allows it to bind electrostatically to hair fibres—which carry a negative charge. This electrostatic attraction causes the polymer to coat the hair surface, creating a smoother, more uniform structure.By filling microscopic gaps and irregularities along the hair shaft, this coating reduces friction between adjacent fibres. This mechanism decreases static electricity, improves slip during combing, and creates conditions that enhance shine and reduce frizz perception.

Use polyquaternium-52-containing products as a rinse-off conditioner or treatment mask after shampooing. Apply to the mid-lengths and ends of damp hair, leave for the time specified on the product, then rinse thoroughly. For best results, use consistently as part of your regular hair care routine. If you have fine or thin hair, you may prefer lighter conditioners to avoid product build-up.

Polyquaternium-52 is generally well-tolerated and approved for cosmetic use in rinse-off hair products. It is not intended for skin contact; ensure the product is thoroughly rinsed from hair and scalp during washing.
