Uses:
Polyquaternium-7 (often referred to as PQ-7 or M550) is a highly effective, cationic copolymer derived from diallyldimethylammonium chloride (DADMAC) and acrylamide. In its pure cosmetic grade form, it typically appears as a colorless to pale yellow viscous liquid.
Because it carries a permanent positive charge, it is naturally attracted to the negative charges found on damaged hair and skin. This electrostatic attraction is the foundation of its multifunctional performance in personal care formulations.
Here are the primary selling points and uses of Polyquaternium-7 in the cosmetics industry:
1. Superior Hair Conditioning & Detangling
PQ-7 is a cornerstone ingredient in shampoos, conditioners, and hair styling products. Its positively charged polymer chains adsorb onto the negatively charged hair cuticle, creating a thin, smooth film.
Selling Points: It significantly reduces friction between hair strands, providing excellent "slip" for easy wet and dry combing. It imparts a luxurious softness, shine, and smoothness to the hair without causing heavy build-up.
2. Antistatic & Frizz Control
By neutralizing the negative charge on the hair surface, PQ-7 effectively eliminates static electricity.
Selling Points: It prevents flyaway hair and controls frizz, making it highly valuable for hair care products targeting dry climates or static-prone hair.
3. Foam Enhancement & Stabilization
In cleansing products like shampoos and body washes, PQ-7 works synergistically with anionic surfactants.
Selling Points: It stabilizes and enriches the lather, providing a denser, creamier, and more luxurious foam experience for the consumer. It also helps increase the viscosity of the formulation.
4. Skin Hydration & Velvety Feel
In skincare products like lotions, body washes, and shaving creams, PQ-7 acts as a humectant and emollient.
Selling Points: It attracts and binds water molecules, forming a light, breathable film that locks in moisture. It imparts a smooth, velvety, and non-greasy feel to the skin, enhancing the overall sensory experience and reducing the tight, dry feeling after cleansing.
5. Skin Protection & Reduced Irritation
Selling Points: By forming a protective barrier on the skin, PQ-7 helps mitigate the potential drying or irritating effects of harsh surfactants in cleansing formulations, making products gentler and safer for sensitive skin.
6. Excellent Formulation Compatibility
Selling Points: PQ-7 is highly stable across a wide pH range and exhibits excellent compatibility with anionic, non-ionic, and cationic surfactants. It does not cause cloudiness, precipitation, or separation in formulations, making it a highly versatile and cost-effective ingredient for chemists.
Safety Note: Clinical tests indicate that Polyquaternium-7 is not a sensitizer or photosensitizer and is considered safe for use in cosmetic applications, as it is unlikely to be significantly absorbed into the skin.
