Polyquaternium-10: Versatile Conditioning Polymer for Hair and Skin Care

Technical Introduction

Polyquaternium-10 is a cationic cellulose derivative obtained by quaternizing hydroxyethylcellulose. As a water-soluble polymer, it has a strong cationic charge density that allows it to bind to negatively charged surfaces such as hair and skin, improving conditioning, detangling, and overall feel.

• INCI Name: Polyquaternium-10

• Chemical Type: Quaternized cellulose polymer

• Appearance: Free-flowing white to off-white powder

• Charge: Strong cationic

• Solubility: Easily soluble in water; forms clear viscous solutions

• Key Functions: Conditioning, film-forming, viscosity modification

Applications

1. Hair Care

• Shampoos → Reduces combing force, enhances smoothness, adds shine.

• Conditioners → Provides softness, manageability, and anti-static effect.

• Hair treatments & masks → Forms protective film, prevents cuticle damage.

• Styling gels → Improves hold and flexibility.

2. Skin Care & Cleansing

• Facial cleansers → Improves mildness, reduces dryness.

• Body washes & soaps → Leaves skin smooth and conditioned.

• Lotions & creams → Enhances moisturization with a light, non-greasy film.

3. Other Uses

• Baby care products → Very mild, improves combability of fine hair.

• 2-in-1 shampoos → Provides conditioning without heavy silicones.

✅ Advantages

• Excellent conditioning for damaged, dry, or chemically treated hair.

• Film-forming → Protects hair fibers and skin surface.

• Improves foam creaminess in shampoos and body washes.

• Reduces static and frizz, enhancing manageability.

• Provides long-lasting moisturization without greasiness.

• Available in different viscosity grades, giving formulation flexibility.

❓ FAQ

Q1: How is Polyquaternium-10 different from Polyquaternium-7 or Polyquaternium-22?
PQ-10 is cellulose-based (natural origin), providing strong conditioning, whereas PQ-7 and PQ-22 are synthetic copolymers that are easier to formulate with but sometimes lighter in feel.

Q2: Does PQ-10 cause buildup on hair?
It forms a thin protective film, but excessive use (>1%) may cause slight buildup in fine hair.

Q3: Is PQ-10 compatible with sulfate-free shampoos?
Yes, PQ-10 works well in both sulfate-containing and sulfate-free systems.

Q4: Can PQ-10 replace silicones in hair care?
PQ-10 provides conditioning and softness, but does not fully replicate silicone shine and slip — often used together for synergy.

Q5: What viscosity grade should I choose?

• Low viscosity (200–500 cps) → Clear shampoos, light formulations.

• Medium viscosity (1000–2000 cps) → Cream shampoos, body washes.

• High viscosity (2000–3000 cps) → Conditioners, intensive masks.
