Polyquaternium-22: Versatile Cationic Copolymer for Hair, Skin, and Cleansing Systems

Technical Introduction

Polyquaternium-22 is a cationic copolymer made from acrylamide and diallyldimethylammonium chloride (DADMAC). It is amphoteric in nature, meaning it contains both cationic and anionic groups, which makes it compatible across a wide pH range and with various surfactant systems.

• INCI Name: Polyquaternium-22

• Chemical Type: Amphoteric copolymer (cationic + anionic functionalities)

• Appearance: Clear to slightly hazy viscous liquid

• Charge: Cationic (quaternary ammonium)

• Solubility: Soluble in water; stable across wide pH ranges

• Key Function: Film-forming, conditioning, and viscosity enhancement

Applications

1. Hair Care

• Shampoos & Conditioners → Improves wet & dry combability, softness, and manageability.

• Styling Products → Provides flexible hold and anti-static effect without build-up.

• Hair Serums → Enhances shine and reduces frizz.

2. Skin Care

• Body Washes & Facial Cleansers → Reduces irritation from surfactants, improves skin feel.

• Creams & Lotions → Film-forming for moisturization and smooth after-feel.

• Shaving Products → Provides glide and conditioning.

3. Household & Industrial

• Hand soaps & dishwashing liquids → Improves mildness and after-feel.

• Fabric care products → Imparts softness and antistatic properties.

• Surface cleaners → Enhances deposition of active agents.

✅ Advantages

• Excellent conditioning for both hair and skin.

• Compatible with anionic, cationic, nonionic, and amphoteric surfactants.

• Film-forming ability improves long-lasting moisturization and hair protection.

• Provides anti-static and anti-frizz effects in hair products.

• Enhances foam stability in cleansing formulations.

• Stable over a broad pH range (4–12).

• Non-greasy deposition, prevents buildup.

❓ FAQ

Q1: How does Polyquaternium-22 compare to Polyquaternium-10?
PQ-22 is liquid-based and amphoteric, making it more compatible across surfactant systems, while PQ-10 (cationic cellulose) is powder-based and stronger in conditioning.

Q2: Is Polyquaternium-22 suitable for sulfate-free shampoos?
Yes, it is compatible with sulfate-free and mild cleansing systems.

Q3: Does it build up on hair?
No, unlike some cationic polymers, PQ-22 deposits a light, flexible film that rinses easily.

Q4: What is the recommended use level?
Typically 0.5–2% in shampoos and body washes; up to 5% in conditioners or styling products.

Q5: Can it enhance foam in cleansers?
Yes, it stabilizes foam and improves creaminess, especially in body washes.
