Polyquaternium-44

Polyquaternium-44 is a synthetic conditioning polymer derived from cellulose. It carries a positive electrical charge, which allows it to bond to the negatively charged surface of hair and skin.In skincare formulations, it functions primarily as an antistatic agent and film former. It creates a lightweight coating that can help reduce frizz and improve the tactile feel of products, though its use in skincare is less common than in haircare.

Polyquaternium-44 is a positively charged polymer that adheres to the negatively charged outer layer of the skin and hair. This electrostatic attraction allows it to coat the surface, smoothing irregularities and reducing the electrical charge that causes static.The film it forms is typically thin and breathable, designed to improve feel and appearance rather than provide occlusive hydration.

Polyquaternium-44 is typically a background ingredient in formulations rather than an active treatment. It is most effective in leave-on products, conditioners, serums, and lightweight moisturisers. Allow the product to fully absorb before applying additional layers to avoid a tacky feel.

Polyquaternium-44 is generally well-tolerated and approved for cosmetic use. It is unlikely to cause irritation at typical concentrations, though those with very sensitive skin may wish to patch test first.
