INCI Name Polyquaternium-10
CAS Number 68610-92-4 and 81859-24-7
Polyquaternium-10 is a quaternized polymer derived from hydroxyethyl cellulose. It serves as a highly effective conditioning agent, anti-static agent, film former, thickener, and fixative in skincare and hair care products. Known for its conditioning properties, it is a key ingredient in most cosmetic formulations. It appears as a white granular powder with a mild amine-like odor.
Purpose
Polyquaternium-10 is a versatile conditioning agent known for its antistatic, film-forming, and humectant properties. It effectively reduces static in hair, improving manageability and smoothness. As a film-forming agent, it creates a protective barrier that enhances moisture retention and softness. Additionally, its humectant nature helps attract and retain water, preventing dryness in both hair and skin.

Cationic Nature & Strong Affinity for Hair and Skin
Polyquaternium-10, a positively charged polymer, binds effectively to negatively charged hair and skin surfaces. It enhances conditioning, improves the deposition of active ingredients, and reduces friction between hair strands, minimizing damage and breakage.
Film-Forming Ability & Moisture Retention
It forms a lightweight, breathable layer that improves moisture retention, prevents dehydration, and protects hair from environmental aggressors such as pollution and UV exposure.
Anti-Static & Frizz Control
With anti-static properties, it neutralizes static electricity in hair, reducing flyaways and frizz while enhancing smoothness and manageability.
Water-Solubility & Ease of Formulation
Being water-soluble, it dissolves easily in formulations, enhancing texture and viscosity in liquid-based cosmetics.
Compatibility with Surfactants & Conditioning Agents
It is highly compatible with anionic, nonionic, and amphoteric surfactants in shampoos and cleansers, enhancing the conditioning effect of other ingredients for improved softness.
Humectant & Moisturizing Properties
As a humectant, it attracts and retains water, preventing dryness in both hair and skin while maintaining hydration levels in rinse-off and leave-on products.
Non-Irritating & Gentle on Skin & Scalp
It is non-irritating and gentle, making it suitable for sensitive formulations without causing buildup or greasiness.
Foam Stability & Product Performance
Polyquaternium-10 enhances foam stability in shampoos and cleansers, creating a creamier and richer lather that improves product performance even after rinsing.
Hair Detangling & Slip
It smooths the hair cuticle, making combing and brushing easier while minimizing breakage.
Lightweight Conditioning Without Build-Up
Its lightweight conditioning effect ensures that hair remains soft and manageable without feeling heavy or greasy, making it ideal for all hair types, even in frequent-use formulations.
